Hot dry rock (HDR) is an extremely abundant source of geothermal energy that is difficult to access. A vast store of thermal energy is contained within hot – but essentially dry and impervious crystalline basement rocks found almost everywhere deep beneath Earth''s surface. [1] A method for the extraction of useful amounts of geothermal energy
The concept of Hot Dry Rock (HDR) geothermal energy originated at Los Alamos National Laboratory in the early 1970s, to exploit the heat contained in those vast regions of the earth''s crust that contain no fluids in place—by far more widespread than natural hydrothermal resources. re-sealed—rock mass.
However, using SCCO2instead of water in a closed- loop HDR system offers three significant advantages over the original Los Alamos concept: 1. The very significant wellbore density difference between the cold SCCO2in the injection well (about 0.96 g/cc) and the hot SCCO2in the production wells (about 0.39 g/cc) would provide a very large
