Hydrogen is proposed as key fuel for the decarbonisation of energy systems, where it could be a low-carbon alternative to natural gas. Suitable large-scale storage could be required to help overcome the intermittency and seasonal variations in supply. The geological storage of hydrogen involves the injection into the subsurface, either into engineered salt caverns or porous geological formations. Existing studies have explored some mineral-hydrogen interactions, but how these vary with different mineralogical compositions and the effects of microbial respiration is not well described. This project will investigate the potential reactivity of hydrogen with naturally occurring mineral and biological components in the subsurface. It will consider the impact of residence time and cyclic loading and unloading on reactions during the storage of hydrogen.
This project will take an integrated approach by utilising petrophysical and geochemical characterisation of rock types to inform the design of microbial community experiments.
- Characterise the mineralogical and biological components present. This will include determining the mineralogical composition and heterogeneity of geological materials and draw together findings of previous subsurface biosphere studies to characterise the presence and abundance of different microbial species. This will help parametrise the analytical experiments.
- Effect of mineralogy and microbial communities on hydrogen reactivity. Non-uniform distribution of water and hydrogen will affect effective kinetics of hydrogen consumption and it is likely that sites of activity will be at the interface between rock and the water. Lab based experiments will use 16S rRNA sequencing to identify if different rock types influence the growth of groups and their associated functions.
- Implications for hydrogen storage site selection. The results of both the geological characterisation and the reactivity experiments will be considered in the context of the impact on long term storage.
The findings from the PhD will provide an improved understanding of some geochemical aspects of the geological storage of hydrogen in the subsurface. ay 2021.
