A geothermal energy system utilizes a Catherine Wheel that spins around an axle to produce power. The Catherine Wheel has a plurality of wheel arms extending radially out from the axle. A fin portion extends from the radial portion at an offset angle, to an exhaust end. A first working fluid, such as supercritical carbon dioxide flows through an arm conduit within the wheel arm and second working fluid, such as a simply hydrocarbon mixes with the first working fluid and both flow through a turbine. The turbine is configured within the wheel arm conduit and it turns as the combined working fluids vaporize. The fluids are expelled and the second working fluid may be condensed and recirculated while the first working fluid may be expelled back into a geothermal reservoir. The geothermal energy system efficiently and effectively produces power by using geothermal energy to vaporize a hydrocarbon.

A system includes a subsea geothermal power system. The subsea geothermal power system includes a separator configured to separate a well fluid from a hydrocarbon well into a first fluid flow and a second fluid flow. The subsea geothermal power system also includes a geothermal power plant coupled to the separator. The geothermal power plant is configured to receive thermal energy from the second fluid flow and convert the thermal energy into at least one of electrical energy and mechanical energy. The separator is at least partially powered by the at least one of electrical energy and mechanical energy produced by the subsea geothermal power system.
