Abstract
A system for better utilization of liquefied natural gas (LNG) on gasification of the liquid includes a gas power generation subsystem, a steam power generation subsystem, an energy storage subsystem, and a cooling subsystem. A gasification device of the gas power generation subsystem renders the LNG gaseous and collects cold energy generated during the gasification. The gas is supplied to the gas power generation device for generating electrical power and the cold energy is supplied to the steam power generation subsystem and the cold storage subsystem. Electrical power generated by the gas power generation subsystem and the steam power generation subsystem is supplied to the cooling subsystem, and the energy stored in the energy storage subsystem is also supplied to the cooling subsystem.
