The start of construction makes the Andalusian Green Hydrogen Valley into one of the largest industrial projects currently under construction in Spain.
The first phase of the Andalusian Green Hydrogen Valley — Onuba — is already underway and will have an electrolysis capacity of 300 MW, expandable by an additional 105 MW. With a joint investment of over €1 billion, Onuba will generate an impact equivalent to more than 8,000 direct, indirect, and induced jobs across the entire value chain during the various stages of the project.

A robust ecosystem of partnerships
The Onuba project, led by Moeve with a majority stake (51%), has a solid ownership structure that combines industrial and financial expertise thanks to the inclusion of Hy24—the world’s largest fund specializing in renewable hydrogen—and COFIDES, the Spanish public-private financial institution, as strategic partners. It also includes a joint stake held by Enagás Renovable, one of Europe’s leading developers of renewable gas projects, and Alter Enersun, a company dedicated to developing renewable electricity generation facilities.
A project supported by Europe
This first phase of the Andalusian Green Hydrogen Valley has been recognized by the European Union as a Project of Common Interest (PCI) and has secured funding of €304 million granted by the Government of Spain under the Recovery, Transformation and Resilience Plan, financed by the European Union through NextGenerationEU, as part of the support program for Renewable Hydrogen Valleys for the development of 405 MW of the Andalusian Green Hydrogen Valley.
This institutional support is recognition of the project's strategic contribution to European energy security and industrial competitiveness, as well as the decarbonization of sectors that are difficult to electrify.

Technology for a new industry
Onuba is conceived as our first digital native plant. From the design phase, it has incorporated a digital twin and an integrated data and IoT platform that will enable us to optimize operations, foresee incidents, and maximize energy and operational efficiency.
Digitalization will be a key factor in developing a new generation of industrial assets that are safer, more efficient, and ready to scale up renewable hydrogen production in Europe.
An opportunity for Andalusia
-
-
The Andalusian Green Hydrogen Valley will help turn Andalusia and Spain into a European energy powerhouse, contributing to supply security and energy independence in Europe, thus supporting the REPowerEU strategy to drive forward the energy transition and contributing to the decarbonization objectives.
-
The project will also help consolidate Andalusia's position as one of Europe's leading industrial centers for green molecules, boosting local economic activity, attracting international investment, and strengthening the region's business community.
-
Along with the new 2G biofuel plant in Palos de la Frontera, the construction of the Andalusian Green Hydrogen Valley will create Europe’s largest green molecule energy hub in Huelva.
