Repsol approves 150 MW Tarragona electrolyser with investment of about €400 million
The project with Enagas Renovable targets industrial hydrogen demand at Ecoplanta and the Tarragona refinery.
The story explained
Repsol announced on 12 November that its board had approved development of a 150 MW electrolyser in Tarragona, Spain, involving approximately €400 million of investment. Enagas Renovable holds a 25% stake.
The planned facility would produce more than 22,000 tonnes of renewable hydrogen annually, mainly for Ecoplanta and refinery production of renewable methanol and lower-carbon products. Repsol says it will use reclaimed industrial water exclusively, with possible future supply to gas and hydrogen networks.
The project has been selected for up to €104 million under Spain’s Hydrogen Valleys programme. The announcement establishes development approval and design intentions, not operating output. It does not identify valve, pump or control-system suppliers.
Why it matters
Editorial assessment: interfaces with water treatment, hydrogen handling and existing process units warrant attention, but specific equipment purchases remain undisclosed.
