Advanced natural gas liquefaction and regasification processes: Liquefied natural gas supply chain with cryogenic carbon capture and storage

•Cryogenic CO2 capture and storage (CCS) reduces power generation efficiency penalty.•Power consumption during natural gas liquefaction decreases by up to 67.17%.•Liquefied natural gas (LNG) supply chain with cryogenic CCS reduces energy waste.•Natural gas liquefaction and regasification are integrated based on cryogenic CCS.•The exergy efficiency in the LNG supply chain is increased from 18.18 to 46.39%.
