- CO2 Capture & Utilization

For CCU applications in chemical production, two key criteria stand out: economic viability and significant reduction in CO2 emissions compared with traditional production methods for the same chemical. The findings are corroborated with data from a pilot plant producing 10 kg/day of formic acid. The continuous operability of the process is demonstrated via pilot plant operation for >100 h, achieving a CO2 conversion rate of 82% and producing FA with a high purity of >92 wt %. The proposed process significantly reduces the level of global warming impact by 42% while cutting the production cost by 37%, compared with the conventional process for producing FA. Given the global capacity for formic acid production, the method proposed here could mitigate over 90 kt CO2 emissions annually.
