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%.

Scania launches new 13-liter natural gas engine

November 13, 2017

Scania, a member of the Volkswagen Group, has launched its new OC13 13-liter (swept volume 12.7 liters) natural gas engine, based on Scania’s well-proven inline 6-cylinder, 13-liter engine. The Euro 6 engine works according to the Otto principle with spark plugs and complete combustion and delivers 410 hp (302 kW) @ 1,900 rpm with 2,000 N·m torque @ 1,100–1,400 rpm—well in line with diesel engines of a similar size.

There is a growing interest in operating vehicles on biogas or natural gas in countries such as Italy and France as a result of increased availability, improved infrastructure and good economic viability for truckers. FPT Industrial also recently introduced its newest and most powerful natural engine, the 13-liter Cursor 13 Natural Gas, specially developed for long-haul missions. (Earlier post.)

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

November 05, 2017

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.

New plasma synthesis process for one-step conversion of CO2 and methane into higher value fuel and chemicals

October 09, 2017

Researchers from the University of Liverpool (UK), with colleagues from Dalian University of Technology (China) and the University of Hull (UK), have developed a new process for the direct, one-step activation of carbon dioxide and methane (dry reforming of methane) into higher value liquid fuels and chemicals (e.g., acetic acid, methanol, ethanol, and formaldehyde) with high selectivity at ambient conditions.

In a study published in chemistry journal Angewandte Chemie, they reported the total selectivity to oxygenates was approximately 50–60%, with acetic acid being the major component at 40.2% selectivity—the highest value reported for acetic acid thus far. The direct plasma synthesis of acetic acid from CH4 and CO2 is an ideal reaction with 100% atom economy, but is almost impossible by thermal catalysis owing to the significant thermodynamic barrier. The combination of plasma and catalyst in this process shows great potential for manipulating the distribution of liquid chemical products in a given process, they concluded.

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.

Audi’s bivalent 2.0 TFSI for the new A4 Avant and A5 Sportback g-trons

September 11, 2017

Audi extended its range of natural-gas-fueled g-tron models just a few weeks ago (earlier post) with the new A4 Avant g-tron and A5 Sportback g-tron. The A3 Sportback g-tron has been on the market since 2014.

The new A4 Avant g-tron and A5 Sportback g-tron are powered by a 2.0 TFSI engine operating according to the efficient, Audi-optimized B-cycle (Budack-cycle, earlier post) combustion principle. Whereas the traditional Miller cycle closes the intake valves just before the end of the intake stroke, the B-cycle closes the intake valves much earlier. This results in longer effective combustion as well as faster air flow for the incoming gases, which improves the mixing of the fuel and air.

Georgia Tech team furthers four-stroke-cycle active-membrane piston reactor for enhanced SMR for H2 production

February 17, 2017

Steam methane reforming is currently the primary pathway for hydrogen production worldwide. However, due to its high operating temperature and use of sequential units for the reaction stages, industrial SMR does not scale down well for distributed, point-of-use applications such as fuel cell vehicle refueling stations.

Seeking to develop an SMR system suited for such distributed applications, a team from Georgia Tech in 2014 proposed the sorption-enhanced CO2/H2 Active Membrane Piston reactor (CHAMP-SORB)—a variable-volume batch reactor for the production of hydrogen from catalytic steam reforming of methane that operates in a cycle similar to that of an internal combustion engine. Now, in a paper published in the ACS journal Industrial & Engineering Chemistry Research, the team has developed a comprehensive analysis of the system, focused on understanding the heat/mass transfer and reaction/separation interactions to develop guidelines for scale-up.

