Related facts:
- According to the article published by journal “Science” on 10 June 2016, scientists from Iceland have discovered a new way to trap the greenhouse gas (GHG) carbon dioxide (CO2) deep underground by changing it into rock.
- The new way was discovered by Scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions as part of a two year’s pilot program called CarbFix project.
- In the CarbFix project, scientists pumped CO2 and water, 540 metre underground into volcanic rock at the Hellisheidi geothermal power plant.
- In this method, CO2 is dissolved with water (termed as carbonation) is pumped into volcanic rocks called basalts
- Later, the CO2 solidifies turning into a solid mineral (calcite), which can then be stored. In the research it was found that 95% of the gas was captured and converted in two years.
- Britain recently cancelled a major project named “carbon capture & Stored (CCS)”.
