“…About the solar power, it is divided into three types of power generation technologies, namely, PV power, solar chimney power plant (SCPP, one technology for the large-scale utilization of solar energy) [20], and CSP (the mechanism of a conventional SCPP is as follows [20]: sunlight transmits through the solar collector cover and heats the ground below; then ambient air enters the solar collector and is heated as it flows along the collector toward its centre, where a chimney is located; then the airflow enters the chimney, due to the pressure created by the density difference between the warm airflow and ambient cold air; finally, with the power conversion unit, the kinetic energy of the airflow is transferred into electrical power). PV power has achieved large-scale commercial development and its cost-benefit has been discussed widely in large numbers of literatures.…”

In 2016, the first batch of concentrated solar power (CSP) demonstration projects of China was formally approved. Due to the important impact of the cost-benefit on the investment decisions and policy-making, this paper adopted the static payback period (SP), net present value (NPV), net present value rate (NPVR), and internal rate of return (IRR) to analyze and discuss the costbenefit of CSP demonstration plants. The results showed the following.(1) The SP of CSP systems is relatively longer, due to high initial investment; but the cost-benefit of CSP demonstration plants as a whole is better, because of good expected incomes. (2) Vast majority of CSP projects could gain excess returns, on the basis of meeting the profitability required by the benchmark yield of 10%. (3) The cost-benefit of solar tower CSP technology (IRR of 12.33%) is better than that of parabolic trough CSP technology (IRR of 11.72%) and linear Fresnel CSP technology (IRR of 11.43%). (4) The annual electricity production and initial costs have significant impacts on the cost-benefit of CSP systems; the effects of operation and maintenance costs and loan interest rate on the cost-benefit of CSP systems are relatively smaller but cannot be ignored.

This study introduces the solar chimney power technology, which is a solar thermal energy system. One of the renewable energy resources, this system is an energy transformation system in which solar energy and wind energy are used together. In this system, the air that is heated with solar energy ensures the production of electric energy by moving upwards with the suction effect of the chimney and rotating the turbine that is placed inside the chimney. In this review, the main principles and characteristics of this system are discussed and the developments on the experimental and theoretical investigations carried out with regard to the solar chimneys around the world especially in recent years are shared with the readers. With the study, it is aimed to provide upto-date information to readers who are interested in this subject.

“…Accordingly, during the research about the hybrid SCPP performance, the daily dynamic profile of power output is a very important factor but has hardly been reported by now. Some transient simulations employed for conventional SCPP [18][19][20] have not been used for analysis of the hybrid SCPP for both waste heat recovery and power output.…”

The numerical simulation of a large-scale hybrid SCPP (an additional waste heat source is connected to the collectorto-chimney transition section) is performed based on a transient model. The daily dynamic profiles of power output, mass flow rate of condensed water and temperature at a representative point for continuous 24 h are obtained, as well as the daily total electricity output and the power difference-to-average ratio (PDAR) defined as the ratio of the peak-valley difference of the daily power profile to the daily average. The effect of effective waste heat flux (EWHF) on the power output by changing the solar radiation intensity is evaluated. Results show that the incorporation of waste heat with enough high heat flux into SCPP causes clear enhancement of the power output. With the increase in the EWHF from 0 to 2 GW, the daily total electricity output increases by 119.99% and the PDAR drops from 1.61 to 0.8. Moreover, the PDAR is smaller for weaker solar radiation. This indicates that enough high waste heat flux helps to flatten the daily profile of the plant power output, especially for weak solar radiation. While low waste heat flux has little influence on the power output and the PDAR.
