Repsol produces renewable hydrogen using biomethane

Repsol has produced renewable hydrogen using biomethane as a raw material for the first time.

The renewable hydrogen was used to manufacture fuels with a low carbon footprint, such as petrol, diesel, or kerosene for aviation.

Ten tons of renewable hydrogen was produced at Repsol’s Cartagena Industrial Complex from 500 MWh of biomethane, preventing emissions of approximately 90 tons of CO2. The biomethane used as a raw material was obtained from urban solid waste.

Through this process, Repsol replaces conventional natural gas with biomethane of sustainable origin to produce renewable hydrogen in its industrial complexes, therefore decarbonising its processes and products. The first industrial tests carried out by Repsol will also serve as an example for developing the system of guarantees of origin for renewable gases to be implemented in Spain.
