All-electric, hydrogen-powered Green GT H2 to compete in 24-hour Le Mans car race

At this year’s 24 Hours of Le Mans, history will meet the historic. Launched in 1923, Le Mans is the world’s oldest long-form auto race, steeped in tradition, and for the first time in its life it will host a competitor running without any gasoline whatsoever. The organizers only just allowed the introduction of hybrid vehicles in 2008, starting with Audi’s R18 E-Tron Quattro, and just four years later they’re struggling with the addition of entirely petroleum-free vehicles. Green GT, the maker of the new, all-electric racer called the H2, hopes its latest vehicle can put the skeptics in their place.

The name H2 is no accident. While the phrase “electric car” generally conjures images of trunks full of batteries, conventional auto batteries were considered both too weak and too heavy to be useful for a long-haul race like Le Mans. A loose interpretation of the rules was needed to allow the Green GT vehicle to compete at all, as Le Mans regulations were amended in 2008 to allow new cars using batteries for fuel. The H2 uses hydrogen cells, however, reducing roughly two tons of batteries to a fuel cell that can fit in a sleek, modern racer.
