Air energy and photovoltaic energy storage integrated

Can photovoltaics and liquid-air energy storage work together?

A typical scenario for the proposed PV-LAES system. Researchers from the Sichuan Normal University in China and the University of Cambridge in the UK have investigated the techno-economic feasibility of a new hybrid system integrating photovoltaics and liquid-air energy storage (LAES).

How does a solar energy storage system work?

The LAES unit utilizes surplus power from the PV plant and compensates power for the local load with an inadequate power level. The system’s energy storage duration at the off-peak time is 9.13 hours, and the energy release duration at peak time is 6.27 hours.

How long does a solar energy storage system last?

The system’s energy storage duration at the off-peak time is 9.13 hours, and the energy release duration at peak time is 6.27 hours. For the proposed PV-LAES project, results show that the surplus renewable electricity of 6.73 MWh sent to LAES is used for generating 27.12 tons of liquid air for energy backups during the daytime.
