A major innovation in the CSG Group is the development of the hydrogen Tatra

A major innovation in the CSG Group is the development of the hydrogen Tatra. The development is being carried out in a five-member consortium of companies and academic institutions and is supported by the Czech Technology Agency. The result of the work will be a Tatra Force model series car powered by an electric drive with hydrogen fuel cells (FCEV).

The project was launched in 2021. The five-member consortium is led by ÚJV Řež. Tatra Trucks, DEVINN, the University of Chemical Technology in Prague and the Research Centre Řež of the UJV Group are also involved in the project. The project is supported by the Technology Agency of the Czech Republic.

Work on an innovative solution for a zero-emission hydrogen-powered truck prototype is expected to be completed in 2023. The prototype electric vehicle with a hydrogen fuel cell will be built on a robust Tatra Force chassis of the latest 3rd generation and equipped with a range of support technologies that will enable the vehicle to operate in challenging conditions.

For Tatra, as a manufacturer of cars for demanding conditions, it is important that an electrically powered car carries a source of electricity directly on board, i.e. that the car is independent of external sources. From this point of view, hydrogen fuel cell technology is the most promising for the future.

It is electric propulsion, with the fuel cell producing the necessary electricity by a chemical reaction from hydrogen on board the car. In addition to the traction electric motor, traction batteries and fuel cells, in this case two, there are also hydrogen gas tanks on the vehicle. There are six composite tanks with a capacity of 5 kg of hydrogen. The range of the car is 400 km per fill.


Compared to the more widespread battery electromobility today, hydrogen propulsion has an undeniable advantage in range. There is also no need for long vehicle charging times - hydrogen refuelling times are comparable to conventional petroleum-based fuel stations.

The chassis of the Tatra Force 3rd generation is available with one axle at the front and three axles at the rear. This configuration, with steered first and last axles, was chosen for better weight distribution and manoeuvrability. The prototype vehicle will be primarily intended for use in the mining industry, where it can be tested in the most demanding conditions.
