CMU study compares lifecycle GHGs of natural gas pathways for MHDVs; MD BEVs can deliver large reductions, but diesel hard to beat for Class 8

May 27, 2015

A study by Carnegie Mellon University researchers comparing life cycle greenhouse gas (GHG) emissions from different natural gas pathways for medium and heavy-duty vehicles (MHDVs) found that the GHG reduction potentials of the pathways vary sharply between non-Class 8 MHDVs (e.g., pick-up trucks, parcel delivery trucks, and box trucks), Class 8 transit buses, and Class 8 MHDVs (e.g., refuse trucks and tractor-trailers).

Battery-electric (BEVs), LPG, and CNG pathways could reduce life cycle GHG emissions for non-Class 8 MHDVs compared to the baseline petroleum fuels. Similarly, BEVs achieve emission reductions for transit buses. On the other hand, none of natural gas pathways, CNG, LNG, and F-T liquids, achieve any emission reductions per unit of freight-distance moved for Class 8 trucks compared to conventional diesel. The study is published in the ACS journal Environmental Science & Technology.

Lifecycle study finds fuel switching from diesel to natural gas could produce net climate damage absent reductions in CH4 emissions and improved vehicle efficiency

May 20, 2015

A study by a team from the Environmental Defense Fund, in collaboration with a colleague from the Lenfest Center for Sustainable Energy at Columbia University has found that while switching a heavy-duty truck fleet from diesel to natural gas has the potential to produce climate benefits, realizing that potential would require a combination of significant reductions well-to-wheels methane emissions (i.e., addressing leakage) and efficiency improvements in the natural gas vehicles themselves. Otherwise, fuel switching can produce net climate damages (more radiative forcing) for decades.

The results, published in an open access paper in the ACS journal Environmental Science & Technology, suggest that policymakers wishing to address climate change should use caution before promoting fuel switching to natural gas, the authors concluded.

First integrated assessment of quality and yield of hydrocarbon blendstocks via biomass fast pyrolysis and hydrotreating

April 27, 2015

Researchers from three US national labs—Pacific Northwest National Laboratory (PNNL), Idaho National Laboratory (INL) and the National Renewable Energy Laboratory (NREL)—have performed the first, fully integrated assessment of the quality and yield of common feedstocks from the field to hydrocarbon blendstock production using the fast pyrolysis-hydrotreating pathway. A paper describing the results is published in the ACS journal Energy & Fuels.

Among their findings was that the compositional parameters of the biomass feedstock affects both the bio-oil generated by fast pyrolysis as well as the final quantity and quality of the upgraded fuel blendstock. While some feedstocks—such as tulip poplar—generate a high yield of bio-oil, the bio-oil does not necessarily exhibit a high yield in the hydrotreater. Thus, the product yields and qualities of both fast pyrolysis and hydrotreating must be considered in comparing the conversion performance of different biofuel feedstock materials.

Achates Power testing shows transient capabilities of opposed piston engine

Initial test results of the transient control and exhaust temperature management capability of Achates Power’s opposed piston (OP) two-stroke diesel engine show that under a typical transient maneuver—25% to 100% load step at low and constant engine speed—the engine can control both NOx and soot with a minimal torque lag. Test results also showed that the air system control flexibility and robust combustion system that Achates Power developed for the OP engine can be used to achieve high exhaust gas temperatures for a diesel engine at idle-like speeds and load, thereby assisting catalyst light-off.

The results follow a paper published earlier this year detailing steady-state testing results that showed the research 4.9L three-cylinder engine was able to achieve 43% brake thermal efficiency at the best point and almost 42% on average over the modes of the SET (Supplemental Emission Test) cycle. The results from this test confirmed the modeling predictions and pointed to a 48% best BTE and 46.6% average over the cycle for a production design of this engine, the Achates team concluded. With the latest paper Achates Power is exploring other critical attributes necessary to deliver a successful engine to the industry.

Equipped with the new EA288 2.0L TDI diesel, the SportWagen can offer up to 43 mpg (5.47 l/100 km) on the highway—matching the fuel economy rating of the 2015 BMW 328d xDrive Sports Wagon, currently the highway fuel economy leader among the wagon segment, according to fueleconomy.gov.

VW of America is hosting a media drive in a rainy Austin, Texas this week to introduce the new model. (Earlier post.) Although currently only offered with FWD (an AWD version is slated for next year, according to Volkswagen), the Golf SportWagen stayed glued to the rain-slick roads in the hills around Austin even through climbing and dipping curves at speeds well exceeding posted limits. The lower profile and center of gravity compared to an SUV, combined with the powertrain, suspension and chassis, give the SportWagen a nimble and secure feel even in nasty weather.

