Prats-Salvado et al. (2025): Powering Direct Air Capture: Overview of Existing Concepts and the Overlooked Role of Concentrated Solar Thermal Technologies

Enric Prats-Salvado, Nathalie Monnerie, Christian Sattler IN: Current Sustainable/Renewable Energy Reports, https://doi.org/10.1007/s40518-025-00255-y

Identifying energy sources for DAC that are both scalable and low in carbon intensity remains a major challenge for widespread deployment. Promising options have been identified, such as nuclear and curtailable renewables, as well as a growing interest in power-to-heat and fully electric solutions, and a research gap in the potential of CST technologies to power DAC systems.

Neumann et al. (2025): Riverine Photosynthesis Influences the Carbon Sequestration Potential of Enhanced Rock Weathering

Rebecca B Neumann, Tyler Kukla, Shuang Zhang, David E Butman IN: Frontiers in Climate, doi: 10.3389/fclim.2025.1582786

In terrestrial ERW, crushed rocks are spread on land where they react with CO2 and water, forming dissolved inorganic carbon (DIC) and alkalinity. For long-term sequestration, these products must travel through rivers to oceans, where carbon remains stored for over 10,000 years. Carbon and alkalinity can be lost during river transport, reducing ERW efficacy. However, the ability of biological processes, such as aquatic photosynthesis, to affect the fate of DIC and alkalinity within rivers has been overlooked. The analysis indicates that within a stream-order segment, aquatic photosynthesis uptakes 1% -30% of DIC delivered by flow for most locations. The effect of this uptake on ERW efficacy, however, depends on the cell-membrane transport mechanism and the fate of photosynthetic carbon.

Shangguan et al. (2025): Carbon storage and sequestration of five planting patterns of Picea crassifolia plantations in Qilian Mountains

Yaoyao Shangguan, Hu Zhao, Zhengzhong Zhang, Erwen Xu, Dong Lv, Yanxia Wang, Xingpeng Zhao, Na Wei, Gang Chen, Xingyu Wei, Zhiwen Gao, Mengde Liu IN: Frontiers in Earth Science, doi: 10.3389/feart.2025.1560899

Tree planting patterns play a critical role in influencing soil organic carbon (SOC) dynamics and carbon(C) sequestration potential in forest ecosystems. This study investigated the effects of different planting methods on C stocks in Picea crassifolia plantations located in the shallow mountainous region of the Qilian Mountains, northwest China. Fifteen sample plots were established across five plantation types to quantify biomass, SOC content, and carbon storage in vegetation and soil layers.

Akhmetkaliyeva et al. (2025): Past and present bacterial communities in deglaciating northern latitude catchments reveal varied soil carbon sequestration potential

Saule Akhmetkaliyeva, Andrew P. Dean, Leon J. Clarke, Simon J. Cook, Sharon Ruiz Lopez, Robert B. Sparkes IN: Science of The Total Environment, https://doi.org/10.1016/j.scitotenv.2025.178723

Glacier retreat in northern latitudes exposes new landscapes that may develop soils and ecosystems, which in turn may sequester carbon and serve as a negative climate change feedback. Proglacial soil development and landscape evolution were investigated using transects from three high-latitude glacial systems. Soil samples were analysed for organic carbon (OC) concentration, bacteriohopanepolyol biomarkers (BHPs, membrane lipids that trace major microbial groups), and 16S rRNA gene sequencing.

Devi et al. (2025): Electrodeposition of Carbon-Trapping Minerals in Seawater for Variable Electrochemical Potentials and Carbon Dioxide Injections

Nishu Devi, Xiaohui Gong, Daiki Shoji, Amy Wagner, Alexandre Guerini, Davide Zampini, Jeffrey Lopez, Alessandro F. Rotta Loria IN: Advanced Sustainable Systems, https://doi.org/10.1002/adsu.202400943

Electrochemical seawater splitting is a sustainable approach for hydrogen production and carbon dioxide (CO2) sequestration, producing hydrogen gas at the cathode and oxygen or chlorine gas at the anode. Simultaneously, minerals such as calcium carbonate and magnesium hydroxide precipitate at the cathode, especially when coupled with CO2 injections for the sake of CO2 sequestration. These precipitates are often dismissed as energy-intensive byproducts. However, they have untapped potential as resources for construction, manufacturing, and environmental remediation. Here, a comprehensive experimental investigation is presented into the electrochemical precipitation of minerals in seawater under varying operational conditions. By systematically varying applied voltage, current density, and CO2 flow rate, the conditions that optimize mineral yield and selectivity while minimizing energy consumption are revealed.

