SSE Thermal Charts Path To Green Hydrogen Future With First-Of-A-Kind Project

The title of this post, is the same as that of this press release from SSE Thermal.

This is the sub-heading.

SSE Thermal is developing a first-of-a-kind project in the Humber which would unite hydrogen production, storage and power generation in one location by the middle of this decade.

These paragraphs explain the project.

The Aldbrough Hydrogen Pathfinder project will support the evidence base for wider deployment of flexible hydrogen power in the UK’s net zero journey and is a major enabler of SSE Thermal’s wider Humber ambitions.

Located at SSE Thermal and Equinor’s existing Aldbrough Gas Storage site on the East Yorkshire coast, the project is designed to demonstrate the interactions between hydrogen electrolysis, hydrogen cavern storage and 100% hydrogen dispatchable power.

The concept would see green power sourced from grid through Renewable PPAs, in compliance with the Low Carbon Hydrogen Standard. Hydrogen would then be produced via a 35MW electrolyser before being stored in a converted salt cavern and then used in a 100% hydrogen-fired turbine, exporting flexible green power back to grid at times of system need. In future, hydrogen storage will also benefit offtakers in other sectors, for example in industry, heat or transport.

Note.

  1. The Aldbrough Gas Storage site currently can store the equivalent of 320 GWh of electricity, It is currently being expanded to be one of the largest hydrogen stores in the world according to this page on the SSE web site.
  2. SSE Thermal are proposing to build a hydrogen-powered power station at Keadby to the South of the Humber. The press release says this power station could have a peak demand of 1,800MW of hydrogen.
  3. Aldbrough at its current size could keep the Keadby hydrogen-powered power station going for a week. But Aldbrough will be a lot bigger than the current 320 GWh.
  4. The Hornsea and Dogger Bank wind farms off the coast of East Yorkshire will have a capacity of at least 13.5 GW.
  5. A 35 MW electrolyser will produce 15.2 tonnes of hydrogen per day.

SSE and Equinor hope to be storing hydrogen by 2025.

Conclusion

It is an enormous project and it will surely grow with more electrolysers and hydrogen-powered power stations.
