Economic evaluation of solar thermal hybrid H2O turbine power generation systems

Characteristics and Economics Evaluation of an H2O Turbine Reheat Cycle Power Generation System Based on Oxy-Combustion Method for Utilizing Exhaust Gas of Large Scale MCFC

“…Since the main compositions of the combustion gas become only H 2 O and CO 2 , the separation of CO 2 gas from H 2 O liquid (condensate) can be physically and automatically performed at the outlet of the condenser at the bottoming cycle in the proposed system [3][4][5][6][7][8][9][10].…”

“…The fuel is burned by using O 2 and therefore the combustion reaction takes place in the combustor without N 2 gas. Hence, no thermal NO x is produced in the proposed system when carbon hydride fuel is used [3][4][5][6][7][8][9][10]. Table 2.…”

“…Tables 2 and 3 show major exogenous variables and parameters used for estimating the characteristics of the STPS and the HTPS, and the values used for characteristics simulation, respectively. The values in Tables 2 and 3 are based on previous analyses performed by the authors on a variety of power generation systems, and are considered to be realizable by applying present technologies [3][4][5][6][7][8][9][10]. Table 4.…”

“…Unit power cost, depreciation year, benefit-cost ratio (BCR) and internal income rate of return (IRR), which indicates the average return rate of the invested capital, were adopted in the present research. Table 5 shows the values assumed for performing economic evaluation [3][4][5][6][7][8][9]; for simplicity of conversion, Japanese yen was converted into US dollar at a rate of 100 yen = 1 US $. Regenerator and condenser costs are taken into consideration as an additional facility cost for the HTPS, since these units do not exist in the conventional GT PGSs [1].…”

The feasibility of hybrid solar-biomass power plants in India

“…A small scale demonstration project aiming for completion in June 2012 is TRESERT in Phitsanulok, Thailand. This is a hybrid power plant for tri-generation (electricity, heat and refrigeration) [14].Several other studies have evaluated and optimised CSP power plants based on the criterion of LCOE [15,16]. Considering LCOE and fossil-fuel demand, Montes et al [3] assessed plant performance of a DSG hybrid solar thermal-fossil fuel plant as a function of Solar Multiple (SM), which is defined as the ratio of the solar field mirror aperture area to the size of the field aperture that produces sufficient energy, including thermal and optical losses, to drive a prime mover at its rated capacity at a design irradiance value.…”
