Is liquid air energy storage a large-scale electrical storage technology?

You have full access to this open access article Liquid air energy storage (LAES) has been regarded as a large-scale electrical storage technology. In this paper, we first investigate the performance of the current LAES (termed as a baseline LAES) over a far wider range of charging pressure (1 to 21 MPa).

Can liquid air energy storage be combined with liquefied natural gas?

Kim J., Noh Y., Chang D., Storage system for distributed-energy generation using liquid air combined with liquefied natural gas. Applied Energy, 2018, 212: 1417–1432. She X., Zhang T., Cong L., et al., Flexible integration of liquid air energy storage with liquefied natural gas regasification for power generation enhancement.

Is packed-bed based cryogenic energy storage more efficient than indirect multi-tank storage?

Chai et al and Liao et al studied packed-bed based cryogenic energy storage both experimentally and numerically under super-critical (SC) conditions. They found that the exergy loss of direct heat transfer within the packed-bed was smaller than that of indirect multi-tank storage configurations .

Is liquid air energy efficient?

Their results showed an average liquid air yield increasing from 23% (at the start-up) to 56% (at the steady state), an RTE of ∼42.8%, and a combined heat and power energy efficiency of ∼82.1%.
