Engineering the subsurface is critical to reaching net zero: underpinning new clean energy (geothermal, offshore wind); enabling large-scale energy storage (pumped storage hydropower; thermal storage, compressed air, hydrogen); and providing safe long-term storage of waste (geological disposal of CO2, radioactive waste disposal). My research spans fundamental geoscience research on subsurface processes, understanding geological and interpretational uncertainties, through to the social science of communicating these geological concepts & uncertainties, and demonstrating novel technologies through in-ground experiments. To help achieve the large-scale changes in our energy system and society that are needed to meet - and ideally exceed - our net zero targets, I work in close collaboration between academia, industry, government and civil society across a wide range of disciplines.
