CRYOBattery™ (Electricity Storage): liquid air energy storage system
Led by Highview Enterprises Limited (trading as CRYObattery One Limited)
The objective of the project is to deploy the world’s first commercial-scale liquid air energy storage system (or CRYOBattery™). The technology uses surplus electricity from the transmission network to condense atmospheric air into a liquid. When the CRYOBattery™ is required to discharge its stored energy, it exhausts only clean air to the environment whilst dispatching electrical power. The plant will have an electrical output of 49.9 MW which can be sustained for five hours duration. This is the equivalent of powering 200,000 UK homes.
The CRYOBattery™ plant will demonstrate that at scale, cryogenic energy storage can deliver clean, smart and flexible power, utilising local supply chains (where possible) during construction and operation, thereby creating and securing jobs in the North West region.
Grant award: £10,000,000.00
Whitelee Hydrogen Production & Storage Facility
Led by ITM Power and BOC
The objective of this project is to demonstrate hydrogen’s role in a flexible energy system, and ability to store large quantities of energy over an extended time. It will demonstrate the dynamic response and flexibility of hydrogen production at scale, optimising the timing of hydrogen production to align with renewable outputs. The facility will include 5 tonnes of electrolysed hydrogen storage, providing up to 200MWh of large scale long-duration chemical energy storage. This technology will enable system flexibility for the grid which is a key challenge in the energy transition. The hydrogen produced will provide a low carbon fuel supporting decarbonation of transport.
A 10 MW PEM (proton exchange membrane) electrolyser will use renewable electricity to produce 2.5 to 4 tonnes of green hydrogen per day. When built, it will be the UK’s largest PEM system co-located with the UK’s largest onshore wind farm, Whitelee Windfarm near Glasgow.
Grant award: £9,447,509
