This study presents a case study of a novel hybrid solar chimney power plant (HSCPP) design’s performance in the city of Doha, Qatar. The HSCPP construction is similar to the traditional solar chimney power plant (SCPP) but with the addition of water sprinklers installed at the top of the chimney. This allowed the solar chimney (SC) to operate as a cooling tower (CT) during the nighttime and operate as an SC during the daytime, hence providing a continuous 24-h operation. The results showed that the HSCPP produced ~633 MWh of electrical energy per year, compared to ~380 MWh of energy produced by the traditional SCPP. The results also showed that the HSCPP was able to produce 139,000 tons/year of freshwater, compared to 90,000 tons/year produced by the traditional SCPP. The estimated CO2 emission reduction (~600 tons/year) from the HSCPP is twice that of the traditional SCPP (~300 tons/year). The results clearly show that the HSCPP outperformed the traditional SCPP.

“…Recent developments on the SCPP have focused on (1) exploring alternative designs to maximize the power output or (2) improving the overall system efficiency or lowering the capital cost. For example, several articles discussed the integration of the SCP with seawater desalination [17][18][19][20]. The water absorbs heat collected by the solar radiation in the form of heat to vaporize and later be condensed after leaving the turbine and reaching the dew point temperature.…”

“…The new design was able to produce an annual 481,440 kWh of electricity and 123,753 tons of desalinated water at a levelized cost of energy (LCOE) of $1.86/kWh. Kiwan et al [20] studied integrating PV panels with an SCPP. The proposed system used the solar chimney for the direct evaporation of water and extracted the energy from the wet air stream.…”

Integration of Solar Chimney Power Plant with Photovoltaic for Co-Cooling, Power Production, and Water Desalination

et al. 2021

This work explores the technical possibilities of increasing the efficiency of a standard solar chimney power plant (SCPP) by integrating it with photovoltaic (PV) panels. The integration is possible by using the collector circumference to install the PV collectors, which provide a heat sink, allow for the better harvesting of the solar radiation, and increase energy production. The new design led to an increase in the annual electricity production from 380 to 494 MWh and water production from 278 to 326 k tons/year compared with the standard SCPP, marking an increase of 30% and 17%, respectively. The results also show that the integration reduced the greenhouse gas emissions (GHG), the localized cost of energy, and the capital cost of investment by 30%, 36%, and 20%, respectively. The proposed design supports the sustainable replacement of the existing desalination plants with zero operational costs and an excellent reduction in greenhouse gas emissions.

“…Their system achieved water productivity of 2197.4 mL. Kiwan et al 29 used a solar chimney apparatus to increase the incredibly low efficiency of the conventional chimney system, replacing it with a hybrid system capable of power production and water distillation. The hybrid system increased the water productivity of the conventional system from 0.51% to 4.9% at a very low cost of 1.60 US$/m 3 , 46.3% lower than that for the conventional type.…”

Increasing the freshwater productivity of a solar still loaded with CuO nanofluids using vibration motion and cover cooling techniques

et al. 2021

The performance of a single-slope solar still system has been improved with the addition of copper oxide (CuO) nanopowder in water as nanofluid and thermoelectric glass cover cooling combination. The use of vibration further enhances the performance of distillate water as a result of the accelerated heat transfer. In this study, CuO nanofluids loaded the solar still system at volume concentrations of 0.5%, 1%, and 1.5%. The design, fabrication, and testing of the single still were conducted under the local weather conditions of Alexandria, which is located in the northwest of Egypt. The proposed solar still had a base area of 1 m 2 and fitted with four coiled springs, a DC motor, and a photovoltaic (PV) solar panel. The vibration generator was a three-phased, with a 1-HP power motor (220 V, 50 Hz, and 1380 rpm maximum speed) fixed to a compact disk with a small punch for adding masses to generate the un-mass balance forces. The power source for the DC motor was a 250-W PV. The daily output of fresh water during the experimental period was empirically measured under the same climate conditions, and the results were compared with those of a conventional solar still. The daily rates of freshwater productivity were investigated in two cases: (a) under vibration without cover cooling and (b) under vibration with cover cooling at the three given nanofluid volume concentrations. Based on the results, the highest daily freshwater productivity attained with the vibration and cover cooling (at the 1.5% nanofluid volume concentration) 7.
