Abstract
A system comprising a cryogenic storage tank for storing cryogen, a pump in fluid communication with the cryogenic storage tank for pumping cryogen from the cryogenic storage tank to a high pressure, an evaporator in fluid communication with the pump for evaporating the high-pressure cryogen from the pump to form a high-pressure gas, a power recovery apparatus comprising a drive shaft for transmitting mechanical power, and an electrical machine mechanically coupled to the drive shaft of the power recovery apparatus for converting the mechanical power recovered by the power recovery apparatus into electrical energy. The system is operable in a power recovery mode in which the power recovery apparatus is driven by and recovers mechanical power from high-pressure gas supplied by the evaporator, and a motored mode in which the power recovery apparatus is driven by a driving means other than high-pressure gas supplied by the evaporator.
