Diagram Binary Geothermal
Summary
caption: "Diagram showing how electricity is generated from a moderate-temperature hydrothermal system using a 'binary' system. The geothermal water is used to boil a second fluid (isobutane in this example) whose vapor then drives a turbine generator. The wastewater is injected back into the subsurface to help extend the useful life of the hydrothermal system."
