Argonne white paper outlines battery and R&D requirements for electric aviation

Green Car Congress

The paper explores four aircraft concepts: air taxis; 20-passenger commuter aircrafts; 50-passenger regional jets; and 150-passenger, single-aisle 737-class aircraft. For each concept, the paper describes a research area where DOE and NASA could help spur innovation in electric aviation batteries.

DOE to award $33M to advance hydrogen and fuel cell R&D and the H2@Scale vision

Green Car Congress

H2NEW includes National Renewable Energy Laboratory and Idaho National Laboratory as co-leads, and focuses on R&D to enable affordable, durable and efficient large-scale electrolyzers, which produce hydrogen from electricity and water (at both high and low temperatures). This would be coordinated with the H2NEW consortium.
