Moeve and its strategic partners have officially broken ground on “Onuba,” the landmark 300 MW first phase of the Andalusian Green Hydrogen Valley in Huelva, Spain. Backed by a joint investment of over €1 billion and €304 million in EU-backed public funding, the facility will produce 45,000 tonnes of renewable hydrogen annually. This cornerstone project anchors a €2.4 billion regional transformation aimed at scaling Europe’s largest green molecules hub and advancing industrial decarbonization.
Huelva, Spain | September 17, 2026 – Senior political, institutional, and business leaders gathered in Palos de la Frontera, Huelva, to mark the official start of construction on Onuba, the landmark first phase of the Andalusian Green Hydrogen Valley.
Representing a joint investment of more than €1 billion, the milestone project establishes Europe’s largest renewable hydrogen hub. The event drew key figures including Spanish Prime Minister Pedro Sánchez, European Commission Executive Vice-President Teresa Ribera, and Andalusian Regional Government President Juanma Moreno Bonilla, underscoring the strategic weight of the initiative for Spain and the wider European energy landscape.
Project Scale and Strong Partnership Structure
Led by energy firm Moeve with a majority 51% stake, Onuba will feature 300 MW of initial electrolysis capacity (with an optional 105 MW expansion) and produce approximately 45,000 tonnes of renewable hydrogen annually.
The project brings together top-tier industrial and financial partners:
- Hy24: The world’s clean hydrogen private equity asset manager.
- COFIDES: Spain’s public-private finance institution.
- Enagás Renovable & Alter Enersun: Jointly holding the remaining stake to drive renewable gas and electricity generation.
The facility is expected to avoid around 250,000 tonnes of CO2 emissions annually while generating over 8,000 direct, indirect, and induced jobs across the value chain, supporting more than 400 local small and medium-sized enterprises (SMEs) and self-employed businesses.
Leadership Perspectives
Highlighting the national and continental importance of the groundbreaking, key leaders shared their vision for the transition:
Pedro Sánchez, Prime Minister of Spain, said “The Government of Spain is supporting this transformation, we have made renewable hydrogen a true national priority. Moeve’s project has received more than €300 million in public funding.”
Teresa Ribera, Executive Vice-President of the European Commission, said “The recognition of this plant as a Project of Common Interest by the EU reflects its strategic importance, The energy transition should not be viewed as a cost to industry, but as an opportunity to make it stronger, more innovative and more autonomous.”
Juanma Moreno Bonilla, President of the Regional Government of Andalusia, said “Andalusia and Spain are ready and fully equipped to play a leading role in the ‘revolution’ toward the clean energy the planet needs.”
Maarten Wetselaar, CEO of Moeve, said “Today, we are turning the page on green hydrogen pilot projects towards the chapter of large-scale construction. The Onuba project reinforces Spain’s position at the forefront of Europe’s sustainable energy production.”
Part of a €2.4 Billion Transformation Hub
Moeve is anchoring the development of Europe’s largest green molecules hub in Huelva with a total investment of €2.4 billion across Andalusia. This includes both the Onuba green hydrogen plant and a second-generation (2G) biofuels facility slated to begin producing sustainable aviation fuel (SAF) and renewable HVO diesel next year.
Designated by the European Union as a Project of Common Interest (PCI), Onuba has secured €304 million in funding from the Spanish Government through NextGenerationEU funds. Once fully realized, the broader Andalusian Green Hydrogen Valley initiative aims to scale up to 2 GW of electrolysis capacity across Palos de la Frontera (Huelva) and San Roque (Cádiz), helping green molecules play a critical role in halving Europe’s external energy dependence by 2040.
