Abstract:
1. A system for cooling permafrost, comprising: a first conduit coupled to a source of sub-surface donor gas at a first permafrost region; a chemical reactor coupled to the first conduit to receive the donor gas and conduct a non-combustion reaction that dissociates the donor gas into first and second constituents; a second conduit coupled to the reactor to receive the dissociated first constituent; a first heat exchanger coupled to the second conduit to receive the dissociated first constituent, at least a portion of the first heat exchanger being exposed to ambient air to cool the first constituent; and a sub-surface second heat exchanger coupled to the second conduit to receive the cooled first constituent from the first heat exchanger, the second heat exchanger being positioned to transfer heat from a second permafrost region to the cooled first constituent.
