Since 2018, with the launch of the MissionH24 program, a collaboration between the ACO and H24Project, the deployment of hydrogen in racing has been one of the priorities of the 24 Hours of Le Mans in its quest for a zero CO2 emissions race.
Many milestones have already been reached: testing of prototypes using gaseous hydrogen, construction of a gaseous hydrogen station, drafting of standards, establishment of safety rules...
For the future hydrogen prototype category, hydrogen stored in liquid form (which is denser) has been selected by the FIA. It will be able to power prototypes using fuel cells or combustion engines.
On Thursday, June 11, 2026, the first liquid hydrogen prototype took the track at Le Mans. The Toyota TR LH2 Racing Prototype, driven by Kazuki Nakajima. Spectators as well as numerous observers followed this special lap.
The Alpine Alpenglow, driven by David Praschl, also on the track this Thursday, will attempt to set a track record on Saturday at over 313 km/h.
Hydrogen is thus proving its potential and reliability, and demonstrating that zero CO2 emissions racing is possible.
