Spain's Repsol Approves 150MW Green Hydrogen Electrolyzer Project in Tarragona

en.Wedoany.com Reported - On November 12, the board of directors of Spanish energy company Repsol approved a partnership with Enagás Renovable to develop a 150MW renewable hydrogen electrolyzer at the Tarragona industrial complex in Spain, with a planned investment of approximately EUR 400 million. Repsol will lead the project development, with Enagás Renovable holding a 25% stake. The facility is designed to produce more than 22,000 tonnes of renewable hydrogen per year, primarily supplying the local Ecoplanta circular economy plant and Repsol's refinery for the production of renewable methanol and low-carbon products.

The new facility will use water electrolysis to produce hydrogen, with recycled industrial water used in the production process. Once the electrolyzer is operational, the hydrogen will be fed preferentially into Tarragona's existing industrial production system, replacing some conventional hydrogen feedstock and providing raw material for renewable methanol production and other low-carbon chemical products. The project also reserves the possibility of future delivery of renewable hydrogen to the natural gas grid and Spain's national hydrogen backbone network.

The project is expected to create approximately 1,000 direct, indirect and induced jobs, mainly concentrated in the local area across different implementation phases. According to Repsol's published estimates, once the electrolyzer is in operation, it can reduce carbon dioxide emissions by up to 250,000 tonnes per year. The project has been selected for the list of strategic projects under Spain's national hydrogen valley program and is eligible for up to EUR 104 million in funding support from the EU Next Generation funds under the framework of Spain's Recovery, Transformation and Resilience Plan.

The Tarragona project is the third large-scale renewable hydrogen electrolyzer planned by Repsol and the second large-scale project jointly advanced with Enagás Renovable, following the Cartagena electrolyzer previously developed by the two partners. Including Tarragona, Repsol's three large-scale electrolyzers in Cartagena, Bilbao and Tarragona have a total planned capacity of 350MW.
