Soaking it up

A material that has an exceptional capacity to store gas – and needs only light to release it – could transform carbon-capture technology and dramatically reduce emissions from coal power stations.Monash University and Commonwealth Scientific and Industrial Research Organisation (CSIRO) scientists have created a powerful and cost-effective new tool that as well as capturing and storing carbon dioxide can also release it. The researchers use a metal organic framework, a new class of material that has a very large internal surface area. This means it can store a huge quantity of gas. The researchers have discovered a metal organic framework that is also photosensitive. Because it needs only light similar to concentrated sunlight to release the stored carbon, it avoids the expense and inefficiency associated with current methods of carbon capture.
