Well, a binary cycle geothermal power plant utilizes the low temperature of the primary liquid to generate heat. I found out that they are only 10% to 15% efficient.
Is the continuous flow of the primary fluid a major cause for such inefficiency? From what I understand due to the continuous flow of the primary fluid the secondary fluid is only able to capture a portion of that heat due to continuous flow of primary fluid.
Or is the inefficiency is due to the use of a low boiling point secondary fluid?
Please guide me if I am wrong in my assumptions. I researched a bit but was not able to clear my doubt so though to seek some expert advice.
