Could liquid air energy storage be a low-cost option?

New research finds liquid air energy storage could be the lowest-cost option for ensuring a continuous power supply on a future grid dominated by carbon-free but intermittent sources of electricity.

What is liquid air energy storage?

Liquid air energy storage (LAES) is a technology that converts electricity into liquid air by cleaning, cooling, and compressing air until it reaches a liquid state. This stored liquid air can later be heated and re-expanded to drive turbines connected to generators, producing electricity.

Could liquid air unlock a new opportunity for long-duration energy storage?

The world’s most available substance could unlock a new opportunity for long-duration energy storage. Liquid air refers to air that has been cooled to low temperatures, causing it to condense into a liquid state. Credit: Waraphorn Aphai via Shutterstock.

Are liquid air energy storage systems economically viable?

“Liquid air energy storage” (LAES) systems have been built, so the technology is technically feasible. Moreover, LAES systems are totally clean and can be sited nearly anywhere, storing vast amounts of electricity for days or longer and delivering it when it’s needed. But there haven’t been conclusive studies of its economic viability.

Are long duration energy storage systems the missing link to achieving 100 res?

ilment of RES generation. In this context, energy storage systems have become essential to increase the absorption of RESs in the power system and minimize any economic curtailment. Specifically, numerous independent studies have identified long duration energy storage (LDES) systems as the missing link to realizing 100

Can LPO finance energy storage projects?

LPO can finance short and long duration energy storage projects to increase flexibility, stability, resilience, and reliability on a renewables-heavy grid. Why Energy Storage?
