liquid air energy storage

Independent energy infrastructure developer Carlton Power has secured planning consent for a 1,040 MW/ 2,080 MWh battery energy storage system (BESS). The project is expected to strengthen the resilience of the energy system in northwestern England.

An international group of researchers has designed a new hybrid photovoltaic-liquid air energy storage (PV-LAES) system. Their economic evaluation for the proposed 2 MW PV-LAES project showed that the investment payback period can be within 10 years, and the accumulated net profit can reach up to $2.2 million from a life-cycle perspective.

A UK consortium has developed the Prisma system, which stores thermal energy in liquid air form to provide onsite compressed air, via a latent energy cold storage tank filled with a phase-change material. It is expected to have a levelized cost of storage of GBP 114 ($143.10)/MWh.

Finland-headquartered Sumitomo SHI FW has entered a collaboration with China’s Shanghai Power Equipment Research Institute to evaluate the feasibility of long-duration energy storage using liquefied air energy storage technology.

The British company, which has tested its liquid air energy storage technology in the U.K., says it is preparing to deploy its first plant on U.S. soil. Highview claims its CRYOBattery is half the price of utility scale lithium-ion storage.

The long-duration energy storage provider plans to eventually build a portfolio of 50 MW/250 MWh liquid air systems throughout the United Kingdom.
