DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

estimated that with conversion by hydrothermal liquefaction (HTL) and upgrading, the wet waste resource availability in the United States could be converted to jet fuel that is equivalent to about 24% of the U.S. Skaggs et al. demand in 2016. 1c06561.

NREL develops novel method to produce renewable acrylonitrile; carbon fibers from renewable biomass

Green Car Congress

Researchers from the National Renewable Energy Laboratory (NREL) and their colleagues have devised a novel catalytic method to produce renewable acrylonitrile (ACN) using 3-hydroxypropionic acid (3-HP), which can be biologically produced from sugars. Conceptual process diagram for renewable ACN production from biomass sugars.

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.

Electra raises $85M to advance Low-Temperature Iron process; electrochemical refining at 60?C

Green Car Congress

By comparison, 69% of steel today is made at approximately 1,600 degrees Celsius (2,912 degrees Fahrenheit) using coal, emitting about two tons of carbon dioxide for every ton of steel produced. Conversion of iron ore into iron accounts for 90% of steelmaking emissions that may be eliminated using Electra’s process.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. In comparison, the energy density for lithium-ion batteries used in commercial electronics and electric vehicles is around 170–250 Wh/kg.
