08-30-2017: Supercritical Fluid Energy Manufacture
How can Z Group Energy (ZGE) manufacture supercritical fluid below ground? Good question. ZGE can do this by cost effectively employing its patented, sealed geothermal system to depths enabling the conductive capture of hot rock heat at temperatures high enough to produce supercritical fluids, say water above 374°C. Using H2O as the thermal energy carrier […]
08-17-2017: Are Supercritical Fluids Critical For Cost-Effective Geothermal Electricity Production?
Why might supercritical fluids be critical for cost-effective geothermal energy? Before answering, what is a supercritical fluid? Per Wikipedia[1]: A supercritical fluid (SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist. It can effuse through solids like a gas, and dissolve materials […]