New CE-CERT report finds Cummins Wesport ISL G near-zero gas engine performs with lower NOx than EPA certification standard over range of cycles

February 02, 2017

A report released by the University of California Riverside’s College of Engineering-Center for Environmental Research and Technology (CE-CERT), found that the new 8.9L Cummins Westport ISL G near-zero (NZ) natural gas engine (earlier post) meets and exceeds the certification standards during a full range of duty cycles. This finding is in stark contrast to previously released CE-CERT data and a recently released report by the California Air Resources Board that found heavy-duty diesel trucks emitted higher levels of NOx than their certification standards in the same duty cycles.

With the near-zero emission factors demonstrated for natural gas vehicles, it is expected that these vehicles could play an important role in providing much needed emissions reductions required for the South Coast Air Basin and California to reach federal air quality attainment standards.

BP Energy Outlook: 30% growth in global demand to 2035; fuel demand continues to rise, even with EVs & fuel efficiency

January 25, 2017

The 2017 edition of the BP Energy Outlook, published today, forecasts that global demand for energy will increase by around 30% between 2015 and 2035, an average growth of 1.3% per year. However, this growth in energy demand is significantly lower than the 3.4% per year rise expected in global GDP, reflecting improved energy efficiency driven by technology improvements and environmental concerns. The Outlook looks at long-term energy trends and develops projections for world energy markets over the next two decades.

While non-fossil fuels are expected to account for half of the growth in energy supplies over the next 20 years, the Outlook projects that oil and gas, together with coal, will remain the main source of energy powering the world economy, accounting for more than 75% of total energy supply in 2035, compared with 86% in 2015.

ExxonMobil develops efficient new technology to dehydrate natural gas; exclusive license to Sulzer

January 05, 2017

ExxonMobil has developed new technology for natural gas dehydration that employs a patented absorption system inside pipes and replaces the need for conventional dehydration tower technology. The “in-line” cMIST (Compact Mass transfer and Inline Separation Technology) could be deployed at both land-based and offshore natural gas production operations and represents a step-change in efficiency and a concomitant significant reduction in operational footprint.

The new technology, developed and extensively field-tested by ExxonMobil, more efficiently removes water vapor present during the production of natural gas. Removing water vapor through the use of dehydration technology, typically accomplished using large and expensive dehydration towers, reduces corrosion and equipment interference helping to ensure the safe and efficient transport of natural gas through the supply infrastructure and ultimately to consumers.

Cummins Westport ISB6.7 G midrange natural gas engine now in full production

December 09, 2016

Cummins Westport’s ISB6.7 G, a 6.7 liter midrange, factory-built natural gas engine is now fully available as a production engine for shuttle bus, medium duty truck, and vocational applications in North America. (Earlier post.) As previously announced, the engine has been available for school bus applications since May 2016 from Thomas Built Buses. The 6.7 liter engine platform has large OEM availability for midrange trucks, vocational trucks and mid size buses and the expansion of applications potentially available for the ISB6.7 G engine more than doubles its addressable market.

The ISB6.7 G is based on the Cummins ISB6.7 diesel engine platform, the industry leader in the Cummins midrange engine family, and operates exclusively on natural gas, including compressed, liquid, or renewable natural gas (RNG). The ISB6.7 G is the second engine from Cummins Westport (CWI) to receive emission certification from the US Environmental Protection Agency (EPA) and the Air Resources Board (ARB) in California for meeting the Optional Low NOx Emissions standards.

Eco-Motive reveals prototype H-Motor dual fuel engine; road testing to begin soon

December 02, 2016

Eco-Motive, a startup developing what it calls the first dual-fuel “H” engine (earlier post), revealed photos of a full-scale prototype of the Eco-Motive H-Motor. The prototype was completed in February 2016 and was built to reflect the engine configuration when installed in a vehicle; testing in driving applications will begin soon.

The H-shaped engine has parallel left-side and right-side vertical inline piston banks, each with a crankshaft and pistons, cylinder head, and individual fuel feeds, but sharing a common power transmission system. The H-motor—essentially two separate engines housed within the same engine block—can be powered by either gasoline or compressed natural gas (CNG), at the driver’s decision.
