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 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. Simultaneously, industrial decarbonization efforts in Puertollano progressed with the Hydnum Steel project, aiming to build the Iberian Peninsula's first clean steel factory. By late August 2026, green hydrogen infrastructure expanded into aviation and public services. Aena contracted the installation of a hydrogen production and supply plant at Bilbao Airport. Repsol commenced construction on a 100 MW electrolyzer at the Petronor refinery in Muskiz, targeting 15,000 tons of annual renewable hydrogen production by 2029. ~~In September 2026, the Andalusian Green Hydrogen Valley gained momentum.~~
