Repsol's Board of Directors has approved the development of a 150 MW electrolyzer at its Tarragona industrial complex, with an investment of approximately €400 million, which will generate around 1,000 jobs.

The Repsol Industrial Complex in Tarragona takes another step in its transformation with the approval by the company's Board of Directors of the development of a 150-megawatt (MW) electrolyzer, Repsol's largest to date. The new facility, to be developed jointly with Enagás Renovable, will supply renewable hydrogen to the Ecoplanta and other units within the industrial complex. The project involves an investment of approximately €400 million and the creation of around 1,000 direct, indirect, and induced jobs, primarily local, across its various phases.
The electrolyzer and Ecoplanta are two strategic and complementary projects for the future of the industrial complex. Ecoplanta will transform non-recyclable urban waste into renewable methanol and circular products, while the electrolyzer will supply renewable hydrogen to drive new production lines for lower-carbon footprint fuels and products. The project is developed by Repsol and Enagás Renovable, which holds a 25% stake. The alliance combines Repsol's industrial capacity and hydrogen consumption knowledge with Enagás Renovable's specialization in developing green molecule production projects.
The new facility will have a production capacity of over 22,000 tons of renewable hydrogen annually and is estimated to prevent up to 250,000 tons of CO₂ per year. The project has been selected for the state's Hydrogen Valleys program to receive funding of up to €104 million due to its strategic nature.
The new electrolyzer will help strengthen the role of Repsol's Industrial Complex as one of the main economic and employment drivers in the Camp de Tarragona region. This activity will generate new opportunities for local companies specializing in engineering, industrial construction, maintenance, and services, contributing to strengthening the local productive fabric.
