Spanish oil and gas giant Repsol has produced its first batch of hydrogen utilising biomethane as the feedstock.
Repsol confirmed Monday it had produced 10 tonnes of renewable hydrogen at its Cartagena Industrial Complex, in the Murcia region of south-east Spain.
The hydrogen produced from the process will be used to manufacture fuels such as gasoline, diesel, or kerosene for aviation.
By utilising the equivalent of 500 megawatt hours of biomethane to produce the hydrogen, Repsol claims it avoided roughly 90 tonnes of carbon dioxide emissions.
“This new process for production of renewable hydrogen is further evidence of the transformation of Repsol’s industrial complexes into multi-energy hubs capable of manufacturing decarbonized products. It also supports the company’s commitment to achieving zero net emissions by 2050,” Repsol said in Monday’s statement.
“Energy efficiency, circular economy, renewable hydrogen, and CO2 capture and use technologies are the four main pillars on which Repsol is based to place its industrial complexes at the forefront of the energy transition.”
The milestone comes after Repsol in August claimed to have produced Spain’s first aviation biofuel from waste at its Petronor Industrial Complex in Bilbao.
It claimed the 5300-tonne batch of biojet would help avoid 300 tonnes of CO2, roughly the equivalent emitted from 40 flights between Madrid and Bilbao.
Repsol is also planning to start up a 2.5-megawatt electrolyser at its Petronor refinery in the second half of next year to produce green hydrogen, while it is aiming to have 1.9 gigawatts of installed capacity across its portfolio by 2030.
