The Onuba phase of the Andalusian Green Hydrogen Valley is set to move into construction in the coming weeks following Moeve’s final investment decision. At 300 MW, Onuba is described as the largest green hydrogen project in Southern Europe, with an option to expand by an additional 100 MW.
The first phase involves a total global investment of more than €1 billion, including associated infrastructure and development of a self-consumption photovoltaic plant. Moeve leads the project with a 51% majority stake, alongside minority participation from Masdar and Enalter, which is majority owned by Enagás Renovable.
“This decision to launch Southern Europe’s largest green hydrogen plant marks a defining step in Moeve’s Positive Motion transformation strategy,” said Maarten Wetselaar, CEO of Moeve. “Onuba will anchor a world-class hub for green molecules in Spain, supplying renewable fuels to hard-to-abate sectors while reinforcing Europe’s energy and industrial resilience. By partnering with other leaders in renewable energy, we are creating an ecosystem to build at scale.”
“As an early mover in this sector, we have long recognized green hydrogen’s role in decarbonizing hard-to-abate sectors,” said Mohamed Jameel Al Ramahi, Chief Executive Officer of Masdar. “This partnership, under the leadership of Moeve, reflects our strategy of advancing commercially viable green hydrogen projects in markets where demand is clear. We are also pleased to be advancing our support for Spain’s clean energy ambitions.”
“The Onuba project represents a significant step forward for the development of green hydrogen in Spain,” said Antón Martínez, CEO of Enagás Renovable. “At Enagás Renovable we continue to support projects that drive energy independence, foster new industrial opportunities and contribute to job creation. The Andalusian Green Hydrogen Valley is a clear example of how collaboration between companies and institutions can accelerate decarbonization while generating long-term economic and social value.”
The initiative has been designated as a Project of Common European Interest by the European Commission and has received €304 million from the Government of Spain under the Recovery, Transformation and Resilience Plan, financed by the European Union’s NextGenerationEU program, through the Hydrogen Valleys scheme, for the development of 400 MW of the Andalusian Green Hydrogen Valley.
At 300 MW, Onuba is expected to produce around 45,000 tonnes of green hydrogen per year and avoid about 250,000 tonnes of CO₂ annually. The project’s additional 100 MW is subject to obtaining additional grid capacity and board approval.
The project’s green hydrogen is intended for aviation, road, and marine transport fuels, and to supply energy for decarbonizing the chemical and fertilizer industries.
