Tenneco Powertrain adds hydrogen to its engine testing capabilities
04 February 2023
Tenneco has established new test facilities for hydrogen-powered internal combustion engines at its Powertrain test centers in Burscheid, Germany, and Ann Arbor, Michigan. These two test cells specifically dedicated to hydrogen ICEs enhance the company’s globally integrated ICE test capabilities, supporting original equipment (OE) engine and vehicle manufacturers as they decarbonize the ICE.
Preparation of an H2 ICE test cell.
By adding H2-engine testing, Tenneco is well-positioned to provide technology solutions that can help to accelerate the reduction of carbon emissions of future combustion engine generations to achieve global climate goals faster.
We support a pragmatic approach of complementary technologies that provide solutions for different transportation sectors. We contend it’s not combustion-engine technology causing green-house gas emissions in the product-use phase; it is the fuel used in the ICE that defines the vehicle emissions.
Therefore, green hydrogen, which is produced from renewable energies and carbon-free by nature, offers great potential for cleaner transportation, especially in sectors difficult to electrify, such as heavy-duty commercial vehicles, on- and off-highway applications, and the industrial and marine sectors.—Stefan Rittmann, Vice President, Engineering with Tenneco’s Powertrain business group
As a leading supplier of engine components—including pistons, piston rings, bearings, seals and gaskets, valves, valve seats and guides, and ignition devices—Tenneco leverages its comprehensive ICE expertise in various hydrogen and alternative-fuel project partnerships with engine and vehicle manufacturers. Tenneco’s new test cells support manufacturers in their H2 ICE concepts, testing prototype engines and components for durability, wear, emissions, fuel-efficiency and performance.
Using our knowledge about the influence of hydrogen on the combustion process and on the Powertrain Control Unit (PCU), we are able to address hydrogen-specific challenges like pre-ignition and H2-slip into the crankcase as well as the influence on tribology and materials.
The R&D from our H2 test benches, along with support from our simulation tools like PRiME3D, can accelerate the development process and help our customers go to market with highly efficient H2 combustion engines faster.—Dr. Steffen Hoppe, Powertrain’s Director Technology Rings & Liners, Tenneco
Tenneco’s new H2 ICE test facilities provide a broad bandwidth of high-accuracy engine measurement capabilities, including:
- Light and heavy-duty engine testing up to 700kW
- Eddy current and AC dyno
- ECU connectivity, calibration and tuning: dynamic engine operation; driving cycles / engine in the loop
- H2 supply up to 50bar and 90kg/h
- H2 concentration measurement (exhaust and blow-by path)
- Combustion Analysis
- Emissions testing for HC, CO, CO2, NOx, FSN
- Gaseous emissions
- Particulate number (PN) count
- PN size distribution
- Particulate Matter (PM)
- Radioactive tracer for oil emissions
- In-line oil consumption and oil emission analysis
- Automated fuel map testing
- Ignition parameter evaluation
- Thermal shock testing
- Precise overall real-time engine monitoring
We don't need costly hydrogen fuelcells with costly platinum and costly batteries back-up . We should start commercialisation of hydrogen ice transportation, it is as efficient as fuelcells for one third of the cost.

The argument against H2 is how it is produced, i.e., by a gross polluting steam reforming process using fossil fuel feedstock that is mined also using gross polluting techniques. Currently over 90% of hydrogen is produced this way.