Nature – Breure et al. (2025): Revisiting the soil carbon saturation concept to inform a risk index in European agricultural soils

T. S. Breure, D. De Rosa, P. Panagos, M. F. Cotrufo, A. Jones, E. Lugato IN: Nature Communications, https://doi.org/10.1038/s41467-025-57355-y

The form in which soil organic carbon (SOC) is stored determines its capacity and stability, commonly described by separating bulk SOC into its particulate- (POC) and mineral-associated (MAOC) constituents. MAOC is more persistent, but the association with mineral surfaces imposes a maximum MAOC capacity for a given fine fraction content. Here, the authors leverage SOC fraction data and spectroscopy to investigate POC/MAOC distribution, together with SOC changes data over 2009–2018 period, across pedo-climatic zones in the European Union and the UK.

Laatikainen et al. (2025): Sphagnum moss layer growth after restoration of forestry-drained peatlands in Finland

Amanda Laatikainen, Tiina H. M. Kolari, Teemu Tahvanainen IN: Restoration Ecology, https://doi.org/10.1111/rec.70008

Restoration of forestry-drained peatlands aims to restore near-natural hydrology and peat-forming vegetation. Particularly, Sphagnum mosses are important for carbon (C) sequestration through peat accumulation. The authors investigated the new Sphagnum moss layer in 18 restored peatlands circa 10 years after restoration. The sites were monitored for vegetation, water level, and water chemistry. The post-restoration moss layer had grown on average to 14.9 ± 5.2 cm in thickness, measured from peat cores.

Roy et al. (2025): Addition of biofertilizers with crop residue in conservation agriculture improves soil carbon sequestration: a long-term field study

Dewali Roy, A. K. Sinha, S. Rakesh, K. K. Rao, S. Sahoo, P. M. Bhattacharya, B. Mitra, P. Mukhopadhyay, Rajeev Padbhushan IN: Tropical Ecology, https://doi.org/10.1007/s42965-025-00376-x

With the growing importance of adopting biofertilizers management and crop residue addition to combat sustainability issues and carbon (C) sequestration, the present study was conducted in a 12 years long-term rice–wheat cropping system. The study aimed to evaluate the effect of tillage, crop residue, and biofertilizers on C sequestration and different sensitive C pools in the acid alluvial soil of the lower Indo-Gangetic plain of India. For comparison, 3rd and 12th cropping cycle data of eight treatment combinations [tillage (zero tillage (ZT) and conventional tillage (CT)), crop residues, and biofertilizers application] were used. Soil sampling after wheat crop harvest was done at two layers 0–5 cm and 5–20 cm.

Nature – Liu et al. (2025): Co-benefit of forestation on ozone air quality and carbon storage in South China

Zehui Liu, Mi Zhou, Danyang Li, Tao Song, Xu Yue, Xiao Lu, Yuanhong Zhao, Lin Zhang IN: Nature Communications, https://doi.org/10.1038/s41467-025-57548-5

Substantial forestation-induced greening has occurred over South China, affecting the terrestrial carbon storage and atmospheric chemistry. However, these effects have not been systematically quantified due to complex biosphere-atmosphere interactions. Here the authors integrate satellite observations, forestry statistics, and an improved atmospheric chemistry model to investigate the impacts of forestation on both carbon storage and ozone air quality.

Li et al. (2025): Wastewater alkalinity enhancement for carbon emission reduction and marine CO2 removal

Ming Li, Yuren Chen, Riley Doyle, Jeremy Testa, Alexandria Gagnon, Charles B Bott and Wei-jun Cai IN: Environmental Research Letters, DOI 10.1088/1748-9326/adc1e3

This study presents a modeling framework that combines a modern activated sludge model (ASM)-based wastewater treatment plants (WWTP) simulator with an integrated hydrodynamic-biogeochemical-carbonate chemistry model of coastal oceans. The authors evaluated the effects of adding alkalinity either upstream (UpAdd) of the biological treatment stage or downstream at the discharge location (DnAdd) on WWTP carbon emission reduction and marine CO2 removal.
