What is HFOs vs R-134a in ORC Power Plants about?

This document analyzes replacing R-134a as the working fluid in organic Rankine cycle (ORC) power plants with two hydrofluoroolefin (HFO) refrigerants, HFO-1234yf and HFO-1234ze(E). Thermodynamic simulations of a 10 MW geothermal ORC plant currently using R-134a show that directly replacing the working fluid would decrease net power output by 13% for HFO-1234yf and 1% for HFO-1234ze(E). A thermal stability test indicates HFO-1234yf has a maximum feasible working temperature of 200-250°C. The document assess
