RETROFIT

Conversion of diesel coaches to hydrogen

SAFRA has developed a product to support the decarbonization of transport vehicles with the H2-PACK®, a kit that allows diesel coaches to be retrofitted with hydrogen. Supported by the French Environment and Energy Management Agency (ADEME), this kit is a real technical feat that allows the transformation of a diesel bus engine into a Zero Emission vehicle running on hydrogen and emitting only water vapor.

Our retrofit kits proposed in pre-marketing are the result of the first experimentation work currently carried out on intercity coaches of the Mercedes Intouro brand in the Occitania region.

Approval of transformations according to the technical and administrative provisions of the order of March 13, 2020

The main principles of coach retrofit :

  • Removal of the engine, tanks…
  • Installation of a new energy chain, in compliance with regulatory constraints
  • Connection to the existing traction chain
  • Integration of new computers and software
  • Interfacing with existing equipment
  • Approval of the transformations according to the technical and administrative provisions of the order of March 13, 2020

Why is it interesting?

There are several interests in retrofitting a coach. Economic, of course, since the cost of the retrofit is of course lower than the purchase of a new vehicle, but also ecological, since the retrofit extends the life of the vehicle. Its replacement is thus postponed by several years, and the same vehicle will finally be able to circulate in Low Emission Zones (LEZ) on which it could not circulate before. Some on-board components and systems such as ticketing equipment do not have to be reinstalled.

Our H2-PACK® kit is supported by ADEME as part of the France 2030 investment plan.
