China liquid air energy storage

What is liquid air energy storage (LAEs)?

6. Concluding remarks Liquid air energy storage (LAES) is becoming an attractive thermo-mechanical storage solution for decarbonization, with the advantages of no geological constraints, long lifetime (30–40 years), high energy density (120–200 kWh/m 3), environment-friendly and flexible layout.

What is hybrid air energy storage (LAEs)?

Hybrid LAES has compelling thermoeconomic benefits with extra cold/heat contribution. Liquid air energy storage (LAES) can offer a scalable solution for power management, with significant potential for decarbonizing electricity systems through integration with renewables.

What is a liquid air energy storage plant?

2.1.1. History of liquid air energy storage plant The use of liquid air or nitrogen as an energy storage medium can be dated back to the nineteen century, but the use of such storage method for peak-shaving of power grid was first proposed by University of Newcastle upon Tyne in 1977 .

Can liquid air be used as a fuel for energy storage?

Barsali et al modelled a hybrid system with liquid air as an energy storage medium and LNG as a fuel, an equivalent RTE ranging from 82% with carbon capture at 100 bar to 104% without carbon capture at 150 bar can be obtained.

Is a liquid air storage system more efficient than a CAES system?

Kantharaj et al proposed a CAES system with liquid air storage, with an aim to overcome the needs for a pressurized large storage tank and the geological constraint of CAES. They found an efficiency of the hybrid system at about 42%, and concluded that the system was more economical than purely an LAES or a CAES system.

How can liquid air be produced from LNG regasification?

Che et al. proposed to produce liquid air by using cold energy from the LNG regasification process on-site, after which the liquid air is transported to a cold storage room for electricity supply (through a direct expansion cycle) and direct cooling supply (−29 °C).
