If successful project will allow water to be injected down borehole to be superheated by rocks beneath
A drilling rig is about to arrive at the Eden Project in Cornwall to bore almost three miles down into the granite crust in search of “hot rocks” that will be used to warm the attraction’s biomes and other buildings.
The first of the lorries carrying a 450-tonne, 55-metre-high drilling rig will arrive on the outer edge of the site next week, and if all goes well the geothermal scheme will begin operating by Christmas or early next year.
