Basics of Carbon Capture and Storage


Prof Mike Stephenson
Director Stephenson Geoscience Consulting Ltd; Visiting Professor University of Nanjing and University of Milan

Course Description

GET 2023 delegates can also participate in the short course “Basics of Carbon Capture and Storage: A Course for Geologists, Geological Regulators, Policy Makers and Investors”

This course is for geologists, environmental scientists, and geological regulators, policy makers and investors who are interested in carbon capture and storage. The course will cover: the role of CCS within decarbonisation as an aspect of earth system science; why CCS is necessary; how CO2 is captured in industrial processes and how it can be used industrially; the factors affecting geological storage; how CO2 stores are monitored for leakage; how CCS will be regulated; how CCS will pay for itself; and the social licence for CCS. The course will be delivered in simple non-technical language suitable for non-specialists.

The course satisfies a part of the market that is not currently catered for – the wider science, risks, financing, planning and social licence aspects of CCS. These are issues that are as important as the technical issues (in for example reservoir engineering), in the sense that any of these elements can be a show-stopper for CCS. Although the course will cover the technical geological and engineering aspects of CCS, it will also consider how these technical, policy and science aspects affect planning, regulation and financing of CCS. There are geologists, planners, investors and policy makers in companies, government natural resource and planning departments, investment banks and among NGOs that require this information from an unbiassed technically well informed and up to date source. This course will provide that source.

Participant Profile

The course is designed for geologists, geological planners and regulators, investors and policy makers in energy companies, government natural resource and planning departments, investment banks and NGOs that require information from an unbiassed, technically well informed and up to date source.


No particular prior knowledge needed beyond normal levels of expertise in applied geoscience. As stated above, the course is aimed at geological generalists in energy companies, government natural resource and planning departments, investment banks and NGOs.

I just sat through Mike’s course and have to say – it was amazing. The ease at which Mike presented the material, re-emphasizing, re-visiting key points was masterful. Mike kept the class engaged, and ended with a round of applause and photos! Mike was masterful and I learned a ton!

Mike Stephenson

Prof Mike Stephenson has 25 years experience in energy and geological science and research, including 8 years national level science leadership as the UK’s chief geologist (Executive Chief Scientist and Director of Science and Technology of the British Geological Survey) Mike has been providing geoscience advice to Government for almost 15 years and has an excellent overview of Government policy, industrial activity and funding landscape in applied and energy geoscience, including CCUS, shale gas, geological radioactive waste disposal and geoscience data.

Mike also has expertise in positioning organisations in controversial energy topics e.g. CCUS, shale gas and nuclear. Mike was adviser to Sir Mark Walport (when UK Government Chief Scientist) on shale gas and CCUS in 2016; a member UKRI’s Energy Strategic Advisory Committee 2020 to 2021; and a Member of the UK Government’s Hydrogen Advisory Council 2021. 

Widely recognised as an excellent scientist, he has over 100 peer-reviewed scientific papers including many on CCUS, and ~200 conference abstracts; in addition he was the Chief Editor of an Elsevier science journal for 12 years. 

His science excellence is recognised in his status as professor at four universities. He is Visiting Professor at the University of Nanjing, China, and the University of Milan, Italy. Mike is a well-known communicator of science and has published three single-author popular science books. 

His book on CCUS ‘Returning Carbon to Nature’ is widely seen as the go-to introductory text on CCUS, and reviews of the book include: ‘a tour de force’; ‘excellent review of an important topic’; and ‘conversational prose that opens the book to nontechnical readers’. 

Mike has also delivered high profile lectures, for example in UK Parliament, and has been a science advisor for the BBC’s ‘Horizon’ and ‘Bang Goes the Theory’ programmes.
