United Kingdom – Equinor and SSE Thermal plan to jointly develop two first-of-a-kind, low-carbon power stations in the UK’s Humber region.
The project will comprise one of the UK’s first power stations with carbon capture and storage (CCS) technology, and the world’s first 100% hydrogen-fueled power station.
Transition to net zero
The plans, underpinned by a new cooperation agreement between the two companies, would support the UK’s transition to net zero and accelerate the decarbonization of the Humber, the UK’s largest and most carbon-intensive industrial cluster.
Clean power hub
The two decarbonized power stations, which would form a ‘clean power hub’ near Scunthorpe, North Lincolnshire, would be among the first in the world to utilize CCS and hydrogen technologies. Keadby 3 and Keadby Hydrogen would replace older, carbon-intensive generation on the electricity grid, providing flexible and efficient power to support intermittent renewable generation and maintain security of supply through the net zero transition.
These projects would also result in the Humber making a significant contribution to the UK’s 2030 targets for CCS and hydrogen. Keadby 3 could deliver 15% of the target for 10MT of carbon captured annually by 2030, while the demand from Keadby Hydrogen could account for a third of the 5GW hydrogen production goal.
Keadby 3 would be a 900MW power station fueled by natural gas and fitted with carbon capture technology to remove the CO2 from its emissions. The captured CO2 would then be transported using shared pipelines before being securely stored under the Southern North Sea.
A formal consultation for Keadby 3 concluded in early 2021 and the project is currently progressing towards the submission of a development consent application in Spring 2021. Keadby 3 would have the potential to come online by 2027, in line with Government ambitions for ‘Track 1’ industrial cluster projects.
Keadby Hydrogen power station would have a peak demand of 1,800MW of hydrogen, producing zero emissions at the point of combustion. It would be the world’s first major 100% hydrogen-fired power station, securing at-scale demand for hydrogen in the region for decades to come. With appropriate policy mechanisms in place, Keadby Hydrogen could come online before the end of the decade.
The Keadby 3 and Keadby Hydrogen projects are both in the development stage and the companies will continue to engage government, regulators and stakeholders. Final investment decisions will depend on the progress of policy frameworks that are commensurate with the delivery of this critical net zero enabling infrastructure.
The projects would utilize the parallel hydrogen and CO2 pipeline infrastructure being developed by the Zero Carbon Humber (ZCH) partnership – which includes Equinor and SSE Thermal – and offshore CO2 infrastructure developed by the six-member Northern Endurance Partnership (NEP), which includes Equinor. Both ZCH and NEP won public funding from the UK’s Industrial Strategy Challenge Fund in March.
Equinor’s H2H Saltend project will be the first to connect into the ZCH infrastructure and will come online by the mid-2020s. Like the additional hydrogen that would be produced for the Keadby Hydrogen project, H2H Saltend will provide low-carbon hydrogen to already-identified customers.
Equinor – SSE Thermal collaboration
As part of the agreement, SSE Thermal and Equinor are also developing options for hydrogen blending at SSE Thermal’s Keadby 2 project (already under construction), aiming to progressively decarbonize the UK’s newest and most-efficient power station. The companies also have the intention to collaborate on projects elsewhere in the UK.
Today’s agreement builds on the longstanding partnership between Equinor and SSE in the UK, which includes joint ownership of the Aldbrough Gas Storage facility in East Yorkshire, and the joint venture to build the Dogger Bank Offshore Wind Farm, the largest offshore wind farm in the world.
