Hydrogen is a low-emission energy source and can be used in fuel cells as well as in combustion engines. Besides the ecological aspects, long range, short refueling times and cost efficiency are the main advantages.

Poppe + Potthoff supplies hydrogen lines with certified interfaces, subsystems for H2 and dual fuel injection as well as numerous components for hydrogen drives at system pressures of up to 700 bar.

In addition, we develop and build special machines designed for pressure cycle testing, burst and function testing as well as checking the hydrostatic strength of media carrying components for H2-applications e.g. valves, pipes, pressure cylinders, storages and other parts. Hydrogen Propulsion


The electric drive is warming up for the mobility of the future. The fields of application and markets are growing rapidly, and so are the demands – especially in thermal management.

In electric vehicles, it is crucial to keep the electric motor, the power electronics and the battery within an optimal temperature range. Heating and cooling the vehicle interior also influences the range. Media-carrying components must withstand the highest stresses at temperatures as low as -40 °C.

Likewise at temperatures of up to +140 °C. Poppe + Potthoff Maschinenbau develops test stands for e-mobility. These allow for testing components and systems for leak tightness, energy efficiency and fatigue strength at varying pressures and temperatures.
