Liu, Yayuan; et al. (2020): Electrochemically mediated gating membrane with dynamically controllable gas transport

Liu, Yayuan; Chow, Chun-Man; Phillips, Katherine R.; Wang, Miao; Voskian, Sahag; Hatton, T. Alan (2020): Electrochemically mediated gating membrane with dynamically controllable gas transport. In Science Advances 6 (42). DOI: 10.1126/sciadv.abc1741.

"An electrochemically mediated carbon dioxide concentrator demonstrates proof of concept by integrating the gating membranes with redox-active sorbents, where gating effectively prevented the cross-talk between feed and product gas streams for high-efficiency, directional carbon dioxide pumping. We anticipate our concept of dynamically regulating transport at gas-liquid interfaces to broadly inspire systems in fields of gas separation, miniaturized devices, multiphase reactors, and beyond."

Sapinski, J. P.; et al. (2020): Has it come to this? The promises and perils of geoengineering on the brink

Sapinski, J. P.; Buck, Holly Jean; Malm, Andreas (Eds.) (2020): Has it come to this? The promises and perils of geoengineering on the brink. New Brunswick, Camden: Rutgers University Press (Nature, society, and culture).

"The editors set out this diverse collection of voices not as a monolithic, unified take on geoengineering, but as a place where creative thinkers, students, and interested environmental and social justice advocates can explore nuanced ideas in more than 240 characters."

Rodriguez, Emily; et al. (2020): Tensions in the energy transition: Swedish and Finnish company perspectives on bioenergy with carbon capture and storage

Rodriguez, Emily; Lefvert, Adrian; Fridahl, Mathias; Grönkvist, Stefan; Haikola, Simon; Hansson, Anders (2020): Tensions in the energy transition: Swedish and Finnish company perspectives on bioenergy with carbon capture and storage. In Journal of Cleaner Production, p. 124527. DOI: 10.1016/j.jclepro.2020.124527.

"In the European Pollutant Release and Transfer Register, Sweden and Finland reported 64% and 51% biogenic emissions, respectively, in facilities emitting over 100 kt of carbon dioxide in 2017, while the corresponding collective figure for all European states in the database is 6%. This qualitative study highlights company actors’ perspectives on bioenergy with carbon capture and storage within a Nordic regional context and explores their perspective on emerging tensions in the energy transition."

Feng, Dongdong; et al. (2020): Review of Carbon Fixation Evaluation and Emission Reduction Effectiveness for Biochar in China

Feng, Dongdong; Wang, Shizhang; Zhang, Yu; Zhao, Yijun; Sun, Shaozeng; Chang, Guozhang et al. (2020): Review of Carbon Fixation Evaluation and Emission Reduction Effectiveness for Biochar in China. In Energy Fuels 34 (9), pp. 10583–10606. DOI: 10.1021/acs.energyfuels.0c02396.

"As the world’s largest energy consumer (i.e., 24% of the world) and one of the largest biomass resource reserve countries (i.e., total reserves of 73.42 × 108 t a–1), for China, using biomass to prepare for biochar and store it in soil to realize the “carbon sequestration and emission reduction” is of great significance. This paper explores the physical–chemical properties of biochar and finds out its reason–manifestation–influencing factors for “carbon sequestration reduction”."

Wolf, Martin J.; et al. (2020): A biogenic secondary organic aerosol source of cirrus ice nucleating particles

Wolf, Martin J.; Zhang, Yue; Zawadowicz, Maria A.; Goodell, Megan; Froyd, Karl; Freney, Evelyn et al. (2020): A biogenic secondary organic aerosol source of cirrus ice nucleating particles. In Nat Comms 11 (1), p. 4834. DOI: 10.1038/s41467-020-18424-6.

"Atmospheric ice nucleating particles (INPs) influence global climate by altering cloud formation, lifetime, and precipitation efficiency. The role of secondary organic aerosol (SOA) material as a source of INPs in the ambient atmosphere has not been well defined. Here, we demonstrate the potential for biogenic SOA to activate as depositional INPs in the upper troposphere by combining field measurements with laboratory experiments."

Strassburg, Bernardo B. N.; et al. (2020): Global priority areas for ecosystem restoration

Strassburg, Bernardo B. N.; Iribarrem, Alvaro; Beyer, Hawthorne L.; Cordeiro, Carlos Leandro; Crouzeilles, Renato; Jakovac, Catarina C. et al. (2020): Global priority areas for ecosystem restoration. In Nature. DOI: 10.1038/s41586-020-2784-9.

"Here we develop and apply a multicriteria optimization approach that identifies priority areas for restoration across all terrestrial biomes, and estimates their benefits and costs. We find that restoring 15% of converted lands in priority areas could avoid 60% of expected extinctions while sequestering 299 gigatonnes of CO2—30% of the total CO2 increase in the atmosphere since the Industrial Revolution."

Horton, Joshua B.; et al. (2020): Parametric Insurance for Solar Geoengineering: Insights from the Pacific Catastrophe Risk Assessment and Financing Initiative

Horton, Joshua B.; Lefale, Penehuro; Keith, David (2020): Parametric Insurance for Solar Geoengineering: Insights from the Pacific Catastrophe Risk Assessment and Financing Initiative. In Global Policy. DOI: 10.1111/1758-5899.12864.

"Parametric insurance, which delivers payouts when specific physical indices (such as wind speed) cross predefined thresholds, was recently proposed by two of us as a compensation mechanism for SG with the potential to ease disagreements about the technology and to facilitate cooperative deployment; we refer to this proposal as reduced‐rate climate risk insurance for solar geoengineering, or ‘RCG’. Here we probe the plausibility of RCG by exploring the Pacific Catastrophe Risk Assessment and Financing Initiative (PCRAFI), a sovereign risk pool providing parametric insurance coverage against tropical cyclones and earthquakes/tsunamis to Pacific island countries since 2013."

Manley, Kyle; et al. (2020): Modeling the Dynamic Landscape Evolution of a Volcanic Coastal Environment Under Future Climate Trajectories

Manley, Kyle; Salles, T.; Müller, R. D. (2020): Modeling the Dynamic Landscape Evolution of a Volcanic Coastal Environment Under Future Climate Trajectories. In Front. Earth Sci. 8, p. 437. DOI: 10.3389/feart.2020.550312.

"Olivine weathering is a natural process that sequesters carbon out of the atmosphere, but is now being proposed as a strategy that can be artificially implemented to assist in the mitigation of anthropogenic carbon emissions. We use the landscape evolution model Badlands to identify a region (Tweed Caldera catchment in Eastern Australia) that has the potential for naturally enhanced supply of mafic sediments, known to be a carbon sink, into coastal environments."

Pye, S.; et al. (2020): Modelling net-zero emissions energy systems requires a change in approach

Pye, S.; Broad, O.; Bataille, C.; Brockway, P.; Daly, H. E.; Freeman, R. et al. (2020): Modelling net-zero emissions energy systems requires a change in approach. In Climate Policy, pp. 1–10. DOI: 10.1080/14693062.2020.1824891.

"Energy modelling can assist national decision makers in determining strategies that achieve net-zero greenhouse gas (GHG) emissions. However, three key challenges for the modelling community are emerging under this radical climate target that needs to be recognized and addressed."
