CO₂-removal News

This is CDR Ep. 44: The Carbon Drawdown Initiative

by OpenAir on (58 min)

In this episode, the Carbon Drawdown Initiative Founder and CEO Dirk Paessler, and geologist Ingrid Smet talked about Project Carbdown, a long-term field enhanced rock weathering (ERW) field trial, with a focus on the Project’s efforts to develop effective and practical measurement, reporting, and verification (MRV) of ERW as a method of durable carbon removal.


Carbon Capture Summit USA 2022

October 19 – 20, 2022

Industry leaders will meet at Carbon Capture Summit in California, USA to explore next-generation technologies for carbon capture, utilization, storage, and transportation to meet net-zero emissions targets. The key focus for this year’s event will be “Working in collaboration with Industry” by sharing expertise, building capacity, and providing advice and support so that CCUS can play an integral role in reducing carbon emissions. Government agencies, global corporations, research bodies, and non-government organizations committed to learning and adopting CCUS technologies will participate in this event.


Yang at al. (2022): Progress of CCUS technology in the iron and steel industry and the suggestion of the integrated application schemes for China

Yang Yang, Wenqing Xu, Yan Wang, Junru Shen, Yixi Wang, Zanbu Geng, Qiang Wang, Tingyu Zhu IN: Chemical Engineering Journal, 138438,

Here, the research progresses of CCUS technology in the iron and steel industry in China are systematically reviewed, including the projects and novel materials. The maturity and applicability of various technologies were further analyzed by considering the CO2 emission characteristics of different steel-making processes.


Science-Mao et al. (2022): A scalable solid-state nanoporous network with atomic-level interaction design for carbon dioxide capture

Haiyan Mao, Jing Tang, Gregory S. Day, Yucan Peng, Haoze Wang, Xin Xiao, Yufei Yang, Yuanwen Jiang, Shuo Chen, David M. Halat, Alicia Lund, Xudong Lv, Wenbo Zhang, Chongqing Yang, Zhou Lin, Hong-Cai Zhou, Alexander Pines, Yi Cui, Jeffrey A. Reimer IN: Science Advances 8 (31), DOI: 10.1126/sciadv.abo6849

The authors demonstrate new sustainable, solid-state, polyamine-appended, cyanuric acid–stabilized melamine nanoporous networks (MNNs) via dynamic combinatorial chemistry (DCC) at the kilogram scale toward effective and high-capacity carbon dioxide capture.


Green goals require all hands on deck

by Zheng Xin on

„China’s ambitious goal of reaching carbon neutrality by 2060 means the country is set to achieve net-zero emissions in less than 40 years. In addition to shifting toward cleaner energy sources, including solar and wind power, China has also been working on carbon capture, which makes the technology of carbon capture, utilization and storage (CCUS) an essential part of the nation’s green solutions. […] China’s three biggest oil companies-China National Petroleum Corp, China Petrochemical Corp and China National Offshore Oil Corp-have all been actively laying out plans to develop CCUS, which will not only further facilitate the country’s goal to achieve carbon peak and carbon neutrality, but also help boost their domestic oil output.“


The economics of direct air carbon capture and storage

by Eric Williams, Global CCS Institute, 26 pp.

This paper explores the economics of DACCS. The intent is a thought experiment to show how DACCS deployment (based on different cost assumptions) might affect the global energy system through 2065 while maintaining a net-zero CO2 pathway consistent with a 1.5°C global average temperature increase. The analysis relies on the economic model described in the methodology, in which the actors within the energy system are free to pursue least-cost options in meeting the net-zero CO2 pathway.


Wang & Dreisinger (2022): Carbon mineralization with concurrent critical metal recovery from olivine

Fei Wang and David Dreisinger IN: PNAS 119 (32) e2203937119,

Carbon dioxide utilization for enhanced metal recovery (EMR) during mineralization has been recently developed as part of CCUS (carbon capture, utilization, and storage). This paper describes studies on integrating CO2 mineralization and concurrent selective metal extraction from natural olivine.


Bio-oil Sequestration: Prototype Protocol for Measurement, Reporting & Verification

Carbon Direct and Eco-Engineers have developed a prototype protocol (“proto-protocol”) on bio-oil sequestration, the first in a series of science-led draft protocols. In collaboration with Charm Industrial, this analysis focuses on the carbon accounting, life-cycle analysis, and monitoring, reporting, and verification (MRV) foundations for a new carbon removal practice: bio-oil sequestration and geological disposal. It also includes an understanding of the energy requirements in biomass cultivation, harvesting, and conversion as well as a focus on subsurface characterization and operational excellence.
