4 FAQs about Liquid air energy storage system investment

Could liquid air be a viable energy storage solution?

A team of researchers from MIT and the Norwegian University of Science and Technology (NTNU) has been investigating a less familiar option based on an unlikely-sounding concept: liquid air. “Liquid air energy storage” (LAES) systems have been built, so the technology is technically feasible.

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.

How much does liquid air storage cost?

In simple terms, the LCOS is the cost of storing each unit of energy over the lifetime of a project, not accounting for any income that results. On that measure, the LAES technology excels. The researchers' model yielded an LCOS for liquid air storage of about $60 per megawatt-hour, regardless of the decarbonization scenario.

How efficient is a liquid air storage system?

The research placed the efficiency for a liquid air storage system's complete charge and discharge cycle at 20%-50%, though Highview rebutted with a 50%-60% round-trip efficiency estimation for a standalone system. Either way, LAES lags behind PSH (65%-85%) and batteries (80%-95%) in efficiency.
