Shanin et al. (2024): Predicting the effect of climate change and management on net carbon sequestration in the forest ecosystems of the European part of Russia with the complex of models

Vladimir Shanin, Sergey Chumachenko, Pavel Frolov, Irina Priputina, Daria Tebenkova, Anna Kolycheva IN: Ecological Modelling, 496, 110835, https://doi.org/10.1016/j.ecolmodel.2024.110835

The authors have integrated several ecological models (dynamic stand model FORRUS-S, soil organic matter model Romul_Hum, statistical climate generator SCLISS and process-based forest ecosystem model EFIMOD3) to simulate the ecosystem dynamics at the regional level in several study areas within the forest zone of the European part of Russia. The simulation results reflected both the direct effects of climate change and forest management actions on ecosystem carbon pools, and the indirect effects through changes in species composition. The simulation experiments were spatially detailed at the level of individual forest management units, thereby revealing the influence of habitat conditions on the rate of carbon sequestration under the influence of environmental factors.

Bhati et al. (2024): Ultrafast Formation of Carbon Dioxide Hydrate Foam for Carbon Sequestration

Awan Bhati, Mark Hamalian, Palash V. Acharya, Vaibhav Bahadur IN : ACS Sustainable Chemistry & Engineering, https://doi.org/10.1021/acssuschemeng.4c03809

The auhators report ultrafast formation of carbon dioxide (CO2) hydrate foam without the use of any conventional chemical promoters or mechanical agitation. Our 6× enhancement in the CO2 sequestration rate (based on net gas consumption) results from the high flow rate sparging of CO2 gas in water in an open system (constant gas inflow/outflow) in the presence of magnesium. This approach continuously renews the gas–water–hydrate interface, thereby increasing the growth rate. The CO2 gas consumption rate (for hydrate foam formation) and foam composition (hydrate, CO2 dissolved in water, trapped CO2 gas) are experimentally quantified versus various parameters, including thermodynamic (pressure), CO2 flow-related parameters (flow rate, duration), water composition, and quantity of magnesium. The maximum measured CO2 sequestration rate (time-averaged) of 1276.5 g h–1 L–1 MPa–1 is 6 times higher than the fastest reported instantaneous rate.

Li et al. (2024): Carbon sequestration effects in cementitious composite binder materials under accelerated carbonation: A review

Shaochun Li, Xu Chen, Mengjun Hu, Yongjuan Geng, Shiyu Sui, Shuling Meng, Ling Jin, Weijiu Cui IN: Materials Today Sustainability, 25, 100663, https://doi.org/10.1016/j.mtsust.2023.100663

This paper reviews the latest research progress on the carbon sequestration effects of cement-based binder composite materials under accelerated carbonation methods. It provides a detailed exploration of the influence of cement, admixtures, and additives on the accelerated carbonation outcomes of binding materials. The paper discusses the carbonation capacity of composite binding systems, identifies existing issues, and explores future developments. The aim is to provide practical insights that can enhance the carbon sequestration capability of cement-based binder composite materials. This paper can serve as a technical reference for the construction industry to achieve the goal of “low-carbon emission” through the utilization of accelerated carbonation technology.

Gilmour et al. (2024): Microbially induced calcium carbonate precipitation through CO2 sequestration via an engineered Bacillus subtilis

Katie A. Gilmour, Prakriti Sharma Ghimire, Jennifer Wright, Jamie Haystead, Martyn Dade-Robertson, Meng Zhang, Paul James IN: Microbial Cell Factories, 23, https://doi.org/10.1186/s12934-024-02437-7

Bacteria play a crucial role in producing calcium carbonate minerals, via enzymes including carbonic anhydrase—an enzyme with the capability to hydrolyse CO2, commonly employed in carbon capture systems. This study describes previously uncharacterised carbonic anhydrase enzyme sequences capable of sequestering CO2 and subsequentially generating CaCO3 biominerals and suggests a route to produce carbon negative cementitious materials for the construction industry.

