The current practice of producing electricity by transporting underground fossil fuels (coal mining, oil and natural gas drilling) above ground; followed by above ground combustion and subsequent underground CO2 sequestration; has historically presented cost and environmental problems for handling, processing and disposing large quantities of undesirable CO2 emissions and ash. The proposed transformational and marketplace disruptive technology, leaves CO2 and ash generated from in-situ combustion of fossil fuels underground for subsequent local separation and sequestration, transports thermal energy from the underground combustion to above ground, for power generation.
It is expected that the proposed concept will be more cost effective and energy efficient than the conventional process while eliminating CO2 emissions. If successfully implemented, this concept may have impact similar to horizontal mining and hydraulic fracturing on enhancing U.S. energy security. This paper will discuss some of the preliminary calculations.
