The Hydrogen 2024 future of Le Mans 
A Hydrogen-powered class is planning to be introduced into the 24 Hours of Le Mans for 2024. To achieve this, the ACO and GreenGT have set up an initiative called MissionH24 which has developed the first prototype, the LMP2HG. This revolutionary racer will be taking to the track for the 3rd time, racing on the Bugatti circuit on the 28th of March, as part of the Les Assises de I?Automobile conference.
So, how does hydrogen work in a Racecar" Here are the top 5 facts you need to know…
1. Safety
You would not be alone in thinking that hydrogen is a dangerous gas to be packaging into a racecar. However, modern safety measures and standards have now contained any risks associated with hydrogen. So much so, that fire prevention professionals now consider hydrogen safer than any other fuel used in open air. For example, the refuelling pitstop at the first demonstration at Spa last year was completed by an operator wearing normal clothes. There was no need for overalls or a helmet – just the simple connection of the valve. 2. Hydrogen fuel cell
A hydrogen fuel cell is an electromechanical cell that converts the chemical energy from a fuel into electricity through the electromechanical reaction of hydrogen fuel with oxygen. This differs from batteries because a fuel cell continuously sustains the chemical reaction using fuel and oxygen from air, whereas the chemical energy in a battery comes from the chemicals already prese...
