SSE begins work on hydrogen storage cavern on Yorkshire coast

Exclusive: renewable energy will be kept in cathedral-sized cave for freezing, windless conditions

The energy company SSE has begun work to develop an underground cavern in Yorkshire to store hydrogen, aiming to stockpile the renewable source of power for when the freezing, windless conditions seen in the last week occur in future.

The project will see hydrogen produced using renewable energy in a 35-megawatt electrolyser before being stored in a cavern the size of St Paul’s Cathedral, located a mile deep at an existing SSE site in Aldbrough on the Yorkshire coast.
