New version of Argonne lifecycle model for water footprint of biofuels now includes cellulosic feedstocks

Green Car Congress

of the online tool Water Assessment for Transportation Energy Resources ( WATER ) this week. This latest version of WATER allows, for the first time, biofuels manufacturers to analyze water consumption associated with use of cellulosic feedstocks such as residue left from lumber production and other wood-based resources.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle. Supercritical carbon dioxide is a non-toxic, stable material that is under so much pressure it acts like both a liquid and a gas. Graphic courtesy Sandia National Laboratories).

USDA provides $91M loan guarantee to Cool Planet for biogasoline blendstock plant; biomass pyrolysis and catalytic conversion

Green Car Congress

Gas chromatography comparison of Conoco fuel and a Conoco-CoolPlanet blend. Cool Planet has devised a biomass-to-liquids thermochemical conversion process that simultaneously produces liquid fuels and sequesterable biochar useful as a soil amendment. Cool Planet’s biogasoline blendstock is 100% compatible with pump gasoline.

Study finds perennial biofuel crops’ water consumption similar to corn

Green Car Congress

Evapotranspiration (ET) refers to the sum total of water lost while the plant is growing, either from evaporation through the plant stem itself (a process called “transpiration”), or from water evaporated off of the plant’s leaves or the ground. —Hamilton et al.

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

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. These deposits severely limit low-temperature NO x conversion and increase fuel consumption as high-temperature engine operations are required to remove the deposits.
