Advancements in cryogenic energy storage systems, particularly Liquid Air Energy Storage (LAES), have shown significant potential for revolutionizing grid-scale energy storage. LAES systems utilize excess electrical energy, often from renewable sources, to liquefy atmospheric air at cryogenic temperatures, storing it until needed for energy generation. Recent studies have focused on optimizing LAES efficiency, with research showing potential for round-trip efficiencies of around 60%. To further enhance performance and reduce costs, integrating cryogenic energy storage technologies has been proposed. This integration can significantly improve system efficiency, with liquid yields reaching 89% and notable reductions in power use. Additionally, studies have explored the integration of Liquid Hydrogen (LH2) regasification with LAES, resulting in remarkable efficiency gains, with some setups achieving round-trip efficiencies exceeding 400%. The utilization of LH2 cold energy presents opportunities for enhanced efficiency and economic viability in large-scale energy storage. Moreover, the incorporation of ORC technology in LNG/LH2 cold energy recovery processes has shown promising results, particularly in boosting electricity generation and overall system efficiency. Innovative approaches that combine advanced refrigeration techniques, alternative cold energy sources, and hybrid energy storage systems are at the forefront of research, aiming to optimize energy storage systems for a sustainable and efficient energy future.
