Spanish energy major Moeve on Thursday (17 September) said it has celebrated the start of construction of the first phase of the Andalusian Green Hydrogen Valley, Europe’s largest renewable hydrogen project, with an event in Palos de la Frontera, Huelva. “Onuba” is the name for the first phase of the Andalusian Green Hydrogen Valley. Located at Moeve’s Energy Park in Palos de la Frontera (Huelva), Onuba will have an initial 300 MW of electrolysis capacity, with the option to expand by an additional 105 MW. “The project represents a joint investment of more than EUR 1 billion, including associated infrastructure and the development of a dedicated photovoltaic plant for self-consumption,” the company said.. The project, led by Moeve with a majority 51% stake, benefits from a strong shareholder structure that combines industrial and financial expertise through the participation of Hy24, the world’s largest clean hydrogen private equity asset manager, and COFIDES, Spain’s public-private finance institution, as strategic partners with a combined 29% stake. The remaining 20% is jointly held by Enagás Renovable, one of Europe’s leading developers of renewable gas projects, and Alter Enersun, a company dedicated to the development of renewable electricity generation facilities. The facility will be capable of producing approximately 45,000 metric tonnes (mt) of renewable hydrogen annually, avoiding around 250,000 mt of CO2 emissions each year, equivalent to the emissions generated by the internal combustion vehicle fleets of the cities of Huelva, Cádiz and Jaén. The hydrogen will be used to support the more sustainable production of fuels for road, aviation and maritime transport, while also helping to decarbonise other industries. The new plant will deploy advanced technological solutions that will help shape the emerging hydrogen market while redefining energy engineering standards as the company’s first digitally-native facility.
