Project Title: CO₂Capture: Process Using Phase-Changing Absorbents

GE and the University of Pittsburgh are developing a unique CO₂ capture process in which a liquid absorbent, upon contact with CO₂, changes into a solid phase. Once in solid form, the material can be separated and the CO₂ can be released for storage by heating. Upon heating, the absorbent returns to its liquid form, where it can be reused to capture more CO₂. The approach is more efficient than other solvent-based processes because it avoids the heating of extraneous solvents such as water. This ultimately leads to a lower cost of CO₂ capture and will lower the additional cost to produce electricity for coal-fired power plants that retrofit their facilities to include this technology.
