Geological carbon storage: Barriers, (mis)conceptions and opportunities - webinar by Oxford Net Zero

In order to keep average global warming to less than 1.5 C by 2050, it is becoming increasingly clear that large quantities of CO₂ will have to be captured and permanently stored. Emissions reductions scenarios are converging to around 15-20% of present day emissions needing to be sequestered, mainly from hard to abate industries like steel, cement, and fertilizer manufacturing. Direct air capture will also need to be a significant fraction of this, to offset emissions from distributed sources of CO₂, such as aviation.
It is clear that an at-scale CO₂ storage industry is now a necessity, and geologic storage will be required to permanently store the CO₂. Whilst dozens of individual full scale projects have been developed over the last 3 decades, and CO₂ has been injected underground in similar quantities for other purposes for almost 70 years, there is still hesitancy and a lack of commitment from industry and government.
This seminar covered the technical, social, and policy factors affecting the upscaling of CO₂ storage, and what is and what isn’t slowing it down. Three speakers gave 10-15 minute presentations on the three topics, which was followed by a discussion and Q&A.
On the panel:
Tom Kettlety, Fellow in Geological Carbon Storage, Oxford Net Zero
Emily Cox, Researcher on Responsible Innovation & Societal Engagement, CO₂RE
David Reiner, Professor of Technology Policy, Cambridge Judge Business School
Steve Smith, Executive Director, Oxford Net Zero and CO₂RE, Chair

Adding it all up globally, by 2050 we will need at least 10 Gt/yr for scope 3 fossil fuel use (25% current emissions), 2 Gt/yr for cement, steel and other industrial emissions, 5 - 9 Gt/year to offset agriculture and 10 Gt/yr to bring down legacy emissions in a timely manner. That’s a requirement of 27 - 31 Billion tonnes per year, 12 in CCS at source and 25 in CDR on top of all the nature-based solutions.
The simple truth is we can’t do without it, so we may as well just get on with it. The sooner we start the less is required

And how do you stop a Lake Nyos disaster?
If you have a well blow-out, the ground-hugging cloud would kill millions of people.
And don’t tell me that well-blowouts are impossible.
