Abstract:
1. Method for storing energy in gaseous form, the method comprising: a. providing a gas containment structure having an interior defined by a top, one or more sides, and a bottom; b. positioning the containment structure below a surface of a body of water, the structure being configured for water flow communication between the body of water and the structure interior at a location adjacent the structure bottom; c. selecting an energy-containing fluid from the group of gaseous energy-containing gases and liquefied energy-containing gases; d. providing a conduit for the energy-containing fluid to flow between a source of the energy-containing fluid proximate the surface of the water body and the structure interior adjacent the structure top; e. flowing the energy-containing fluid from the energy-containing fluid source through the conduit into the storage structure interior, the energy-containing fluid entering the storage structure being essentially in a gaseous phase; and f. displacing a volume of water from the containment structure interior substantially equivalent to the volume of the energy-containing fluid entering the structure interior.
