Eight energy majors commit to reduce methane emissions within natural gas industry

November 23, 2017

BP, Eni, ExxonMobil, Repsol, Shell, Statoil, Total and Wintershall committed to reduce further methane emissions from the natural gas assets they operate around the world. The energy companies also agreed to encourage others across the natural gas value chain—from production to the final consumer—to do the same.

The commitment was made as part of wider efforts by the global energy industry to ensure that natural gas continues to play a critical role in helping meet future energy demand while addressing climate change. Since natural gas consists mainly of methane, a potent greenhouse gas, its role in the transition to a low-carbon future will be influenced by the extent to which methane emissions are reduced, the partners said.

UC Santa Barbara team develops catalytic molten metals for direct conversion of methane to hydrogen without forming CO2

November 17, 2017

Researchers at the University of California Santa Barbara have developed catalytic molten metals to pyrolize methane to release hydrogen and to form solid carbon. The insoluble carbon floats to the surface of the melt, where it can be removed and stored or incorporated into composite materials. This method also avoids carbon formation on steam-reforming catalysts, which usually deactivates the catalysts.

In a paper in the journal Science, the team reported that a 27% Ni–73% Bi alloy (Ni0.27Bi0.73) achieved 95% methane conversion at 1065°C in a 1.1-meter bubble column and produced pure hydrogen without CO2 or other by-products. Under these conditions, the equilibrium conversion is 98%. When the temperature was reduced to 1040 °C, the CH4 conversion decreased to 86%.

Global Carbon Project reports global CO2 emissions suddenly on the rise after 3-year hiatus; need for reducing uncertainties

Global emissions of carbon dioxide from burning fossil fuels have risen again after a three year hiatus, according to new analysis from the Global Carbon Project (GCP). According to the GCP, global emissions from all human activities will reach 41 billion tonnes in 2017, following a projected 2% rise in burning fossil fuels.

The researchers, from major international institutions, highlighted that persistent uncertainties exist in our ability to estimate recent changes in emissions, particularly when there are unexpected changes as in the last few years. They also stressed the importance of addressing that fundamental issue.

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. The results suggest that India is becoming, if it is not already, the world’s top sulfur dioxide emitter. The open access study is published in the journal Scientific Reports.

Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems. It is produced predominantly when coal—which typically contains up to 3% sulfur—is burned to generate electricity.

Study concludes 20% synthetic diesel blend could reduce PM emissions in Beijing by ~19%

November 09, 2017

PM emissions from current vehicles in Beijing could be reduced by approximately 19% by simply blending 20% synthetic diesel with currently available diesel, according to a new study by Tsinghua University, the Desert Research Institute in Nevada and Greyrock Energy, a developer of gas-to-liquids technology. This improvement can be accomplished with no changes to the current vehicle fleet, no material changes to infrastructure and no involvement by the consumer.

Other benefits from a 20% fuel blend include reductions in carbon monoxide (CO), nitrogen oxides (NOx), and methane (CH4) emissions by a projected 24%, 5.5%, and 11%, respectively. The control of CH4 emissions is important since it is approximately 84 times more potent as a greenhouse gas than CO2, measured over a 20-year period. Additional advantages of synthetic fuel use include improved fuel economy, enhanced vehicle performance and increased engine life.

UMTRI study shows wide global variability in GHG emissions from operating an EV

November 07, 2017

A team at the University of Michigan Transportation Research Institute (UMTRI) study has assessed the relative amounts of greenhouse-gas emissions from driving a battery-electric vehicle (BEV) compared with greenhouse-gas emissions from driving a traditional gasoline-powered vehicle in different countries of the world.

Indirect emissions from BEVs depend on the mix of fuel sources used to generate electricity; countries differ widely in their fuel-source mix. For example, Albania (which generates 100% of its electricity from hydroelectric power) would have an average 5,100.0 MPGghg (0.05 L/100 km) for a BEV; on the other extreme are Botswana and Gibraltar (which generate 100% of their electricity from coal and oil), each with 29.0 MPGghg (8.1 L/100 km). The corresponding value for the US is 55.4 MPGghg (4.2 L/100 km)—interestingly, close to the 54.5 mpge target for the US EPA’s current GHG regulations for 2025. The average for the world is 51.5 MPGghg (4.6 L/100 km).

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. New NASA-funded research has devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to differentiate among three different sets of conditions that lead to its production.

These observations may also assist air quality managers in assessing the most effective approaches to emission reduction programs that will improve air quality. A study describing the research is published in Journal of Geophysical Research: Atmospheres, a publication of the American Geophysical Union.

Tsinghua study finds China’s actions have cut PM2.5 concentrations 21.5% from 2013-2015; PM2.5-related mortality down 9.1%

Air pollution in China, especially in mega-metropolitan areas, is a matter of concern due to its impact on public health; outdoor PM2.5 exposure contributed to approximately 1.22 million deaths in China in 2013. China’s measures to improve its air quality are working, but more stringent policies should be put in place to safeguard public health, according to a new open-access study by researchers at Tsinghua University published in the journal Environmental Research Letters.

The study used satellite-derived aerosol optical depth measurements, ground based observations, and air quality simulations to evaluate the air quality and health benefits associated with China’s stringent policies implemented during 2013-2015.

FPT Industrial unveils new Cursor 13 natural gas heavy-duty engine

FPT Industrial has introduced its newest and most powerful natural engine. The Cursor 13 Natural Gas is the most powerful 100% natural gas engine available on the on-road segment market today, and is the first purely NG engine on the market specially developed for long-haul missions.

