Cepsa, Enagas and Enersun develop green hydrogen plant in Spain

Cepsa, Enagás Renovable and Alter Enersun have agreed to collaborate on the development of a green hydrogen plant in Huelva, linked to a solar power plant, as part of the Andalusian Green Hydrogen Valley.

When it becomes operational in 2026, the new green hydrogen plant, whose electrolysis capacity will be 200 MW, will be able to produce advanced biofuels while also supplying Cepsa’s own industrial needs. A 200 MW capacity will also be provided by the photovoltaic project.

Cepsa and Enagás Renovable will be in charge of building and commissioning the hydrogen plant at the Cepsa Energy Park facilities in Palos de la Frontera, and Alter Enersun will be in charge of developing the photovoltaic plant, which will be situated on land owned by the Port Authority of Huelva in the country’s capital city.

The production of renewable energy close to the location where it will be used results in significant project optimization and better utilization of company synergies.

Biomethane agreement

Additionally, a related deal for the production and acquisition of biomethane has been inked by Cepsa and Enagás Renovable. In a number of industrial operations, biomethane will take the place of natural gas, lowering the amount of CO2 emitted.

Through a biogas upgrading process, biomethane, a renewable gas with properties akin to those of natural gas, is produced. The latter is created through the anaerobic digestion of organic waste, a natural process that speeds up the creation of this environmentally friendly gas with a high concentration of methane. This is made possible by the action of bacteria that can survive without oxygen.

The partnership between Cepsa, Enagás Renovable, and Alter Enersun supports several of the Sustainable Development Goals (SDGs) of the 2030 Agenda, including SDGs 7 (Affordable and Clean Energy), 8 (Decent Work and Economic Growth), 12 (Responsible Consumption and Production), and 13 (Responsible Consumption and Production) (Climate action).
