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.

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. One of the catalytic conversion processes creates the high-octane gasoline blendstock.

Fraunhofer suggests e-scooters as application for its magnesium hydride paste hydrogen storage technology

Green Car Congress

Fraunhofer’s POWERPASTE releases hydrogen on contact with water. Specific energies and energy densities including conversion losses. Refueling would be simple; riders merely have to replace an empty cartridge with a new one and then refill a tank with water. It has a hydrogen capacity of about 10 mass-% (i.e. 10 kg POWERPASTE ?

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

Researcher urges more effort on assessment of land and water impacts of oil sands production; reference point for other unconventional fuels

Green Car Congress

Bitumen production from the Canadian oil sands provides a point of reference that could be used to observe and better manage the land and water impacts of a rapid transition to unconventional fuels, suggests Dr. Sarah Jordaan of the Energy Technology Innovation Policy Research Group, Department of Earth and Planetary Sciences, Harvard University.
