Cepsa and Fertiberia, two of Spain's largest hydrogen consumers, have reached an agreement to decarbonize their production processes by jointly developing a large-scale renewable hydrogen plant in Huelva using green energy and other renewable gases. The companies will also implement other industrial synergies between their Huelva sites. Through this union, Cepsa and Fertiberia have become strategic partners in the project to develop 1 GW of electrolysis capacity in Palos de la Frontera as part of the Andalusian Green Hydrogen Valley.This valley will have a 2 GW capacity 1 GW in Campo de Gibraltar (Cádiz) and another in Palos de la Frontera (Huelva)—and production of up to 300,000 tons in Cepsa's Energy Parks.The agreement will meet the hydrogen and biogenic CO2 needs of both companies’ facilities in the industrial fabric of Palos de la Frontera (Huelva) in the most optimal way. Green hydrogen production will begin in 2026, and it will be used for Cepsa's and Fertiberia's own industrial consumption while enabling the manufacture of advanced biofuels, ammonia, AdBlue and sustainable crop nutrition solutions.Cepsa's La Rábida Energy Park is adjacent to Fertiberia's facilities in Palos de la Frontera. Therefore, the partnership will help to leverage all existing industrial and operational synergies between the two sites, allowing them to be managed as efficiently as possible.
