A proposed South Texas oil refinery will be collocated with a geothermal power plant, a brine desalination plant and carbon capture and sequestration to create what the developer-owner is describing as the cleanest refinery in the world.
Renewable geothermal energy will power the refinery. Early cycles of geothermal power will be generated using high-temperature brackish water, while later cycles will rely on the refinery’s own carbon-dioxide emissions for power. Captured and pumped deep underground, those emissions will become supercritical from the pressure and heat and then will be drawn back up to drive the geothermal power plant’s turbines.
