Another potential location for accessing Geothermal Energy is Subduction Zones associated with Volcanic Arc Geology. Hydrothermal and/or petrothermal reservoirs are possible to be exploited for significant enthalpy with production and injection wells.
- Volatile fluid release from subducted crust includes carbon components from organic matter, carbonates, water and hydrous materials. These fluids rise up and some end up in deep hydrothermal reservoirs;
- Magmatism is melted slab rock containing many elements which similarly rise up bringing significant heat closer to the surface including into petrothermal reservoirs (fractured hot dry rock);
- Surface heat flux is a function of Moho temperature, magma temperature, crustal thickness, and magma ponding levels with heat conduction through the crust and heat advection by rising melts;
- These hydrothermal and petrothermal reservoirs are able to be exploited with production and injection wells to capture the heat for Geothermal energy from surface Binary ORC power generation equipment.
