Moeve Begins Construction of the 300 MW Green Hydrogen Plant in Huelva

Moeve has begun construction of the first phase of the Andalusian Green Hydrogen Valley in Palos de la Frontera (Huelva), considered by the company to be the largest project of its kind in Europe. The first plant, named Onuba, will initially have 300 MW of electrolysis capacity and will involve an investment of over 1 billion euros.

The project will have a significant economic and labor impact during its development, construction, and commissioning phases. According to Moeve, it will generate more than 8,000 direct, indirect, and induced jobs and will contribute to the activity of over 400 SMEs and self-employed workers in the area.

Moeve leads this first phase with a 51% stake. Among the project partners are Hy24 and COFIDES, which together hold 29%, while the remaining 20% is held by Enagás Renovable and Alter Enersun.

The plant will have the capacity to produce approximately 45,000 tons of renewable hydrogen per year and, according to the company's forecasts, will help avoid the emission of about 250,000 tons of CO₂ annually. The hydrogen produced can be used to manufacture more sustainable fuels for road transport, aviation, and the maritime sector, as well as to reduce emissions from other industries.

Onuba will also incorporate various digital technologies from its design, such as a digital twin, a unified data platform, and IoT systems. These tools will be aimed at improving the efficiency, safety, and control of the facility's operations.

The first phase of the project has been recognized by the European Union as a Project of Common Interest and has received 304 million euros in public funding granted by the Government of Spain through the Recovery, Transformation and Resilience Plan and the NextGenerationEU funds.

The Andalusian Green Hydrogen Valley aims to reach 2 GW of electrolysis capacity between Moeve's facilities in Palos de la Frontera and San Roque (Cádiz). The company believes that the availability of port infrastructure, land, and renewable resources makes Andalusia a strategic area for the production of hydrogen and other green molecules intended, among other uses, for maritime transport.
