Li et al. (2023): Attributing the impacts of ecological engineering and climate change on carbon uptake in Northeastern China

Huidong Li, Wanjing Gao, Yage Liu, Fenghui Yuan, Minchao Wu, Lin Meng IN: Landscape Ecology,

The authors aim to detect the location of eco-engineering programs and attribute the impacts of eco-engineering and climate change on vegetation dynamics and carbon uptake in Northeastern China during 2000–2020. They developed a new framework with locations of eco-engineering programs by combining a temporal pattern analysis method and Markov model, and to attribute the impacts of eco-engineering and climate change on vegetation greenness and carbon uptake by combining a neighbor contrast method within a sliding window and trend analysis on the normalized difference vegetation index (NDVI) and gross primary production (GPP).


Tao et al. (2023): Direct air capture of CO2 by metal cation-exchanged LTA zeolites: Effect of the charge-to-size ratio of cations

Zeyu Tao, Yuanmeng Tian, Sze Yiu Ou, Qinfen Gu, Jin Shang IN: AlChE Journal,

The challenge in deploying energy-efficient DAC lies in effective sorbent materials. In this research, the authors comprehensively investigated the DAC behavior of LTA zeolites exchanged with different metal cations (Na+, K+, Mg2+, Ca2+, Mn2+, Co2+, Ni2+, Cu2+, Zn2+, Y3+, La3+, Ce3+, Eu3+, Tb3+, and Yb3+) by both static single-component gas adsorption and dynamic mixture gas adsorptive separation tests.


Kersey et al. (2023): Encapsulation of Nanoparticle Organic Hybrid Materials within Electrospun Hydrophobic Polymer/Ceramic Fibers for Enhanced CO2 Capture

Kyle D. Kersey, Gahyun Annie Lee, Jeffrey H. Xu, Michelle K. Kidder, Ah-Hyung A. Park, Yong Lak Joo IN: Advanced Functional Materials,

Liquid-like nanoparticle organic hybrid materials (NOHMs) consisting of a silica core with ionically grafted branched polyethyleneimine chains (referred to as NIPEI) are encapsulated within submicron-scale polyacrylonitrile (PAN)/polymer-derived-ceramic electrospun fibers. These fibers demonstrate up to ≈2 mmol CO2 g−1 fiber capture capacities in a pure CO2 atmosphere through the nonwoven fibrous networks and the permeability of the OPSZ shell. The hybrid fibers additionally show enhanced capture kinetics under pure CO2 and 400 ppm CO2 conditions, indicating their promising application as a direct air capture platform.


Zhang et al. (2023): Utilization of solid wastes to sequestrate carbon dioxide in cement-based materials and methods to improve carbonation degree: A review

Qi Zhang, Pan Feng, Xuyan Shen, Jinyuan Lu, Shaoxiong Ye, Haochuan Wang, Tung Chai Ling, Qianping Ran IN: Journal of CO2 Utilization 72, 102502,

In this paper, the carbonation potential and the state-of-art carbonation techniques of various solid wastes are comprehensively reviewed, and a pathway to reach net-zero carbon dioxide emission for cement-based materials is proposed. Then physical, chemical and microbiological methods to enhance the carbonation degree of solid wastes are summarized, with both advantages and disadvantages of each method are given. In the end, the challenges and perspectives of the utilization of solid wastes to sequester carbon dioxide in cement-based materials are proposed.


Webinar: Running Tide – Science and Research Efforts in the Ocean-Based CDR Startup Sector

June 7, 2023, 12:00 – 1:00 PM EDT by Ocean Visions

Within this webinar series, Board Member Max Chalfin will present how Running Tide is evaluating the impacts of its ocean-based carbon dioxide removal technologies. Running Tide are in ongoing development and refinement of an CDR system that can amplify and verify multiple natural carbon removal pathways to restore ocean health while maintaining a negative emissions supply chain. Running Tide’s multidisciplinary team of scientists and engineers, in concert with their independent Scientific Advisory board and external partners, developed a Research Roadmap that will help to deploy and scale interventions responsibly.


Webinar: Model Legislation to Advance Ocean Carbon Dioxide Removal Research

by Ocean Visions on youtube, 57 min

In this webinar, Romany Webb, Associate Research Scholar at Columbia Law School and Deputy Director of the Sabin Center for Climate Change Law, describes the existing legal framework for ocean carbon dioxide removal research in the U.S. and highlight key gaps and shortcomings in that framework. She also discusses possible legal reforms to facilitate safe and responsible ocean carbon dioxide removal research. A key focus will be on new model legislation the Sabin Center developed to streamline the permitting of research projects and ensure they are conducted in a scientifically sound way that minimizes risks and maximizes benefits.


Advancing Equitable Deployment of Regional DAC Hubs

by Celina Scott-Buechler, Julia Jeanty, Catherine Fraser, Grace Adcox, Charlotte Scott, Data for Progress, May 2023

Despite the importance of community buy-in, little public opinion research exists on what voters and specific communities think about DAC, and CDR more broadly. Data for Progress worked to fill this gap by conducting community workshops across the country in partnership with local community based organizations and researchers at Stanford University. To date, they have conducted four community DAC workshops, in East Houston, Texas; Beaver County, Pennsylvania; Bakersfield, California; and Rock Springs, Wyoming. In addition to collecting a combination of qualitative and quantitative data through the four workshops, the authors supplemented their findings with a national survey to assess Americans’ attitudes toward DAC and climate infrastructure developments. High-level methodology and results for both of these components are detailed in this memo.


Hospital-Benito et al. (2023): Direct air capture based on ionic liquids: From molecular design to process assessment

D. Hospital-Benito, C. Moya, M. Gazzani, J. Palomar IN: Chemical Engineering Journal 468, 143630,

This work addresses the use of ionic liquids for direct air capture connecting their material design by molecular simulation to process modelling. First, 26 different ionic liquids were designed through quantum chemical calculations and their isotherms were computed to identify those with a positive cyclic working capacity at conditions relevant for direct air capture. Then, the most promising ionic liquids were assessed via process simulations in Aspen Plus.


Qiu et al. (2023): Effect of Biochar on Labile Organic Carbon Fractions and Soil Carbon Pool Management Index

Husen Qiu, Zhuangzhuang Hu, Jieyun Liu, Haiyang Zhang, Weiliang Shen IN: Agronomy 13(5), 1385;

Biochar is useful for soil organic carbon (SOC) sequestration. However, the effects of biochar aging and addition rates on SOC stabilization are unclear. A field experiment with four biochar application rates (0% (control), 1% (LB), 2% (MB), and 4% (HB) of dry fluvo-aquic soil) was conducted. Soil samples were sampled after 8, 12, and 24 months of its application to clarify the question.
