Center for American Progress: To Harness the Power of the Ocean To Fight Climate Change, the Biden Administration Needs a Plan

"The recent Sixth Assessment Report from the Intergovernmental Panel on Climate Change showed only narrow pathways to preventing the Earth from warming more than 1.5 degrees Celsius above preindustrial levels. [...] Indeed, even if governments worldwide collectively move to stop using fossil fuels and fully transition to clean sources of energy by midcentury, given the amount of existing GHGs already in the atmosphere, additional measures are needed to achieve negative emissions and keep the Earth within 1.5 degrees Celsius of warming. Negative emissions scenarios can only be accomplished using a combination of mitigation pathways that include 100 percent clean energy as well as methods to draw down and sequester excess carbon dioxide (CO2) from the atmosphere—a process, known as carbon dioxide removal (CDR), that can be either nature- or technology-based."

Otto, Danny; et al. (2021): Exploring Narratives on Negative Emissions Technologies in the Post-Paris Era

Otto, Danny; Thoni, Terese; Wittstock, Felix; Beck, Silke (2021): Exploring Narratives on Negative Emissions Technologies in the Post-Paris Era. In Front. Clim. 3. DOI: 10.3389/fclim.2021.684135.

"Negative Emissions Technologies (NETs)—technologies that remove additional greenhouse gases (GHGs) from the atmosphere—are receiving greater political attention. They are introduced as a backstop method for achieving temperature targets. A focal point in the discussions on NETs are the emission and mitigation pathways assessed by the Intergovernmental Panel on Climate Change (IPCC). Drawing on perspectives from Science & Technology Studies (STS) and discourse analysis, the paper explores the emergence of narratives about NETs and reconstructs how the treatment of NETs within IPCC assessments became politicized terrain of configuration for essentially conflicting interests concerning long-term developments in the post-Paris regime."

Wenger, Ariane; et al. (2021): Public perception and acceptance of negative emission technologies – framing effects in Switzerland

Wenger, Ariane; Stauffacher, Michael; Dallo, Irina (2021): Public perception and acceptance of negative emission technologies – framing effects in Switzerland. In Climatic Change 167 (3-4), p. 533. DOI: 10.1007/s10584-021-03150-9.

"Limiting global warming to 1.5 °C requires negative emission technologies (NETs), which remove carbon dioxide from the atmosphere and permanently store it to offset unavoidable emissions. [...] In 2019, Switzerland adopted a net zero greenhouse gas emissions by 2050 target, which will require the use of NETs. To examine the current Swiss public perception and acceptance of five different NETs, we conducted an online survey with Swiss citizens (N = 693). By using a between-subjects design, we investigated differences in public opinion, perception, and acceptance across three of the most used frames in the scientific literature — technological fix, moral hazard, and climate emergency."

Ainalis, D.; et. al (2021): Net-Zero Solutions and Research Priorities in the 2020s. COP26 Universities Network Briefing

Ainalis, D.; Bardhan, R.; Bell, K.; Cebon, D.; Czerniak, M.; Farmer, J. D.; Fitzgerland, S.; Galkowski, K.; Grimshaw, S.; Harper, G.; Hunt, H.; Jennings, N.; Kehsav, S.; Mackie, E.; Maroto-Valer, M.; Michalopoulou, E.; Reay, D.; Seddon, N.; Smith, S. M.; Smith, T.; Simpson, K.; Stranks, S. D.; Tennyson, E. M.; Uekert, T.; Vera-Morales, M.; Woodcock, J. (2021): Net-Zero Solutions and Research Priorities in the 2020s. COP26 Universities Network Briefing. COP26. UK. Available online at https://www.gla.ac.uk/media/Media_808253_smxx.pdf.

"Key messages:

  • Technological, societal and nature-based solutions should work together to enable systemic change towards a regenerative society, and to deliver net-zero greenhouse gas (GHG) emissions.
  • Prioritise research into efficient, low-carbon and carbon-negative solutions for sectors that are difficult to decarbonise; i.e. energy storage, road transport, shipping, aviation and grid infrastructure.
  • Each solution should be assessed with respect to GHG emissions reductions, energy efficiency and societal implications to provide a basis for developing long-term policies, maximising positive impact of investment and research effort, and guiding industry investors in safe and responsible planning."

