Abstract
An energy system includes a natural or enhanced geothermal reservoir having a subsurface rock formation and an energy source integrated into the natural or enhanced geothermal reservoir configured to convert heat to energy. The energy source can include at least one of: a hydrogen source included in the subsurface rock formation, a methane or other hydrocarbon gas source, and a dihydrogen sulfide source. The dihydrogen sulfide and the methane or other hydrocarbon gas source can be converted to hydrogen and an associated carbon dioxide or sulfur reaction product can also be sequestered by mineralization in the subsurface rock formation following the conversion.
Claims12
A method of energy production, comprising:
- collecting hydrogen from a first hydrogen source;
- integrating the hydrogen into at least a portion of a geothermal energy system by combusting the hydrogen to produce energy, wherein the geothermal energy system includes a subsurface rock formation;
- and
- collecting additional hydrogen from the subsurface rock formation by injecting one or more of dihydrogen sulfide or carbon dioxide into the subsurface rock formation to react with components in the subsurface formation to form the additional hydrogen;
- and
- integrating the additional hydrogen into at least a portion of the geothermal energy system.
