Repsol is stepping up its industrial decarbonization drive with the approval of a €400 million investment in a 150-megawatt (MW) electrolyzer in Tarragona, set to become the company’s largest renewable hydrogen facility to date.

 

The project, developed in partnership with Enagas Renovable, which holds a 25% stake, will produce more than 22,000 metric tons of renewable hydrogen annually. The hydrogen will primarily supply Repsol’s Ecoplanta and other refinery units, supporting the production of renewable methanol and other low-carbon products.

 

Once operational, the facility is expected to prevent up to 250,000 metric tons of CO₂ emissions annually, marking a significant step in Repsol’s efforts to transform its industrial operations and strengthen their long-term competitiveness.

 

The project also leaves the door open for future supplies of renewable hydrogen to Spain’s natural gas network and the Spanish Hydrogen Backbone.

 

Beyond its decarbonization ambitions, the project is expected to deliver a substantial economic boost to the region, generating around 1,000 direct, indirect and induced jobs, primarily for the local workforce, across its various development and construction phases.

 

Repsol said the investment reinforces its commitment to Spanish industry and the transformation of its industrial sites into competitive, future-ready production hubs.

 

Repsol’s director of Renewable Hydrogen, Maribel Rodríguez, said: “This electrolyzer and the Ecoplanta represent an integrated industrial platform that places Tarragona at the heart of our transformation. Together, they will enable us to incorporate new technologies and capabilities to produce renewable fuels and products with a low carbon footprint at scale, strengthen the complex’s competitiveness, and help sustain an essential, innovative and future-ready industry in Europe.”

 

The approximately €400 million initiative has been selected to receive up to €104 million in funding under Spain’s Hydrogen Valleys programme.

 

The funding programme, promoted by the Ministry for the Ecological Transition and the Demographic Challenge, operates under Spain’s Recovery, Transformation and Resilience Plan and is financed through the European Union’s NextGenerationEU funds.

 

The support recognizes the project’s scale and its ability to link renewable hydrogen production directly with industrial consumption and the manufacture of renewable fuels.

 

The partnership brings together Repsol’s industrial expertise and established hydrogen demand with Enagas Renovable’s experience in developing green molecule production projects.

 

Enagas Renovable is jointly owned by Hy24 (80%) and Enagas (20%) and develops projects across Spain aimed at decarbonizing industry and heavy-duty transport.

 

Luis Iglesias, Enagas Renovable’s director of Business Development and Hydrogen Operations, said: “With this project in Tarragona, we are expanding our partnership with Repsol and strengthening our commitment to bringing renewable hydrogen to locations where industrial demand already exists. This is a project of significant scale that adds to the network of industrial hubs that are positioning Spain as a leader in green molecules in southern Europe.”

 

The Tarragona electrolyzer marks another major step in Spain’s ambition to establish itself as a European hub for renewable hydrogen, while positioning Repsol’s industrial complex at the forefront of the transition to lower-carbon fuels and products.
