Moeve Approves Final Investment Decision To Begin Construction Of Andalusian Green Hydrogen Valley, Launching Southern Europe’s Largest 300 MW Green Hydrogen Project

Moeve’s Board of Directors has formally approved the final investment decision to commence construction of the Andalusian Green Hydrogen Valley, setting the stage for one of Europe’s most significant clean-energy milestones. Work on the project’s first phase, Onuba, is scheduled to begin within the coming weeks. With an installed capacity of 300 MW and an optional 100 MW expansion, Onuba is poised to become the largest green hydrogen facility in Southern Europe, placing Spain at the forefront of the continent’s energy transition.

The scale of Onuba reflects a long-term strategic vision. The project represents more than €1 billion in total global investment, encompassing the hydrogen plant itself, essential infrastructure, and a self-consumption photovoltaic plant that will supply renewable electricity for production. Moeve leads the initiative with a 51% stake, joined by Masdar, a global clean energy pioneer, and Enalter, which is majority-owned by Enagás Renovable, a company recognized for its leadership in renewable gas development. Together, these partners bring extensive capabilities in hydrogen, renewables, and large-scale infrastructure, setting a solid foundation for the valley’s success.

For Moeve, Onuba is deeply aligned with its Positive Motion transformation strategy. According to CEO Maarten Wetselaar, the launch of Southern Europe’s largest green hydrogen plant marks a defining moment for the company. He described the project as the anchor of a world-class hub for green molecules in Spain, capable of supplying renewable fuels to hard-to-abate sectors while contributing to Europe’s broader energy and industrial resilience. He emphasized that working alongside other leaders in clean energy enables the creation of an ecosystem designed for scale and long-term impact.

Masdar’s CEO, Mohamed Jameel Al Ramahi, noted that the company has been an early mover in the green hydrogen sector, recognizing its importance in decarbonizing industries that are difficult to electrify. He explained that the partnership with Moeve fits Masdar’s strategy of backing commercially viable green hydrogen projects in markets with clear demand. He also highlighted the company’s support for Spain’s clean energy goals, which continue to accelerate the country’s leadership in renewable technologies.

From Enagás Renovable’s perspective, the project is equally transformative. CEO Antón Martínez stated that Onuba represents a major step forward for Spain’s green hydrogen landscape. He added that the Andalusian Green Hydrogen Valley showcases how coordinated efforts across companies and institutions can advance decarbonization while creating new industrial opportunities, supporting energy independence, and generating long-term economic and social value through job creation.

The project has already earned recognition at the European level. It has been designated as a Project of Common European Interest (PCI) by the European Commission, a status reserved for critical cross-border infrastructure and innovation efforts. To support its development, the Government of Spain has allocated €304 million in funding from the Recovery, Transformation and Resilience Plan, backed by the European Union’s NextGenerationEU program under the Hydrogen Valleys scheme. This funding covers the development of 400 MW of capacity for the Andalusian Green Hydrogen Valley.

While Onuba is launching with 300 MW of confirmed capacity, the additional 100 MW expansion option will proceed once further grid capacity is secured and receives board approval. The phased approach ensures flexibility while maintaining the project’s long-term ambition of becoming a leading hub for renewable hydrogen production. At 300 MW, Onuba will have the ability to produce approximately 45,000 tonnes of green hydrogen annually. This will help avoid an estimated 250,000 tonnes of CO2 emissions each year, equivalent to offsetting more emissions than those generated by all internal combustion passenger vehicles in the Spanish cities of Huelva, Cádiz, and Jaén. These figures highlight the significant decarbonization benefits of the initiative and its potential contribution to national and European climate objectives.

The green hydrogen produced at Onuba will serve multiple sectors. It will be used to create renewable fuels for aviation, as well as for road and marine transport, helping industries transition toward low-carbon logistics. Additionally, the hydrogen will support the decarbonization of chemical and fertilizer industries, both of which rely heavily on hydrogen as a feedstock and have historically been among the hardest sectors to reduce emissions in. By enabling cleaner alternatives at scale, Onuba sets the stage for a new industrial ecosystem built around renewable hydrogen solutions.

The Andalusian Green Hydrogen Valley represents far more than a single infrastructure project—it is a strategic investment in Europe’s energy future. With strong partnerships, substantial public support, and a clear industrial roadmap, the initiative positions Spain as a leader in the emerging hydrogen economy. As construction begins and the valley takes shape, it is expected to play a pivotal role in driving industrial decarbonization, enhancing regional competitiveness, and supporting economic resilience for decades to come.
