Fluor Solvent Evaluation and Testing New Scope: Technoeconomic Assessment of EEMPA Solvent for CO2 Separations from Natural Gas Combined Cycle Power Plant Final Report, FY24

Summary

This report presents a techno-economic analysis (TEA) of the EEMPA solvent for CO2 capture from natural gas combined cycle (NGCC) power plants, evaluating its performance across various capture rates. The study found that EEMPA achieves a minimum carbon capture cost of $53.7/tonne CO2 at a 90% capture rate, demonstrating 2-4% cost savings compared to Cansolv for capture rates up to 95%. For moderate negative emissions, reducing exhaust gas CO2 to 200 ppmv, EEMPA's marginal capture cost is $545/tonne CO2, making it potentially competitive with direct air capture (DAC) technologies. However, achieving extreme negative emissions (100 ppmv CO2) results in marginal costs exceeding $1,000/tonne CO2. The EEMPA solvent is currently undergoing a 6-month, 0.5MW pilot-scale test at the National Carbon Capture Center (NCCC) in Alabama, which commenced in August 2024, using 2000 gallons of the solvent.
