제목 Systems design of a novel self-recuperative liquid air energy system
초록 Cryogenic energy storage systems are surfacing as a sustainable solution to the energy security and intermittency issues associated with renewable energy. Liquid air has already made it to the demonstration level and showed great potential for large-scale adoption. Liquid air may also be used for energy transport and transmission to off-terrain and for peak time demands. Air is liquefied during the off-peak times and regasified to generate electricity during crunch times. One of the primary concerns regarding LAES is its somewhat lower round trip efficiency of ~50%. In the present study, a novel self-recuperative scheme for the liquid air energy storage system is proposed. The process uses the stored liquid air as a refrigerant rather than external refrigerants as in conventional systems. The best-case scenario recuperates the cold box as well as the heat from all the compressors during the discharge cycle before recovering the power. The novel approach help achieve the highest round-trip and exergy efficiencies. The proposed process may likely revolutionize the whole energy shift paradigm.
