Short Scientometrics of Thermodynamics and Econometrics of Organic Rankine Cycle Operated Concentrated Solar Power Plants for the Distributed-Scale Applications

Abstract

Solar-thermal power plants operating on Solar-
Organic Rankine cycle (S-ORC) are simple and

low-cost. Refrigerant R245FA seems to be more
suitable as working fluid for S-ORC plant.
Concentrated Solar Power (CSP) plant is more
efficient. Along with the Photo-Voltaic (PV) and
technology Solar-Thermal (ST) technology
covers one-third of world’s energy demand. It is
a clean technology and green technology, as
there is no green-house gases (GHG) emission,

and so it is environmental friendly. Hybrid PV-
ST based power plants are also in operation in

many places of states. The levelized electricity
cost (LEC) of CSP is similar to that of PV (both
fall in the range $100–200/MWh depending on
the scale of application) although CSP has an
edge in terms of efficiency.
