Abstract
The present invention relates to cryogenic energy storage systems for storing using high-grade heat-of-compression. The system includes a liquefaction sub-system () and thermal energy storage device (). The liquefaction sub-system () includes a first compressor (), a first, second and third heat exchanger () and second compressor (). The first and second heat exchangers () are configured to transfer the high-grade heat of compression from the first and second compressors () respectively to the thermal energy storage device (). The third heat exchanger () is configured to recuperate the low-grade heat of compression from the second compressor () back into the second compressor () enabling the second compressor () to generate high-grade heat of compression. Further systems use compressors () and expanders (). Further systems include power recovery sub-systems (). The present disclosure also relates to methods of heat-of-compression storage in cryogenic energy storage systems.
