Potential Application Of Vacuum Insulated Tubing For Deep Borehole Heat Exchangers

One of the ways to extract geothermal heat from the Earth’s crust is through Deep Borehole Heat Exchangers (DBHE). These can be either drilled especially for a heat extraction or, more cost-effectively, reconstructed from already-existing, negative, or abandoned oil or natural gas wells. In many depleted boreholes, exploiting underground geothermal waters is either impossible or
