Improving energy recovery efficiency by retrofitting a PCM-based technology to an ORC system operating under thermal power fluctuations

The results showed that the introduction of the PCM-based technology allows the capacity factor to increase from 38% to 52% and the average thermal efficiency to increase from 15.5% to 16.4%. The cost-benefit analysis shows that electric energy priced between 83 and 120 €/MWh could guarantee a payback period between 3 and 5 years.
