Energy company Moeve has started construction of a 300 MW green hydrogen plant in Spain that will supply renewable hydrogen for lower-carbon fuels, including for shipping.

The Onuba project in Palos de la Frontera, Huelva, represents an investment of more than €1 billion, the firm said in a press release on Thursday. 

Moeve holds a 51% stake, while Hy24 and Spain's public-private finance institution COFIDES hold a combined 29%. Enagás Renovable and Alter Enersun own the remaining 20%.

The plant is expected to produce around 45,000 mt/year of renewable hydrogen and avoid about 250,000 tonnes of CO2 emissions.

The hydrogen will support the production of lower-carbon fuels for road, aviation and maritime transport, as well as other industrial uses.

Onuba has been designated a Project of Common Interest by the European Union and has secured €304 million in Spanish government funding under the NextGenerationEU-backed recovery plan.

The wider Andalusian Green Hydrogen Valley is planned to reach 2 GW of electrolysis capacity across Huelva and San Roque, Cádiz.
