Patent number: 10876433Abstract: 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.Type: GrantFiled: February 2, 2017Date of Patent: December 29, 2020Assignee: Highview Enterprises LimitedInventors: Stephen Gareth Brett, Chris Bailey

Patent number: 10138810Abstract: Cryogenic energy storage systems, and particularly methods for capturing cold energy and re-using that captured cold energy, are disclosed. The systems allow cold thermal energy from the power recovery process of a cryogenic energy storage system to be captured effectively, to be stored, and to be effectively utilised. The captured cold energy could be reused in any co-located process, for example to enhance the efficiency of production of the cryogen, to enhance the efficiency of production of liquid natural gas, and/or to provide refrigeration. The systems are such that the cold energy can be stored at very low pressures, cold energy can be recovered from various components of the system, and/or cold energy can be stored in more than one thermal store.Type: GrantFiled: January 5, 2018Date of Patent: November 27, 2018Assignee: Highview Enterprises LimitedInventors: Robert Morgan, Stuart Nelmes, Nicola Castellucci, Stephen Gareth Brett
