The project is being undertaken by a joint venture between the British firm Highview Power and Carlton Power, an independent solar and gas power station developer.
It calls for the creation of a “cryogenic battery” with a 50 MW capacity (with the possibility of adding capacity at a later date) based on technology of mobile, long duration energy storage.
The battery acts in the same manner as a pumped hydroelectric energy storage station, but can be built at a wide variety of locations.
The project has already secured a grant of 10 million pounds ($12.5 million) from the British government.
A statement by Highview described the cryogenic system of energy storage – using frozen liquid air – as the sole long duration energy storage system currently available. The plants, it said, can provide multiple gigawatt hours – or several weeks – of storage.
