October 13, 2025 [Oil Price]- Spanish energy company Repsol announced it has achieved industrial-scale production of gasoline derived from 100% renewable sources at its complex in Tarragona, Spain, according to a company press release.

The new fuel, branded Nexa 95 Gasoline of 100% renewable origin, is compatible with existing gasoline vehicles without engine modifications and reportedly reduces net carbon dioxide (CO2?) emissions by more than 70% compared to conventional gasoline.

The fuel is currently available at 20 service stations in Spain, primarily in the Madrid and Catalonia regions. Repsol expects to expand availability to 30 stations by the end of the year, including locations in Tarragona, Valencia, Zaragoza, and Bilbao. The company is adding the renewable gasoline to its existing lineup of renewable fuels, which includes a 100% renewable diesel product.

The development marks a step in the ongoing efforts by refiners to decarbonize the transportation sector using existing vehicle infrastructure. Repsol highlighted the significance of renewable liquid fuels, noting that combustion engine vehicles—gasoline, diesel, and hybrid—represent 97% of the Spanish and European vehicle fleets.

The company also used the announcement to address the proposed European Union (EU) regulation on CO2? emission standards, which includes a potential ban on the sale of new combustion engines by 2035. Repsol suggested that the role of 100% renewable fuels should be re-evaluated within the EU’s climate targets.

The press release SUGGESTS that the uncertainty created by the potential ban has contributed to the aging of Spain’s vehicle fleet, which has an average age of 14.5 years. Repsol stressed the need for long-term targets and a favorable tax framework for renewable fuels to drive investment, similar to policies already in place for the aviation and maritime sectors.

Repsol’s industrial process in Tarragona, which resulted from over 20 years of research, was developed in collaboration with Honeywell. The company’s strategy for decarbonizing mobility involves a combination of solutions, including electrification, renewable hydrogen, and renewable fuels.

Repsol is already operating a large-scale plant in Cartagena, Spain, focused exclusively on producing sustainable aviation fuel (SAF) and renewable diesel. A second plant is scheduled to open at its Puertollano complex in 2026 with an annual capacity of approximately 200,000 tons of renewable fuel for road and maritime transport.

Repsol has established supply agreements for renewable fuels with several heavy-duty transport, passenger transport, and maritime operators across Spain and Portugal, including Scania, Alsa, and Royal Caribbean, in addition to agreements with commercial airlines such as Iberia and Ryanair for sustainable aviation fuel.
