Geologic Energy Storage

The United States (U.S.) domestic energy supply increasingly relies on natural gas and renewable sources; however, their efficient use is limited by supply and demand constraints. For example, a) in summer, natural gas production may outpace home heating fuel demand and b) in daytime, wind and solar electricity production may outpace industrial power requirements. Storing rather than dumping...
