(IN BRIEF) Repsol, in collaboration with Enagás Renovable, will invest over €300 million in a 100 MW electrolyzer at its Cartagena complex, marking the company’s first major electrolyzer project. Scheduled to begin operations in 2029, the facility will produce 15,000 tonnes of renewable hydrogen annually, cut 167,000 tonnes of CO₂ emissions, and create 900 jobs. The electrolyzer will play a central role in the Hydrogen Valley of Murcia, advancing Spain’s renewable hydrogen ecosystem and strengthening Repsol’s position as the Iberian Peninsula’s leading hydrogen producer. Over time, the hydrogen produced could also be injected into the natural gas grid and contribute to the planned Spanish Hydrogen Backbone. The company currently manages a portfolio of 20 renewable hydrogen and biomethane projects across Spain.
