New findings will help CO2 storage developmen­t

- By ILONA AMOS

Scottish scientists have found an inexpensiv­e way to monitor safe storage of greenhouse gases from industrial sources.

They said the findings will help in the developmen­t of carbon capture and storage technology, which involves injecting carbon dioxide produced by power stations and factories deep undergroun­d to prevent emissions driving climate change.

In the first study of its kind, researcher­s have discovered that carbon dioxide has a distinctiv­e chemical fingerprin­t, depending on its source. They found gas produced from fossil fuels can be distinguis­hed from that found naturally.

This means gases stored in undergroun­d rock formations would not need to have expensive chemical tracers added in order to monitor that it was effectivel­y contained.
