How Le Mans is using grape residues and hydrogen to drive a sustainable future ⬇️ LeMans24
Le Mans is buried deep in the heart of France’s famous wine country – and believe it or not, thanks to fuel manufacturer TotalEnergies, the local vineyards are now playing a vital role in developing of a range of sustainable energy solutions for the world’s most famous 24-Hour race.Motorsport – and Le Mans in particular – has long been a pioneering proving ground for new technologies.
Electric power, however, is not ideal for all forms of racing, due to the heavy weight of batteries. In endurance, the high speeds and long stints push the weight of batteries to the limit and to match the current performance of the top classes in a sustainable way requires a different approach.Last year, for the first time, the entire Le Mans grid was supplied with 100% certified* sustainable fuel and this will continue in 2023.
Hydrocarbon fuels are extremely powerful – providing 50 times more power than a battery for the same weight. In contrast, biofuels or synthetic fuels made from CO2 from the air and water, like those being pioneered by former F1 technical director Paddy Lowe, pack the same punch as petrol, but do so in a more sustainable way.
#93 Peugeot Totalenergies Peugeot 9X8 of Paul Di Resta, Mikkel Jensen, Jean-Eric Vergne, Stoffel VandormeThanks to a ground-breaking refilling station developed by TotalEnergies, this is coming closer to reality and Aubry explains: “When the car first did a demo lap at Spa in 2019, I remember discussing with our motorsport Vice President about doing more with it, more than just a few laps.
Hydrogen use, however, has so far been limited by filling station size and fuelling speeds. A standard refuelling station in Europe covers a huge footprint and can only fill at a rate of 1kg per minute. Considering the H24 has 8kg in the tank – far smaller than a fully-blown Le Mans hypercar – that is extremely limiting.
