Electricity Generation Device and Method

摘要

There is disclosed a device and method for the generation of zero emission electricity that can be used to provide load balancing and emergency support to a electricity distribution network or back up electricity to a critical consumer such as a hospital or data centre. The system uses a cryogenic fluid and a source of low grade waste heat. A cryogenic fluid is first evaporated by an evaporator (3) heated by a superheater (4) before entering an expansion turbine (10) to produce electricity

主权项

1. An electricity generation device comprising:
a storage tank for storing a cryogenic fluid, a fluid pump for compressing cryogenic fluid taken from the storage tank to a high pressure, an evaporator for evaporating the high pressure cryogenic fluid, to provide a high pressure gas, a superheater for heating the high pressure gas to a high temperature using a source of heat from a co-located process, and an expansion turbine for expanding and extracting work from the superheated high pressure gas and for driving a generator to produce electricity from the rotational energy produced by the expansion turbine, wherein the evaporator is for evaporating the high pressure cryogenic fluid using the low pressure exhaust from the expansion turbine.
