Equinor and SSE Thermal are stepping up ambitions to contribute to decarbonization in the UK. The companies are buying power company Triton Power from Energy Capital Partners (ECP), an energy-transition infrastructure investor, and are starting preparations to use H₂ in the Saltend Power Station.

The key plant included in the purchase of Triton Power is the Saltend Power Station with an installed capacity of 1.2 GW. This is a conventional combined cycle gas turbine (CCGT) that uses natural gas. The main role of this power plant today is to provide electricity during periods of low output from solar and wind. Equinor and SSE Thermal are now starting work on preparing the power plant to use up to 30% H₂ from 2027, with an ambition to eventually increase to 100% H₂ operation.

The H₂ could come from Equinor's H2H Saltend H₂ project, which would reform natural gas into H₂ by carbon capture and storage, capturing more than 95% of its CO₂ content. Saltend Power Station would then become an anchor customer for the H₂ project. With the purchase, Equinor and SSE Thermal could thus begin to decarbonize flexible power generation and at the same time contribute to triggering production of low carbon H₂ for industrial purposes as well.

"This acquisition together with SSE Thermal demonstrates our commitment to building a broad energy partnership with the UK. We will continue to work to supply the UK market with reliable energy and to reduce emissions by offering a transition to hydrogen through our hydrogen project H2H Saltend. Contributing to flexible power supplies with low CO₂ emissions to support weather-dependent renewable energy is essential to ensure energy security through the energy transition," said Irene Rummelhoff, Equinor's executive vice president for Marketing, Midstream and Processing.

"Flexible energy will be crucial as renewable energy scales up further over the coming years, providing important back-up and improving security of supply. But the real gain will be how we contribute to decarbonization in the longer term, and we are particularly excited about the possibilities for hydrogen and carbon capture in Saltend. Together with Equinor, we will explore all avenues to decarbonize Saltend and create new opportunities for other businesses so that they can operate in a future with net zero emissions," said Catherine Raw, CEO of SSE Thermal.

The Humber is the UK's largest industrial region with annual emissions of over 12 MMt of CO₂, which is over 50% more than from the second largest region. Decarbonization is essential for these industries to continue to operate as society move towards net-zero emissions. In addition to providing flexible power to support variable generation from renewables, the H2H Saltend hydrogen project will also support industries to switch from coal to hydrogen. This includes factories that are part of the Saltend Chemicals Park, which already is supplied with electricity and steam from the Saltend Power Station.

“This agreement will allow the Triton Power assets to continue to provide critical grid services and flexible power generation while building on the progress already made on decarbonization. I have been particularly impressed by the vision and commitment shown by SSE Thermal and Equinor in our discussions and believe they have the capabilities and knowledge required to allow our pipeline of clean energy projects to proceed at pace,” said Mick Farr, Chief Executive, Triton Power.

“Over the course of our ownership, ECP is proud of the progress we and the Triton team have made in re-positioning the portfolio for a rapidly decarbonizing world. With the redevelopment of Deeside into a carbon neutral provider of inertia completed; the H2H Saltend project underway; and this transition to experienced and similarly aligned new owners in SSE Thermal and Equinor, we believe the business will continue to serve as a model for environmentally responsible power generation amidst the ongoing energy transition,” said Rahman D’Argenio, Partner at ECP.

Equinor and SSE Thermal will acquire Triton Power for a total consideration of £341 MM. Once the transaction is complete, Equinor and SSE Thermal will own Triton Power through a 50:50 joint venture. The deal is expected to close in September, subject to approval from the UK National Security Filing and EU Merger Control.

The acquisition of Triton Power strengthens Equinor and SSE Thermal's portfolio of low carbon solutions in the UK. This already includes plans for H₂ power plants, H₂ storage and CCGTs with carbon capture and storage in Keadby and Peterhead, Scotland.
