Enagás Renovable and Alter Enersun, new Cepsa allies in the Andalusian Green Hydrogen Valley

25 de January de 2023

  • The three companies signed an agreement for the joint development of a green hydrogen plant and an associated 200 MW photovoltaic power project in Huelva.
  • In addition, Cepsa and Enagás Renovable have signed a complementary agreement for the production and purchase of biomethane. 
  • The synergies of the three energy companies will boost the decarbonisation of Huelva’s industry and heavy land, air, and sea transport. 
  • The Andalusian Green Hydrogen Valley is the largest green hydrogen project in Europe, with a capacity of 2 GW and a production of up to 300,000 tonnes.

Cepsa, a global energy company committed to sustainable mobility and energy, Enagás Renovable, one of the largest European promoters of renewable gas projects, and Alter Enersun, a company dedicated to the promotion of renewable electricity generation facilities, have signed an agreement to develop a green hydrogen plant in Huelva, connected to a solar power plant, as part of the Andalusian Green Hydrogen Valley.  

The new green hydrogen plant, whose electrolysis capacity will reach 200 MW, will be operational in 2026 and its production will be used to supply Cepsa’s own industrial consumption, enabling the manufacture of advanced biofuels. The photovoltaic facility will also have a capacity of 200 MW. 

Alter Enersun will be in charge of developing the photovoltaic plant, which will be located on land belonging to the Port Authority of Huelva, and Cepsa and Enagás Renovable will be responsible for the construction and start-up of the hydrogen plant at the Cepsa Energy Park facilities in Palos de la Frontera. 

The production of renewable energy close to where it will be consumed means an important optimisation of the projects and a better use of synergies between the companies.  

Representatives of the three companies presented the partnership this morning at La Rábida Energy Park, accompanied by Carmelo Romero, Mayor of Palos de la Frontera; Bella Verano, Government Delegate of the Andalusian Regional Government in Huelva; Gabriel Cruz, Mayor of Huelva; Pilar Miranda, Chairperson of the Port of Huelva; and José Luis Menéndez, Chairperson of AIQBE. 

According to Joaquín Rodríguez, Cepsa’s Director of Hydrogen: “We are adding two new allies to the Andalusian Green Hydrogen Valley to decarbonise Huelva’s industry and thus promote its sustainability and competitiveness. We are combining our technical capabilities, experience, and knowledge of the sector with those of Enagás Renovable and Alter Enersun to start up a large-scale green hydrogen plant, which will be self-sufficient in renewable energies.” 

Luis Iglesias, COO of Enagás Renovable, expressed his satisfaction with this collaboration between the three companies “which allows progress to be made in the promotion of renewable gas projects in Spain, responding to the decarbonisation needs of industry and the transport sector in its different forms.” 

José Luis Morlanes, CEO of Alter Enersun, highlighted that “we are going to build a 200 MW photovoltaic plant to generate green hydrogen that will harness the sun’s energy to improve the environment. We are proud to participate in Cepsa’s Positive Motion strategy, which contributes to the energy transition and to achieving energy autonomy in Spain.”

Biomethane, an ally that contributes to decarbonisation 

Cepsa and Enagás Renovable have also signed a complementary agreement for the production and purchase of biomethane. Biomethane will be used to replace natural gas in various industrial processes, thus contributing to a reduction of CO2 emissions.   

Enagás Renovable and Alter Enersun, new Cepsa alliesBiomethane, a renewable gas with similar characteristics to natural gas, is obtained through a biogas upgrading process. Biogas is obtained through the anaerobic digestion of organic waste, a natural process that speeds up the production of this ecological gas that has a high concentration of methane, thanks to the action of bacteria that can live in an oxygen-free environment.  

Collaboration between companies is key to energy transition 

This new alliance is part of Cepsa’s 2030 Positive Motion strategy, through which the company is transforming itself to become a benchmark in the energy transition, becoming a leader in sustainable mobility in Spain and Portugal, as well as producing renewable hydrogen and advanced biofuels. Cepsa will promote the decarbonisation of its customers, as well as its own activity, reaching net zero emissions by 2050. 

Enagás Renovable considers collaboration between companies to be a pillar of its corporate strategy to promote the development of renewable gases and contribute to achieving a carbon-neutral economy. Enagás Renovable is thus committed to an energy model that discontinues the use of fossil fuels and makes the use of renewable energy sources widespread, helping to protect the environment and people.  

Alter Enersun is developing competitive energy solutions that combine renewable energies with the production of green hydrogen to decarbonise energy-intensive activity, reducing emissions and dependence on fossil fuels. 

The partnership between Cepsa, Enagás Renovable and Alter Enersun contributes to several of the Sustainable Development Goals of the 2030 Agenda: SDG 7 (Affordable and clean energy), SDG 8 (Decent work and economic growth), SDG 12 (Responsible production and consumption) and SDG 13 (Climate action).
