Spanish energy company Moeve has started construction of a green hydrogen project in Andalusia that it says will be the largest of its kind in Europe.
First Phase Exceeds €1 Billion
The first phase, known as Onuba, will begin with 300 MW of electrolysis capacity, with an option to add another 105 MW. Total investment exceeds €1 billion, including infrastructure and a photovoltaic plant for self-consumption.

Moeve expects the project to create more than 8,000 direct jobs during development, construction and commissioning, while supporting more than 400 small and medium-sized enterprises and local self-employed workers.
Spain Expands Green Hydrogen Production
“Today we are turning the page on pilot green hydrogen projects and entering the chapter of large-scale construction,” Moeve CEO Maarten Wetselaar said.
He said Spain’s solar and wind resources and available land could support large-scale renewable power production and reduce reliance on imported energy.
Onuba is expected to produce about 45,000 tonnes of renewable hydrogen annually and avoid roughly 250,000 tonnes of CO₂ emissions each year. The output will support lower-carbon fuels for road, aviation and maritime transport, as well as other industrial processes.
EU And Spanish Support
Construction began in Palos de la Frontera on Thursday at an event attended by Spanish and European officials, including Prime Minister Pedro Sánchez and European Commission Executive Vice-President Teresa Ribera.
Moeve holds a 51% stake, Hy24 and Cofides jointly own 29%, and Enagás Renovable and Alter Enersun hold the remaining 20%.
The EU has designated Onuba a Project of Common Interest, while the project has received €304 million from Spain’s Recovery, Transformation and Resilience Plan, financed through NextGenerationEU.
Onuba Is First Phase Of 2 GW Plan
Onuba is the first phase of Moeve’s Andalusian Green Hydrogen Valley, which the company plans to expand to 2 GW of electrolysis capacity across sites in Palos de la Frontera and San Roque, Cádiz.
Moeve also plans to connect Huelva with European industrial centers through pipeline and maritime routes. Its broader Andalusian energy transition program includes €2.4 billion of planned investment, including a second-generation biofuels plant for sustainable aviation fuel and renewable diesel.
