Performance comparison of organic Rankine cycle (ORC) and CO2 cycle for simultaneous utilization of liquefied natural gas (LNG) cold energy and solar energy

Abstract

LNG is a good way to transport natural gas from suppliers to consumers. However, the LNG cold energy is generally lost during the regasification process at the receiving terminals. LNG cold energy can be a great heat sink for power cycles. Meanwhile, solar energy is abundant on the earth and it is a great heat source for the power cycles. If solar energy and the LNG cold energy can be utilized in an integrated power system, the efficiency of energy utilization and economical profitability would... »
