Cepsa and PreZero Spain have formed a strategic partnership focusing on decarbonization and circular economy practices. PreZero will supply biomethane to Cepsa, and both companies will work on developing biomethane plants and recovering waste for second-generation biofuels and circular chemical products. The alliance aims to decarbonize the land fleet operated by PreZero in Spain and Portugal. A biomethane plant in Huelva is being developed, with plans to produce green hydrogen and renewable fuels, contributing to the energy transition. PreZero, a major biomethane producer in Spain, will provide Cepsa with renewable gas to reduce CO2 emissions and support industrial decarbonization. The partnership also involves the treatment of organic waste, cooking oils, and plastic waste for biofuel and circular chemical product production. Cepsa's 2030 strategy, Positive Motion, focuses on green molecules like renewable hydrogen, 2G biofuels, and sustainable diesel. PreZero aims to be carbon neutral by 2050, emphasizing sustainability and energy efficiency measures. The initiative aligns with SDGs, including affordable and clean energy, decent work, responsible consumption, and climate action.
