Owned by Abu Dhabi fund Mubadala and the Carlyle Group (CG.O), opens new tab, Cepsa is investing up to 8 billion euros ($8.6 billion) through 2030 to shift its business toward low-carbon fuels, such as green hydrogen and biofuels.
The companies said on Tuesday they will together develop plants to produce biomethane from organic waste. The first such plant will have a capacity of up to 100 GWh and will feed Cepsa's planned green hydrogen and biofuels facilities around Huelva, in southern Spain.
Under the deal, PreZero will also supply biomethane to Cepsa, and, among other initiatives, the companies will team up to recover organic waste to produce biofuels.
"This alliance with PreZero will allow us to expand access to circular raw materials to produce alternative energies that will facilitate the energy transition, such as green
hydrogen and second-generation biofuels," Carlos Barrasa, executive vice president of commercial & clean energies at Cepsa, said.
Biofuels are seen as essential in decarbonising transportation, such as aviation, which is hard to electrify. Second-generation biofuels are made from non-food organic materials such as wood and agriculture waste, as opposed to the first-generation ones made from sugar-starch or oilseed crops.
