System for Liquid Air Energy Storage using Liquefied Gas Fuel

摘要

The present invention is to store the liquid air by using the cold heat of the liquefied gas supplied to the engine using the liquefied gas as fuel, to improve the overall system efficiency, such as fuel supply, power production and liquid air regasification process, liquefied gas It relates to a liquid air storage system using the cold heat of the fuel. A liquid air storage system using cold heat of liquefied gas fuel according to the present invention includes: a fuel supply unit supplying liquefied gas fuel to an engine using liquefied gas as fuel; An air liquefaction unit for liquefying air; And a regasification unit for re-vaporizing the liquefied liquid air to produce electric power, wherein the air liquefaction unit exchanges the liquefied gas with air to be liquefied to liquefy the liquefied gas to be supplied to the engine and liquefy the air. It includes; a first heat exchanger.
