Chatham House: Cool idea or hi-tech madness?

"As the threat from climate change looms ever larger, growing attention is being paid to proposals that sound as if they come straight from a sci-fi novel. One idea is to spray the stratosphere with particulates to reflect sunlight, thus reducing the temperature of planet Earth."

Sujan, A.; et al. (2019): Direct CO2 capture from air using poly(ethyleneimine)-loaded polymer/silica fiber sorbents

Sujan, A.; Pang, S.; Zhu, G.; Jones, C.; Lively, R. (2019): Direct CO2 capture from air using poly(ethyleneimine)-loaded polymer/silica fiber sorbents. In: ACS Sustainable Chem. Eng. DOI: 10.1021/acssuschemeng.8b06203.

"Direct CO2 capture from atmospheric air is gaining increased attention as one of the most scalable negative carbon approaches available to tackle climate change if coupled with the sequestration of CO2 geologically. [...] In this work, we describe the application of polymer/silica fiber sorbents functionalized with a primary amine rich polymer, poly(ethyleneimine) (PEI), for DAC. Monolithic fiber sorbents composed of cellulose acetate (CA) and SiO2 are synthesized via the dry-jet, wet quench spinning technique."

Climate Institute: Negative Emission Technologies: Silver Bullet or Ethically Ambiguous?

"This paper explores the potential of negative emission technologies (NETs) and highlights the difficulties associated with them. It argues that although these technologies are indeed impressive in theory, the reality shows that they are nowhere near ready to remove carbon at the scale required. This therefore leads to a level of moral ambiguity that could be detrimental to effective climate action. While continued research and development is imperative to global progress – and indeed, technology will be required in the future – the way the utility of NETs is presented threatens to produce an ethical dilemma."

Capito: Capito, Bipartisan Group Reintroduce Bill to Promote Carbon Capture Research, Development

"WASHINGTON, D.C. — U.S. Senators Shelley Moore Capito (R-W.Va.) and John Barrasso (R-Wyo.) today joined with Sen. Sheldon Whitehouse (D-R.I.) to reintroduce S. 383, the Utilizing Significant Emissions with Innovative Technologies (USE IT) Act. The legislation is co-sponsored by EPW Committee Ranking Member Tom Carper (D-Del.), as well as Senators Tammy Duckworth (D-Ill.), Kevin Cramer (R-N.D.), Tina Smith (D-Minn.), Joe Manchin (D-W.Va.), and Mike Enzi (R-Wyo.). "

Clean Energy Wire: Carbon capture technologies not yet mature for large-scale use, German gov says

"Technologies for removing carbon dioxide from the atmosphere are not yet technically mature enough to contribute to climate action, the German government has said in an answer to a parliamentary inquiry by the pro-business party FDP."

MacMartin, D.; et al. (2019): Timescale for Detecting the Climate Response to Stratospheric Aerosol Geoengineering

MacMartin, D.; Wang, W.; Kravitz, B.; Tilmes, S.; Richter, J.; Mills, M. (2019): Timescale for Detecting the Climate Response to Stratospheric Aerosol Geoengineering. In: J. Geophys. Res. Atmos. 41 (3), S. 1738. DOI: 10.1029/2018JD028906.

"Stratospheric aerosol geoengineering could be used to maintain global mean temperature despite increased atmospheric greenhouse gas (GHG) concentrations, for example, to meet a 1.5 or 2 °C target. While this might reduce many climate change impacts, the resulting climate would not be the same as one with the same global mean temperature due to lower GHG concentrations. The primary question we consider is how long it would take to detect these differences in a hypothetical deployment. We use a 20‐member ensemble of stratospheric sulfate aerosol geoengineering simulations in which SO2 is injected at four different latitudes to maintain not just the global mean temperature, but also the interhemispheric and equator‐to‐pole gradients."

Svoboda, T.; et al. (2019): The potential for climate engineering with stratospheric sulfate aerosol injections to reduce climate injustice

Svoboda, T.; Irvine, P.; Callies, D.; Sugiyama, M. (2019): The potential for climate engineering with stratospheric sulfate aerosol injections to reduce climate injustice. In: Journal of Global Ethics 15 (16), S. 1–16. DOI: 10.1080/17449626.2018.1552180.

"Climate engineering with stratospheric sulfate aerosol injections (SSAI) has the potential to reduce risks of injustice related to anthropogenic emissions of greenhouse gases. Relying on evidence from modeling studies, this paper makes the case that SSAI could have the potential to reduce many of the key physical risks of climate change identified by the Intergovernmental Panel on Climate Change. Such risks carry potential injustice because they are often imposed on low-emitters who do not benefit from climate change."
