Diary Innovation project Hydrogen test bench



Sonplas has over 25 years of experience in the assembly and testing of diesel and gasoline injection components. We want to use our experience for a greener future, with all the new fuels, including hydrogen.

With our test bench for testing hydrogen-carrying components with real fuel, we aim to help our customers develop the components to advance this climate-friendly energy source.

An exciting as well as challenging project, accompany us on this way.
