RESEARCH PAPERS
Review of Economics and Policies of Carbon Dioxide Removal
Oh, S., Greene, J., Honegger, M., & Michaelowa, A. (2025). Review of Economics and Policies of Carbon Dioxide Removal. Current Sustainable/Renewable Energy Reports, 12(1), 6.
Synopsis: Despite growing political support, high costs hinder large-scale deployment of carbon dioxide removal technologies. This review examines the economics of BECCS and DACCS, highlighting that BECCS costs are generally lower, with feedstock sustainability as a key factor, while DACCS costs depend on energy intensity. Recent findings show rising DACCS costs from commercial operations and increasing differentiation in BECCS costs based on feedstock sustainability.
Strategic Design and Multiperiod Optimization under Uncertainty of Solid Sorbent Direct Air Capture Supply Chains in Europe
Crîstiu, D., You, F., d’Amore, F., & Bezzo, F. (2025). Strategic Design and Multiperiod Optimization under Uncertainty of Solid Sorbent Direct Air Capture Supply Chains in Europe. Industrial & Engineering Chemistry Research.
Synopsis: This study presents a mixed-integer linear programming model for optimizing Europe's direct air capture (DAC) supply chains under uncertainty. Considering ambient conditions, energy costs, and emissions, the model ensures cost-efficient and resilient planning. Results suggest that with technology advancements and renewable energy adoption, DAC costs could drop to 121 €/t CO₂ by 2050. The findings provide a strategic framework for policymakers to scale DAC for hard-to-abate emissions.
CO2 uptake estimation in Japan's cement lifecycle
Sawa, D., Yamashita, N., Tanikawa, H., Daigo, I., & Maruyama, I. (2025). CO2 uptake estimation in Japan's cement lifecycle. Journal of Cleaner Production, 486, 144542.
Synopsis: Cement-containing products play a significant role in CO₂ uptake, offsetting emissions from production. This study estimates Japan’s cement lifecycle CO₂ uptake from 1870 to 2070 using dynamic stock-flow analysis. In 2020, uptake reached 2.6 MtCO₂/year, 13.9% of calcination emissions, with in-use concrete absorbing 86.8%. Uptake is projected to peak in the late 2020s before declining. Findings emphasize the need to integrate climate and structural factors into carbon-neutral strategies for cement.
Microbiome manipulation and enhanced weathering stimulate CO2 removal in reforestation
Waring, B., Averill, C., Bidartondo, M., Suz, L., Beerling, D., Crowther, T., ... & Nicholls, C. (2025). Microbiome manipulation and enhanced weathering stimulate CO2 removal in reforestation.
Synopsis: Maximizing forest carbon sequestration is crucial for effective reforestation. This study tested two enhancement strategies—soil microbiome modification and enhanced rock weathering (ERW)—in an 11.5 ha field trial. Over three years, saplings with microbial inoculation grew 7% larger, while ERW boosted aboveground carbon stocks by 27%. Co-deployment of these methods increased carbon sequestration by 69–159 kg C/ha, highlighting their potential to enhance early-stage reforestation efforts.
Unprotected carbon dominates decadal soil carbon increase
Liu, M., Zheng, S., Pendall, E., Smith, P., Liu, J., Li, J., ... & Nie, M. (2025). Unprotected carbon dominates decadal soil carbon increase. Nature Communications, 16(1), 2008.
Synopsis: This study revealed that global soil organic carbon (SOC) storage has increased by 11% from 2000 to 2022, driven by a 21.8% rise in particulate organic carbon (POC), while mineral-associated organic carbon (MAOC) declined by 5.3%. This shift raises the POC/MAOC ratio by 29.1%, indicating lower SOC stability. Land use changes, such as heavy grazing and conventional tillage, reduce SOC in managed ecosystems. To sustain soil carbon sinks, targeted strategies must prioritize preserving and enhancing POC.
Accelerated carbonate weathering by immobilized recombinant carbonic anhydrase
Antonopoulou, I., de Oliveira Maciel, A., Di Giacomo, M., Russo, M. E., Rova, U., Christakopoulos, P., ... & Marzocchella, A. (2025). Accelerated carbonate weathering by immobilized recombinant carbonic anhydrase. Journal of CO2 Utilization, 94, 103050.
Synopsis: Carbonic anhydrase (CA)-promoted CO₂ absorption in alkaline solutions is gaining attention for post-combustion capture. This study immobilized an evolved CA on magnetic nanoparticles (MNPs), enabling efficient enzyme recovery. MNPs-DvCA8.0 enhanced CO₂ capture in accelerated weathering of lime mud, achieving 2.83 g CO₂/g CA—nearly triple the free enzyme’s efficiency. The robust immobilization method ensures enzyme reusability, improving bicarbonate production and process sustainability.
