Embodiments provide systems and methods for taking power from an electric power grid and converting it into higher-pressure natural gas for temporary storage. After temporary storage, the higher-pressure natural gas may be expanded through an expansion engine to drive a generator that converts energy from the expanding natural gas into electrical power, which may then be returned to the electric power grid. In this way, the disclosed systems and methods may provide ways to temporarily store, and then return stored power from the electric power grid. Pref...
1. A system at a natural gas storage facility, the system comprising: natural gas received from a natural gas pipeline system;a compressor configured to receive the natural gas and to compress the natural gas from a pipeline pressure to a reservoir pressure to form high-pressure natural gas and waste heat of compression;a controllable reservoir configured to receive the high-pressure natural gas from the compressor, temporarily store the high-pressure natural gas, and release the high-pressure natural gas after storage;an expansion engine configured to r...
