“The plan calls for installation of solar and wind power facilities to provide clean renewable electrical power to the neighborhood but with a plus. Instead of storing any excess power in batteries, molten salt, or a pumped hydro facility, it will be used to produce hydrogen gas.
In theory, battery and molten salt storage is transitory. Hydrogen created using excess electricity can be stored for long periods of time and transported (using electric trucks, presumably) over long distances. One problem California has to deal with today is that it generates more renewable electricity than it can use at times. In some cases, utility companies in California pay utilities in other states to take the excess power off their hands.”
