Latest news on liquid air energy storage

Are liquid air energy storage systems effective?

Liquid Air Energy Storage systems have the potential to be a competitive local and grid scale energy storage technology. They also have the potential to facilitate the penetration of renewable energy technologies. However, there is a clear disconnect between what has been proven in literature, and what has been demonstrated in practice.

Can a liquid air energy storage system overcome a major limitation?

Korean scientists have designed a liquid air energy storage (LAES) technology that reportedly overcomes the major limitation of LAES systems - their relatively low round-trip efficiency.

How much does liquid air energy storage cost?

Highview is also planning a further four, bigger liquid air plants, including one in Scotland. Like many LDES technologies, though, liquid air energy storage is expensive. Broadly speaking, for a first-of-a-kind project the storage costs might be about £500 per kilowatt hour, versus about £300 per KWh for a lithium ion battery.

Who is backing a liquid air energy storage project?

The syndicate backing the project — under development by private company Highview Power — also includes Rio Tinto and Goldman Sachs Power Trading. Highview is also planning a further four, bigger liquid air plants, including one in Scotland. Like many LDES technologies, though, liquid air energy storage is expensive.

How does liquid air energy storage work?

Enter liquid air energy storage, which has no such geographic restrictions. This works by using electricity during periods of abundant wind and solar generation to clean, dry and refrigerate air until it liquefies. The liquid air is then stored in insulated tanks.

What is long duration energy storage (LDEs)?

Greater deployment of wind and solar will also bring benefits for other technologies — including newer energy storage methods such as liquid air. Definitions of long duration energy storage (LDES) can vary but typically it is any technology that can store electricity for periods ranging from eight hours to weeks and months.
