Centrica has inked a £20 billion deal with Norway's Equinor for a decade-long supply of natural gas, with a forward-looking clause for potential hydrogen substitution. Equinor, a long-time gas supplier to the UK, has gained importance amid the UK's move away from Russian energy imports. The UK's reliance on imported gas, despite having North Sea reserves, is due to global trading dynamics and high domestic demand. The new Centrica-Equinor agreement marks a significant step with its hydrogen clause, allowing Equinor to fulfill supply commitments with UK-produced hydrogen. Equinor aims to support the UK's target of 10 GW of low-carbon hydrogen production by 2030 through various hydrogen projects. The Humber Hydrogen Hub, a collaboration between Centrica, Equinor, and SSE Thermal, plans to develop substantial green and blue hydrogen capacity. Centrica's emphasis on hydrogen storage and the potential role of hydrogen in home heating align with the UK's climate goals. While the government supports hydrogen blending into the gas grid, decisions about widespread hydrogen usage, especially in heating, are awaited. The evolving energy landscape in the UK reflects a shift towards renewable energy sources and the integration of hydrogen in strategic sectors.
