(535a) Large-Scale CO2 Utilization for Production of Methanol in Carbon-Intensive Jurisdictions

This study explores the potential of large-scale CO₂ utilization to produce methanol in regions heavily reliant on carbon-intensive energy sources, such Alberta, a western province in Canada. There is an urgent need to mitigate carbon emissions and transition to cleaner energy alternatives. Thus, the main objective is to assess the techno-economic feasibility and environmental impact of using CO₂ hydrogenation processes for methanol synthesis, with a focus on jurisdictions with substantial carbon footprints. The scope extends to evaluating the efficiency improvements, cost implications, and potential carbon reduction.

The methodology includes comprehensive process modeling. The models are developed to represent the methanol synthesis process through CO₂ hydrogenation reactions, including different scenarios and operational parameters. CO₂ is sourced from atmospheric air using direct air capture (DAC), a carbon removal technology. The study focuses on the large-scale production of methanol, 7,000 tonnes per day, via CO₂ hydrogenation, and its comparison to methanol production via conventional natural gas-based technologies, steam methane reforming (SMR) and autothermal reforming (ATR). CO₂ hydrogenation for methanol production includes DAC unit and hydrogen production. This research provides a detailed understanding of the methanol production process, identifies optimal operating conditions, and estimates the potential for carbon emission reduction. A sensitivity analysis is also included to understand the impact of variable feedstock prices, energy costs, and carbon pricing mechanisms on the overall feasibility of the process. The results provide a clear picture of the potential efficiency gains, cost benefits, and environmental impacts associated with hydrogen utilization in methanol production within carbon-intensive jurisdictions.

The study makes a novel contribution by providing region-specific insights and recommendations that would benefit jurisdictions with high carbon footprints. The comprehensive modeling approach and utilization of simulation model offers a robust foundation for evaluating the large-scale production of methanol. It ensures a thorough and accurate analysis, setting the basis for informed decision-making and sustainable industrial practices. The study focuses on establishing a clear link between CO₂ utilization, economic viability, and carbon emission reduction, for the adoption of CO₂ -based technologies in carbon-intensive regions.
