Minimal evaporation gives ionic liquids the edge over amines: since their molecules cannot evaporate, they won't be able to pollute the atmosphere as amines do. In addition, Seddon underlined that, "Unlike amines, ionic liquids are totally recyclable. You can always heat them, separate them from the carbon dioxide, and re-use them again."His hope is that something similar could happen with the CO2 capture technology. In fact, the team just launched a pilot project that uses ionic liquids to filter carbon dioxide, but were not able to reveal where the site was, nor which particular ionic liquid was being used in the process.The competition to discover the best way to tap into the ionic liquids' potential is apparently huge, so they prefer to keep quiet. It all sounds wonderful, until money comes into play. Despite all their qualities, ionic liquids are more expensive than amines to manufacture and work with.But Seddon said that "cost is just the last thing to think about when looking for a solution to such important issues." He pointed out that when QUILL recently discovered a way to remove mercury from natural gas using ionic liquids, they made it commercially viable within few years."Ionic liquids are totally recyclable. You can always heat them, separate them from the carbon dioxide, and re-use them again"
