    Abstract: The cryogenic storage vessel comprises a liquid storage volume, a conduit leading from that volume, a large flowable mass of solid spherical insulators within that conduit and a diaphragm at the end of the conduit opposite the liquid storage volume. The ambient pressure of the seawater surrounding the apparatus is transmitted to the cryogenic liquid by means of displacement of the diaphragm which is in contact with the ambient seawater and the corresponding change in the internal volume of the liquid storage apparatus. The mass of insulating spheres are allowed to flow within the conduit and partially into the liquid storage area upon displacement of the diaphragm. The insulators allow vapor of the liquid within their interstices but maintain a thermal gradient between the liquid and the diaphragm sufficient to protect the diaphragm from the extremely low temperatures of the cryogenic liquid by substantially preventing convection and conduction.

    Abstract: Apparatus and method for ''''peak shaving'''' storage of gas in a gas distribution system wherein the pressure varies from a maximum when demand is low to a minimum when demand is high, the method comprising cooling gas, in a gas storage chamber in open fluid communication with the system with a frozen cooling medium having a freezing point approximately midway between the minimum and maximum boiling points of the gas in the system. When the pressure in the system is high, gas in the chamber liquifies and is stored; when the pressure in the system is low gas in the chamber vaporizes and is available for use.
