GreenGT LMPH2 Hydrogen-Electric Racer Set for 2012 Le Mans Entry
Swiss firm GreenGT has revealed the LMPH2, a hydrogen-electric prototype aiming to compete in an experimental class at the 2012 24 Hours of Le Mans.
GreenGT, the Swiss engineering firm, has unveiled the LMPH2, a hydrogen-electric prototype designed to compete in the experimental class at the 2012 24 Hours of Le Mans. The car, which combines electric drive with hydrogen fuel cell technology, is part of a push by organisers to showcase zero-emission vehicles on one of motorsport’s most demanding stages.
The LMPH2’s powertrain features electric motors drawing energy from a hydrogen fuel cell, with the option of 700 bar high-pressure tanks holding about 12kg of hydrogen. According to GreenGT, the system delivers a peak output of 300kW, or roughly 402bhp, making it competitive with conventional internal combustion and hybrid rivals in terms of raw power.
The Automobile Club de l’Ouest (ACO), which organises Le Mans, confirmed the LMPH2’s planned participation in an experimental class for 2012. This initiative comes as the ACO seeks to encourage alternative propulsion technologies at the world’s most prestigious endurance race. The LMPH2 will not compete for overall victory but will run as a demonstration of zero-emission racing capability.
Hydrogen-Electric Powertrain Details
GreenGT’s system employs high-pressure hydrogen storage feeding a fuel cell stack, which generates electricity to drive the car’s motors. The 12kg hydrogen capacity is stored at 700 bar, a pressure similar to that used in current hydrogen road cars. The company claims this configuration provides both high performance and the ability to run stints comparable to combustion-powered cars, although exact range and refuelling times have not been published.
The LMPH2’s entry comes as Le Mans opens the door to new propulsion technologies. For 2012, Toyota also confirmed a hybrid LMP1 entry, while Peugeot withdrew its diesel programme citing economic pressure. The ACO’s experimental class gives manufacturers and engineering firms a platform to develop and showcase alternative drivetrains without the constraints of conventional technical regulations.

What the LMPH2 Means for Endurance Racing
While the GreenGT LMPH2 is unlikely to challenge for outright honours, its presence at Le Mans signals growing interest in hydrogen and electric propulsion at the highest level of motorsport. The ACO’s willingness to accept such entries reflects a broader shift towards sustainability and new technology within endurance racing. For GreenGT, Le Mans offers both a technical trial and a global showcase for its hydrogen-electric system, with the potential to influence future regulations and manufacturer involvement.
The LMPH2’s performance against established petrol, diesel and hybrid competitors will be closely watched, both by race organisers and by manufacturers considering their own alternative propulsion projects. The car’s development and race participation could help set benchmarks for hydrogen-electric technology in motorsport, as well as inform future advances in road-going vehicles.
