One-third of total world carbon dioxide (CO2) emissions are estimated to come from energy production in power plants. A promising technique, called Carbon dioxide Capture and Storage (CCS), for reducing such emissions, is to capture them before they hit the atmosphere and store the gas underground. The technique requires the CO2 to be separated from the other waste gases before it can be stored, a type of filtration that is expensive and uses chemicals. However, new nanotechnology techniques to fabricate nanoscale thin membranes may lead to a technology that is more effective and costs less, making them competitive for large scale applications, unlike most current membranes. Researchers from the Institute of Materials Research and Institute of Polymer Research, Germany, have developed and manufactured nanometric thin film membranes with record performance, exhibiting unmatched CO2 permeance combined with high selectivity and stability. Research conducted by the team found that their ultra-thin membrane has the potential for carbon capture in coal-fired power plants. Their findings were reported in the September 1 issue of the journal Nanotechnology.
