Spanish energy company Repsol has announced the successful production of 100% renewable petrol (also called ePetrol, eFuel, synfuel, synthetic fuel) at an industrial scale — a milestone that underlines the growing potential of Power-to-X technologies to accelerate the energy transition.
Repsol already operates the Iberian Peninsula’s first large-scale renewable fuels plant in Cartagena, producing sustainable aviation fuel (SAF) and renewable diesel, using a combination of renewable hydrogen and biogenic CO₂.. A second facility, with a capacity of 200,000 tonnes per year, is due to start operations in Puertollano in 2026.
This ePetrol process results in a drop-in fuel that can be used in existing vehicles without any engine modification, offering an immediate path toward defossilized mobility.
The new Nexa 95 100% renewable petrol, Repsol’s highest-quality 95-octane product, is already available in 20 service stations across Madrid and Catalonia and will reach 30 stations nationwide — including Valencia, Zaragoza, and Bilbao — by year-end. The fuel can be used in any petrol-powered vehicle without modification, cutting net CO₂ emissions by more than 70% compared to conventional petrol.
According to Repsol, the new petrol has the same quality and performance as its fossil-based equivalent but reduces lifecycle CO₂ emissions by up to 90%. The company plans to scale up production in the coming years as part of its strategy to reach net-zero emissions by 2050.
This development illustrates how Power-to-X — the conversion of renewable electricity into synthetic fuels, chemicals, or other energy carriers — can complement electrification and help decarbonize sectors that are difficult to electrify directly. By combining renewable hydrogen with captured CO₂, companies like Repsol are creating sustainable molecules that integrate seamlessly into today’s energy system.
As international collaboration and investment in Power-to-X continue to grow, projects like Repsol’s show how Europe is moving toward a more flexible, technologically neutral, and defossilized energy future.

Slight correction:
Your title should not say Repsol is making ePetrol — they are making eDiesel (and sustainable aviation fuel, or SAF). In fact, your article says “…producing sustainable aviation fuel (SAF) and renewable diesel”.
Petrol (gasoline) is used in spark-ignition engines, while diesel is used in compression-ignition engines.
Thank you for your comment. Actually, both is correct. The news is that they produce ePetrol. eSAF and eDiesel is what they have been producing for a while already. Sorry, if the wording is misleading.
