Spain is establishing itself as a pioneer in the green hydrogen sector, leveraging its substantial renewable energy capacity. With more than 50% of its electricity sourced from renewables, mainly wind and solar, Spain is aiming to achieve an impressive 11 GW of installed electrolyzer capacity by 2030, setting the highest target in the EU. To realize this ambitious goal, Spain will require additional support through subsidy programs, with the current projection for 2030 at 5 GW. Spain's advantageous renewable energy conditions and proactive governmental policies position it as one of the most cost-effective regions in Europe for green hydrogen production. Notable projects like the 20 MW Puertollano green hydrogen plant and the potential 2 GW expansion of BP's Castellón refinery by 2035 underscore Spain's capabilities in the hydrogen domain. With backing from the European Hydrogen Bank, a €794 million state aid package under the EU's IPCEI Hy2Use program, and an additional €2.3 billion in subsidies from the Spanish government, Spain is poised to strengthen its position in the hydrogen sector. As Spain accelerates its hydrogen initiatives, it faces stiff competition from countries like Germany, France, and the Netherlands, all heavily investing in this rapidly growing market.
