Hydrogen, the ally for decarbonisation | The weekly country

Achieving new energy technologies that reduce C02 emissions has gone from being a wish to becoming a necessity. In this search, hydrogen has become an ally that offers more and more possibilities. Through techniques such as electrolysis, which separates water molecules into hydrogen and oxygen using renewable electrical energy, this element is obtained without producing emissions. For that reason, hydrogen is an alternative to achieve the decarbonization of both industrial activities and for the daily life of citizens.

Repsol, a company that has made a commitment to achieve net zero emissions by 2050, is the main producer and consumer of this energy source in Spain, with almost 60% of total demand. “Renewable hydrogen represents for Spain the greatest opportunity for industrialization and energy relevance that we have ever faced,” says Tomás Malango, Repsol’s Director of Hydrogen.

Among the different projects of the company with this element as a key to the energy transition is the generation of hydrogen from biogas from waste, while in 2022 a project will be launched in the industrial complex of Petronor in the Basque Country for the distribution of renewable hydrogen. In the same way, it explores other ways to obtain renewable hydrogen efficiently, such as photoelectrocatalysis, which converts sunlight into hydrogen through a catalyst and water, without using electricity.


As Malango predicts, “we will begin to see renewable hydrogen available in 2022 on a small scale and, in the next 10 or 15 years there should be an increase in its consumption. We have a historic opportunity to build a new renewable value chain, based on our strengths and technological capabilities. We have to turn this opportunity into an industry development capable of generating quality employment for Spain ”.

Zero emissions target

Repsol’s goal is to achieve zero emissions by 2050. To do this, it increases investment between 2021 and 2025 to 19.3 billion euros, of which 35% will be dedicated to increasing its renewable electricity generation, hydrogen and other decarbonization projects.
