System and method for energy and resource extraction with reduced emissions

A method for extracting heat from a reservoir, the method comprising:

• placing one or more co-axial tools underground, the co-axial tool having an outer pipe and an inner pipe located within the outer pipe, each of the outer pipe and the inner pipe being connected to a shoe so that a fluid flows through an annulus of the inner and outer pipes, reaches the shoe, and also flows through a bore of the inner pipe, wherein only the shoe is in contact with a coal seam located underground;
• fluidly connecting a power generator to a chemical processing unit to receive a fluid, and also fluidly connecting a first port of the power generator to the inner pipe and connecting a second port of the power generator to the outer pipe of the co-axial tool;
• and
• generating energy with the power generator based exclusively on a temperature difference of the fluid at the power generator and at the co-axial tool.

A heat extraction system for extracting heat from a reservoir, the system comprising:

• a co-axial tool configured to be placed underground, the co-axial tool having an outer pipe and an inner pipe located within the outer pipe and configured so that a fluid flows through an annulus of the inner and outer pipes, reaches a closed end of the outer pipe, and also flows through a bore of the inner pipe;
• and
• a power generator fluidly connected to a chemical processing unit to receive the fluid, and also fluidly connected with a first port to the inner pipe and with a second port to the outer pipe of the co-axial tool,
• wherein a temperature difference of the fluid at the power generator and at the co-axial tool drives the power generator to generate energy.
