Spain-headed oil, gas, and multi-energy major, Repsol S.A. (Repsol), has recently presented its renewable hydrogen strategy, a roadmap for the company to become the market leader in the Iberian Peninsula and become the third-largest producer in Europe. The company’s new Hydrogen Director, Tomás Malango, gave an overview of the projects and initiatives that the company will deploy throughout the renewable hydrogen value chain, with an investment of EUR 2.549 billion until 2030.


According to the company, renewable hydrogen is one of the key pillars in its decarbonization strategy, and the company plans to use different technologies to reach a capacity of 552 MW equivalent in 2025 and 1.9 GW in 2030.

Repsol is currently the leading producer and consumer of hydrogen in Spain, using it as a raw material in its industrial processes, to manufacture a multitude of essential products for mobility, construction, healthcare, and agriculture, among others.

Firm commitment and technology leadership

Repsol is undergoing a transformation process, moving forward in the evolution of its industrial complexes into multi-energy hubs capable of manufacturing products with a low, zero, or even a negative carbon footprint thanks to the use of sustainable raw materials, such as different types of waste, as well as the application of more efficient and decarbonized processes.

To achieve this, Repsol says that it will “employ all available technologies and develop those that allow for an accelerated energy transition at the lowest possible cost.”

Repsol has already announced that it will install electrolyzer plants at its industrial complexes. On September 20, 2021, Repsol announced that it will install the first electrolyzer at its Petronor refinery in Bilbao.

With a capacity of 2.5 MW, the plant will enter into operation in the second half of 2022, and it will supply both the refinery and facilities at the Left Bank Technology Park, located in the nearby municipality of Abanto y Zierbena.

The Petróleos del Norte (Petronor) refinery, located in Múskiz, near Bilbao northern Spain has a refining capacity of 220 000 barrels per day. Repsol is installing its first electrolyzer in the Basque Country in the second half of 2022, to produce renewable hydrogen at its Petronor refinery. The facility will have a capacity of 2.5 MW and will involve an investment of EUR 8.9 million, covering also the construction of the necessary infrastructures for the use and distribution of the renewable hydrogen produced (photo courtesy Petronor).

The company has also announced the installation of other electrolyzer plants in the vicinity of its industrial sites. Among the projects already announced are the 100 MW electrolyzers to be located at the Cartagena, Tarragona, and Petronor refineries.

The company will also build a 10 MW electrolyzer, together with Enagás and the regional Basque Energy Agency (EVE), to produce renewable hydrogen for the synthetic fuels plant to be installed in the Port of Bilbao.

Hydrogen from biomethane and solar-to-X

Additionally, the company is adapting its conventional hydrogen production infrastructures to obtain renewable hydrogen from biomethane, using different circular economy technologies, among others. In this way, it will be able to produce hydrogen from organic waste from different sources, such as urban solid waste, biomass, or by-products from the agricultural and livestock industries.

Repsol has recently carried out the first tests in this regard at its Cartagena refinery, where it has manufactured low carbon footprint fuels using renewable hydrogen.

Repsol has also been working on photo electro-catalysis technology for more than a decade. The main advantage of this technology over current solutions is that only water and sunlight are needed as raw materials to produce 100 percent renewable hydrogen.