The Cursor 13 NG delivers power up to 460 hp @ 1,900 rpm and torque up to 2,000 N·m @ 1,100 rpm—15% more power and 18% more torque than FPT Industrial’s 8.7-liter NG engine. Cursor 13 NG is a mono-fuel 100% Natural Gas and an easy-to-use solution for end-users, since it can run with CNG (Compressed Natural Gas), LNG (Liquefied Natural Gas) starting from “methane number” 70 and bio-methane. The bio-methane solution is capable of reducing CO₂ emission levels near zero.

Cursor13NG_02

The use of bio-methane has the added benefit of reducing dependency from fossil fuels, as it can be generated from agricultural and urban waste, sewage, or waste from the food industry. It can be produced locally, significantly reducing the need for transporting energy and the related CO₂ emissions. In addition, its production process creates valuable by-products, such as bio-CO₂ for refrigerated units and bio-fertilizer for agriculture.

The new Cursor 13 NG engine, as well as other FPT Industrial NG engines, uses stoichiometric combustion to generate its power. Since 1995 this has been FPT Industrial’s chosen technology, and has proven to be a viable and cost-efficient solution available today to meet Euro VI Step C emission limits.

Chart

The Cursor 13 NG complies with this standard with a simple and easy-to-install 3-way catalyst with no-EGR, no-SCR and no-DPF (regeneration free solution). The new engine’s CO₂ emission level is lower (-9%) compared to diesel and can reach near zero by using bio-methane. At the same time, Cursor 13 NG allows a 98% PM reduction and NOx emissions which are 48% lower when compared to Euro VI compliant diesel engines.

Furthermore, Natural Gas engines decrease noise pollution with a smoother and quieter engine combustion cycle (Otto cycle, 12:1 compression ratio, far below the 17:1 ratio of the Diesel cycle), slashing vehicle noise pollution operation at less than 71 dB.

The EGR-free combustion, as well as the multipoint fuel injectors and fuel rails, grant class leading fuel consumption: fuel cost savings is up to 30%-40% (depending on the fuel cost) compared to the Cursor 460 hp diesel engine. The new Cursor 13 NG engine achieves high reliability standards both on mechanical and thermal stress thanks to the Nickel-Resist cast-iron exhaust manifold, water cooled wastegate turbocharger and Compacted Graphite Iron (CGI) cylinder head.

Cursor13NG_04

FPT Industrial’s lean technology that avoids diesel and Ad-Blue for SCR supports a lighter and more compact solution, allowing optimization of the truck payload and space availability. This attribute enables mounting more capacious fuel tanks on the vehicle, widening the mission range.

The FPT Industrial Cursor 13 NP engine is protected by two patents: the first, for which patent protection is in progress, is the FPT Industrial proprietary knock control that makes it possible to increase the performance, enables the widest fuel compatibility, and protects engine and 3-way catalyst from misfiring. The second one is FPT Industrial’s proprietary reactive air-flow control management system, a new stoichiometric ratio control logic that is applied during gearshifts. This ensures a continuous torque delivery when coupled with AMT gearshifting, which enables maximized performance and the fastest gearshift.

Sandia, TUD optical diagnostic helps reduce emissions while improving fuel economy

A team of researchers at Sandia’s Combustion Research Facility and the Technical University of Denmark have developed an optical setup for quantitative, high-temporal resolution line-of-sight extinction imaging in harsh optical environments. The diagnostic tool can now quantify the formation of particulate matter as a function of time and space for a variety of combustion processes. The work was published in a paper in the journal Applied Optics.

Initially, the researchers have focused on the combustion of liquid fuel sprays found in engines, where the extreme pressures and temperatures create an environment that is optically challenging. To meet future particulate matter emissions mandates without sacrificing fuel savings, engine developers need advanced combustion strategies to reduce the formation of soot in spray flames.

Large scale epidemiological study associates PM2.5, NO2 pollution with kidney, bladder and colorectal cancer death

October 31, 2017

Air pollution is classified as carcinogenic to humans given its association with lung cancer, but there is little evidence for its association with cancer at other body sites. However, in a new large-scale prospective study led by the Barcelona Institute of Global Health (ISGlobal), an institution supported by the “la Caixa” Foundation, and the American Cancer Society, researchers observed an association between some air pollutants and mortality from kidney, bladder and colorectal cancer.

The open-access study, published in Environmental Health Perspectives, included more than 600,000 adults in the US who participated in the Cancer Prevention Study II and who were followed for 22 years (from 1982 to 2004). The scientific team examined associations of mortality from cancer at 29 sites with long-term residential exposure to three ambient pollutants: PM2.5, nitrogen dioxide (NO2) and ozone (O3).

UN Environment report says national GHG pledges only bring one-third of reductions needed for Paris Agreement

The eighth edition of UN Environment’s Emissions Gap report, released ahead of the UN Climate Change Conference in Bonn, finds that national pledges only bring approximately one-third of the reduction in emissions required by 2030 to meet climate targets, with private sector and sub-national action not increasing at a rate that would help close this gap.

The Paris Agreement looks to limit global warming to under 2 ˚C, with a more ambitious goal of 1.5 ˚C also on the table. If the emissions gap is not closed by 2030, the report says, it is extremely unlikely that the goal of holding global warming to well below 2 ˚C can still be reached. Even if the current Nationally Determined Contributions (NDCs) are fully implemented, the carbon budget for limiting global warming to below 2 ˚C will be about 80% depleted by 2030. Given currently available carbon budget estimates, the available global carbon budget for 1.5 ˚C will already be well depleted by 2030.

