In 2001, a team of engineers at a then-obscure R&D company called AC Propulsion quietly began a groundbreaking experiment. They wanted to see whether an electric vehicle could feed electricity back to the grid. The company’s president, Tom Gage , dubbed the system “vehicle to grid” or V2G.

NY-BEST is an industry-focused coalition working to establish New York as a global leader in energy storage technology for heavy-duty transportation, electric grid and other storage applications. These could replace conventional lead-acid batteries, which work poorly in cold temperatures. Earlier post.) Graphene Devices Ltd.

The technology is unique because it can function in a variety of extreme conditions and store as much energy as lead-acid batteries twice its size while lasting up to 10 times as long. When the generator is off and the battery is fully charged, it feeds the stored power back to the cell tower.

Hurst also notes that the market for hybrid locomotives faces stiff competition from newer fuel-efficient locomotives such as diesel gensets, and in many world regions, the locomotive engine does not have to meet strict emissions rules. Other benefits include reduced noise levels and lower maintenance costs.

Engineering surface area, pore size distribution, and total pore volume can deliver carbon material with a broad range of surface properties. The [nano-structured hard] carbon is able to store more than standard graphite (which is what the 50% is based on) because it has a disorganized amorphous structure. Aaron Feaver.