Direct air carbon capture and storage: introduction and implications for power grids
Middleton, A., Zhang, R., & Mercer, S. (2025). Direct air carbon capture and storage: introduction and implications for power grids. Electra, 338.
Synopsis: Direct Air Carbon Capture and Storage (DACCS) is a key CDR technology essential for net-zero goals, with the IEA projecting a rapid scale-up to 980 MtCO₂/year by 2050. This article examines the impact of DACCS expansion on electricity grids, analyzing variations in power demand across different technologies. As deployment accelerates, understanding DACCS energy requirements is crucial for integrating it into low-carbon grids while ensuring cost-effective and sustainable carbon removal.
Past and present bacterial communities in deglaciating northern latitude catchments reveal varied soil carbon sequestration potential
Akhmetkaliyeva, S., Dean, A. P., Clarke, L. J., Cook, S. J., Lopez, S. R., & Sparkes, R. B. (2025). Past and present bacterial communities in deglaciating northern latitude catchments reveal varied soil carbon sequestration potential. Science of The Total Environment, 969, 178723.
Synopsis: Glacier retreat exposes new landscapes that may sequester carbon, influencing climate feedbacks. This study analyzed soil development in recently deglaciated areas in Sweden, Iceland, and Greenland. Organic carbon (OC) concentrations were highest in older moraines, while microbial communities stabilized rapidly, dominated by Acidobacteria, Actinobacteria, and Proteobacteria. Despite similarities in microbial composition, soil development varied, highlighting differing impacts on carbon sequestration.
Is the topsoil carbon sequestration potential underestimated of agricultural soils under best management?
Zhao, Z., Li, T., Cheng, K., & Pan, G. (2025). Is the topsoil carbon sequestration potential underestimated of agricultural soils under best management?. Soil and Tillage Research, 250, 106528.
Synopsis: Enhancing soil carbon sequestration is a key nature-based climate solution, but traditional methods may underestimate SOC stock changes under best management practices (BMPs). This study finds that using a fixed-depth approach can lead to a 25.2% underestimation due to topsoil expansion. A calibrated-depth approach, based on equivalent soil mass, provides more accurate estimates. The study highlights the need for precise soil depth and bulk density measurements for improved SOC monitoring.
Amine-Functionalized Cellulose as Promising Materials for Direct CO2 Capture: A Review
Akaya, H., Lamnini, S., Sehaqui, H., & Jacquemin, J. (2025). Amine-Functionalized Cellulose as Promising Materials for Direct CO2 Capture: A Review. ACS Applied Materials & Interfaces.
Synopsis: This review explores amine-functionalized cellulose as a low-cost, sustainable sorbent for CO₂ capture. It examines advanced synthesis methods that enhance CO₂ affinity, detailing functionalization mechanisms through amine impregnation and grafting under varied conditions. The study also highlights challenges in scaling up, including amine oxidation, stability, and degradation. Addressing these limitations is crucial for the broader adoption of cellulose-based sorbents in carbon capture applications.
Honeycomb-Like Nitrogen-Doped Ultramicroporous Biochar for Efficient and Robust CO2 Capture
Zhang, C., Zhang, D., Zhang, X., Chen, L., Chen, X., Tian, Y., & Wang, L. (2025). Honeycomb-Like Nitrogen-Doped Ultramicroporous Biochar for Efficient and Robust CO2 Capture. Fundamental Research.
Synopsis: In this study, honeycomb-like nitrogen-doped ultramicroporous biochar is synthesized using biomass, urea, and KOH, yielding a material with high nitrogen content and abundant CO₂ sorption sites. It achieves CO₂ sorption capacities of 4.15 mmol/g (298 K) and 5.45 mmol/g (273 K), with strong sorption selectivity and stability over 20 cycles. Its cost-effective synthesis and high performance make it a promising candidate for scalable CO₂ capture applications.

Declining Natural Carbon Sequestration and Accelerating Climate Change | Remove and Reflect Podcast
"In this episode, Mr. Sun (AI character) & Ms. Remove (AI character) discuss a new research article that analyzes the Keeling Curve data to investigate the trend of natural carbon sequestration by the Earth's biosphere. The authors find that after a period of increase, this crucial process of absorbing atmospheric CO2 peaked around 2008 and is now declining. This reduction in natural sequestration means that atmospheric CO2 concentrations will rise more rapidly in response to human emissions. The study emphasizes the close link between the climate and nature emergencies, highlighting the urgent need to restore ecosystems to enhance carbon uptake. Consequently, anthropogenic emissions must decrease even to maintain the current rate of atmospheric CO2 increase.

