# EU and Spanish green hydrogen deployment > Live situation record from CLSTR: https://clstr.news/situations/eu-green-hydrogen-deployment > Updated: 2026-08-24T11:03:11.000Z. Sources: 20. Developments: 6. In late June 2024 the EU‑funded INDTEGRATE project launched a three‑year pilot to demonstrate green‑hydrogen production for energy‑intensive sectors, combining renewable electricity, waste‑heat recovery and digital‑twin optimisation. By June 2026 the Horizon Europe‑funded INDTEGRATE consortium – comprising Greek development consultants, leading manufacturers, research centres and universities – held its inaugural meeting, outlining pilot installations of fuel‑cell systems and advanced digital‑twin tools in real industrial plants. In July 2026 the Spanish government, through the Institute for Diversification and Energy Savings (IDAE), granted Repsol €133.3 million to build a 50 MW PEM electrolyser at the Atlas plant in A Coruña and €49.8 million for a 12.27 MW project in Puertollano, with a ten‑year production subsidy of €2.2 per kilogram covering roughly 60 000 t yr⁻¹. The Andalusian Onuba hub continues to attract about €1 billion of investment. The EU’s Hydrogen Mechanism opened a new call for hydrogen‑related infrastructure, with expressions of interest due by 7 September 2026. A market survey for the Nordic‑Baltic Hydrogen Corridor forecasts annual demand of 79 TWh by 2040 and a corridor capacity of 91 TWh. In August 2026, Spain’s Ministry for the Ecological Transition (MITECO) approved €274.2 million in aid for renewable hydrogen projects in Castilla-La Mancha, Galicia, and Aragón, utilizing NextGenerationEU funds. Repsol emerged as the primary beneficiary, receiving approximately €183.18 million for its Atlas and P-HYNET projects. Other funding supported projects by Doña Urraca Energy (Quixotgen), AccionaPlug, and ZaragozaH2V. These subsidies certify 100% renewable hydrogen and require compliance with “do no significant harm” criteria. Simultaneously, industrial decarbonization efforts in Puertollano progressed with the Hydnum Steel project. Supported by €150 million from COFIDES and PERTE for Industrial Decarbonization, the project aims to build the Iberian Peninsula's first clean steel factory using green hydrogen and renewable energy, with total investments expected to exceed €1.5 billion. ## Timeline ### 2026-08-24: Green hydrogen technology advances as European industrial projects accelerate New catalyst technology aims to slash green hydrogen costs by 40 times, supporting a surge in European industrial electrolysis projects, including major hubs in Spain and Sweden. 2 sources. https://clstr.news/cluster/green-hydrogen-technology-advances-as-european-industrial-projects-accelerate ### 2026-08-11: Spain approves 274 million euros for green hydrogen projects Spain has approved 274.2 million euros in subsidies for four green hydrogen projects in Galicia, Aragon, and Castilla-La Mancha to drive industrial decarbonization. 3 sources. https://clstr.news/cluster/spain-approves-274-million-euros-for-green-hydrogen-projects ### 2026-08-08: Spain invests in green hydrogen and clean steel production Spain is advancing industrial decarbonization with €274.2 million in green hydrogen aid for projects like Repsol's, and a €150 million investment from COFIDES to build the first clean steel factory in Puertoll号 3 sources. https://clstr.news/cluster/spain-invests-in-green-hydrogen-and-clean-steel-production ### 2026-08-06: Spain allocates €233.4 million to green hydrogen projects by Repsol and Doña Urraca Spain's Ministry for the Ecological Transition allocated €233.4 million to three renewable‑hydrogen projects—Repsol’s Atlas (50 MW), Puertollano Hydrogen Network (12.27 MW) and Doña Urraca’s Quixotgen (30 MW)—s 7 sources. https://clstr.news/cluster/spain-allocates-2334-million-to-green-hydrogen-projects-by-repsol-and-doa-urraca ### 2026-07-22: Spain pushes green hydrogen expansion with Repsol funding and EU projects Spain funds Repsol’s 50 MW green‑hydrogen plant and a €1 bn Andalusian hub; the EU launches a new hydrogen‑infrastructure call, while a Nordic‑Baltic corridor aims for 79 TWh annual demand by 2040. 7 sources. https://clstr.news/cluster/europe-accelerates-green-hydrogen-market-with-new-projects-and-policy-proposals ### 2026-06-30: EU launches INDTEGRATE green hydrogen project to cut fossil fuel use EU’s INDTEGRATE project, funded by Horizon Europe, will test green‑hydrogen and digital‑twin solutions in industry to reduce fossil‑fuel use and help meet the 2050 climate‑neutrality goal. 2 sources. https://clstr.news/cluster/eu-launches-indtegrate-green-hydrogen-project-to-cut-fossil-fuel-use --- Cite as: EU and Spanish green hydrogen deployment.
