A leak containment storage facility includes a containment vessel with an inner tank surrounded by an outer tank. Upon detection of a leak in the inner tank, the pressure within the outer tank can be increased, usually by flooding the tank, to contain the leak. This facility has special application in a deep basing environment in which a personnel area is powered by hydrogen/chlorine fuel cells. The chlorine is stored as a liquid in the inner tank. Stored water in a reservoir floods the outer tank to apply a pressure on chlorine that leaks from the inner tank and keeps the chlorine from evaporating. Generally the pressure is achieved by the hydrostatic head alone and pumps or compressors are not use.
