Major boost in carbon capture and storage essential to reach 2°C climate target
Large expansion of carbon capture and storage is necessary to fulfill the Paris Climate Agreement. Yet a new study led by Chalmers University of Technology, in Sweden and University of Bergen, in Norway, shows that without major efforts, the technology will not expand fast enough to meet the 2°C target. And even with major efforts it is unlikely to expand fast enough for the 1.5°C target.

“CCS is an important technology for achieving negative emissions and also essential for reducing carbon emissions from some of the most carbon-intensive industries. Yet our results show that major efforts are needed to bridge the gap between the demonstration projects in place today and the massive deployment we need to mitigate climate change,” says Jessica Jewell, Associate Professor at Chalmers University of Technology in Sweden

A new study titled, ‘Feasible deployment of carbon capture and storage and the requirements of climate targets’, conducted a thorough analysis of past and future growth of CCS to forecast whether it can expand fast enough for the Paris Climate Agreement. The study found that over the 21st century, no more than 600 Gigatons (Gt) of carbon dioxide can be sequestered with CCS.

“Our analysis shows that we are unlikely to capture and store more than 600 Gt over the 21st century. This contrasts with many climate mitigation pathways from the Intergovernmental Panel on Climate Change (IPCC) which in some cases require upwards of 1000 Gt of CO2 captured and stored by the end of the century. While this looks at the overall amount, it’s also important to understand when the technology can start operating at a large scale because the later we start using CCS the lower the chances are of keeping temperature rise at 1.5°C or 2°C. This is why most of our research focused on how fast CCS can expand,” says Tsimafei Kazlou, PhD candidate at University of Bergen, Norway, and first author of the study.

A reminder for those who are morally opposed to any suggestion of CCS:

CARBON DIOXIDE REMOVAL (CDR) refers to technologies, practices, and approaches that remove and durably store carbon dioxide (CO₂ ) from the atmosphere. CDR is required to achieve global and national targets of net zero CO₂ and greenhouse gas (GHG) emissions. CDR cannot substitute for immediate and deep emissions reductions, but it is part of all modelled scenarios that limit global warming to 2°or lower by 2100. Implementation will require decisions regarding CDR methods, scale and timing of deployment, and how sustainability and feasibility constraints are managed.
