Less Greenhouse Gases through Hydrogen Engines

DFG funding for engineering sciences

Hydrogen can be used CO2-free not only in fuel cells, but also in engines to power vehicles. How such hydrogen engines can run smoothly and efficiently is being researched by several universities led by the UDE in a project that, in its second funding period, is looking at the use of hydrogen in gasoline engines. The German Research Foundation (DFG) is funding it with about 2.8 million euros, 852,000 of which will go to the UDE.

Since 2019, the four universities of Aachen, Darmstadt, Duisburg-Essen and Stuttgart have been investigating how the combustion process in car engines can be optimized. While the first funding period focused on conventional gasoline fuels, the scientists are now researching hydrogen as an alternative fuel. The project is divided among the universities into seven subprojects. Two of them are at the UDE, which also provides the project spokesperson, Prof. Dr. Sebastian Kaiser.

His group is currently investigating the mixing of fuel and air in experiments using optical measurement techniques in the engine cylinder. Together with ignition, this process is one of the main influences on cyclic fluctuations.

In the second subproject, a team led by CENIDE member UDE professor Andreas Kempf is using simulations to analyze how cyclic fluctuations and the stability of the engine process change when the components of the fuel are varied. “The goal of our projects is to be able to predict the irregular combustion processes and fluctuations. Then we could develop appropriate countermeasures to optimize hydrogen engines in efficiency and reliability,” Professor Kaiser said.
