ICAP – Innovative CO₂ capture

In post-combustion CO₂ capture, a main bottleneck causing significant reduction in power plant efficiency and preventing cost effectiveness is the low flue gas CO₂ partial pressure, limiting membrane flux, solvent selection and capacity. In pre-combustion CO₂ capture, key bottlenecks are number of processing steps, possible low hydrogen pressure, and high hydrogen fraction in the fuel Global deployment of CO₂ capture is restrained by a general need for prior removal of SO₂. iCap seeks to remove these barriers by developing new technologies with potential for reducing the current energy penalty to 4-5% points in power plant efficiency, to combine SO₂ and CO₂ removal, and to reduce the avoidance cost to 15
