Abstract
A system and method utilizing compressed gas according to which the gas is compressed at a location above ground and transported to an underwater location. The gas is stored at the underwater location and later returned from the underwater location to the above-ground location for utilization as energy.
Claims22
A system for utilizing compressed gas, the system comprising a source of the compressed gas located on land, a storage vessel having an axis located substantially horizontally on a sea floor below sea level, a piping system connecting the source and the vessel so that the compressed gas can be transferred from the source to the vessel for storage, the storage vessel being flexible so that the hydrostatic pressure acting on the vessel can cause the compressed gas to discharge from the vessel at a substantially constant discharge pressure as the volume of the gas in the storage vessel decreases.
A method comprising compressing gas at a compressor located above ground, transporting the compressed gas to a flexible storage vessel located substantially horizontally below sea level, storing the gas in the storage vessel, utilizing hydrostatic pressure to discharge the compressed gas from the storage vessel, and returning the compressed gas to a ground location at a substantially constant discharge pressure as the volume of the gas in the storage vessel decreases.
