Today, the need to produce CO2-neutral energy from renewable resources is motivating major research organisations and governments to turn their efforts towards optimising geothermal energy extraction methods. In this context, understanding heat transport in fractured media is essential for developing and testing new technologies for energy production and storage in geothermal reservoirs.
In fractured reservoirs, flow and transport processes are characterised by high variability at the fracture and fracture network scales.
At the two scales just mentioned, the role of heterogeneity on heat transport is still poorly understood. It limits the development of geothermal energy and heat storage in crystalline basement environments like Brittany.
The THERM project aims to improve the understanding of the coupled processes involved in heat transport. This will be achieved through the study of new in situ experiments, combined with heat transport modelling on multi-scale fracture networks.
The results of the THERM project should lead to an improved ability to predict the efficiency and longevity of geothermal systems.
