A billion-euro moeve for hydrogen in southern Spain

March 5, 2026 |

In Spain, energy company Moeve has taken the final investment decision to begin construction of the first phase of the Andalusian Green Hydrogen Valley near Huelva, launching what the company says will be Southern Europe’s largest green hydrogen project and a new source of fuel for aviation, shipping and heavy industry.

The first phase, known as Onuba, will involve more than €1 billion in investment and is designed to produce about 45,000 tonnes of green hydrogen a year. The project will start with 300 megawatts of electrolyzer capacity and could expand by another 100 megawatts if additional grid capacity becomes available.

Moeve will hold a majority stake in the venture, with partners including Masdar and Enalter, the latter majority controlled by Enagás Renovable. The project will also include a photovoltaic plant to supply renewable electricity for hydrogen production.

The development has been designated a Project of Common European Interest by the European Commission and has received €304 million in support from the Spanish government through the European Union’s NextGenerationEU program.

The hydrogen produced is expected to supply fuels for aviation, road and maritime transport while also serving nearby chemical and fertilizer industries.
