Atwick is a gas storage facility near Hornsea on the East Yorkshire Coast. There are nine caverns which provide the UK with gas storage capacity.

SSE also owns and operates Aldbrough Gas Storage facility, located further along the east coast.

To form caverns such as those at Aldbrough and Hornsea, salt deposits around 2km underground are leaches out by seawater which, in turn, is replaced (dewatered) by gas under pressure.


April 2018

Due to current market conditions, SSE took the decision to mothball some of the caverns at the Atwick site.

During this mothballing, a life extension project will be undertaken to enable the caverns to be retained in a good condition, and used again in the future if market conditions change.

Works on the life extension project will begin in April 2018, followed by further works towards the end of 2018.
