A multimodal hydrogen ecosystem at the heart of the Auxerrois territory

• 1 MW of electrolysis
• 1 hydrogen station: 400 kg of green hydrogen produced per day and 2,200 tons of CO2 avoided per year
• Supply of 5 buses in the urban area of Auxerre (in due course light and heavy vehicles)
• Auxerre, France | Contract: 2020, inauguration in autumn 2021

Today the largest green hydrogen production and distribution site in France.

Inaugurated in October 2021, the AuxHYGen station in Auxerre is today the largest green hydrogen production and distribution site in France.

McPhy supplies to Hynamics the hydrogen equipment for the AuxHYGen project: a 1 megawatt-capacity electrolyzer and distribution station. This dual technology will allow the station to produce and distribute up to 400 kg of green hydrogen per day to first supply a fleet of 5 buses, and thus avoid the release into the atmosphere of 2,200 tons of CO2 per day in a year.

This project begins the development of a real multimodal hydrogen ecosystem in the Auxerrois region. The municipality, supported by ADEME, aims to triple the production capacities of the AuxHYGen station by 2025. [download project press kit | FR]
To date, it supplies 5 buses in the urban area of Auxerre, but aims to supply hydrogen to other modes of transport: light vehicles, trucks and even trains.

By helping to improve air quality, this zero-emission mobility project is an important step in the energy transition and fight against climate change of the region.

ADEME (Agence de la Transition Écologique) is a partner of this project

This project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking program within the framework of the European Union’s “Horizon 2020” research and innovation program under grant agreement n ° 779563.
