A new government project to encourage renewable energy has funded the UK’s first deep geothermal heat network that will gather energy by digging 5,275 metres to harness energy from granite rocks.

Located near Truro in Cornwall, Langarth Deep Geothermal Heat Network is a £22million project and one of seven sharing a £91 million grant under the Green Heat Network Fund (GHNF).
