Patent ID: 8734546

Claim:
A reactor system for use with a geothermal heat source, the reactor system comprising: a chemical reactor; a hydrogen donor supply carrying a hydrogen donor and coupled to the chemical reactor; a products collector positioned to receive dissociated hydrogen from the chemical reactor; a fluid transfer system including: a collection conduit coupled to the geothermal heat source to convey heated working fluid from the geothermal heat source; a heat transfer device coupled to the collection conduit to transfer heat from the working fluid to the reactor; a first conduit portion operatively coupled to the products collector and carrying dissociated hydrogen in a gas phase, the first conduit portion extending to an intermediate location to convey the dissociated hydrogen to the intermediate location, the intermediate location having a higher elevation than an elevation of the chemical reactor; a mixer positioned at the intermediate location and coupled to the first conduit portion to mix nitrogen with the dissociated hydrogen, forming ammonia; a phase change device located at the intermediate location and coupled to the first conduit portion and the mixer to change the phase of the ammonia from the gas phase to a liquid phase; and a second conduit portion coupled to the phase change device and carrying ammonia in the liquid phase.
