Clermont Auvergne Métropole, in partnership with SMTC-AC and Keolis, has inaugurated the first hydrogen bus line in the Clermont-Ferrand region, marking a significant step toward environmentally friendly mobility. This innovative project combines retrofitted and new buses to reduce the carbon footprint of the public transport network.
Hydrogen bus line in Clermont-Ferrand: a step towards more sustainable mobility
A technological solution for an effective energy transition
Starting in December 2024, line 35-36, running between Clermont-Ferrand and Pont-du-Château via Lempdes, will welcome four buses retrofitted by GCK Mobility and a new bus by SOLARIS, all powered by hydrogen fuel cells. Retrofitting, where the internal combustion engine is replaced with a hydrogen-electric engine, extends the lifespan of the vehicles while limiting costs and environmental impact. In 2025, the fleet will grow with three additional retrofitted buses and six new hydrogen buses.
A local shared hydrogen station
The renewable hydrogen station in Cournon d’Auvergne, operated by Hympulsion, will play a key role in refuelling this fleet. This initiative also includes the opening of a new Keolis depot, designed to meet the needs of this energy transition. Altogether, these buses will reduce CO2 emissions by 594 tonnes per year (based on ADEME’s calculation method).
A model project for the future of mobility
This initiative is part of a comprehensive energy transition strategy led by Clermont Auvergne Métropole, involving local partners such as GCK Mobility (vehicle retrofitting), SYMBIO (fuel cells), and R3I (depot development). By combining technological innovation and local economic development, the project reflects the metropolitan area's commitment to promoting sustainable solutions for the future.
As a mobility operator, Keolis demonstrates its ability in this project to support its clients in adopting the most suitable solutions for their communities in terms of energy, vehicles, infrastructure, and passenger service quality.
