Geothermal energy from fractured granites is a promising and sustainable source of heat derived from the Earth’s internal heat stored in rocks. This type of geothermal energy exploits deep, fractured granite formations, which are rich in heat and can serve as effective reservoirs for extracting thermal energy. In regions where granite formations are fractured, water can be injected into these fractures to create an enhanced geothermal system (EGS). The water circulates through the fractures, absorbing heat from the surrounding rocks, and is then pumped to the surface where it can be used for electricity generation or direct heating. The high temperature and thermal conductivity of granite make it an ideal medium for geothermal systems, and advancements in drilling and reservoir stimulation technologies have made it increasingly viable for large-scale energy production. This form of geothermal energy is seen as a key solution for providing reliable, low-emission power in areas with suitable geological conditions.

We believe that deep geothermal energy should form a share of the renewable energy mix in UK alongside wind, solar and others. Ultimately it is the most reliable and not dependant on weather conditions!