Han et al. (2024): Quantifying the negative effects of dissolved organic carbon of maize straw-derived biochar on its carbon sequestration potential in a paddy soil

Lanfang Han, Beibei Liu, Yu Luo, Liying Chen, Chuanxin Ma, Chao Xu, Ke Sun, Baoshan Xing IN: Soil Biology and Biochemistry, 196, https://doi.org/10.1016/j.soilbio.2024.109500

This study conducted incubation experiments on maize straw-derived 300/450 °C biochar, Biochar dissolved organic carbon (BDOC) extracted biochar residues and BDOC, and applied δ13C analysis to quantify biochar’s mineralization and their priming effects on native soil organic carbon in a paddy soil. The findings proved that BDOC extraction appears a feasible strategy to enhance the short-period carbon sequestration potential of biochar.

Nature – Xu et al. (2024): Dynamics of carbon sequestration in vegetation affected by large-scale surface coal mining and subsequent restoration

Yaling Xu, Jun Li, Chengye Zhang, Simit Raval, Li Guo, Fei Yang IN: Scientific Reports, 14, https://doi.org/10.1038/s41598-024-64381-1

Here, the authors provided a novel approach to assess the dynamics of carbon sequestration in vegetation (VCS) affected by large-scale surface coal mining and subsequent restoration. This approach effectively overcomes the limitations imposed by the lack of finer scale and long-time series data through scale transformation. The findings deepen insights into the intricate relationship between coal resource development and ecological environmental protection.

Stuart et al. (2024): Non-mycorrhizal root-associated fungi increase soil C stocks and stability via diverse mechanisms

Emiko K. Stuart, Laura Castañeda-Gómez, Wolfram Buss, Jeff R. Powell, Yolima Carrillo IN: Biogeosciences, 21, https://doi.org/10.5194/bg-21-1037-2024

Here, with the aim of identifying novel organisms that could be introduced to crop plants to promote C sequestration, the authors assessed the soil C storage potential of 12 root-associated, non-mycorrhizal fungal isolates (spanning nine genera and selected from a wide pool based on traits potentially linked to soil C accrual) and investigated fungal, plant and microbial mediators. They grew wheat plants inoculated with individual isolates in chambers allowing continuous 13C labelling. After harvest, the authors quantified C storage potential by measuring pools of different origin (plant vs. soil) and different stability with long-term soil incubations and size/density fractionation. They assessed plant and microbial community responses as well as fungal physiological and morphological traits in a parallel in vitro study.

Nature – Zhu et al. (2024): Artificial cellulosic leaf with adjustable enzymatic CO2 sequestration capability

Xing Zhu, Chenxi Du, Bo Gao, Bin He IN: Nature Communications, 15, https://doi.org/10.1038/s41467-024-49320-y

In this study, the authors introduce EcoLeaf, an artificial leaf that closely mimics the characteristics of natural leaves. It harnesses visible light as its sole energy source and orchestrates the controlled expansion and contraction of stomata and the exchange of petiole materials to govern the rate of CO2 sequestration from the atmosphere. Furthermore, EcoLeaf has a cellulose composition and mechanical strength similar to those of natural leaves, allowing it to seamlessly integrate into the ecosystem during use and participate in natural degradation and nutrient cycling processes at the end of its life.

Salvador & Doong (2024): Simultaneous achievement of energy recovery and carbon sequestration through municipal solid waste management: A review

Ruben W. Salvador, Ruey-An Doong IN: Chemosphere, 361, 142478, https://doi.org/10.1016/j.chemosphere.2024.142478

With escalating global waste generation, there is an untapped opportunity to integrate carbon dioxide removal (CDR) technologies into existing municipal solid waste (MSW) management processes. This review explores current research on utilizing MSW for CDR, emphasizing its potential for both energy generation and carbon sequestration. The investigation covers three waste management practices: landfilling, waste-to-energy (WtE), and biochar production, revealing two paths for carbon sequestration. First, MSW serves as a feedstock in bioenergy with carbon capture and storage (BECCS), acting as a carbon-neutral resource that avoids fossil fuel and energy crop use, reducing GHG emissions and generating value through energy production. Second, direct storage of organic MSW and its derivatives, like biochar, in various carbon sinks allows for extended sequestration, offering a comprehensive approach to address the challenges of waste management and climate change mitigation.
