Abstract
The capital cost for a representative binary plant using hydrocarbon working fluid and rejecting heat with a cooling tower is $1775/KW of net power output. The cost of a comparable ammonia plant is $1450/KW. If a spray pong is used instead of a cooling tower the cost is reduced to $1250/KW. These costs do not include the wells, geofluid pumps, and piping which will add an additional $300/KW.
