Efficient Exhaust Technology for Hydrogen Engines

- Exhaust-emission conversion for trucks with hydrogen engines

- Expertise transfer for new technology

- Premiere at the Hannover Messe 2022


Esslingen (Germany), 24 May 2022 – Purem by Eberspaecher has decades of experience in the development and production of exhaust-emission conversion systems for use in conventional internal combustion engines and hybrid drives. The experts are now applying this expertise to hydrogen engines. At the Hannover Messe, the company will be presenting its H2-ICE exhaust system for the first time from May 30 to June 2 in Hall 13, Booth D71. 

Hydrogen engines have great potential as a drive type with CO2-neutral fuel, especially for heavy-load transport and in off-highway vehicles. With the H2-ICE exhaust system, the exhaust gas specialists from the Eberspaecher Group are presenting the system specially designed for exhaust-gas aftertreatment in hydrogen engines. The H2-ICE exhaust system ensures that the exhaust system will function properly, taking into account the specific requirements of this fuel. This is because even in hydrogen engines, exhaust gases such as nitrogen oxide and small amounts of particles and unburned hydrocarbons are produced from the engine oil pathway. In addition, the metered addition of the urea-water solution can cause particles to form. The applied technology is based on the well-established expertise of Purem by Eberspaecher in the development and production of exhaust-emission conversion systems for applications with fossil fuels, which are now being adapted to the CO2-neutral fuel. Among other things, SCR technologies with urea-water solution are used as reducing agents for optimum nitrogen oxide conversion. The system is modular and can therefore be specifically adapted to the needs of individual customers and applications.

The exhaust system for the Purem by Eberspaecher hydrogen engine is just one of the Eberspaecher Group’s group-wide hydrogen activities. By adding fuel cell solutions to its product portfolio, Eberspaecher is pursuing the goal of shaping the clean and quiet mobility of the future. At its trade fair booth, Eberspaecher will also be presenting new components for use in stationary or industrial applications. These include air compressors from Eberspaecher Vairex, as well as exhaust technology systems in fuel cell applications.