Insights from Leoben researchers lead to improved piezo injectors

One of the elements modern diesel engines require to become energy-efficient and clean are precisely controllable injection nozzles using piezo crystals. How exactly these crystals work has not been fully understood to date. In a project funded by the Austrian Science Fund FWF, a group of researchers from the Materials Center Leoben (MCL) in Austria has now gained insight into the mechanics of this technology—which can make the systems more reliable and efficient. Their results are also of interest for medical applications or energy harvesting.

Diesel engines are currently the object of strong criticism because of their emissions. While the share of nitrogen oxides can be reduced only by adding chemicals or by lower combustion temperatures, the generation of soot depends on the quality of the combustion process itself. To optimize combustion, injection schemes and timing has become complex. The multiple injections need to happen in a fraction of a second and require high precision injection nozzles. Magnetic valves are often too slow, which is why piezo crystals are used.

Dynamically tuning the structure of platinum in catalytic converters to enhance performance under different conditions

October 30, 2017

Researchers from France and Germany are proposing a new concept for the dynamic tuning of the structure of platinum nanoparticles on catalytic converters to enhance their performance—especially after cold starts and in urban traffic—and to reduce the consumption of expensive noble metal. The method is based on the interaction between platinum and the cerium oxide carrier to control catalytic activity by short-term changes of the engine’s operation mode, the team reports in their paper in the journal Angewandte Chemie.

Due to its good catalytic properties, platinum is often applied in catalytic converters of vehicles. Presently, about 60% of the European platinum trade goes to this purpose. Using a diesel oxidation catalytic converter (DOC), the scientists of Karlsruhe Institute of Technology (KIT) and their partners found that the particle size and oxidation state of the platinum component during operation can be modified specifically and dynamically during operation.

Study finds modifying urban form may be a strategy to reduce air pollution

Based on their findings in a new study, researchers from the University of Washington and the University of Minnesota suggest that modifying urban form—as a means of affecting motor vehicle usage—may be a strategy to mitigate urban air pollution. Their paper appears in the ACS journalEnvironmental Science & Technology.

They used satellite-based measurements of urban form and nitrogen dioxideO2 (n) to explore relationships between urban form and air pollution for a global data set of 1,274 cities. The found that three of the urban form metrics (contiguity, circularity, and vegetation) have a statistically significant relationship with urban NO2; their combined effect could be substantial. As an example, if Christchurch, New Zealand matched the urban form of Indio - Cathedral City, California, the models suggest that Christchurch’s NO2 concentrations would be ∼60% higher than its current level.

Study finds cities can reduce CO2 more easily from residential conservation than transportation

A new study by a team from the University of Pennsylvania and MIT suggests it will be easier for cities to reduce CO2 emissions coming from residential energy use rather than from local transportation. This reduction will happen mostly thanks to better building practices, not greater housing density. The study is published in the Journal of Planning Education and Research.

The study used a series of fixed-ratio projections and scenarios to explore the potential for local residential energy conservation mandates and compact growth programs to reduce locally-based CO2 emissions in eleven representative US metropolitan areas. The modeling showed that averaged across all eleven metros, residential energy conservation mandates could reduce residential CO2 emissions in 2030 by an average of 30% over and above 2010 levels.

Study: expanding Brazilian sugarcane for ethanol could reduce global CO2 emissions by up to 5.6%

October 24, 2017

Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global CO2 emissions by as much as 5.6%, according to a new study by an international team led by researchers from the University of Illinois.

This would be a massive undertaking, involving the conversion of hundreds of thousands of square miles—at its most ambitious, more than the combined land area of Texas and California—to sugarcane fields. However, it could be accomplished without impinging on environmentally sensitive areas in Brazil and while allowing for the expansion of other agricultural crops and human needs, the researchers report in a paper in the journal Nature Climate Change. The carbon-related costs of converting the land to sugarcane fields were included in the analysis.

Dearman flags diesel loophole in new London T-Charge anti-pollution scheme

October 23, 2017

Dearman, the UK-based developer of clean cold power systems based on its engine powered by liquid nitrogen (earlier post), has identified a diesel loophole in the new London T-Charge levy on the most polluting vehicles. (Earlier post.)

The £10 (US$13) per day levy applies to vehicles whose main engines do not meet the Euro 4/IV emission standard—i.e. mostly vehicles registered before 2006. Coming in addition to the congestion charge which covers the same area, the 34,000 motorists affected will now have to pay £21.50 (US$28.31) a day to drive their vehicle in the covered area in London. However, Dearman notes, many refrigerated delivery trucks use two diesel engines.

London’s £10 daily “T-charge” for most polluting vehicles now in effect; partnership with Turing Institute

London’s £10 daily “T-Charge” (toxicity), aimed at the oldest, most polluting vehicles on London roads, is now in effect. The T Charge applies mainly to diesel and gasoline vehicles registered before 2006. The T-Charge (officially known as the Emissions Surcharge) operates on top of (and during the same operating times as) the Congestion Charge (Monday to Friday 7am-6pm), so it will cost £21.50 to drive in the zone if a vehicle is affected. Drivers can check the status of their vehicles online.

The minimum emissions standards for avoiding the T-Charge are Euro 4/IV for both gasoline and diesel vehicles and Euro 3 for motorized tricycles and quadricycles. A small number of vehicles manufactured before the Euro 4/Euro IV standard became mandatory will have NOx and PM emissions that meet Euro 4/Euro IV or better. These are designated as early adopters and are not subject to the T-Charge.

October 21, 2017

Pollution is the largest environmental cause of disease and premature death in the world today, according to the newly released report detailing the adverse effects of pollution on global health by the The Lancet Commission on Pollution and Health.

