Zhai et al. (2023): Enhancing Aqueous Carbonation of Calcium Silicate through Acid and Base Pretreatments with Implications for Efficient Carbon Mineralization

Hang Zhai, Qiyuan Chen, Mehmet Yilmaz, Bu Wang IN: Environ. Sci. Technol. 2023, 57, 37, 13808–13817; https://doi.org/10.1021/acs.est.3c03942

Carbon dioxide (CO2) mineralization based on aqueous carbonation of alkaline earth silicate minerals is a promising route toward large-scale carbon removal. In this study, the authors designed and tested three distinctive routes to evaluate the effect of pretreatments under different pH conditions on aqueous carbonation, using amorphous calcium silicate (CS) as an example system. Pretreating CS with high concentrations (100 mM) of HCl (Route I) or NaOH (Route II and III) enhanced their carbonation degrees.

Nature – Lei et al. (2023): Global iron and steel plant CO2 emissions and carbon-neutrality pathways

Tianyang Lei, Daoping Wang, Shijun Ma, Weichen Zhao, Can Cui, Jing Meng, Xiang Yu, Qiang Zhang, Shu Tao, Dabo Guan IN: Nature; https://doi.org/10.1038/s41586-023-06486-7

The highly energy-intensive iron and steel industry contributed about 25% of global industrial CO2 emissions in 2019 and is therefore critical for climate-change mitigation. Here the authors develop a CO2 emissions inventory of 4,883 individual iron and steel plants along with their technical characteristics, including processing routes and operating details (status, age, operation-years etc.). They identify and match appropriate emission-removal or zero-emission technologies to specific possessing routes, or what the authors define thereafter as a techno-specific decarbonization road map for every plant.

Almaraz et al. (2023): Model-based scenarios for achieving net negative emissions in the food system

Maya Almaraz, Benjamin Z. Houlton , Michael Clark, Iris Holzer, Yanqiu Zhou, Laura Rasmussen, Emily Moberg, Erin Manaigo, Benjamin S. Halpern, Courtney Scarborough, Xin Gen Lei, Melissa Ho, Edward Allison, Lindiwe Sibanda, Andrew Salter IN: PLOS Climate, https://doi.org/10.1371/journal.pclm.0000181

Consumers, technology innovation, industry, and agricultural practices offer various degrees of opportunity to reduce emissions and remove CO2. However, a question remains as to whether food system transformation can achieve net negative emissions (i.e., where GHG sinks exceed sources sector wide) and what the capacity of the different levers may be. The authors use a global food system model to explore the influence of consumer choice, climate-smart agro-industrial technologies, and food waste reductions for achieving net negative emissions for the year 2050.

Nicolle (2023): A pathway to negative CO2 emissions by 2050: The contribution of the lime industry to a carbon-neutral Europe

Rodolphe Nicolle IN: ce/papers, 6, 2, https://doi.org/10.1002/cepa.2091

This roadmap presents a reference pathway for the European lime sector to achieve negative CO2 emissions by 2050. It is estimated that by 2030, direct CO2 emissions will be achieved through fuel switch to decarbonized/low carbon energy vectors, as well as the first steps in the deployment of carbon capture utilization and storage (CCUS).

Kane et al. (2023): Bioenergy crop Miscanthus x giganteus acts as an ecosystem engineer to increase bacterial diversity and soil organic matter on marginal land

Jennifer L. Kane, Ronald G. Schartiger, Natalie Kruse Daniels, Zachary B. Freedman, Louis M. McDonald, Jeffrey G. Skousen, Ember M. Morrissey IN: Soil Biology and Biochemistry 186, 109178, https://doi.org/10.1016/j.soilbio.2023.109178

Gaps in the understanding of the mechanisms facilitating soil carbon accumulation under Miscanthus persist, particularly regarding the role of the soil microbiome in facilitating these processes, and how land use histories (e.g. past disturbances) and management strategies (e.g., fertilizer additions) affect these mechanisms. To address these knowledge gaps, the auhtors measured plant performance, soil properties, and microbial parameters over the first three years of Miscanthus establishment across a gradient of land disturbance intensity and different fertilization strategies (none, organic, conventional).

Jahanshahi et al. (2023): Development of bioenergy technologies: A scientometric analysis

Akram Jahanshahi, Myriam Lopes, Miguel Brandão, Eduardo Anselmo De Castro IN: Heliyon, 9, 9, https://doi.org/10.1016/j.heliyon.2023.e20000

This study employs scientometric analysis to survey the progress of scientific development in the field of bioenergy from 1966 to 2022, using ten parameters including publication year, type of document, categories, countries, affiliations, document citations, co-authorship, author citation networks, journal citation networks, and keywords. A total of 51,905 scientific documents were collected from the Web of Science, involving more than 96,000 authors from 162 countries.

[Preprint] Guo et al.: Influence of Ocean Alkalinity Enhancement with Olivine or Steel Slag on a Coastal Plankton Community in Tasmania

Jiaying A. Guo, Robert F. Strzepek, Kerrie M. Swadling, Ashley T. Townsend, Lennart T. Bach IN: EGUsphere, https://doi.org/10.5194/egusphere-2023-2120

Here, the authors used 53 L microcosms to test how coastal plankton communities from Tasmania respond to Ocean alkalinity enhancement (OAE) with olivine (mainly Mg2SiO4) or steel slag (mainly CaO and Ca(OH)2) as alkalinity sources. Three microcosms were left unperturbed and served as a control, three were enriched with olivine powder (1.9 g L−1), and three with steel slag powder (0.038 g L−1). Phytoplankton and zooplankton community responses as well as some biogeochemical parameters were monitored for 21 days.

Wang et al. (2023): Near-Term Suitability Assessment of Deploying DAC System at Airport: A Case Study of 52 Large Airports in China

Feiyin Wang, Pengtao Wang, Mao Xu, Xiaoyu Li, Wei Tan, Hang Li IN: atmosphere, https://doi.org/10.3390/atmos14071099

This study is the first to propose the deployment of direct air capture (DAC) systems at large airports to provide solutions for achieving carbon neutrality in aviation transportation. Here, an estimating model for carbon dioxide (CO2) emissions in the landing and take-off (LTO) phase of large airports was developed, and the suitability of deploying DAC systems at airports was evaluated by the analytic hierarchy process (AHP).

Ganeshan et al. (2023): Bioenergy with carbon capture, storage and utilization: Potential technologies to mitigate climate change

Prabakaran Ganeshan, Vigneswaran V S, Sarath C. Gowd, Rahul Mishra, Ekta Singh, Aman Kumar, Sunil Kumar, Arivalagan Pugazhendhi, Karthik Rajendran IN: Biomass and Bioenergy, 177, 106941, https://doi.org/10.1016/j.biombioe.2023.106941

Bioenergy with carbon capture and storage (BECCS) has certain challenges and limitation which needs to be addressed to make the technology feasible. Concerns about food security, land, water use, and the possibility of large-scale implementation are critical in commercialization. The goal of this critical review is to find the impending obstacles that BECCS is facing, as well as the approaches to overcome them, while also emphasizing the advances in the field over the last decade. Detailed technology assessment is provided for a better understanding.
