Geothermal energization of a non-combustion chemical reactor and associated systems and methods

A reactor system for use with a geothermal heat source, comprising:

• a non-combustion dissociation reactor disposed above the geothermal heat source;
• a working fluid supply system, the supply system including a supply conduit extending to a first portion of the geothermal heat source, the supply system further including a pressure source coupled to the supply conduit to convey the working fluid from a terminal end of the supply conduit into direct contact with the geothermal heat source;
• a working fluid collection system including a collection conduit having a terminal end disposed at a second portion of the geothermal heat source spaced apart from the first portion of the geothermal heat source;
• a separator coupled to the collection conduit to remove from the working fluid a constituent retrieved by the working fluid at the geothermal heat source;
• a heat transfer system coupled between the working fluid collector and the reactor;
• a reactant source coupled to the reactor to provide a donor to the reactor;
• a product removal passage positioned to direct a reaction product from the reactor;
• and
• a working fluid return system coupled between the working fluid collection system and the working fluid supply system.

A method for heating a reactor system with a geothermal heat source, comprising:

• heating a working fluid at the geothermal heat source;
• extracting a constituent from the geothermal heat source with the working fluid;
• separating the constituent from the working fluid;
• transferring heat from the working fluid to a reactor;
• providing a donor substance to the reactor;
• reacting the donor substance at the reactor using the heat provided by the working fluid;
• and
• removing a reaction product from the reactor.

A method for heating a reactor system with a geothermal heat source, comprising:

• directing a working fluid into thermal contact with the geothermal heat source to transfer heat from the geothermal heat source to the working fluid;
• transferring heat from the working fluid to a chemical reactor;
• dissociating a constituent from a donor substance in a non-combustive chemical process at the chemical reactor, using the heat transferred from the working fluid;
• elevating the working fluid in a gas phase from a first elevation to an intermediate elevation higher than the first elevation;
• at the intermediate elevation, changing the phase of the working fluid from the gas phase to a liquid phase;
• under the force of gravity, recirculating the working fluid in the liquid phase from the intermediate elevation and into thermal contact with the geothermal heat source.
