Venue: Gordon Aikman Lecture Theatre, 32 George Square, Edinburgh, EH8 9LH
Talk by Dr Stuart Gilfillan, University of Edinburgh, as part of Our Changing World series
Driven by the increasing threat of global climate change, there is an urgent need to rapidly decarbonise the global energy system. Whilst renewable energy has made strong progress in the electricity sector, fossil fuels continue to be the world’s dominant source of energy. Carbon Capture and Storage (CCS) is the only currently available technology that can directly reduce CO2 emissions caused by fossil fuel combustion. The technology involves capture of CO2 at the point source, followed by transport and secure storage of the CO2 into a deep geological reservoir.
This lecture will explore how identifying the chemical fingerprints in natural gases can be used to prove that secure storage of CO2 over millions of years is probable, how these fingerprints can identify the mechanisms of storage that operate in nature and how engineered CO2 storage can be monitored in order to ensure secure storage and effective emissions mitigation.
Following the talk, there will be a Q&A
Stuart Gilfillan is a Senior Lecturer in Geochemistry in University of Edinburgh's School of Geosciences.
