A new solution promises to revolutionize sustainable transportation by optimizing the refrigeration and fuel systems in hydrogen-powered trucks and buses
Continental, a global automotive solutions giant, has announced a major breakthrough for the sustainable transportation sector. The company has developed a new solution for refrigeration and fuel systems in trucks and bus powered by hydrogen.
The innovation promises to reduce material wear, increase autonomy and extend the useful life of vehicles, bringing important advances to sustainable mobility.
Innovation in the cooling system with synthetic rubber
A Shelf developed a cooling system for the powertrain of hydrogen-powered commercial vehicles, designed to minimize ion leaching into the fluid circuit.

This innovation uses lines made with synthetic rubber based on EPDM (ethylene propylene diene), a material distinguished by its high resistance to the penetration of unwanted ions.
This technology solves a critical problem: ion leaching can cause degradation of essential components such as the proton exchange membrane (PEM), responsible for the operation of the fuel cell.
With the new solution, wear is reduced, and the useful life of components increases, resulting in lower maintenance costs.
Thermoplastic barrier
One of the major challenges in using hydrogen as an energy source is its low density and high volatility, which increases the risk of leaks.
To address this problem, Continental has developed a hydrogen line with a special thermoplastic barrier that prevents hydrogen molecules from escaping, even with their tiny size.
This makes the system safer, avoiding flammable mixtures of hydrogen and air, which could cause accidents.
In addition to safety, the new technology reduces fuel loss through permeation, increasing the autonomy of fuel cell vehicles.
Original Equipment Solutions (OESL)
The innovation is the result of the expertise of Continental’s new business area, Original Equipment Solutions (OESL), a unit of the ContiTech Group.
This area was created to provide specialized technical support to original equipment manufacturers (OEMs) and develop advanced solutions for the transition towards sustainable mobility.
OESL brings together decades of Continental expertise in fluid circuits and combustion engines to apply them to hydrogen-based propulsion systems.
The combination of expertise in materials and high-precision engineering allows us to create solutions that combine tightness, flexibility and resistance to high pressures — critical factors for the safe and efficient performance of hydrogen-powered vehicles.
