Carbon dioxide emissions from energy generation, in particular coal burning, contribute to the increasing pace of global climate change. Carbon capture and storage (CCS) techniques aim to store carbon dioxide in depleted oil and gas fields or deep aquifers, preventing it from reaching the atmosphere. Widespread use of CCS in the future could help to reduce global carbon emissions, helping to slow global temperature rise.
The paper’s authors, from the Scottish Universities Environmental Research Centre (SUERC), collected gas samples in 2009 and 2012 from wells at the Cranfield CO2-enhanced oil recovery field in Mississippi, USA.
