Raymond Mushabe

PhD Candidate, Experimental reservoir physics for underground hydrogen storage in porous media

The doctoral research Raymond is doing is part of the research work done at the Centre for Sustainable Subsurface Resources (CSSR-WP2) in collaboration with University of Bergen. The team on work package two (WP2) focusses on short-cycle (hours/days/months) energy storage in porous media, where subsurface hydrogen storage is the key topic. Raymond will experimentally quantify hydrogen flow and distribution in porous media at the core by combining traditional core flooding test with modern in-situ visualisation methods (MRI and PET). Hydrogen saturation functions will be measured at a range of conditions (varying pressure, temperature, injection and withdrawal rates). Focus on microbial activity on hydrogen storage will follow the two steps above at a core scale. At this stage imaging methods MRI and PET will be vital. Correlation and upscaling between core and pore scale observations will then follow. And finally data from experimental results will be provided to the simulation team as a validation datset or quality simulator input data .
