California Hydrogen Business Council says a robust P2G RD&D program should be a priority for the state

Green Car Congress

The case for using Power-to-Gas solutions to store renewable energy is compelling for a number of important use cases, according to a new white paper released by the California Hydrogen Business Council (CHBC). Power-to-Gas energy storage leverages an already existing storage infrastructure that has a vast amount of capacity—i.e.,

Study Finds PHEV Li-ion Cells Show Little Capacity Fade Under Combined Driving and V2G Usage; Economic Model Suggests Incentives Will Be Required for Vehicle Owners to Participate in V2G

Green Car Congress

A new draft working paper published by the Carnegie Mellon Electricity Industry Center concluded that a PHEV pack comprising lithium iron phosphate cells would incur little capacity loss from combining vehicle-to-grid (V2G) activities with regular driving. Test current profile used to simulate driving day for cells showing all trips.
