Abstract: (2400 Views) |
| Hydropower plants are one of the sources of greenhouse gas emissions due to the need to build a dam reservoir. In this research, using field measurements, the generation of CH4 and CO2 from the reservoirs of hydropower Dams in Karun basin including Karun-3 and Karun-4 and Shahid Abbaspour dams has been investigated. The results showed that Shahid Abbaspour Dam reservoir with emission of 134.5 grams of carbon dioxide equivalent per kWh has the highest greenhouse gas emissions, and then the Karun-4 and Karun-3 dams, respectively, produced 32.87 and 23.92 grams of carbon dioxide equivalent to kilowatt hours of produced electricity are in the next ranks. Also, the comparison of the greenhouse gas emissions of the studied hydropower plants with alternative thermal power plants showed that the studied hydroelectric power plants produced an average of 7.6% of the thermal power plants replacing carbon dioxide equivalent greenhouse gas. This value for Karun-3 is the lowest and for Shahid Abbaspour power plant is the highest value. These results show that with the construction of hydroelectric power plants in Karun basin, more than 92 percent of greenhouse gas emissions have been saved, which is considered to be an optimal performance for the environment. |
