New technology to monitor and store Carbon dioxide discovered

Q.  Researchers have discovered how to use signature from traces of noble gases for monitoring CO2 stored underground. Noble gases include:
- Published on 07 Oct 15

a. Helium, Neon and Argon
b. Oxygen, Hydrogen and Nitrogen
c. Barium, Uranium and Argon
d. None of the above

ANSWER: Helium, Neon and Argon
 
A fresh technology for monitoring carbon dioxide and storing it to prevent the gas from reaching the atmosphere has been discovered by scientists. This could reduce GHG emissions and lower global warming. The unique traces from signature of noble gases has been used to monitor CO2 stored underground.CO2 emissions from energy generation such as coal burning cause increasing global climate change. CCS or carbon capture and storage techniques are associated with storing the gas in deep aquifers to prevent it from reaching the atmosphere. The new technique discovered can provide a cheap way to fingerprint injected phases in large scale carbon storage projects.
