A recent study published in the Royal Society of Chemistry highlights the feasibility and sustainability of Carbon Capture and Utilisation (CCU) pathways for formic acid production, comparing emerging thermo-catalytic and electrochemical CO₂ reduction routes against conventional methods.
Using a consistent set of assumptions and scenarios, the research evaluated each pathway in terms of techno-economic viability and environmental impact. The results are promising for the future of low-carbon chemical manufacturing.
KEY FINDINGS:
🔵 Thermo-catalytic pathway outperforms electrochemical reduction in all scenarios with consistently lower Levelised Cost of Production (LCP).
🔵 In the best-case scenario, the thermo-catalytic process achieved an LCP 1.05% lower than the conventional route.
🔵 This same scenario also showed a 38.8% reduction in carbon footprint versus the conventional pathway, and 68.5% lower than the electrochemical route.
🔵 CO₂ source significantly influences the Global Warming Index (GWI) for the thermo-catalytic pathway, while the electricity source plays a greater role in the GWI for the electrochemical route.
This research highlights the potential of thermo-catalytic CCU pathways as a cost-competitive and environmentally superior alternative for formic acid production, signalling a step forward in sustainable industrial practices.
