The chemical processes and design of a georeactor in the geothermal environment is proposed for direct utilization of geothermal energy resources. Material processing apparatus, comprising high aspect ratio, double and/or multiple tube reactors, were used for chemical reactions installed in a drill hole, with a steam generator supplying hot water and steam for a surface chemical reactor. Chemical processes in the georeactor require mild reaction conditions, accommodating a range of operating conditions, since the georeactor utilizes natural resources that are sometimes difficult to control. A hydrogen generating system, produced from hydrogen sulfide and a high performance photocatalysis, was examined as a case study for use of the georeactor. Hydrogen generation by solar energy from hydrogen sulfide, and recycling of waste sulfur and its compounds using geothermal energy is a potential, environmentally friendly energy supply system.