Diseases caused by pollution were responsible for an estimated 9 million premature deaths in 2015—16% of all deaths worldwide—three times more deaths than from AIDS, tuberculosis, and malaria combined and 15 times more than from all wars and other forms of violence. In the most severely affected countries, pollution-related disease is responsible for more than one death in four. The open-access report is published in The Lancet.

Global CO2 emissions stalled for the third year in a row

The annual assessment of global greenhouse gas (GHG) emissions by the JRC and the Netherlands Environmental Assessment Agency (PBL) confirms that CO2 emissions have stalled for the third year in a row. The report provides updated results on the continuous monitoring of the three main greenhouse gases: carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).

Global GHG emissions continue to be dominated by fossil carbon dioxide (CO2) emissions, which however show a slowdown trend since 2012, and were stalled for the third year in a row in 2016.

ICCT study finds GHGs from shipping on the rise

October 20, 2017

Emissions of greenhouse gases (GHGs) from global shipping are on the rise again, according to a new study released by the International Council on Clean Transportation (ICCT). Overall, the study found that maritime fuel consumption increased from 291 to 298 million tonnes (+2.4%) from 2013 to 2015, compared to a 7% increase in shipping transport work. Accordingly, CO2 emissions from global shipping (oceangoing vessels, domestic ships, and fishing vessels) increased from 910 to 932 million tonnes over the same period.

The report notes that these increases in GHG emissions are being driven by the rising demand for shipping and, as a result—despite improvements in operational efficiency for many ship classes—by the increased consumption of fossil fuels.

Global Mobility Report finds world not on track to achieving sustainable mobility

October 19, 2017

The transport sector is not on track towards achieving sustainable mobility, according to the newly published Global Mobility Report 2017 (GMR). The GMR is the first study to assess the global performance of the transport sector and the progress made toward four main objectives: universal access, efficiency, safety, and green mobility. The publication covers all modes of transport, including road, air, waterborne, and rail transport. The report was produced by the Sustainable Mobility for All initiative (SuM4All)—a worldwide consortium of more than 50 leading organizations in the transport sector.

According to the report, apart from being inaccessible to many of the world’s most vulnerable, the transport sector today is plagued by high fossil fuel use, rising greenhouse gas emissions, air and noise pollution, an alarming number of road fatalities, and a reluctance to embrace digitalization.

Study finds air pollution and GHG costs of crude-by-rail nearly 2x pipeline costs; much larger than spill and accidents costs

October 11, 2017

Researchers from Carnegie Mellon University and the University of Pittsburgh have found that the air pollution and greenhouse gas costs of shipping crude by rail are nearly twice as large as those for oil pipelines. Further, their estimates of air pollution and greenhouse gas costs are much larger than estimates of spill and accidents costs—more than twice as big for rail and more than eight times as big for pipelines.

The findings of their study, published by the National Bureau of Economic research, suggest that the policy debate surrounding crude oil transportation has put too much relative weight on accidents and spills, while overlooking a far more serious source of external cost: air pollution and greenhouse gas emissions.

EPA proposes repeal of Obama Clean Power Plan

October 10, 2017

As anticipated, the US Environmental Protection Agency (EPA) has issued a Notice of Proposed Rulemaking (NPRM), proposing to repeal the Clean Power Plan (CPP). Released in 2015 by the Obama Administration EPA, the CPP established the first national standards to limit CO2 emissions from fossil-fuel-fired power plants (Electric Generating Units, EGUs), with a target of a 32% reduction against a 2005 baseline by 2030. (Earlier post.)

The Trump Administration EPA has proposed to determine that the Obama-era regulation exceeds its statutory authority. EPA has now sent the NPRM to the Federal Register for publication. Upon publication, the public will have 60 days to submit comments.

EIA: US energy-related CO2 emissions down 1.7% in 2016; carbon intensity of economy down 3.1%; transportation emissions up

October 06, 2017

US energy-related CO2 emissions decreased by 89 million metric tons (MMmt), from 5,259 MMmt in 2015 to 5,170 MMmt in 2016. Although real gross domestic product (GDP) increased 1.5% over that period, other factors contributing to energy-related CO2 emissions more than offset the growth in GDP, leading to a 1.7% decline in energy-related CO2, according to the latest report from the US Energy Information Administration (EIA).

These contributing factors included a decline in the carbon intensity of the energy supply (CO2/British thermal units [Btu]) of 1.7% along with a 1.4% decline in energy intensity of the economy (Btu/GDP). Combining these two factors, the overall carbon intensity of the economy (CO2/GDP) declined by 3.1%.

New Euro6 trucks from Volvo running on LNG offer the same performance as diesel, but with 20-100% lower CO₂ emissions

October 04, 2017

Volvo Trucks is now introducing Euro 6-compliant heavy duty trucks running on liquefied natural gas or biogas. The new trucks have the same performance, driveability and fuel consumption as Volvo’s diesel-powered models. Furthermore, the new trucks’ CO₂ emissions are 20–100% lower compared with diesel, depending on choice of fuel. The new Volvo FH LNG and Volvo FM LNG are available with 420 or 460 hp for heavy regional and long-haul operations.

Instead of an Otto cycle engine, which is the conventional solution for gas-powered vehicles, the Volvo FH LNG and Volvo FM LNG are powered by gas engines utilizing Diesel cycle technology. This means that an operator who chooses gas can do so without compromising on driveability, fuel efficiency or reliability. Volvo’s 460 hp gas engine delivers maximum torque of 2300 N·m while the 420 hp version produces 2100 N·m. This is the same as Volvo’s corresponding diesel engines. Fuel consumption is on a par with Volvo’s diesel engines, but 15 to 25% lower than for conventional gas engines.

