Low-carbon power generation system and method using liquefied natural gas reforming coupled with gas turbine using abandoned electricity

Abstract

The present invention discloses a liquefied natural gas reforming coupled gas turbine low-carbon power generation system and method utilizing abandoned electricity. The present invention couples renewable energy power generation technology, liquefied natural gas reforming technology, LNG cold energy utilization technology and gas turbine low-carbon power generation technology, and is a distributed power generation system that efficiently couples gas turbine power generation, renewable energy power generation and energy storage system based on the principle of heat capacity flow rate matching and energy cascade utilization. When renewable energy such as photovoltaic and wind energy is sufficient, the system introduces surplus renewable electric energy into the liquefied natural gas reforming process to provide energy for the reaction, stores renewable electric energy with an efficiency far higher than that of water electrolysis, and uses LNG cold energy to multi-stage compress and cool the generated carbon dioxide, thereby achieving efficient and low-carbon operation of the system.