Navy researchers produce 100% bio-derived high-density renewable diesel and jet by blending sesquiterpanes with synthetic paraffinic kerosene

March 06, 2015

A team at the Naval Air Warfare Center Weapons Division (NAWCWD) at China Lake has produced 100% bio-derived high-density renewable diesel and jet fuels by blending multicyclic sesquiterpanes with a synthetic paraffinic kerosene (5-methylundecane). The resulting renewable fuels have densities and net heats of combustion higher than petroleum-based fuels while maintaining cetane numbers high enough (between 45 and 57) for use in conventional diesel engines.

The team said that its results show that full-performance and even ultra-performance fuels can be generated by combining bio-derived sesquiterpanes and paraffins. All components can be generated from biomass sugars by a combination of fermentation and chemical catalysis which may allow for their production at industrially relevant scale, they noted. An open access paper on the work has been accepted for publication in the ACS journal Energy & Fuels.

Neste Oil now the world’s largest producer of renewable fuels from waste and residues

March 05, 2015

Over the last few years, Neste Oil has become the world’s largest producer of renewable fuels from waste and residues. In 2014, the company produced nearly 1.3 million tonnes (1.6 billion liters, 423 million gallons US) of renewable fuel from waste and residues. In practical terms, this is enough to power for two years all the 650,000 diesel-powered passenger cars in Finland with NEXBTL renewable diesel manufactured from waste and residues.

Examples of Neste Oil’s waste and residue-based raw materials include animal and fish fats; used cooking oil; and various residues generated during vegetable oil refining such as palm fatty acid distillate (PFAD) and technical corn oil. These raw materials accounted for 62% of Neste Oil’s renewable inputs in 2014 (52% in 2013, 35% in 2012).

Study: natural gas heavy-duty trucking fleet could benefit economy, but has mixed environmental effects

February 20, 2015

Switching from diesel fuel to natural gas may hold advantages for the US heavy-duty trucking fleet, but more needs to be done to reach the full environmental benefits, according to a new white paper released by the Institute of Transportation Studies at the University of California, Davis, and Rice University.

The recent shale-driven emergence of natural gas as an abundant, inexpensive fuel in the US has raised the possibility of a “momentous shift” in the level of natural gas used in transportation. The cost advantage of natural gas over diesel fuel is particularly appealing for vehicles with a high intensity of travel and thus fuel use. In the paper, the team investigated the possibility that natural gas could be utilized to provide fuel cost savings, geographic supply diversity and environmental benefits for the heavy-duty trucking sector—and whether it can enable a transition to lower carbon transport fuels.

ICCT reviews real-world tractor-trailer fuel economy in US, China and Europe

February 15, 2015

The International Council on Clean Transportation (ICCT) has published a new paper reviewing and summarizing data on commercial vehicle sales and real-world fuel consumption for heavy-duty tractor-trailers in the three key markets of the US, China and Europe, which together account for more than 70% of HDV sales worldwide.

The review found that in the US, average tractor-trailer fuel consumption rates for the entire fleet are approximately 39 L/100 km (6 mpg). For the newest US models, fuel consumption is typically between 33 and 36 L/100 km (6.5–7 mpg). A fleet-wide analysis done for the European Commission estimates tractor-trailer fuel consumption at roughly 31 L/100 km (7.6 mpg), while tests of individual vehicles done by trucking magazines suggest somewhat higher average rates of consumption at approximately 36 to 38 L/100 km (6.5 to 6.2 mpg). Chassis dynamometer testing performed as part of the regulatory development process in China reveals that tractor-trailers seem to have much higher fuel consumption rates, on average, than in the US and the EU, with laboratory results yielding an average of 44 L/100 km (5.4 mpg).

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

January 27, 2015

The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. The Advanced Collaborative Emissions Study (ACES), released today by the Health Effects Institute (HEI), also confirmed that the concentrations of particulate matter and toxic air pollutants emitted from NTDE are more than 90% lower than emissions from traditional older diesel engines (TDE). (Earlier post.) HEI is an independent, non-profit research institute funded jointly by the US Environmental Protection Agency (EPA) and the worldwide motor vehicle industry.

The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology. The study evaluated the long-term effects of multiple concentrations of inhaled NTDE in male and female rats on more than 100 different biologic endpoints, including tumor development, and compared the results with biologic effects seen in earlier studies in rats after exposure to TDE.

