Özet:
This study investigates the viability of integrating solar-supported post-carbon capture technology into Iraq's largely gas-based energy matrix. Utilizing solar power to supplement carbon capture schemes, this revolutionary strategy seeks to minimize greenhouse gas emissions while releasing economic potential and improving the efficiency of energy consumption. By extensively analyzing the technical and economic aspects of this integration, this study intends to provide useful information to policymakers and industry players in Iraq in order to enable them to make better-informed decisions towards realizing a sustainable energy future.
In the world of Natural Gas Combined Cycle (NGCC) power plants, it is highly important to have the reduction of CO2 emissions as a high priority to allow for environmental sustainability. The coupling of post-combustion carbon capture technologies is instrumental in reducing greenhouse gas emissions, as it improves the NGCC's environmental image through the reduction of its carbon footprint. This study offers an extensive examination of the integration of solar thermal power into the Besmaya Natural Gas Combined Cycle (NGCC) power plant in Baghdad, Iraq. Utilizing sophisticated process simulation and modelling tools using Aspen Plus software, the study seeks to assess the performance and viability of supplementing the current NGCC plant with solar support for post-carbon capture. The main task of this work is to run a complete simulation of the Besmaya NGCC power plant according to its actual operational status and thereby set the stage for subsequent calculations. Afterward, the Post-Combustion Capture (PCC) plant with solar assistance is simulated and effortlessly connected to existing power networks. For proper assessment of solar thermal power potential in the Baghdad location, the System Advisor Model (SAM) tool is utilized. The incorporation of solar thermal energy into the NGCC power plant is carefully analyzed, and the technical feasibility and performance characteristics of the resulting hybrid system are critically assessed. The research contributes to the discipline by including a valuable observation regarding the technical feasibility and potential benefits of using solar thermal energy in conventional natural gas-based power generation facilities, for the instance of the Besmaya NGCC plant in Baghdad with net plant efficiency of 49.8%, the baseline simulation without carbon capture indicated a strong total power generation capacity of 751 MW. Post-combustion capture integration, on the other
vi
hand, led to a reduction in efficiency to 44 % and a slight decrease in net power capacity to 682 MW. The efficient conversion of nearly 99% of CO2 from the flue gases into methanol highlights the potential of this methodology in reducing greenhouse gas emissions while at the same time yielding a useful chemical feedstock. With this ability, the CO2 production annually was estimated at 2119318 tonnes/year which was minimized to 18,064 tonnes/year (99 % reduction) using MEA absorption system and 16069 tone's/year (99.2%) using CO2-to-Methnol conversion system. The results are meant to guide future actions in the quest for sustainable and efficient energy options, taking into consideration both environmental issues and energy security in the region.
The use of solar energy to split hydrogen from condensate water is a major breakthrough in clean energy technology. Through the energy of the sun, we are able to effectively split the molecule of water into hydrogen and oxygen and thus provide a clean and sustainable fuel source. This method not only reduces the environmental footprint involved in traditional methods of hydrogen production but also taps into a widespread resource—water condensate—that is normally underutilized in industrial processes. With emerging solar water splitting technologies, we can realize the potential for decentralized hydrogen production and enable communities to shift towards a cleaner and more autonomous energy infrastructure.
