The origin of the H2 dates back to 2009 after the construction of a first prototype of electric competition called GreenGT 300 kW and powered by lithium/ion batteries.

The autonomy of the latter having quickly proved to be a defect of the 300 kW, GreenGT decided to use a fuel cell to provide additional energy necessary for electric motors.

On 22 September 2011, the life-size model of the H2 passed through the wind tunnel for the first time, in France, at the IAT (Aerotechnical Institute) of Saint-Cyr-l'École.

During the race weekend, on 16 June, it became the first car powered by an electric-hydrogen powertrain to complete a lap of Circuit de la Sarthe.
