Solar-Driven Steam Topping Cycle for a Binary Geothermal Power Plant

Joshua Dominic McTigue, Guangdong Zhu, Daniel Wendt, Kevin Kitz, Joshua Gunderson

Research output: NRELTechnical Report


Solar-thermal hybridization is a way to boost power generation of geothermal power plants, especially when the geothermal resource cannot supply the design flow or temperature. A new process using a high-pressure steam topping turbine can almost double the conversion rate of solar energy to power compared to the common practice of solar brine heating, and thus improve economic viability.
