Global warming due to greenhouse gas emissions is the most significant challenge to sustaining life on Earth. Many researchers are conducting research to develop sustainable energy technologies. Carbon Capture an‎d Storage (CCS) technologies offer the capability to store carbon dioxide in addition to generating heat an‎d power. Waste-derived fuel can be a potential alternative to fossil fuels for low-capacity power generation. Furthermore, CCS technology applied to waste-derived fuel is a carbon-negative technology that can address the current problem of greenhouse gas emissions. This thesis proposes a novel configuration of a power plant based on Chemical Looping Combustion (CLC) an‎d Chemical Looping with Oxygen Uncoupling (CLOU), utilizing a dual fuel of waste-derived methane an‎d waste-derived hydrogen. The effects of key design parameters, such as the oxygen carrier-to-fuel ratio, the mass fraction of methane in the dual fuel, an‎d the mass fraction of hydrogen in the dual fuel, on the energy an‎d exergy efficiencies are also investigated. The results indicate that supplementing waste fuel with methane increased the Chemical Looping Combustion cycle efficiency from 24.04% for pure waste to 43.07% for pure methane. Similarly, supplementing waste fuel with hydrogen increased the CLC cycle efficiency from 24.04% for pure waste to 44.24% for a 90% hydrogen fuel blend. Furthermore, the analysis of the Chemical Looping with Oxygen Uncoupling process revealed that supplementing waste fuel with methane increased the CLOU cycle efficiency from 24.99% for pure waste to 45.33% for pure methane. Supplementing with hydrogen increased the CLOU cycle efficiency from 24.99% for pure waste to 46.5% for a 90% hydrogen fuel blend. Finally, an exergy analysis an‎d the oxygen carrier-to-fuel ratio for both processes (CLC an‎d CLOU) an‎d both types of dual fuel are presented to identify the best possible options for improving cycle performance.
