Query from Parish Council Question to Carlton Power, 25th August 2020 :

Are there any safety issues associated with the storage of liquid air in the CryoBattery facility ?

Answer :

The CryoBattery technology uses the compression and liquefaction of air to store energy until it is needed by the electricity system. Air from the atmosphere is compressed, cooled and expanded in a series of stages until it becomes liquid and it is then stored in insulated tanks. When the CryoBattery needs to supply power back to the grid the air is expanded and reheated before passing through an air turbine to generate electricity. During the liquefaction process dust is trapped on the inlet filters then water vapour and carbon dioxide are removed and released back to ambient, this means that when the liquid air is evaporated and expanded during the discharge process the air that is emitted back into the atmosphere is cleaner than the air that was drawn into the compressor at the beginning of the process. The primary safety issue in relation to liquid air is that it is an extremely cold fluid and precautions must be taken when storing it. The equipment used in the process is well proven and the tanks and pumps are designed to minimise any chance of releasing the cold liquid air back into the atmosphere. Whilst the air stored in the CryoBattery plant is ultimately released back into the atmosphere, the design of the CryoBattery plant is intended to ensure that this only happens once it has been fully expanded and reheated. The liquid airstorage vessels which hold the liquid air are twin walled and made of a Nickel-steel alloy. In the unlikely event of an uncontrolled leakage of inventory, the liquid air is contained within a concrete wall and will evaporate slowly back into the atmosphere leaving no residue.
