The ORC boiling temperature which maximizes power generation is determined by evaluating the thermodynamic tradeoffs of each temperature. At low boiling temperature, a majority of heat may be extracted from the produced geofluid, however the energy conversion to electricity is at a low efficiency. Thermal efficiency increases with the boiling temperature, as prescribed by the Carnot efficiency. Conversely, at high boiling temperature, the cycle has a higher thermal efficiency, but much of the heat may not be extracted from the produced geofluid. Thus, an iterative method may be used to find the boiling temperature which generates the most power. This process is further described in Section S3 of Adams et al. (2015).
