Membrane catches CO2

Researchers of the Norwegian University for Science and Technology (NTNU) developed a new type of membrane made of plastic material that has been structured by means of nano-technology. The membrane catches CO2 while other waste gasses past freely. This technology can be used for instance in coal fired power plants to reduce their CO2 emissions. It is an effective, eco-friendly and relatively cheap technology. The effectiveness of the membrane is based on the principle that the CO2 molecules in combination with moisture form bicarbonate, which is then quickly transported through the membrane. In this manner, the CO2 is released while the other gases are retained by the membrane. This method is comparable to the way our lungs get rid of CO2 when we breathe. Unfortunately this is a solution only half way there, the other half is what to do with the C02 once captured…
