Scientists believe they can achieve carbon capture in their labs through the use of hollow fiber tubes. With these tubes, flue gas is passed through but on the carbon dioxide passes through the tube itself. This is the same process that is used in some water treatment plants, and it could get carbon dioxide away from the other gases so that it can be turned into ready energy.
Currently, there are many ways to separate carbon dioxide, but they are all very expensive and require the use of liquid solvents. The use of these tubes could make this process cost-effective for the energy companies who are doing it and could also allow for energy to be created from these sources at a profit for energy companies.
This means that carbon capture through a hollow membrane tube could be closer to reality than we all think.
