Abstract
Liquid hydrogen is one of the most efficient ways to store hydrogen. To reduce the energy loss in the liquid hydrogen cycle, the cold energy released at ultra-low temperature in hydrogen regasification should be utilized. Here, an integrated two-stage organic Rankine cycle power generation system for cold energy recovery from liquid hydrogen regasification is proposed. The designed system could recover some 15.3% of the cold energy and increasing the hydrogen cycle exergy efficiency to 71.8%. The working fluid pair R41/R1270 gave the best results and improved the net present value by 2.3%.
