ABSTRACT:
An energy storage system has a first pressurized tank for carrying water and hydrogen gas and a second pressurized tank for carrying water and oxygen gas. A first output line connects to the pressurized tank for carrying hydrogen gas from the tank. A second output line connects to the second pressurized tank for carrying oxygen gas from the second tank. The energy storage system has a differential-pressure relief valve connected to the output lines to maintain the gases within a defined pressure differential. A water line connects to both pressurized tanks for maintaining relative water levels in the tanks. An electrolyzer is maintained under pressure and receives water from at least one of the pressurized tanks and creates hydrogen gas and oxygen gas for storage in the pressurized tanks. An accumulator connects to the output lines and having a movable diaphragm that separates the gases and moves to adjust volume to equalize pressure. A regeneration system having the energy storage system and a fuel cell for generating electrical energy is connected to the output lines. A catalyst hood overlies the electrolyzer. In a preferred embodiment of the regeneration system, both the electrolyzer and the fuel cell have a proton exchange membrane. A solar array is connected to the electrolyzer in the regeneration system.
