Science – Roebroek et al. (2023): Releasing global forests from human management: How much more carbon could be stored?

Caspar T. J. Roebroek, Gregory Duveiller, Sonia I. Seneviratne, Edouard L. Davin, Alessandro Cescatti IN: Science, Vol 380 (6646), pp. 749-753, DOI: 10.1126/science.add5878

The authors integrated global maps of forest biomass and management with machine learning to show that by removing human intervention, under current climatic conditions and carbon dioxide (CO2) concentration, existing global forests could increase their aboveground biomass by up to 44.1 (error range: 21.0 to 63.0) petagrams of carbon. This is an increase of 15 to 16% over current levels, equating to about 4 years of current anthropogenic CO2 emissions.


Nature – Chen et al. (2023): Tree diversity increases decadal forest soil carbon and nitrogen accrual

Xinli Chen, Anthony R. Taylor, Peter B. Reich, Masumi Hisano, Han Y. H. Chen, Scott X. Chang IN: Nature,

The authors analyse Canada’s National Forest Inventory (NFI) database with the help of structural equation modelling (SEM) to explore the relationship between tree diversity and soil carbon and nitrogen accumulation in natural forests. The authors find that greater tree diversity is associated with higher soil carbon and nitrogen accumulation, validating inferences from biodiversity-manipulation experiments. The results highlight that conserving and promoting functionally diverse forests could promote soil carbon and nitrogen storage, enhancing both carbon sink capacity and soil nitrogen fertility.


Van Kooten (2023): Determining optimal forest rotation ages and carbon offset credits: Accounting for post-harvest carbon storehouses

G. Cornelis van Kooten IN: Canadian Agricultural Economics,

A major policy concern is whether forests should be left unharvested to avoid carbon dioxide (CO2) emissions and store carbon, or harvested to take advantage of potential carbon storage in post-harvest wood product sinks and removal of CO2 from the atmosphere by new growth. The issue is addressed in this paper by examining carbon rotation ages that consider commercial timber as well as carbon values. A discrete-time optimal rotation age model is developed that employs data on carbon fluxes stored in both living and dead biomass as opposed to carbon as a function of timber growth.


Cheng et al. (2023): Seasonal and regional changes in terrestrial carbon uptake under an overshoot scenario

Wei Cheng, Lei Huang, Zhu Liu, Jinwei Dong, John C. Moore, Douglas G. MacMartin, Xiangzheng Deng IN: Resources, Conservation and Recycling 195,

The authors examine the seasonal and regional responses of net biome productivity (NBP) and its components to carbon emissions reduction under the SSP5–3.4 overshoot scenario simulated by eight CMIP6 Earth system models. Globally averaged NBP is lower under SSP5–3.4 than under SSP5–8.5, with 102±7 Pg C (51%) less accumulated during 2041 to 2100.


Feng et al. (2023): Functionalized cross-linking mechanism of biochar “adsorption-reaction microunit” on the promotion of new ammonia-based CO2 capture

Dongdong Feng, Yunzhi Li, Peicheng Yan, Yu Zhang, Chunfei Wu, Yalong Zhang, Jianmin Gao, Shaozeng Sun IN: Separation and Purification Technology 317, 123865,

There are limitations faced by traditional capture technology in the absorption rate, ammonia escape and regeneration energy consumption. The functionalized biochar (with a specific surface area of up to 2835.36 m2/g, micropores volume of 77.4 %) was used to enhance the mass transfer process of new ammonia-based (ammonia-ethanol mixed absorbent) CO2 capture by the bubbling absorption experiment system, combined with Monte Carlo simulations, which explored the adsorption and release characteristics of CO2/NH3 molecules in biochar with different pore sizes. The study provides an innovative thought for improving the ammonia-based CO2 capture method and significantly reducing of harmful carbon emissions by biomass energy-carbon capture and storage (BECCS) technology.


Kerner et al. (2023): Carbon dioxide removal to combat climate change? An expert survey on perception and support

Christoph Kerner, Annina Thaller and Thomas Brudermann IN: Environmental Research Communications, DOI 10.1088/2515-7620/accc72 

This study provides insights into academic expert opinions about Bioenergy with Carbon Capture and Storage (BECCS) and Direct Air Carbon Capture and Storage (DACCS). An online survey was conducted to examine how academic experts (N = 172) perceive and to what extent they support BECCS and DACCS.


Saari et al. (2023): Novel BECCS implementation integrating chemical looping combustion with oxygen uncoupling and a kraft pulp mill cogeneration plant

Jussi Saari, Petteri Peltola, Katja Kuparinen, Juha Kaikko, Ekaterina Sermyagina, Esa Vakkilainen IN: Mitigation and Adaptation Strategies for Global Change 28, 21,

The main technical challenges hindering the deployment of BECCS technologies include energy penalties associated with the capture process. This work evaluates the performance of an advanced CO2 capture technology, chemical looping with oxygen uncoupling (CLOU), replacing a conventional fluidized bed boiler in the power boiler role in a large, modern integrated pulp and paper mill. Results from a MATLAB/Simulink reactor model were incorporated in a plant and integration model developed in a commercial process simulation software to quantify the performance of the CLOU-integrated cogeneration plant.


Mamaghani et al. (2023): Adsorption of CO2 using biochar – Review of the impact of gas mixtures and water on adsorption

Zahra Ghanbarpour Mamaghani, Kelly A. Hawboldt, Stephanie MacQuarrie IN: Journal of Environmental Chemical Engineering 11 (3), 109643,

This is a comprehensive review on the use of biochar as a carbon capture adsorbent with a particular focus on the impact of the properties of biochar and feed gas composition CO2 adsorption.


A New Perspective For Scaling BECCS And DAC – BeZero Carbon

by Violet George, on; March 22, 2023

„Despite their central stage in the removal conversation, BECCS and DAC are challenged with unique barriers. As we enter the next chapter of the carbon removal journey, it is crucial that policymakers and investors become more realistic about the barriers ahead. If we break these down and address them through more targeted market and policy support we will better realise gigatonne scale.“