New study suggests PM air pollution damages the kidneys

September 22, 2017

Studies have shown that air pollution can have negative effects on cardiovascular health and life expectancy. Now new research indicates that it is also harmful to the kidneys. The study, which appears in an open access paper in the Journal of the American Society of Nephrology (JASN), shows that the effects on the kidneys are seen at low levels of particulate matter and increase linearly with rising levels of pollution.

Information on the relationship between air pollution and kidney disease is very scarce. To investigate, a team led by Ziyad Al-Aly, MD (Director of Clinical Epidemiology at the VA Saint Louis Health Care System) linked the Environmental Protection Agency (EPA) and the Department of Veterans Affairs databases to examine information on 2,482,737 US veterans who were followed for a median of 8.5 years. Air pollution levels were also assessed using space-borne sensors from NASA satellites.

California Legislature passes $1.5B California Clean Air Initiative to cut emissions; $895M for mobile sources

September 19, 2017

The California state legislature has passed a set of bills (AB 134 and AB 109) providing $895 million towards programs that will reduce air pollution from mobile sources which are responsible for 40% of the state’s greenhouse gas emissions.

Titled the “California Clean Air Initiative,” the bills will invest the bulk of available discretionary revenue (the 40% of cap-and-trade revenue not previously allocated by statute) through incentives to replace old, high-polluting diesel engines in heavy trucks and buses; provide rebates to help low- and middle-income families purchase new and used zero-emission vehicles; and promote zero-emission car-sharing and agricultural van pool programs, among others. The Clean Air Initiative marks the single largest investment in clean air in state history.

T&E concludes that diesel cars emit more CO2 on a full lifecycle basis than gasoline cars

September 18, 2017

A new analysis by the NGO Transport & Environment (T&E) concludes that diesel cars emit more CO2 than equivalent cars on a full lifecycle basis—i.e., accounting for the emissions generated during production of the vehicle and the fuel.

According to the T&E analysis, an average diesel car produces emits 3.65 tonnes more CO2 than an equivalent gasoline car over its lifetime due to a more energy-intensive refining of the diesel fuel; more materials required in the production of heavier and more complex engines; higher emissions from biodiesel blended in the diesel fuel; and longer mileage because fuel is cheaper.

European auto industry proposes further 20% cut in passenger car CO2 by 2030 from 2021; conditional on EV uptake and infrastructure; no ZEV mandate

September 13, 2017

At the Frankfurt Motor Show, the European Automobile Manufacturers’ Association (ACEA) outlined the industry’s proposal for a pathway to future CO2 reductions: a 20% CO2 reduction for passenger cars by 2030, compared to 2021. The European Commission will reveal its proposal on CO2 targets for cars post-2021 later this year.

The ACEA said that this target should be conditional on the real market uptake of electrically-chargeable vehicles and the availability of charging infrastructure for alternatively-powered vehicles which are crucial to achieve any significant CO2 reductions beyond 2020 levels. Based on a mid-term review in 2025, this target could be adjusted either upwards or downwards.

Mazda SPCCI uses spark plug as HCCI control factor; “air piston” to enhance compression

September 08, 2017

Gasoline HCCI (homogenous charge compression ignition) has been of interest to automakers for years, as the low-temperature combustion mode offers significant improvements in thermal efficiency and fuel consumption along with a reduction in NOx emissions compared to conventional spark ignition gasoline engines. However, traditional HCCI combustion has been realized only in a limited operating range. (E.g., Earlier post, earlier post, earlier post.)

With the announcement of its SKYACTIV-X engine (earlier post), Mazda claims to have developed a novel control system for HCCI combustion that extends the HCCI range out to a much larger percentage of the load map. The essence of Mazda’s Spark Controlled Compression Ignition (SPCCI) is the use of the spherical spherical flame front expanded by spark ignition as a second piston (an “air piston”) to further compresses the air-fuel mixture, resulting in improved compression ignition.

ICCT: based on EU government tests, only 10% of Euro 6 cars meet NOx limit in real-world driving conditions

A new study by the independent research organization International Council on Clean Transportation (ICCT) has compiled the test results from government agencies across Europe for 541 Euro 5 and Euro 6 diesel passenger cars. The study found that the average real-world level of nitrogen oxide (NOx) emissions from Euro 6 vehicles is 4.5 times above the Euro 6 limit. Only 10% of Euro 6 cars outperform the Euro 6 limit; the rest of vehicles exceed the Euro 6 standard by up to 12 times.

Up to September 2015, when the news broke about the illegal defeat device used by Volkswagen in the United States, no systematic overview of real-world NOx emission levels by vehicle manufacturer and model had ever been carried out in Europe. Over the ensuing two years, a number of government agencies across Europe began to systematically test diesel cars for their emission levels.

Birmingham study finds butanol-gasoline blend reduces GDI engine-out carbonaceous emissions; similar NOx

September 03, 2017

A team at the University of Birmingham reports that a blend of 33% v/v of butanol in EN228 commercial gasoline containing 5% of ethanol (B33) reduces GDI (gasoline direct injection) engine-out carbonaceous emissions, while maintaining similar levels of NOx emissions when compared to standard gasoline combustion at low and medium engine loads. However, the physical and chemical properties of butanol (i.e. viscosity and heat of vaporization) resulted in a negative impact on carbon monoxide emissions at low load due to combustion inefficiencies.

The addition of EGR showed a general reduction of gaseous emissions and particulate matter (except unburned hydrocarbons), a trend that was more significant for B33 at medium load. EGR improved both Brake Specific Fuel Consumption (BSFC) and Brake Thermal Efficiency (BTE) for the studied fuels with respect to baseline conditions. Their paper is published in the journal Fuel.

