Renewable hydrogen

Renewable hydrogen as a source of energy

Using renewable hydrogen along with low-carbon liquid fuels is vital for decarbonization. Therefore, we continue to focus on developing technology solutions at Repsol aimed at producing low-carbon hydrogen that will enables us to keep advancing towards the energy transition.

What is renewable hydrogen?

Renewable hydrogen is an energy vector derived from renewable sources that releases zero CO2 emissions. It is mainly produced thanks to water electrolysis, which is a process involving the separation of the water molecule in hydrogen and oxygen by applying renewable electric energy. Additionally, there are other ways to obtain this energy including gasification, using biomass, and to a lesser extent photoelectrocatalysis.

Main uses of hydrogen

Renewable hydrogen will be used to produce synthetic fuels, conventional fuels, and in the long term it can also be used to supply the demand for hydrogen in the mobility industry. Once all its potential applications have been rolled out, it is estimated that renewable hydrogen could represent 10% to 20% of the world's energy consumption.
