Moeve begins construction of its Andalusian Green Hydrogen Valley

September 24, 2026 |

In Spain, Moeve has celebrated the start of construction of the first phase of the Andalusian Green Hydrogen Valley, Europe’s largest renewable hydrogen project, with an event in Palos de la Frontera, Huelva, that brought together senior representatives from the Spanish Government, the European Commission, the Regional Government of Andalusia, the municipalities of Palos de la Frontera and Huelva, as well as business leaders involved with and supporting the project. Their presence underscored the strategic importance of this pioneering initiative, which aims to help establish a new renewable hydrogen market and position Spain at the forefront of the sector globally.

“Onuba” is the name for the first phase of the Andalusian Green Hydrogen Valley. Located at Moeve’s Energy Park in Palos de la Frontera (Huelva), Onuba will have an initial 300 MW of electrolysis capacity, with the option to expand by an additional 105 MW. The project represents a joint investment of more than €1 billion, including associated infrastructure and the development of a dedicated photovoltaic plant for self-consumption. During the development, construction and commissioning phases, it is expected to generate more than 8,000 direct, indirect and induced jobs across the value chain and support the economic activity of more than 400 local SMEs and self-employed businesses.

The project, led by Moeve with a majority 51% stake, benefits from a strong shareholder structure that combines industrial and financial expertise through the participation of Hy24, the world’s largest clean hydrogen private equity asset manager, and COFIDES, Spain’s public-private finance institution, as strategic partners with a combined 29% stake. The remaining 20% is jointly held by Enagás Renovable, one of Europe’s leading developers of renewable gas projects, and Alter Enersun, a company dedicated to the development of renewable electricity generation facilities.

The facility will be capable of producing approximately 45,000 tons of renewable hydrogen annually, avoiding around 250,000 tons of CO2 emissions each year, equivalent to the emissions generated by the internal combustion vehicle fleets of the cities of Huelva, Cádiz and Jaén.1 The hydrogen will be used to support the more sustainable production of fuels for road, aviation and maritime transport, while also helping to decarbonize other industries.
