Abstract
Technologies are described herein for storing fluid in an underwater cryogenic storage vessel designed for use in a fuel system of an underwater vehicle. According to one aspect of the disclosure, a storage vessel includes at least two concentrically arranged storage tanks, which includes a first storage tank and a second storage tank. The first storage tank surrounds the second storage tank, such that the first storage tank is configured to protect the second storage tank from external environmental conditions. The storage vessel also includes a storage compartment positioned adjacent to the two storage tanks. In one embodiment, the storage vessel may be an underwater cryogenic storage vessel that stores liquid oxygen used as a reactant in a fuel cell and liquid carbon dioxide, which is an effluent of the fuel cell.
