0001 This invention relates to a method and a system for abating hydrogen sulfide (H<2>S) and carbon dioxide (CO<2>) from H<2>S and CO<2> rich gas mixtures such as geothermal non-condensable gas mixtures (NCG). The H<2>S and CO<2> gas is separated from the remaining gases contained in the H<2>S and CO<2> rich gas mixtures by pressurizing the gas stream and feeding it into an absorption column where H<2>S and CO<2> are preferentially dissolved in a water stream, resulting in water stream rich in H<2>S and CO<2>. The H<2>S and CO<2> rich water stream may then be re-injected into a geological reservoir or used for pH modification of another water stream of geological origin.

A method and system may be used for storing energy in a geothermal system and recovering both the stored energy as well as thermal energy on demand. The geothermal system may include injection and production wells that are hydraulically coupled in a geothermal energy reservoir that behaves as a confined reservoir system with thermal energy transferring to fluid injected into the injection well and removed via the production well.

During an energy storage mode, the injection flow rate exceeds the production flow rate thereby storing energy in the geothermal reservoir. During an energy recovery mode, production backpressure is reduced thereby releasing the stored energy and electricity is generated by removing the thermal energy from the fluid in a heat engine.
