This article discusses the advantages of using upstream reboilers in geothermal power plants. They offer significant advantages in terms of increased thermal efficiencies and reduced operating costs. For resources with relatively low noncondensible gas content, a comprehensive economic analysis is required to determine the economic attractiveness of upstream reboilers. For steam resources with high noncondensible gas content and for high noncondensible gas brine resources that use a preflash step, upstream reboilers are attractive not only for upstream removal of hydrogen sulfides, but also for a higher overall energy conversion efficiency. In view of the cost of surface reboilers, direct contact reboilers have grat promise.
