CCS tracking technology tested in US
Carbon capture and storage (CCS) in the US has taken a step forward recently as scientists have developed a system of tracking carbon dioxide underground.
Tests were successfully undertaken at a site in New Mexico by researchers from the National Energy Technology Laboratory (NETL), which involved using colourless liquid tracers to track the gases' movements.
The technology was said by NETL to be "invaluable", as it allows scientists to measure storage capacity, injection capacity and flow rates.
It is being hailed as a step forward as the US attempts to curb its green house gas emissions. Targets set out in the controversial climate bill are for a cut of 17 per cent by the year 2020.
Brian Strazisar, a physical scientist at the National Energy Technology Laboratory in Pittsburgh, told the Associated Press that the tracers will help with some of the barriers which currently hinder CCS.
"There is going to be some sort of requirement that we verify that the carbon dioxide is going where we expect it to and that it's not going back into the atmosphere or into geologic zones that weren't intended," he explained.
