Solar Chimney Power Plant

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.

This paper intends to improve the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method in view of the traditional TOPSIS method and combines with the current development of Chinese enterprises. By determining the index weights and attributes, it also constructs a new enterprise decision-making method which based on energy saving and greenhouse gas emissions. According to the survey's raw data, this paper not only calculates the energy levels of conventional coal-fired power plant in North China and an integrated gasification gas-steam combined cycle (IGCC) power plant, but also computes their carbon dioxide emissions. The results show that under the same circumstances, the energy consumption of IGCC power plant is lower than that of the conventional coal-fired power plants, has less carbon dioxide emissions, lower carbon intensity and higher carbon productivity. On the basis, using the improved TOPSIS method, the paper calculates the numerical superiority of two schemes and sorts of them, verified the correctness of this construction method.

Early projects of Carbon Capture, Use and Geological Storage (CCUS) could be feasible when fossil fuel-power plants are close to oil and gas reservoirs where CO2-Enhanced Oil Recovery (EOR) technologies are applicable. This Thesis includes estimates for greenhouse gas (GHG) emissions caused in a hypothetical CCUS case with a Natural Gas Combined Cycle power plant (NGCC), which were obtained by using Life-Cycle Assessment (LCA) methodology. This research comprises a comparison with other electricity-generation technologies, including Super Critical Pulverized Carbon (SCPC), NGCC without CO2 capture, geothermal, mini-hydro, wind and nuclear ones. The LCA stages that were undertaken in this study were natural gas supply system, electricity generation, CO2 capture, CO2 transport, EOR operations and environmental monitoring. Three different functional units were used in this study: MJ, kWh and produced oil barrel (bbl). Results indicate that energy produced by the described CCUS system has an environmental impact on climate change of 0.044 kgCO2e/MJ. The NGCC power plant with carbon capture unit would produce 0.177 kgCO2e/kWh, representing about 21% and 36% of the estimated values for the SCPC and NGCC (without CCS) cases respectively, and about 24% less greenhouse gas emissions than the geothermal scenario. The oil produced in the EOR activity has a greenhouse gas emissions of 38 kgCO2e/bbl, 37% less than the historical average in the US. In a “well to well” approach, closing the carbon cycle during primary energy production may become a competitive technology to renewable energy sources.
