Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Now, a study by researchers at the US Department of Energy (DOE) Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has found that energy sorghum ( Sorghum bicolor ) behaves more like miscanthus in the way it efficiently captures light and uses water to produce abundant biomass.

Study finds perennial biofuel crops’ water consumption similar to corn

Green Car Congress

A study by a team from the Great Lakes Bioenergy Research Center (GLBRC) has found that perennial biofuel crops’ evapotranspiration does not differ greatly from corn. Growing such crops on marginal lands could avoid competition with food, indirect land use change effects, and local carbon debt. —Hamilton et al.

Honda to advance fuel cell system as core of its hydrogen business; expansion to other areas; new FCEV in 2024

Green Car Congress

With the next-generation fuel cell system being co-developed with General Motors (GM), Honda will aim to more than double the durability and reduce the cost to one-third, in comparison to the fuel cell system installed in the 2019 Honda Clarity Fuel Cell. Initiatives toward the establishment of hydrogen ecosystems.

U Delaware team demonstrates efficient direct ammonia fuel cell for vehicles

Green Car Congress

The researchers started by analyzing the economics of hydrogen-, nitrogen-, and carbon-based fuels made by carbon-neutral pathways in a post-fossil world in which only water, air, and renewable electricity are available for fuel synthesis. Source-to-tank cost comparison of carbon-neutral transportation fuels.

LBNL, Nissan researchers explore ethanol internal reforming in SOFCs for vehicle applications

Green Car Congress

The e-Bio Fuel Cell system featured an an SOFC stack and an on-board reformer to convert 100% ethanol or ethanol-blended water (55% water, 45% ethanol) to hydrogen. Dilution of ethanol with water increases safety, and is expected to suppress anode coking by increasing the steam-to-carbon ratio. … Earlier post.)

SwRI CAT-DEF reduces heavy-duty diesel emissions to meet CARB 2027 NOx requirements

Green Car Congress

urea-water solution—is injected into the exhaust stream and ideally decomposes to form ammonia, which reacts with NO x on the SCR catalyst to form N 2 and H 2 O. SwRI’s novel technology decreases NO x and carbon dioxide emissions for diesel engines by significantly reducing undesirable deposit formation in exhaust systems.