Could the ocean be our solution to climate change? | The Excerpt | USA TODAY
"What if we can slow climate change by giving the ocean an antacid? It’s called ocean alkalinity enhancement and it’s exactly what researchers have been exploring for the last five years. But it’s only recently that the idea has become a reality. Supporters of the technology say it’s one of the most promising forms of carbon removal to date, a necessary step to meet climate goals even as the world cuts emissions. But in order to truly make a dent in the accumulated carbon in our atmosphere, it will need to be scaled up to massive levels – the question is, can it be done? And can it be done affordably? Jaime Palter, an associate professor of oceanography at the University of Rhode Island, joins The Excerpt to discuss the science and potential of this exciting new weapon in the fight against climate change."

"At COP21 in 2015, the world coalesced around what has come to be known as the Paris Agreement, which aims to limit global warming to well below 2C and pursue efforts towards 1.5C. In 2018, the IPCC published their special report on 1.5C, making it clear that a key milestone of achieving this aim is getting to “net zero.” By 2019, national pledges had started to come in. Starting with the UK, roughly 90 % of the planet is covered by a net-zero pledge of one kind or another.
But what does net zero mean, exactly? Net-zero CO2 emissions, or all greenhouse gases? Absolutely zero carbon (fossil or otherwise in the energy system)? Is nuclear permissible, or should we rely exclusively upon wind, water, and solar power? Once the net zero pledge had been made, the question arose: “Who should pay?” How long have we understood climate change’s anthropogenic and dangerous nature? What, if anything, does this mean about culpability?
Recent publications by, among others, the IEA propose that fossil fuel use should imminently peak, and no further investment should follow–but how realistic is this, how can we reconcile this idea with that of addressing energy poverty, and to what extent is an apparent consensus on “phasing down” coal and phasing out fossil fuels compatible with broader questions of national sovereignty? Suppose we do start focusing on deploying renewable energy. How does intermittency impact the quantum of capacity required to replace or displace conventional thermal power generation? To what extent will EVs reduce oil demand? In all scenarios compatible with a Paris-aligned outcome, the deployment of carbon capture and storage (CCS) and carbon dioxide removal (CDR) technologies emerges as being indispensable–but this technology has consistently failed to overcome barriers to commercialization; how might this barrier be surmounted?"
Addressing Ocean Acidification with Enhanced Rock Weathering & Ocean Alkalinity Enhancement | Global Ocean Health
"For millennia, Indigenous people have depended on marine life, and today, they are taking an active role in restoring our oceans. Daryl Williams, a member of the Tulalip Tribes and an environmental consultant, emphasizes the threats posed by ocean acidification—a direct result of climate pollution—on vital fisheries, including shellfish and salmon, which are central to tribal culture and livelihoods.
With over 2 trillion tons of carbon pollution already in the atmosphere and 40 billion more being added each year, the impacts on marine ecosystems are severe. Mike Robinson, co-founder of Basic Dust (https://basicdust.com/) & PACCLEAN (https://pacclean.org/), discusses the importance of large-scale carbon dioxide removal (CDR) to not only stop further damage but also begin reversing the existing pollution. Enhanced rock weathering (ERW) and ocean alkalinity enhancement (OAE) are emerging as promising solutions, helping to remove carbon while improving water quality and agricultural yields.
The video also highlights a water recycling project in Southern California, where Jeanine Ash, Director and Head of OAE & MRV at Capture6 (https://capture6.org/), describes how brine waste from desalination is repurposed to capture carbon and increase water recovery. These integrated approaches offer multiple environmental and community benefits, reinforcing the idea that addressing climate change is not just about saving the planet — it's about securing our future."
A Blueprint for Biochar Project Success | Biochar Today
"In this episode of This Week in Biochar, we cover the latest developments in biochar research and applications. We discuss a blueprint for successful biochar projects, emphasizing the roles of feedstock, technology, and market demand. We also examine a scientific article on using biochar to remove PFAS, including functionalization techniques like magnetization. Additionally, we explore biochar-hydrogel composites for water purification and in situ remediation. Finally, we touch on biochar's applications in construction, energy storage, and carbon capture."
Simple CO2 Keeling Curve Math Show Earth’s Carbon Sinks Peaking Already in 2008 and Now Declining | Paul Beckwith
"This is an extremely important paper that has thus far not been recognized for its significant contribution to accelerating climate change. Each boreal summer (summer in the northern hemisphere) the vegetation springs to life and captures huge amounts of CO2, drawing down the global atmospheric levels about 7 ppm. This so-called natural sequestration peaked in 2008, and has been declining since then, contributing significantly to accelerating rises in atmospheric Greenhouse Gas levels and thus accelerating climate change."