California ARB study finds commuters’ exposures to air pollution greatly depends on mode of travel; light rail, personal vehicles the lowest

September 01, 2017

The mode of travel you take on your daily work commute can make a big difference in your exposure to air pollution, according to a new study by researchers at the California Air Resources Board (ARB).

The study, published recently in Atmospheric Environment, investigated commuter exposure to PM2.5, black carbon (BC), and ultrafine particles (UFP) in six common transport microenvironments in Sacramento, California. The researchers found that electricity-powered light rail trains offer the least polluted travel environment followed by personal vehicles, while commute trips by older technology diesel-powered trains experienced the highest average air pollution levels in Sacramento.

WLTP and RDE tests for measuring emissions come into force in EU tomorrow

August 31, 2017

Two new tests for measuring emissions from cars and vans will come into force in the EU tomorrow. The new laboratory test, the Worldwide Harmonized Light Vehicle Test Procedure (WLTP), will introduce more realistic testing conditions for measuring pollutant and CO2 emissions than the previous, outdated lab test (NEDC). It thus provides a more accurate basis for measuring a vehicle’s fuel consumption and emissions.

The real driving emissions (RDE) test, which measures pollutant emissions on the road, also applies as of tomorrow, making Europe the only region in the world to implement such mandatory testing. Under RDE, a car will be driven on public roads over a wide range of conditions using portable measuring equipment (PEMS). RDE will complement WLTP to ensure that pollutant emission levels, measured during the laboratory test, are confirmed on the road.

New ICCT study finds CO2, NOx emissions of Euro 6 diesel and gasoline cars under real-world settings exceeding limits

A new study commissioned by the International Council on Clean Transportation (ICCT) investigates the real-world emissions of four Euro 6 passenger cars—one gasoline and three diesel vehicles with different aftertreatment technologies—tested under variable conditions. The investigation was conducted by the Laboratory of Applied Thermodynamics, of the Aristotle University of Thessaloniki, and its spin-off company, Emisia.

The investigation found that every tested vehicle exceeded its CO2 certification levels in a range varying from 21% to 37% under the laboratory type-approval test using real-word road-load settings. Two of the three diesel vehicles exceeded the NOx limit by 19% and 66% while tested under the laboratory type-approval test. Under RDE-compliant on-road trips, using PEMS emission measurements, NOx emissions from diesel vehicles showed average levels varying from 5 to 16 times the Euro 6 limit.

Digging into the differences in carbon accounting for biofuels

August 24, 2017

The benefit to the climate of using biofuels as a substitute for fossil fuels has been sharply contested for years; much of the disagreement is based on the assumptions underlying the carbon accounting in the lifecycle analysis. The argument essentially boils down to whether or not biofuels are inherently carbon neutral because the CO2 released when they are burned is derived from CO2 uptake during feedstock growth.

A paper and subsequent formal comments and responses in the journal Climatic Change highlights the conceptual differences and the impact on policy. Professor John DeCicco at the University of Michigan Energy Institute has grown increasingly critical of the lifecycle analysis methods used to justify and administer biofuel policies. In a 2016 open-access paper in Climatic Change, he and his colleagues argued that once estimates for process emissions and displacement effects including land-use change are considered, US biofuel use to date is associated with a net increase rather than a net decrease in CO2 emissions.

Bosch study highlights potential of e-fuels to reduce CO2 emissions

August 22, 2017

According to a new study by Bosch, the use of e-fuels—synthetic fuels based on renewable energy—in Europe by 2050 as a scheduled supplement to electrification could save up to 2.8 gigatons of CO2: three times Germany’s carbon-dioxide emissions in 2016.

The calculation is based on an assumed e-fuels blend of 1% in 2025, 10% in 2030, 40% in 2040 and completely replacing the fossil fuel share by 2050.

Empa recommends buying diesel vehicles only if Euro 6d-TEMP or Euro 6d

On 1 September 2017, new emissions regulations for passenger vehicles come into force in the EU and Switzerland. These will plug the gaps in the existing legislation and will help to ensure that diesel vehicles in particular become considerably cleaner as regards their NOx emissions. However, the new regulations also permit existing vehicles to continue to be sold for some time. Empa, the Swiss Federal Laboratories for Materials Testing and Research for Industry, Construction and Commerce, recommends buying diesel vehicles only if they have been approved in accordance with Euro 6d-TEMP or Euro 6d.

At the end of 2016 around 3.1 million passenger vehicles with gasoline engines and 1.3 million with diesel engines were registered in Switzerland. Despite representing only 30% of the country’s entire passenger vehicle fleet, diesel vehicles are responsible for 80% of NOx emissions.

Continental introduces electric Active Purge Pump (APP) to meet stricter hydrocarbon evaporation legislation around the globe

Continental has developed an electrified solution to further reduce hydrocarbon evaporative emissions: the Active Purge Pump (APP). The APP actively pulls HC-laden air from the canister used to control evaporative HC emissions. The pump used for this action is a very compact and light-weight radial pump, driven by a highly efficient brushless DC motor.

The APP can be use on-demand, activated any time when necessary. The APP thus makes canister purging available independent from the engine operation point and vacuum availability. Further, APP’s main function can be extended by integrating algorithms to provide additional functions that either require stand-alone products today or are not even currently available. Start of production is planned for end of 2019.

Ninth annual Green Innovation Index finds California light-duty vehicle emissions spike; major challenge to 2030 climate goals

The ninth annual California Green Innovation Index—released by the nonpartisan nonprofit group Next 10 and prepared by Beacon Economics—finds that the state’s ambitious climate policies have allowed for considerable economic growth, with California outpacing the growth of other states during the recovery period following the Great Recession. Between 2006 and 2015, California’s GDP per capita grew by almost $5,000 per person, nearly double the growth experienced by the US as a whole. At the same time, per capita emissions in the state decreased by 12%. Job growth between 2006 and 2015 in California outpaced rates experienced prior to 2006, and outpaced total US employment gains by 27%.

