The latest hydrogen-powered GreenGT prototype has been demonstrated at this weekend's Spa European Le Mans Series round as part of an initiative to encourage fuel-cell technology.
GreenGT's experimental LMP2HG led the formation lap at the Spa 4 Hours. It also took to the track on Saturday to mark the launch of the Mission H24 drive by the Franco-Swiss group and Le Mans 24 Hours organiser the Automobile Club de l'Ouest.
Mission H24 is part of the push by the ACO to have zero-emission cars powered by hydrogen-fuel cells on the grid in a special class at Le Mans in 2024.
ACO president Pierre Fillon said: "We believe in hydrogen, just like we believed in hybrid technology and the introduction of a limited energy allocation [in LMP1].
"At the ACO, we have always worked alongside manufacturers and other stakeholders in the automotive sector, and we see Mission H24 as a genuine commitment to future mobility.
"With assistance from Green GT, we will rise to this new challenge."
The latest GreenGT LMP car was driven by four-time Le Mans winner Yannick Dalmas, who is also an advisor to the ACO.
"For a machine that is yet to enter the development stage, the whole package is really promising," he said.
The GreenGT undertook multiple laps of the Spa track and also underwent a fuel stop to show that hydrogen is a safe and simple fuel.
Present for the launch of Mission H24 was Henrik Hololei, director-general for mobility and transport of the European Commission.
The GreenGT LMP2HG is driven by four electric motors, two on each rear wheel, which are powered by electricity produced by the hydrogen fuel cell.
The car has a maximum power output of 480kW or 650bhp, which can be boosted by a 250kW or 335bhp by it energy-retrieval systems.
The LMP2HG is based on an ADESS LMP3 chassis.
GreenGT was originally due to take the Garage 56 slot on the Le Mans grid in 2013 before the project was delayed.
The original car, based on an chassis built by Welter Racing, was demonstrated during a break in qualifying at Le Mans in 2016.
