Research Projects

Green hydrogen from brewing biomass

In this project, the Bonn-Rhein-Sieg University of Applied Sciences will analyse the availability of brewer's grains and the sustainability of procurement and processing. The design of a suitable electrochemical electrolysis cell will be carried out at Robert Gordon University.

Project management at the H-BRS

Prof. Dr Tanja Clees Prof. Dr Stefanie Meilinger

TransHyDE-Sys is a system analysis project and a joint project within the lead project TransHyDE. In addition to the system analysis, there are also implementation and research projects on the topic of H2 transport in the lead project. As a cross-sectional project, the system analysis performs a special function: On the one hand, essential system knowledge for the time-dependent construction and coupling of the energy infrastructures is generated with the help of own modelling and simulation work as well as ecological analyses.

TRE3L - TREE-Energy Lab

The institute TREE operates the TREE-Energy Lab (TRE3L) in the university's Center of Applied Research (ZAF)  with it's industrial partners GKN Driveline and GKN Sinter Metals. In the three sub-labs Powder Fabrication-Lab, Mobility-Lab and Hydrogen-Lab the three partners work on innovative techniques in powder metallurgy and recent topics of environment friendly mobility and energy-efficiency. These labs are supported by a Simulation-Lab.
