NOVELTY - An electric generator system for use in a facility storing liquid hydrogen, comprises a liquid hydrogen storage tank (16), valve (18) connected to the storage tank, and hydrogen conversion device (28) fluidly connected to the valve.    USE - The system is used for generating electricity at facilities storing liquid hydrogen for generating power (claimed).    ADVANTAGE - The system can recapture some of the energy lost during the storage of liquid hydrogen and transform the energy into a useful form that can be used by the storage facility. Electricity created by the generator can be fed back to operate ancillary loads in the facility, or sold for use in main electrical grid.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a method for generating electricity comprising storing liquid hydrogen in a storage tank, capturing boiled off hydrogen gas from the storage tank, storing the hydrogen gas, fueling a hydrogen conversion device with the hydrogen gas, and generating electricity with the hydrogen conversion device;    (2) a method of generating power in a liquid hydrogen storage facility having ancillary and control equipment, comprising operating hydrogen conversion device with hydrogen gas, generating electricity with hydrogen conversion device, and operating ancillary and control equipment with generated electricity;    (3) a pumping system comprising a liquid hydrogen storage tank, hydrogen conversion device fluidly connected to the tank, and pump(s) (14, 20) connected to the hydrogen conversion device; and    (4) method of operating a pump comprising storing hydrogen gas, fueling hydrogen conversion device with the hydrogen gas, and rotating the pump(s) with the hydrogen conversion device.    DESCRIPTION OF DRAWING(S) - The figure is a schematic diagram showing a system for generating electricity at a liquid hydrogen storage facility.    Pumps (14, 20)    Storage tank (16)    Valve (18)    Buffer tank (26)    Hydrogen conversion device (28)    Electrical grid (32)    Pressure relief valve (34)    Electrical generator (38)
