The central debate surrounding biofuels is not about their necessity and the need for the pressure valves, tanks and infrastructure surrounding them, but more about where and how they will be used in industry sectors where it is impossible to rely on other zero-emissions fuels.
Whilst the natural focus has been on aviation and shipping, both sectors where complete electrification is currently impossible, biofuels also help to preserve sports and entertainment which cannot be electrified without fundamentally changing their function and purpose.
One of the best examples of the latter can be seen in Formula 1, which announced that it had reduced its carbon footprint by 35 per cent and was on track to reach net zero carbon emissions in the next four years.
This is, by itself, an exceptional achievement, but what makes this even more impactful is the context in which this has been achieved, and how it continues the journey towards a greener motorsport, something that was laughed at when first attempted 20 years ago.
To celebrate how far F1 and motorsport as a whole have come, it is worth exploring how F1 achieved its decarbonisation, as well as connecting it to the earliest days of biofuel-powered motorsport.
How Have Biofuels Helped Formula 1 Decarbonise?
To provide clarity, Formula 1 has pledged to make itself a net-neutral motorsport, meaning that it produces no carbon emissions throughout the season by offsetting the inevitable exhaust emissions through carbon capture, green initiatives and the reduction of fuel usage.
There are various ways in which this is achieved throughout the F1 ecosystem, which incorporates not only the biofuel used on race weekends but every aspect of production, manufacturing and transportation.
Greener Travel
Since 2018, when that pledge was made, F1 has reduced travel emissions by 21,000 tCO2e, which is 27 per cent lower than 2018.
This is due to focusing on a holistic approach to low-carbon fuel solutions, with not only lorries that rely on biofuel and hybrid engines, but also investments in sustainable aviation fuel and sustainable maritime fuel.
As air travel and sea freight are amongst the biggest contributors to carbon emissions in the world, reducing the emissions of major freight is a major factor towards decarbonising F1, with implications that affect other industries.
Greener Factories
Whilst not entirely related to fossil fuels, factories and other race facilities such as the paddock workstations required for race weekends have been significantly decarbonised.
The emissions have fallen by 37,000 tCO2e, which is a massive 64 per cent reduction compared to 2018, which illustrates the decarbonisation potential found in the significant factories and their highly intensive design and manufacturing processes.
Trackside Benefits
Alternative energy solutions have become particularly common throughout the race paddock, including solar power, battery storage systems and HVO-derived biofuel.
HVO, or Hydrotreated Vegetable Oil, is a biofuel derived from waste animal fats and food oils, which creates a powerful, effective and relatively easy to develop biofuel, albeit one that is limited by the amount of waste oil produced and appropriately recycled.
Adopting Biofuels And Electrofuels
Finally, the cars themselves are using a proprietary “sustainable fuel” designed to work with the complex hybrid engines brought into use for the 2026 season.
The fuel used is a ‘drop-in’ replacement, with the implication that the production system could be immediately adapted into road cars, if the systems could be scaled beyond the 22 races of the current F1 season.
What Was The First Biofuel-Powered Car In Motorsport?
These incredible achievements seen in the world of F1 can be traced back 22 years to an ambitious early attempt at sustainable racing, one that impressed at Le Mans to the point that it may have changed the course of motorsport history.
The Nasamax team used modified Reynard chassis and a Judd engine developed to run on fuel derived from potatoes and sugar beets, as first-generation biofuel was the only type available at scale at the time.
It also used a nitrogen-rich air mix, as the bio-ethanol used was more flammable than conventional racing fuel, and regulators allowed the team to use a much larger fuel tank than the regulations typically allow to account for the lower fuel efficiency found with bio-ethanol at the time.
The car, the first homologated under the then-new LMP1 class, ended up faring remarkably well. It qualified 14th overall out of 48 entrants and managed to finish an astounding 17th overall and 7th in its class out of nine finishers.
Whilst financial issues ultimately caused Nasamax to pull out of Le Mans, its influence can be felt today as all major motorsport disciplines are shifting to sustainable fuels.
