Abstract:
Systems and methods for storing energy in gaseous form in submerged thin-wailed tanks (1, 7, 61, 82, 63, 67, 101) are secured to the ocean or lake floor but are open to the water at the tank bottoms (1a, 64) and are configured to be filled with gas while submerged. A conduit (2, 2a, 11) operatively connected to the tanks (1, 7, 61, 62, 63, 67, 101) provides flow from a surface source of an energy-containing gas to the tank interiors (1d, 101 a). Surface or subsurface pumping apparatus (3, 37, 42, 46, 48, 53) which may include piston-less pressure cylinders (37) or have leveraged pistons (48, 53) provide a preselected flow rate of the energy-containing gas into the tank interiors (1d, 101 a) against a back pressure essentially equal to the static pressure of the body of water at the location of the tank (1, 7, 61, 62, 63, 67, 101) to displace an equivalent volume of water through the open bottom (1 a, 64). The conduit (2, 2a, 11) can be configured to allow heat transfer to vaporize liquefied gas prior to storage. Hydrogen gas can be generated and stored within the tank (1, 7, 61, 62, 63, 67, 101) using Aluminum activated with Galinstan.
Abstract:
A deep ocean gas storage system for storing compressed gas, the system comprising an inflexible thin walled storage vessel anchored to the sea floor having an axis located in water substantially perpendicular to and on a sea floor below sea level, a gas intake for admitting and discharging compressed natural gas to and from the vessel; a water port for admitting and discharging water to the vessel using hydrostatic pressure to discharge compressed gas from the vessel at a substantially constant discharge pressure as the volume of the gas in the storage vessel decreases when water content of the vessel increases; a conduit fluidly connected with the water port oriented substantially parallel to the axis having a discharge opening above the level of sea water in the vessel; and a valve disposed at the gas intake to the vessel for controlling compressed gas admission and discharge.
