Techno-Economic Analysis of an Integrated E-Methanol Production Plant Utilizing First and Second Generation Biomass Resources

Building upon foundational research utilizing Aspen Plus modeling for e-methanol production from sugar cane and sugar beet biomass, this study advances by incorporating a comprehensive techno-economic assessment (TEA) of an integrated e-methanol production system. The established integrated system converts biomass into ethanol through fermentation and synthesizes e-methanol using both captured CO2 and syngas derived from biomass residue gasification. The approach optimizes dual utilization of CO2 and biomass thereby fostering a circular carbon economy. The TEA quantifies capital expenditures (CAPEX), operational expenditures (OPEX), and levelized costs of energy (LCOE), providing a detailed economic analysis of the potential for commercializing e-methanol. Additionally, a sensitivity analysis is conducted to evaluate the impact of variable factors such as feedstock prices, process yields, and energy costs on the economic outcomes. This sensitivity analysis is crucial for understanding the robustness of the economic model and identifying key leverage points that can significantly affect the project's financial viability. The study aims to explore the potential of utilizing existing agricultural infrastructure for sugar cane and sugar beet to minimize setup costs and expedite market readiness. The system’s capacity to reduce carbon emissions significantly aligns with global sustainability goals. Ultimately, this research provides strategic recommendations to enhance scalability and improve economic outcomes of e-methanol production, promoting a viable path forward in the renewable energy sector. The sensitivity analysis particularly aids in developing robust strategies to mitigate risks associated with economic and market fluctuations.
