Highview Power Storage has developed and built a pilot energy storage system plant using liquid air to stop wrong time energy. The system can be scaled to 100 MW/GWh of energy storage, similar to medium scale pumped hydro.

Toby Peters, Co-Founder of Highview and COO, says: "If you want a low-carbon grid, what you want to do is manage your resources the best you can, which is what energy storage allows you to do. The grid will need a lot more reserves and balancing solutions as more wind and renewables are deployed, and energy storage is one route where you capture 'wrong time energy' and shift it to the right time.

“Whereas many companies were focusing on fast response but relatively small scale battery technologies, we started out five years ago to develop a system which could deliver affordable, long duration, large scale energy storage without geographical constraints.”
