MIT team outlines path to low-cost solar-to-fuels devices; the artificial leaf

Green Car Congress

A team of researchers at MIT has described a framework for efficiently coupling the power output of a series-connected string of single-band-gap solar cells to an electrochemical process that produces storable fuels. This paper performs an equivalent circuit analysis for multiple series-connected devices. Source: Winkler et al.

Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. Sodium is an abundant low-cost metal, and a main ingredient in seawater.

ARPA-E announces $98M in funding for 40 OPEN projects; two opposed-piston engines projects receive $10M total

Green Car Congress

Of those selected, approximately 43% of OPEN 2018 projects will be led by universities, 35% by small businesses, and the remainder by large businesses, non-profit organizations or federally funded research and development centers (FFRDCs). This technology would be simple, cost effective, and well-suited to large-scale processing.
