Current Projects

Thermodynamics of Hydrogen Refuelling

The main goal is the analysis and understanding of the flow, heat and mass transfer phenomena during the high pressure refueling process. The approach is based on three levels, the basic thermodynamic analysis of the Instationary process, the detailed simulation based on solving the Reynolds Averaged Navier Stokes (RANS) equations and the more detailed solution of the flow and heat transfer based on Large Eddy Simulatios (LES) of the turbulence coupled with the RANS approach in order to achieve the desired accuracy. Targeted experiments are been performed in order to validate the simulations. Further information can be found here

Production of synthetic methane (Project MEGA)

The project focuses on the production of synthetic methane from green hydrogen and atmospheric CO2. The reactants can be produced locally from renewable electricity. As part of the project, a demonstration plant will be set up at move to demonstrate a methanation process developed at Empa. In addition, waste heat from the existing components will be integrated into the process. The synthetic methane will be offered for filling at the CNG filling station.

Flow Metering and Purity Measurement when Refuelling Hydrogen (Project MetroHyVe)

Development of metrology to support the safe use of hydrogen in refuelling stations for the transport sector. The project will tackle the four measurement challenges that currently prevent the industry from meeting requirements set by International Standards such as flow metering, quality control, quality assurance and sampling.
