CARBON CAPTURE'S FIZZY FUTURE

摘要

For millions of years carbon dioxide has been stored in underground water found in geologic formations saturated with the gas. Findings recently published in the journal Nature use this idea as one way to help bring carbon capture and storage a step closer to reality. One risk around long-term CO2 storage in depleted gas and oil fields has been the possibility of a leak. The researchers' analysis showed underground water is the major carbon dioxide sink in these gas fields and has been for millions of years.
