We hold around 40% of the UK’s conventional underground gas storage capacity at our two sites on the East Yorkshire coast.

Our Atwick facility, near Hornsea, is wholly-owned by SSE Thermal, while the Aldbrough facility is operated as a joint venture with Equinor.

These two sites offer valuable flexibility and hedging services to the UK and interconnected gas markets.

As part of our transition to a net zero future, we are exploring opportunities to convert our gas storage facilities to store low-carbon hydrogen, which can be used to decarbonise power generation, industry, heat, transport and other key sectors.
