Hydrogen as a bridge between CHP and climate-friendly energy

 

WJ POWER and Karlsruhe University of Applied Sciences start LeanStoicH2 research project funded by the Federal Ministry of Economics and Energy together with other project partners IAVF Antriebstechnik GmbH, Weißgerber Engineering GmbH and MOT Forschungs- und Entwicklungsgesellschaft für Motorentechnik, Optik und Thermodynamik GmbH.

 

Within the framework of the climate targets and the associated expansion of combined heat and power generation (CHP), hydrogen is considered to have the potential to be able to chemically store and transport large quantities of surplus electricity from renewable energy sources ("power-to-gas"). The current research project "LeanStoicH2" of the Karlsruhe University of Applied Sciences under the supervision of Prof. Dr.-Ing. Maurice Kettner aims to make use of this property as a bridge between CHP and climate-friendly energy sources and to develop a combustion process for stationary natural gas engines which, by adding hydrogen, achieves an improvement in efficiency and a reduction in emissions compared to conventional processes.

The main focus here is on the influence on the combustion behaviour and efficiency, raw emissions (NOx, HC, CO) and the wear behaviour of various components and modules. In order to be able to investigate these parameters, our HMG 434 4-cylinder naturally aspirated engine is built in two variants and compared with a reference (conventional lean-burn process). The focus is on the design with a donor cylinder concept, in which a single cylinder is operated with hydrogen and its exhaust gas (free of water and CO2) is being recycled to 100%.

The engines used for this purpose are provided by WJ POWER. Our development team has been involved in the project from the very beginning and is in constant exchange with the scientists during the further course of the project to discuss intermediate results and contribute practical experience.

Find out more about the setup and other details on the LeanStoicH2 web site.

We look forward to incorporating the knowledge gained into our engine production in the future - for the optimal, economical and ecological operation of your CHP!

We will be happy to answer any further questions you may have at any time.
