Scotland-Malaysia study highlights role of subsurface saline aquifers in safe and secure CO2 storage


A new study by scientists from Scotland and Malaysia has provided insights into the role of natural mechanisms within rocks deep below ground for securely storing anthropogenic carbon dioxide (CO2).

The team from the University of Edinburgh and Universiti Teknologi PETRONAS carried out a comprehensive review of past, recent and ongoing developments in CO2 storage in saline aquifers. 

Their findings have boosted understanding of how different trapping methods can maximise the security and storage potential of any CO2 storage site, which will be of value to countries seeking to develop carbon capture and storage (CCS) projects.

CCS technology, if delivered at scale alongside other measures, can substantially reduce society’s carbon emissions from different sectors, such as industry and power generation, and help tackle climate change.
