Spain turns renewable resources into industrial ambition.
Huelva, Spain.
Spanish energy company Moeve has begun construction of Onuba, the first phase of the Andalusian Green Hydrogen Valley, with an investment exceeding €1 billion. The project, launched in Palos de la Frontera on September 17, will initially provide 300 megawatts of electrolysis capacity, expandable by another 105 megawatts. Moeve presents the development as the first stage of what it expects to become Europe’s largest green hydrogen project. Its construction marks a significant industrial commitment at a time when geopolitical instability is intensifying European concerns over imported energy.
The facility is designed to produce approximately 45,000 tonnes of renewable hydrogen annually, potentially avoiding 250,000 tonnes of carbon dioxide emissions each year. Its output will support lower-carbon fuel production for road transport, aviation and maritime activities while supplying industrial processes that remain difficult to electrify directly. According to Moeve, development and construction could support more than 8,000 direct, indirect and induced jobs throughout the value chain. More than 400 local small businesses and self-employed professionals are expected to participate.
The investment combines private capital and European financial support. Moeve controls 51% of Onuba, while hydrogen investment fund Hy24 and Spain’s COFIDES jointly hold 29%, with Enagás Renovable and Alter Enersun accounting for the remaining 20%. The project has received €304 million in funding through Spain’s recovery plan, financed by the European Union’s NextGenerationEU program. This financing structure illustrates how public resources and private investment are being combined to develop emerging energy technologies at an industrial scale.
Spain’s geographical advantages constitute an important part of the project’s economic rationale. Andalusia offers abundant solar resources, favorable wind conditions and land for renewable electricity generation, a critical input in green hydrogen production. Moeve intends to expand the wider hydrogen valley to two gigawatts of electrolysis capacity across its energy facilities in Huelva and San Roque, Cádiz. The company is also examining pipeline and maritime transportation options to connect future production with industrial consumers elsewhere in Europe.
The project’s launch comes amid heightened energy market uncertainty linked to conflicts involving Iran and Ukraine. Spanish Prime Minister Pedro Sánchez used the inauguration to emphasize the importance of reducing dependence on foreign energy supplies, presenting renewable energy investment as an industrial and strategic response. Moeve Chief Executive Maarten Wetselaar similarly argued that domestic production could strengthen European energy resilience while supporting industrial competitiveness. These ambitions remain dependent on commercially viable production, infrastructure development and sustained demand.
Technical and economic challenges will determine how far the initiative progresses. Green hydrogen requires substantial quantities of renewable electricity, reliable water supplies and specialized transportation and storage infrastructure. Its competitiveness also depends on production costs and the willingness of industrial customers to replace conventional hydrogen or fossil fuels. Construction represents a major milestone, but the projected environmental and economic benefits will depend on successful commissioning and subsequent commercial operation.
Onuba forms part of Moeve’s broader €2.4 billion investment program in Andalusia, which includes a second-generation biofuels facility. Hydrogen production is expected to begin in 2029, making the current construction phase an initial step rather than an immediate transformation of European energy supply. The development nevertheless reflects a wider industrial shift in which renewable electricity is increasingly being considered not only as a source of power but also as a foundation for manufacturing, transportation and energy security.
Europe’s hydrogen ambitions are moving from policy commitments toward physical infrastructure. Whether the technology achieves commercial scale will depend on the interaction between investment, industrial demand and the cost of renewable energy.
