Air Liquide supplied the renewable hydrogen necessary to light up the Eiffel Tower for a laser show during the "Paris de l'hydrogène" event organized by Energy Observer.

The hydrogen is also used to power the exhibition village. Originally the first autonomous, zero-emission hydrogen vessel, Energy Observer now combines expeditions and climate-oriented technical innovations. The exhibition features hydrogen as a cornerstone of the energy transition and as a means to succeed in building a low-carbon society.

“Paris de l’Hydrogène” is an exhibition dedicated to renewable energy, running until 30 May 2021 at the Champ de Mars. It is organized by Energy Observer, with the support of the City of Paris. Air Liquide is participating in this event by supplying the 400 kg of renewable hydrogen needed to run the village for the duration of the event. This low carbon energy carrier was also used to light up the Eiffel Tower with renewable energy for a laser show that took place on May 25th.
