Technical and Environmental Assessment of Renewable Dimethyl Ether Production from CO2

A document compares two dimethyl ether (DME) production pathways from CO2 using process simulation and life cycle assessment. The study, authored by Mohamad Kanso, models scenarios using 5,864 kg CO2 from a cement plant flue gas and analyzes impacts from 2020 to 2050. It was last updated on April 20, 2026.

Use Cases

• Compare energy consumption of intensified vs. indirect chemical conversion pathways based on the described kWh and MJ per kgDME metrics.
• Model the environmental impact of defossilizing electricity grids on fuel production based on the reported GWP100 values from 2020 to 2050.
• Benchmark renewable DME production against fossil-based methods using the provided GWP100 impact of 1.2 kg CO2-eq/kg DME for the traditional pathway.

Strengths

• Includes specific quantitative results for two production scenarios, such as DME output (2,929.5 kg/h vs. 2,433 kg/h) and energy consumption (17.80 kWh vs. 22.59 kWh per kgDME).
• Provides detailed environmental impact metrics, including GWP100 values for scenarios from 2020 to 2050, with some showing negative values (e.g., -1.41 kg CO2-eq/kgDME).
• Uses a defined functional unit (production of 1 kg of high-purity DME) for life cycle assessment, enabling standardized comparison.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
