- Cepsa selects Siemens Energy for 100 MW of proton-exchange membrane electrolysis technology, advancing the Andalusian Green Hydrogen Valley project.
- The project, part of Cepsa’s broader 2 GW hydrogen initiative by 2030, aims to integrate multiple technologies to ensure a reliable supply of green hydrogen for decarbonization across Europe.
Cepsa, based in Madrid, Spain, has engaged Siemens Energy AG, headquartered in Munich, Germany, to supply 100 MW of proton-exchange membrane (PEM) electrolysis technology. This technology will be a cornerstone in green hydrogen production at Cepsa’s La Rábida Energy Park in Palos de la Frontera, Huelva, as part of its ambitious plan to develop 400 MW of green hydrogen production in the region. This initiative is a segment of Cepsa’s broader strategy to establish 2 GW of hydrogen capacity by 2030, distributed equally between Huelva and Cádiz, positioning it as one of Europe’s most significant green hydrogen undertakings. The implementation of the first phase is awaiting a Final Investment Decision.
In conjunction with Siemens Energy’s PEM technology, Cepsa will employ alkaline water electrolysis for the remaining 300 MW of the project, currently being advanced with its partner, Fertiberia. This dual-technology strategy is reflective of Cepsa’s commitment to fostering a multi-supplier, European green hydrogen value chain, vital for the decarbonization of various industrial and transport sectors throughout the decade.
Carlos Barrasa, Cepsa’s Executive Vice President of Commercial and Clean Energies, emphasized the strategic nature of these partnerships: “Cepsa continues to execute important strategic agreements to develop the Andalusian Green Hydrogen Valley, enabling us to bring crucial green molecules to our customers as we support their decarbonization journeys. Produced at scale, green hydrogen can power Europe to a zero-carbon energy system. Through a combination of electrolyzer technologies, Cepsa can manage technology risk to ensure supply for our customers.”
Alexey Ustinov, Head of Sustainable Energy Systems at Siemens Energy, also commented on the collaboration: “We are delighted to be part of Cepsa’s ‘Green Hydrogen Valley’ project, as there will be no energy transition without green molecules. The industry is ready, production capacity of electrolyzers is no longer the bottleneck in ramping up the hydrogen economy. Our Berlin multi-gigawatt electrolyzer factory is a good example of this. But we need a faster pace of funding approvals and fewer technocratic hurdles to ensure that such projects can make their decisive contribution to decarbonization across Europe.”
The synergy between Siemens Energy’s advanced engineering and southern Spain’s abundant solar and wind resources creates an ideal environment for low-carbon electricity generation, essential for green hydrogen production. This strategic location not only provides competitive advantages but also facilitates the development of a maritime corridor by Cepsa and its partners for transporting hydrogen between southern and northern Europe, reinforcing decarbonization efforts continent-wide.
