3 winners of DOE’s “America’s Next Top Energy Innovator” Challenge: hydrogen-assisted lean-burn engines, graphene for Li-air and -sulfur batteries, and titanium process

Green Car Congress

One negative side effect of a lean burn engine, whether powered by gasoline or diesel fuel, is an increase in the amount of emissions released to the environment. The plasma reformer, installed into the engine compartment, convert fuel into hydrogen.

Probing the effect of CO2 on Li-air batteries

Green Car Congress

Lithium-air batteries, with a theoretical gravimetric energy density of ?3500 The difference in chemical stability implies that there is always a thermodynamic driving force to convert Li 2 O 2 , the desired discharge product of a Li?air air cell, into Li 2 CO 3 in the presence of CO 2. —Lim et al. —Lim et al.

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

Today’s technologies for making biofuels all rely on photosynthesis—either indirectly by converting plants to fuels or directly by harnessing photosynthetic organisms such as algae. This process is less than 1% efficient at converting sunlight to stored chemical energy. NC State University. Engineering E. of Georgia).
