Greenhouse Gas Removal: Proposed Techniques to Remove Greenhouse Gases from Ambient Air Tim Kruger Oxford Geoengineering Programme Oxford Martin School University of Oxford 18 March 2014
What is geoengineering? • The deliberate large-scale intervention in the Earth’s natural systems to address climate change
Some proposed geoengineering techniques
Prevention is better than a cure… • “The safest and most predictable method of moderating climate change is to take early and effective action to reduce emissions of greenhouse gases” (“Geoengineeringthe Climate: Science, Governance and Uncertainty” Royal Society, 2009)
… but if we can’t prevent it, we sure need a cure Source: “How difficultis it to recover from dangerouslevels of globalwarming?” J A Lowe, C Huntingford, S R B Raper, C D Jones, S K Liddicoat and L K Gohar Environ. Res. Lett. 4 (2009) 014012
The scale of the challenge
Do we have a reverse gear? “Global greenhouse gas emissions need to peak this decade, and get to zero net emissions by the second half of this century” Christiana Figueres (Executive Secretary of UNFCCC, 8 November 2013)) But as is made clear in the UNEP Emissions Gap Report (2012) “To achieve such negative emissions is simple in analytical models but in real life implies a need to apply new and often unproven technologies or technology combinations at significant scale”
Proposed GGR techniques
Implications of GGR for CCS • Some (but not all) GGR techniques assume geological storage capacity potentially massively increased demand for storage sites • GGR storage sites do not need to be proximately located to emissions from point sources
Alternative storage processes • In situ carbonation of peridotite • Carbon stored in biomass • Carbon stored in biochar • Liquid CO2 stored on the ocean seabed • Dissolved Inorganic Carbon stored in the oceans
