PhD Project: Geological controls on upper crustal heat flow for deep geothermal energy in Cornwall

Geothermal energy is a sustainable and stable energy resource that has a low carbon output. The presence of high heat producing granites in Cornwall makes it a prime target for geothermal energy in the UK. The United Downs Deep Geothermal Project (UDDGP) aims to target this resource by drilling two wells to depths of 2.5 km and 4.5 km, with expected temperatures in the region of 190oC. The heat extracted from these depths will be used to supply a demonstration power plant to generate electricity.

My research investigates uncertainties regarding the heat production and conduction models in SW England. This includes the high heat production from the granites and other contributions from mid/lower crustal and mantle sources. This will provide improved constraints on the subsurface temperature and increase the understanding of the potential geothermal resources in Cornwall.

I am based at the Camborne School of Mines, University of Exeter and funded through the NERC industrial case studentship, with GeoScience Ltd as case partners.
