Hong et al. (2026): Carbon sequestration for geological negative emissions of the shale gas value chain in China

Pu Hong, Meiyu Guo, Sai Liang, Wenrui Shi, Yumeng Li and Xi Lu, IN: Nature Communications, https://doi.org/10.1038/s41467-026-68829-y

Carbon sequestration in shale gas operations represents a crucial pathway to achieve Geological Negative Emissions, which is essential for global 1.5 °C targets. However, the emissions reduction potential and economic viability of this approach in China’s shale gas value chain remain unclear. This study quantifies the potential for transforming China’s shale gas value chain from an emission source to a carbon sink, while revealing spatial heterogeneity in economic feasibility.

Herbermann et al. (2026): Assessing BECCUS impacts on the SDGs through a value chain assessment for climate mitigation and energy transition

Joris Herbermann, Bob van der Zwaan and Drielli Peyerl, IN: Sustainable Production and Consumption, https://doi.org/10.1007/s43937-025-00121-4

As the urgency for climate mitigation intensifies, Bioenergy with Carbon Capture, Utilization, and Storage (BECCUS) is emerging as a prominent negative emissions technology with significant potential to contribute to carbon removal efforts and sustainable energy systems. This work analyses whether the BECCUS value chain can support progress toward the 2030 Agenda by assessing the impacts across the 17 Sustainable Development Goals (SDGs) and their 169 targets. By applying the Value Chain Assessment methodology, the authors assess the BECCUS value chain across five segments. Each segment is evaluated in terms of its positive or negative influence, as well as its direct or indirect impact, and in terms of its temporality. A new step is introduced to complement this assessment by identifying the Political, Economic, Social, Technological, Legal, and Environmental (PESTLE) enablers for formulating policy recommendations.

Li et al. (2026): Accelerating widespread adoption of direct air capture based on system perspective: Thermodynamic limits, geographical deployment, and clean energy integration

Chunfeng Li, Shuai Deng, Xiangkun Elvis Cao and Shuangjun Li, IN: Renewable and Sustainable Energy Reviews, https://doi.org/10.1016/j.rser.2026.116702

Direct Air Capture (DAC) is a critical negative emission technology essential to achieve the global climate targets. However, its widespread adoption is hindered by a multitude of technical, economic, deployment, and sustainability challenges. The purpose of this review is to bridge this critical gap by deconstructing the challenges and opportunities for DAC through a novel, three-tiered analytical framework. Basically, the fundamental challenge of DAC lies in the high energy consumption and low exergy efficiency associated with CO₂ enrichment from its low atmospheric concentration.

Kirppu et al. (2025): District heating with negative emissions – Direct Air Carbon Capture and Storage combined with Small Modular Reactors

Heidi Kirppu, Miika Räma, Esa Pursiheimo, Kati Koponen and Tomi J. Lindroos, IN: Carbon Capture Science and Technology, https://doi.org/10.1016/j.ccst.2025.100533

Achieving Paris Agreement targets for climate change mitigation requires an urgent shift away from fossil fuels. In addition, negative emissions by permanently removing carbon dioxide from the atmosphere are required. Both targets require substantial amounts of carbon neutral electricity and heat production. While electricity can be produced and transferred over long distances, the heat production needs to be local. This study investigates an energy system integrating both carbon neutral heat production and carbon dioxide removal from the atmosphere.

Li et al. (2025): Innovative performance evaluation and process simulation of a 550 MW staged, pressurized oxy-biomass combustion power plant for negative carbon emissions

Xiangdong Li, Hui Lin, Guan Wang, Gaofeng Dai, Yongqiang Chen, Yong Luo, Bin Liu, Jiaye Zhang, Richard L. Axelbaum and Xuebin Wang, IN: Renewable Energy, https://doi.org/10.1016/j.renene.2025.124534

Bioenergy with carbon capture and storage (BECCS) technology is crucial for improving carbon capture efficiency but faces challenges due to high electricity costs. Staged, pressurized oxy-combustion addresses this by efficiently recovering latent heat from flue gas within the steam Rankine cycle, improving net plant efficiency in power plants. Integrating biomass with this technology holds promise for reducing fossil fuel consumption and achieving negative carbon emissions. However, the performance of staged pressurized oxy-biomass combustion (Bio-SPOC) has not been studied yet. This study used ASPEN Plus to analyze the performance of a 550 MW staged, pressurized oxy-biomass combustion power plant.

Lu et al. (2025): Earth system responses under a global 2 °C-target scenario aligned with China’s carbon neutrality pledge

Yixiong Lu, Lei Jin, Junting Zhong, Xiaoye Zhang, Yanwu Zhang, Fanghua Wu, Fang Zhang, Zhili Wang, Jie Zhang, Xiaoge Xin, Tongwen Wu, Deying Wang, Da Zhang, Tianpeng Wang and Wei Hua, IN: Environmental Research Letters, https://doi.org/10.1088/1748-9326/adfbfb

Achieving the Paris Agreement’s 2 °C target demands regionally tailored climate policies and proven negative emission strategies. This study uses a novel SSP2-com scenario that integrates updated emissions trajectories, China’s carbon neutrality pledge, and mid-to-late 21st century CDR deployment to assess Earth system responses.

Some nations want to remove more pollution than they produce. That will take giving nature a boost

by David Keyton on apnews.com, December 11, 2023

“As countries at the COP28 climate talks are wrangling over ways to lower their greenhouse gas emissions, a Danish-led group of countries has decided to set the ultimate goal: to remove more carbon dioxide, the main source of global warming, from the atmosphere than they emit. The Group of Negative Emitters was launched Sunday in Dubai by Denmark, Finland and Panama, and aims to reach that goal by slashing emissions, protecting and expanding forests, and investing in new technologies. Panama has already reached the goal with its vast forests that act as a huge carbon sink. Finland and Denmark hope to achieve this by 2035 and 2045, respectively.”

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.