C2G (2021): Direct Air Carbon Dioxide Capture & Storage (DACCS). Policy Brief

C2G (2021): Direct Air Carbon Dioxide Capture & Storage (DACCS). Policy Brief. C2G. Available online at https://www.c2g2.net/wp-content/uploads/DACCS-Policy-Brief.pdf.

"Carbon Dioxide Removal (CDR), also known as negative emissions, aims to address the primary driver of climate change by removing carbon dioxide (CO2 ) from the atmosphere and ensuring its long-term storage. Direct Air Carbon Dioxide Capture and Storage (DACCS) is an approach to CDR which may have the potential to contribute to slowing the rate of global warming and help prevent ocean acidification. DACCS should not be confused with Carbon Capture and Storage (CCS). DACCS captures CO2 directly from ambient air and subsequently stores it. CCS stops additional new CO2 from entering the atmosphere at its point of source."

Miao, Yihe; et al. (2021): Operating Temperatures Affect Direct Air Capture of CO2 in Polyamine-Loaded Mesoporous Silica

Miao, Yihe; He, Zhijun; Zhu, Xuancan; Izikowitz, David; Li, Jia (2021): Operating Temperatures Affect Direct Air Capture of CO2 in Polyamine-Loaded Mesoporous Silica. In Chemical Engineering Journal, p. 131875. DOI: 10.1016/j.cej.2021.131875.

"Direct air capture (DAC) is a representative negative emission technology that plays a critical role in achieving carbon neutrality. Understanding the CO2 capture performance of DAC materials in a real-world environment is important to optimize the performance of DAC processes, unfortunately, little is known about their capture efficiency under varying operating temperatures. To this end, we investigated the influence of operating temperatures on the DAC performance of the polyamine-loaded mesoporous silica."

Keller, David P.; et al. (2021): Editorial: The Role of Ocean-Based Negative Emission Technologies for Climate Mitigation

Keller, David P.; Brent, Kerryn; Bach, Lennart T.; Rickles, Wilfried (2021): Editorial: The Role of Ocean-Based Negative Emission Technologies for Climate Mitigation. In Front. Clim. 3. DOI: 10.3389/fclim.2021.743816.

"Until now, the majority of NETs research and development has focused on land-based options such as bioenergy with carbon capture and storage (BECCS). However, ocean-based NETs can potentially also play a significant CDR role. Like their terrestrial counterparts, ocean-based NETs seek to accelerate the uptake of atmospheric CO2 by enhancing natural sinks or by engineering the removal and storage of CO2. Currently there are too many knowledge gaps to fully assess the potential, effectiveness, efficiency, risks and co-benefits, and economic costs of most approaches."

Young, John; et al. (2021): The impact of binary water–CO2 isotherm models on the optimal performance of sorbent-based direct air capture processes

Young, John; García-Díez, Enrique; Garcia, Susana; van der Spek, Mijndert (2021): The impact of binary water–CO 2 isotherm models on the optimal performance of sorbent-based direct air capture processes. In Energy & Environmental Science. DOI: 10.1039/D1EE01272J.

"We present two novel mechanistic co-adsorption isotherm models to describe water's effect on CO2 adsorption and find a good fit to original experimental co-adsorption data. We also show the considerable improvement in predictions of these models when compared to an empirical co-adsorption isotherm model from literature."

Fleming, James Rodger (2021): Excuse Us, While We Fix the Sky: WEIRD Supermen and Climate Intervention

Fleming, J.R. (2021): Excuse Us, While We Fix the Sky: WEIRD Supermen and Climate Intervention. In: Pulé P.M., Hultman M. (eds) Men, Masculinities, and Earth. Palgrave Studies in the History of Science and Technology. Palgrave Macmillan, Cham. https://doi.org/10.1007/978-3-030-54486-7_24

"As alarm over global warming spreads, a radical idea is taking hold. An emerging breed of so-called climate engineers is promoting invasive techniques to cool the planet through albedo modification and so-called “negative carbon emissions” will be necessary. While these proposals seem edgy and exciting, they often test the limits of scientific, technological, and institutional possibility and overlook the political, ethical, and social consequences of managing the world’s climate. Advocates of climate engineering, with vanishingly few exceptions, are Western, Educated, Industrialized, Rich, and Democratic (WEIRD) males with superman complexes. Their views are short-sighted, dangerous, and “barking mad.” This chapter provides historical perspectives, social context, and a gendered analysis of these dangerous proposals."
