Hydrogen Combustion Technology Added To Options For Future Le Mans Regs

A brief announcement from the ACO President Pierre Fillon and FIA Endurance Commission President Richard Mille has confirmed that the future regulations for hydrogen-fuelled cars at the 24 Hours of Le Mans will now encompass Hydrogen combustion technology as well as retaining the option for Hydrogen Fuel Cell tech.

The ACO have been at the forefront of a drive to introduce Hydrogen as a fuel source in the sport since 2018 and, since then, there have been progressive steps in development together with their technology partners on demonstration projects, whilst continuing dialogue with interested manufacturers.

No details are yet given on interest from manufacturers but recent media reports in France seem to confirm that the re-existing interest from Hyundai in fielding a fuel-cell powered car in the coming years is still alive whilst sources close to Toyota have suggested to DSC that their current technology demonstrator racer utilising Hydrogen combustion marks the early stages of developing that route towards more capable race (and road going) machinery.

At present the line from the ACO is that they are, “in close collaboration with the FIA, working towards the creation of a class for Hydrogen-powered prototypes at the 24 Hours of Le Mans in the next few years.”

Their is continued development too on MissionH24, a joint venture between the ACO and GreenGT, conducting research and development in areas such as safety, performance and refuelling.

Pierre FillonPresident of the Automobile Club de l’OuestSince 2018, the hydrogen ecosystem has evolved enormously. We are learning by doing. We are exploring possibilities. And that is exactly the objective we set ourselves five years ago when we launched MissionH24. The fuel cell was initially chosen for its potential, which is still relevant. Today, the hydrogen internal combustion engine is also presented as a possibility for manufacturers. The 24 Hours of Le Mans regulations have always advocated freedom and variety. As such, we are officially announcing that both technologies, fuel cell and hydrogen internal combustion engine, will be accepted and authorised for manufacturers wishing to enter the 24 Hours of Le Mans in the Hydrogen category. I would like to highlight the tremendous work carried out by MissionH24, alongside the ACO and FIA. We are all aware of the challenges facing the future of motorsport, and of the need to decarbonise mobility, and we are addressing them together.

Richard MilleFIA Endurance Commission PresidentHydrogen as a power source is yet to be fully explored in motor sport. However, given the fact that it offers a variety of options in terms of storage types and powertrains, it makes for a very interesting prospect. Implementing sustainable power sources across motorsport competition is one of the key targets of the FIA and part of our long-term roadmap. The key is to address the best solutions for different motorsport disciplines. Given the nature of endurance racing, hydrogen is one of the most suitable options, therefore the FIA fully supports the ACO’s MissionH24 project. We are working with them, sharing our know-how and expertise, to introduce a new power source to endurance racing.
