Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

As the percentage of electricity supply from wind and solar increases, grid operators will need to employ strategies and technologies, including energy storage, to balance supply with demand given the intermittency of the renewable supply. Coal- and natural gas-fired power plants are responsible for at least a third of those emissions.

US DOE Issues Request for Information on Hydrogen and Fuel Cell Market Development; Reports to Congress on Program

Green Car Congress

Hydrogen produced by water electrolysis has the potential to be a useful means of storing excess electricity generated using wind, solar, and other intermittent renewable energy. Biogas, including anaerobic digester gas, can be reformed to produce hydrogen and used in a fuel cell to produce significant amounts of electricity and heat.

Electric Scooter vs Petrol Scooter : Huge benefits for India

Plug In India

Many of you write to us about the long tailpipe of electric vehicles and coal is major source of electricity generated in India. Studies from independent scientists tell us that even if 100% of Electricity is generated from coal, EV’s emit 50% lesser carbon gases due to the efficiency of the electric motor.
