Repsol produces hydrogen from biomethane

Firm has replaced natural gas in its industrial processes with biomethane obtained from municipal solid waste

Spanish oil and gas firm Repsol has for the first time produced low-carbon hydrogen using biomethane as a raw material at its refinery in Cartagena. The same steam methane reforming (SMR) technology used to produce grey hydrogen from natural gas can use biomethane as a natural gas substitute to provide a lower-carbon source of hydrogen. Repsol has replaced natural gas in its industrial processes with biomethane obtained from municipal solid waste. So far, the company has produced 10t of hydrogen from 500MWh of biomethane. “The production of renewable hydrogen in this way is further evidence of the transformation of Repsol's industrial complexes into multi-energy poles capable of manufacturin
