ABSTRACT

A sound measure for the overall efficiency and economy of a power plant is the Energy Return on Investment (EROI). The EROI values could be evaluated for different types of power plants including photovoltaics, wind energy, solar thermal, hydro, natural gas, biogas, coal and nuclear power applying the exergy concept with no “primary energy weighting”. It makes possible to directly compare the overall efficiency of the power plants on a uniform mathematical and physical basis. Pump storage systems, needed for solar and wind energy, have been included in the EROI so that the efficiency can be compared with an “unbuffered” scenario. The results show that nuclear, hydro, coal, and natural gas power systems are one order of magnitude more effective than photovoltaics and wind power. On the other hand, the EROI difference between fossil energy sources and the existing nuclear power plants is rather small and far below the theoretical value of 10000. Based on a new concept of high-temperature nuclear reactors, the Dual Fluid Reactor (DFR) has been shown how to increase the EROI value of the nuclear power and consequently to reduce investment and operating costs of the future power plants.

Keywords: EROI, efficiency of power plants, Dual Fluid Reactor