UBC study associates exposure to diesel exhaust with changes in DNA methylation

January 09, 2015

As an organism lives and grows, chemical reactions activate and deactivate parts of its genome at strategic times and in specific location. (Epigenetics is the study of these reactions.) DNA methylation—a chemical process in which a methyl group is added to cytosine primarily in the context of a cytosine-guanine dinucleotide (CpG)—is one of several epigenetic mechanisms that cells use to control gene expression.

While changes in DNA methylation have been associated with traffic-related air pollution in observational studies, the specific mechanisms have not been explored in a controlled study of asthmatics. In an open access study published in the journal Particle and Fibre Toxicology, a team from the University of British Columbia investigated the short-term effects of diesel exhaust inhalation on DNA methylation levels at CpG sites across the genome in circulating blood in asthmatics.

Advanced furoate esters biofuel company xF Technologies appoints Tom Stephens to board

January 07, 2015

xF Technologies Inc., developer of a family of low cost, renewable furoate esters (xF) for use as oxygenating blend components (5%-20%) in both gasoline and diesel fuels, as well as heating oil and other specialty applications, has appointed former GM Vice Chairman and Chief Technology Officer Tom Stephens as an independent director of the Company, effective immediately. (xF calls its family of molecules “408”—a phonetic play on furoate.)

xF’s continuous production technology uses common materials (steel and plastic) at moderate operating conditions to convert a biomass feedstock into a chemical intermediate that is subsequently combined with an alcohol to form the furoate ester product. The technology allows the production of numerous products depending on the type of or mixture of alcohols. These products exhibit fuel properties similar to each other and are named for the primary alcohol used in their production. For the four smallest chain alcohols, the resultant products are called Methyl 408, Ethyl 408, Isopropyl 408 and Butyl 408.

Drive cycle fuel economy for PFI, CDC, and multi-mode RCCI operation. Credit: Curran et al. Click to enlarge.

A team at Oak Ridge National Laboratory (ORNL) has added to the growing body of work exploring the applications and benefits of reactivity-controlled compression ignition (RCCI) by simulating the fuel economy and emissions for a multi-mode RCCI–enabled vehicle operating over a variety of US drive cycles using experimental engine maps for multi-mode RCCI; conventional diesel combustion; and a 2009 port-fuel injected gasoline engine. Their paper is published in the International Journal of Engine Research.

Among their findings were that multi-mode RCCI has the potential to offer greater than 15% fuel economy improvement over a 2009 gasoline PFI baseline over many light-duty driving cycles, despite the lack of complete drive cycle coverage for RCCI mode. Fuel usage over the drive cycles showed that nearly equal amounts of gasoline and diesel fuel would most likely need to be carried on board for RCCI multi-mode operation, which requires two fuels. During RCCI-only operation, fuel usage was found to be between 57 and 69% gasoline.

Boeing conducts world’s first flight with 15% blend of NExBTL renewable diesel as aviation biofuel

December 04, 2014

Boeing has completed the world’s first flight using “green diesel,” a renewable, drop-in hydrocarbon biofuel that is widely available and used in ground transportation. The company powered its ecoDemonstrator 787 flight test airplane with a blend of 15% NExBTL renewable diesel from Neste Oil and 85% petroleum jet fuel in the left engine. (Neste Oil can also produce a NExBTL synthetic paraffinic kerosene as a discrete, and already approved, commercial aviation fuel.)

Boeing previously found that renewable diesel is chemically similar to HEFA (hydro-processed esters and fatty acids) aviation biofuel approved in 2011. With a renewable diesel production capacity of 800 million gallons (3 billion liters) in the US, Europe and Asia, the on-road fuel could rapidly supply as much as 1% of global jet fuel demand. With a wholesale cost of about $3 per gallon, inclusive of US government incentives, green diesel approaches price parity with petroleum jet fuel.

Tsinghua team devises in-cycle control method for diesel LTC using detection of Start of Combustion

November 25, 2014

Low temperature combustion (LTC) refers to a broad range of in-cylinder combustion strategies for the reduction of NOx emissions from diesel combustion; NOx is formed primarily by a thermal mechanism, which production rates increasing exponentially with temperature. LTC strategies reduce combustion temperatures by the dilution of the in-cylinder combustible mixtures, either with excess charge gas to create more fuel-lean mixtures, or with moderate to high levels of EGR.

However, challenges remain in diesel low temperature combustion implementation due to combustion inconsistency or instability. To address this, a team from Tsinghua University has devised an in-cycle combustion feedback control method based on the detection of the Start of Combustion (SOC) in diesel LTC. A paper describing their method is published in the journal Applied Energy.