However, although the state has made considerable progress decoupling economic growth from greenhouse gas (GHG) emissions, the rate of emissions decline appears to be slowing, due in part to a spike in transportation emissions attributed to an increase from light-duty vehicles. On an absolute basis, California’s total GHG emissions fell only slightly in 2015, down 0.34% from 2014. This compares to a 0.73% reduction in the previous year and sharper falls in years before.

EMA concerned that EPA’s revisiting Phase 2 GHG rules could lead to misaligned regulatory requirements

Last week, the Environmental Protection Agency (EPA) announced its intent to revisit provisions of the second phase of the greenhouse gas and fuel efficiency rules for medium- and heavy-duty on-highway trucks and engines that were finalized last year. (Earlier post.) The Phase 2 program builds on the Phase 1 regulations that manufacturers have successfully implemented starting in 2014.

While the new regulations are significantly more ambitious and complex than the Phase 1 requirements, the Truck and Engine Manufacturers Association (EMA) and its members have consistently supported their implementation. EMA is now concerend that EPA’s revisiting the rule could lead to a misalignment of regulatory requirements.

Purdue, Notre Dame, Cummins discovery could lead to new SCR catalyst design for improved NOx control

August 18, 2017

Researchers at Purdue University, the University of Notre Dame and Cummins have discovered a new reaction mechanism that could be used to improve SCR catalyst designs for pollution-control systems to further reduce emissions of smog-causing nitrogen oxides in diesel exhaust. The research focuses on zeolites—workhorses in petroleum and chemical refineries and in emission-control systems for diesel engines.

The key challenge in reducing emissions is that they can occur over a very broad range of operating conditions, and especially exhaust temperatures,” explained Rajamani Gounder, the Larry and Virginia Faith Assistant Professor of Chemical Engineering in Purdue University’s Davidson School of Chemical Engineering. “Perhaps the biggest challenge is related to reducing NOx at low exhaust temperatures, for example during cold start or in congested urban driving.” Current NOx reduction technologies only work well at relatively high temperatures.

Metabolomics study finds exposure to PM2.5 leads to increases in stress hormones

August 15, 2017

Exposure to high levels of PM2.5 air pollution increased stress hormone levels and negative metabolic changes in otherwise healthy, young adults according to the findings of a recent study conducted in China. Air purifiers appear to lessen the negative effects. The research is published in the American Heart Association’s journal Circulation.

The researchers focused on PM2.5—a component of air pollution emitted from vehicles, factories, power plants, fires and smoking—because many studies have suggested this type of major air pollutant might lead to cardiovascular and metabolic health consequences, according to Haidong Kan, M.D., Ph.D., study author and professor of environmental health sciences at Fudan University in Shanghai, China.

New Federal-Mogul Powertrain high thermal conductivity seats and guides keep engine valves cooler; improved combustion, lower emissions

August 14, 2017

Federal-Mogul Powertrain will debut new materials for valve seats and guides with improved thermal conductivity at the 2017 IAA Show in Frankfurt, Germany next month. Suitable for series production, the new High Thermal Conductivity (HTC) materials and Thermal Interface Material (TIM) coating can reduce valve head temperatures by up to 70°C, allowing improved combustion and lower emissions.

HTC can also contribute in obtaining a more even circumferential temperature distribution on the valve seat insert and surrounding cylinder head material, eliminating local hot spots for the benefit of wear reduction and decrease of temperature-related distortion.

Recent on-road real-world emission testing in India highlights disparity between cycles, gasoline and diesel

The International Council on Clean Transportation (ICCT) recently contracted with the International Centre for Automotive Technology (ICAT) of India to conduct laboratory and on-road testing of three in-use passenger vehicles—two diesel and one gasoline—to investigate the real world emission performance of passenger vehicles in Indian roads. The results highlight the disparity between test-cycles and real-world emissions as well as the large disparity between gasoline and diesel vehicles.

For laboratory testing, they measured emissions under the Modified Indian drive cycle (MIDC) (similar to NEDC), and the World harmonized Light Duty test cycle (WLTC); cold and hot start tests were performed for each vehicle and drive cycle.

WUSTL study finds use of air conditioning reduces in-car pollution

August 11, 2017

Traffic is a major source of harmful pollutants; daily peak exposures tend to occur near roadways or while traveling—or being stuck—on them. For example, a team at the University of Surrey found that particulate pollution levels inside cars are up to 40% higher when the vehicle is stuck in a traffic jam or stopped at a red traffic light compared to free-flowing traffic conditions. (Earlier post.)

A team at the University of Washington in St Louis has now measured simultaneous real-time particulate matter (particle numbers, lung-deposited surface area, PM2.5, particle number size distributions) and CO concentrations outside and in-cabin of an on-road car during regular commutes to and from work. Data was collected for different ventilation parameters (windows open or closed, fan on, AC on), while traveling along different road-types with varying traffic densities. They found that car drivers can expect their highest exposures when driving with windows open or the fan on, and their lowest exposures during windows closed or the AC on. Their paper is published in Atmospheric Environment.

