Abstract
A cold-heat power generation device includes a thermal power generation device, a CAES power generation device, and an output merging part. A facility includes an LNG vaporizer, a motive power part that burns natural gas vaporized by the LNG vaporizer to convert the natural gas into motive power, and a primary generator that is driven by the motive power part. A facility includes an air compressor that compresses air cooled by the LNG vaporizer, an air tank that stores compressed air discharged from the air compressor, air heaters that heat the compressed air supplied from the air tank with heat generated when the natural gas is burned in the motive power part, an air expander that expands the compressed air heated by the air heaters, and a secondary generator that is driven by the air expander. At the output merging part, output of the primary generator and output of the secondary generator are merged with each other.