Ensyn begins generation & sale of cellulosic biofuel RINs under RFS2

November 09, 2014

Ensyn has initiated the generation and sale of its first RINs (Renewable Identification Numbers) under the US Renewable Fuel Standard (RFS2) (earlier post); Ensyn’s D7 cellulosic RINs have received QAP certification. Ensyn is the first company to generate cellulosic RINs under the US Environmental Protection Agency’s expanded definition of Heating Oil under RFS2, which became effective in December 2013. Ensyn believes it is now the leading producer of cellulosic D7 RINs in 2014.

D7 RINs are generated by Ensyn by displacing petroleum heating fuels (including #6, #4 or #2 diesel fuel oil) in customers’ boilers with Ensyn’s RFO (Renewable Fuel Oil) produced via Ensyn’s RTP (Rapid Thermal Processing) fast pyrolysis technology. (Earlier post.) RFO is a cellulosic biofuel produced from non-food solid biomass including forest residues. RFO is used to displace petroleum fuels in heating operations and is also a renewable feedstock for conventional petroleum refineries for the production of gasoline and diesel.

Neste Oil seeking California LCFS approval for gutter oil to renewable diesel pathway

October 26, 2014

Among four new California Low Carbon Fuel Standard (LCFS) fuel pathway applications is a used cooking oil (gutter oil) to renewable diesel (NExBTL) pathway from Neste Oil at its Singapore plant. (Boeing and COMAC are opening a demonstration facility in China to convert gutter oil to renewable aviation fuel. Earlier post.)

Neste Oil Singapore Pte Ltd. produces approximately 250 million gallons annually of drop-in renewable diesel (RD)—i.e., not biodiesel—using a hydrogenation process and multiple oil and fat feedstocks. Neste has also filed applications for renewable diesel pathways for California (all from its Singapore plant) using Southeast Asian rendered fish oil (earlier post); New Zealand tallow (earlier post); North American tallow (earlier post), and Australian tallow (earlier post). Of the five RD pathways proposed so far, the gutter oil pathway has the lowest carbon intensity.

Results of a modeling study by researchers from the US Environmental Protection Agency (EPA) suggest that widespread use of nanoparticulate cerium (nCe) diesel fuel additives across the US would have a measurable effect on regional air quality.

The model calculations suggest modest decreases of average PM2.5 concentrations and relatively larger decreases in particulate elemental carbon (EC). On average, across the 14-day winter and summer periods modeled, the percent change in EC exceeds that of PM2.5 by a factor of 5 in urban areas. As EC is a short-lived climate forcer, the reduction in EC concentrations has potential policy implications.

ICCT study finds real-world NOx emissions from Euro 6 diesels ~7x higher than Euro 6 regulatory levels

October 12, 2014

On-road NOxemission levels of Euro 6 diesel cars in Europe are on average about seven times higher than the NOx limit set by the Euro 6 emission standard, according to a new report published in Berlin by the International Council on Clean Transportation (ICCT). The study follows another recent ICCT report showing that the gap between official and real-world fuel-economy figures in Europe has risen to about 38%. (Earlier post.)

The latest study—the most comprehensive report on the real-world behavior of the latest generation of diesel cars published to date—found “remarkable” differences among individual vehicle models, indicating that technologies for real-world clean diesels already exist but are not being employed consistently by different vehicle manufacturers.

Chevy’s Cruze Diesel: a compact diesel contender in the US

September 08, 2014

2014-Chevrolet-Cruze-TD-031
The Cruze Diesel is identified by a discreet badge on the trunk. Click to enlarge.

US buyers hunting for a non-premium diesel passenger car (i.e., not a truck or SUV, and not a vehicle from BMW, Audi, Porsche or Mercedes-Benz) have until recently only had Volkswagen-brand cars as an option: Beetle, Golf, Jetta, Passat. Accordingly, Volkswagen of America (VoA) diesel sales to date in 2014 represent slightly north of 23% of all Volkswagen of America sales. In August, Jetta posted 3,988 diesels sales (26% of Jetta sales, while Passat TDI sales were 2,767 units, representing 30.1% of sales of the vehicle.

However, Chevrolet is trying to challenge that passenger car diesel hegemony with the compact Cruze Diesel, introduced for MY 2014, and now with a facelift for MY 2015. (Earlier post.) Chevrolet is positioning the Cruze, which features a US-modified 2.0L diesel from GM’s European lineup (the engine is manufactured in Kaiserslautern, Germany) to challenge Jetta on the basis of highway fuel economy and power, as well as content. Based on a week with the car (MY2014), the claimed fuel economy superiority may be tough to realize in real-world driving (especially in the face of the new, more fuel-efficient diesel in the 2015 Jetta, earlier post) but overall, the Cruze Diesel is a worthy challenger, and a very good and thrifty drive, especially on the highway.