BMW defends diesel while pushing electrification

BMW has established solid electrification credentials. With BMW i, the BMW Group was the first German manufacturer to make a clear commitment to electromobility, notes BMW AG Management Board Chairman Harald Krüger. In 2017, the BMW Group expects sales of its electrified vehicles to exceed 100,000 for the first time in a single year, with the all-electric BMW i3, BMW i8, BMW iPerformance plug-in hybrids and the plug-in hybrid MINI Countryman all contributing to the figures. The company’s electrified range currently comprises nine electrified vehicles and will be further complemented in 2018 by the all-new BMW i8 Roadster.

Shortly after that, BMW Group will roll out battery-only solutions across its core brands, with Plant Oxford starting production of the battery-powered MINI in 2019, and the battery-only BMW X3 following in 2020. The following year, 2021, will see the launch of the BMW Group’s new technology spearhead: the all-electric BMW iNEXT. Nonetheless, says Krüger, “Future mobility will definitely depend on state-of-the-art diesels as well, because environmental protection has several dimensions: one of them is the fight against climate change.

California ARB approves cap-and-trade amendments; linking with Ontario

Following more than 18 months of review and public comment, the California Air Resources Board (CARB) approved amendments to the state’s cap-and-trade program that improve its implementation and the state’s effort to curb greenhouse gas emissions. The amendments also establish a framework for the program’s annual limits on greenhouse gas emissions beyond 2020, to be revised in a subsequent, public rulemaking process to reflect the requirements of AB 398.

The Board action includes adopting amendments that have been in development since late 2015, and were first heard by the Board in September 2016. The amendments include linking with Ontario, which launched its own cap-and-trade program earlier this year. The Canadian province is expected to link with California’s program in 2018, becoming the second jurisdiction to join California following Quebec in 2014. Additionally, the Oregon legislature is considering a measure to establish a cap-and-trade system that is compatible with California’s.

UK unveils new plan to cut NO2; sale of new conventional gasoline and diesel cars to end by 2040; focus on local action

July 26, 2017

The UK Government unveiled its new plan to reduce roadside nitrogen dioxide (NO2) concentrations in the shortest amount of time. Among the many policy and funding details in the UK Plan for Tackling Roadside Nitrogen Dioxide Concentrations, produced by Defra and the Department for Transport is the cessation of the sale of all new conventional gasoline and diesel cars by 2040. Another element in the plan includes possible civil and criminal charges against manufacturers implementing emissions defeat devices, with fines of up to £50,000 (US$65,000) per instance.

The NO2 plan is one element in the Government’s efforts to deliver clean air. In 2018, the Government will publish a comprehensive Clean Air Strategy which will address other sources of air pollution. Air quality in the UK has been improving significantly in recent decades, with reductions in emissions of all of the key pollutants, and NO2 levels down by half in the last 15 years. Despite this, an analysis of more than 1,800 major roads show that a small number of these—81 or 4%—are due to breach legal pollution limits for NO2, with 33 of these outside of London.

Study finds in-car rush-hour exposure to some particulate pollution twice as high as previously thought

July 23, 2017

A new study, part of the Atlanta Commuter Exposures (ACE) Study, has assessed on-roadway in-cabin particulate pollution (PM2.5) collected from scripted rush hour commutes on highways and on non-highway side streets. Reported in the journal Atmospheric Environment, the study found that levels of some forms of harmful particulate matter inside car cabins are twice as high as previously believed.

Most traffic pollution sensors are placed on the ground alongside the road and take continuous samples for a 24-hour period. Exhaust composition, however, changes rapidly enough for drivers to experience different conditions inside their vehicles than these roadside sensors. Long-term sampling also misses nuanced variabilities caused by road congestion and environmental conditions.

Researchers characterize aggregate indoor and outdoor PM2.5 exposure

In an initial step toward developing a comprehensive global impact assessment framework for PM2.5 emissions, an international team of researchers from the US and Europe has characterized the primary PM2.5 intake fraction—the long-term population intake mass per unit mass emitted into different indoor and outdoor environments.

Intake fractions from residential and occupational indoor sources ranged from 470 ppm to 62,000 ppm—mainly as a function of air exchange rate and occupancy. Indoor exposure typically contributes 80−90% to overall exposure from outdoor sources. In a paper in the ACS journal Environmental Science & Technology, the researchers suggested that their framework facilitates improvements in air pollution reduction strategies and life cycle impact assessments.

ifo Institute study projects ban on combustion engines in 2030 would affect 600K jobs in German manufacturing

In Germany, legislation banning permits for new cars and light trucks with internal combustion engines as of 2030 is currently under consideration. A new study by the ifo Institute projects that such a ban could lead to significant losses in terms of jobs and added value in Germany. More than 600,000 jobs, or 10%, of jobs in German in manufacturing would currently be directly or indirectly affected by a ban. In the automotive industry alone a ban would endanger 436,000 jobs, while up to 130,000 jobs at small and medium-sized companies would be at risk.

Such a ban would also impact a total of 13% (amounting to around €48 billion) of gross value added. The study was commissioned by the German Association of the Automotive Industry (VDA).

EPA proposes maintaining current NOx standards

Based on its review of scientific evidence, the US Environmental Protection Agency (EPA) proposes retaining the current national ambient air quality standards (NAAQS) for oxides of nitrogen (NOx). EPA proposes that the current NAAQS don’t need to be changed because they provide the appropriate public health protection, with an adequate margin of safety, including for older adults, children and people with asthma.

There are currently two primary standards for NOx. NO2 is the component of oxides of nitrogen of greatest concern for health and is the indicator for the primary NAAQS. The two primary NO2 standards are: a 1-hour standard established in 2010 at a level of 100 parts per billion (ppb) and based on the 98th percentile of the annual distribution of daily maximum 1-hour NO2 concentrations, averaged over 3 years; and an annual standard, originally set in 1971, at a level of 53 ppb and based on annual average NO2 concentrations.
