Ground source energy in crystalline bedrock - increased energy extraction by using hydraulic fracturing in boreholes
The use of improved equipment and methodology can result in considerable reductions in the drilling costs for medium- to large sized ground source heat pump system in crystalline bedrock. The main point has been to use special techniques within hydraulic fracturing to create a larger heat exchange a...
