As the leading academic project partner, the University of Leoben will contribute fundamental research and simulations. It will use laboratory experiments and proprietary simulation software to investigate the geochemistry and model the reactive transport processes concerned. Possibilities for de-mixing hydrogen and natural gas will be tested in long-term experiments on a set of three pressurised reactors filled with porous materials. The influence of the hydrogen-methane mixture on the properties of the materials used in pore storage facilities (cement and various grades of steel) will also be examined in laboratory experiments.
In addition, a risk assessment will be performed to identify and evaluate the potential risks of underground hydrogen storage. Finally, a life cycle assessment will determine the environmental impacts of viable hydrogen storage scenarios.
