  Nowym kierunkiem w procesach separacji dwutlenku węgla stało się w ostatnich latach zastosowanie cieczy jonowych. Niemierzalna prężność par i możliwość dostosowania ich właściwości czyni je idealnymi mediami zastępującymi lotne, korozyjne i toksyczne rozpuszczalniki. Ponadto ciecze jonowe wykazują niską współabsorpcję innych gazów. Dlatego też, możliwe jest selektywne odseparowanie dwutlenku węgla z mieszanin gazowych
