NREL-led team overcomes major technical obstacle in Mg-metal batteries by developing artificial solid-electrolyte interphase

Green Car Congress

Magnesium offers a number of advantages over lithium for rechargeable batteries: it is safer and earth-abundant, and doubles the total charge per ion, delivering larger theoretical volumetric capacity compared with a typical lithium-ion battery. Further, in Mg batteries (MB) the anode is energy-dense Mg metal (~?3,830 —Son et al.

Laser-burned graphene could replace platinum as fuel cell catalyst

Green Car Congress

Graphene is a unique material that has been widely investigated and found to have broad applications in fields such as energy storage, electronics, and electrocatalysis. Further doping of the material with sulfur allowed for hydrogen evolution, another catalytic process that converts water into hydrogen. —James Tour.

US DOT Awards $100M in Recovery Act Funds to 43 Transit Projects to Reduce Energy Consumption and Greenhouse Gas Emissions

Green Car Congress

The project includes quick-charging stations at this terminal layover in route to recharge bus batteries. Grid sourced electrical energy used to recharge the bus batteries will be augmented with solar energy collected with panels procured and installed under this project. Maryland Transit Administration, Maryland: $522,000.
