  7. Abstract:
  8. With population growth, increased energy demand, and industrial activity, the amount of environmental pollutant emissions, including carbon dioxide, has risen, leading to climate change. This has resulted in the adoption of policies and decisions aimed at reducing emissions and combating climate change. Currently, the primary source of energy for societies is fossil fuels, and according to forecasts, the complete substitution of these resources in the near future is not feasible. Therefore, appropriate solutions must be considered for this transitional period to manage fossil fuel consumption while mitigating emissions and climate change. Carbon Capture and Utilization is recognized as one of the effective strategies to address climate change and reduce emissions. This technology not only decreases carbon dioxide levels but also leads to the production of higher value-added products, which can have positive economic impacts. These products can be used in chemical, construction, and fuel industries. Therefore, this approach can be implemented in industries through various methods. In this study, Calcium Looping and adsorption methods are examined for capturing emissions from industries located in Tehran. The production of Methanol, as a product for the utilization of Carbon Dioxide and a potential green (clean) fuel additive, is also explored. Considering previous studies in Tehran regarding syngas production from biomass sources, this city is selected as the case study in this research to assess the impact of Methanol chain in local energy system. The study first simulates the processes of Calcium Looping and Methanol production. Then, using an energy supply model for Tehran with the goal of zero-emission under different climate scenarios (Cheetah, Caracal, Hyaena, and Balochi Bear), the inclusion of Methanol as a fuel additive is examined. The research results show that the Carbon Dioxide Capture technology using the Calcium looping method achieves about 93% capture efficiency, and methanol production reaches around 60% efficiency, making it a suitable choice for Methanol production. Furthermore, modeling results indicate that the climate scenarios generally favor the introduction of Methanol as a clean fuel additive. In the Cheetah, Caracal, and Balochi Bear scenarios, emission reductions and improvements in the DALY (Disability-Adjusted Life Years) health index are observed. In the Hyaena scenario, which assumes energy supply without consideration of environmental regulations, no significant positive changes in emissions or the DALY index are seen. From an economic perspective, Methanol production is identified as a high-value product across all scenarios, as its opportunity cost covers a considerable portion of the Carbon Dioxide Capture and Utilization project expenses. These findings indicate that the methanol production chain from biomass sources presents co-benefits in economic, environmental, and health aspects. Moreover, the results derived from the model in scenarios based on national policy documents (Caracal) show that the implementation of Iran’s environmental regulations can to some extent fulfill international climate goals
