What are biofuels?

These fuels are derived from renewable sources and release CO2 when burned. These fuels' net CO2 emissions are considered zero given that they're offset by the CO2 that's absorbed by renewable energy sources, the origin of biofuels.

At the forefront of biofuel development

As part of our commitment to becoming a net zero emissions company by 2050, we contribute to reducing CO2 emissions by producing biofuel and studying different industrial processes like the generation of hydroelectric power, fermentation, and pyrolysis for transforming waste into clean fuels.
  • 20+ years incorporating biofuels into our range of fuels.

  • 90% savings
    in emissions versus other fuels.

  • 2.8 Mt of CO2 in emissions reduction to the atmosphere in 2019.

  • 600,000 t/year in high-quality biofuel production in 2030.

  • What are the advantages of these fuels?

    Carbon-neutral fuels can be used in all existing vehicles, taking advantage of the current infrastructure without the need to develop new technology solutions or renew a fleet. Additionally, it enables us to decarbonize industries that are difficult to electrify such as maritime, aviation, and heavy-duty transportation.

4Refinery: biofuels from biomass

Together with 7 other European companies and technological centers, we participate in 4REFINERY, a European Union project that aims to develop new methods for producing advanced biofuels through technologies like hydrothermal liquefaction and rapid pyrolysis.

Rewofuel: Converting plant waste into biofuels

We participate in Rewofuel, a European Union project that aims to demonstrate the technical, environmental, and socioeconomic viability of transforming residual soft-wood into biofuels through the process of hydrolysis.
  • Microalgae: The new generation of biofuels

    The growing demand for biofuels cannot be met with only those sources extracted from land. Experts expect that the large majority of biokerosene fuels for aviation will come from algae. That's why Repsol is also committed to 3rd generation biofuels like microalgae, which are living plant systems that grow quickly, produce more oil, and benefit greatly from sunlight.
