Project: High-efficiency, Low-cost, Additive-manufactured Air Contactor (Creare)

"Reducing the cost of CO2 removal from the air requires developing a new contactor, which captures CO2 so it can be recovered, concentrated, and stored. Creare aims to develop a contactor using Creare’s low-cost additive manufacturing methods. Creare will also incorporate a low-cost, durable sorbent that captures CO2 molecules from ambient air and releases CO2 for storage when heated to moderate temperatures. The contactor is designed for wind-driven operation, which reduces cost by eliminating the need for large arrays of fans to blow air through the system."

Project: Wind-Driven Direct Air Capture System Using 3D Printed, Passive, Amine-loaded Contactors (Georgia Institute of Technology)

"Georgia Institute of Technology aims to develop a simple, scalable, and modular device that can remove CO2 from the atmosphere. The device will be designed such that ambient wind is sufficient to contact the CO2-laden air with the materials that filter CO2 out. The filtered CO2 will then be concentrated using localized electric heating, which allows the device to be easily deployed and integrated with renewables or the existing electrical grid. The proposed technology is driven solely by electricity with only two moving parts (a damper and a vacuum pump), which dramatically simplifies scale-up and deployment compared with incumbent CO2 removal approaches."

Project: Electrochemical Direct Air Capture of CO2 using Redox-active Textiles (University of Michigan)

"The University of Michigan, in collaboration with the University of Massachusetts Amherst, will develop a technology that captures CO2 from the atmosphere using an electrochemical approach, rather than the temperature swing cycle which is typically powered by fossil fuel combustion. The team’s concept is a pH swing cycle that changes conditions between basic and acidic to capture and release CO2, respectively. Direct air capture (DAC) of CO2 by inexpensive renewable electricity could reduce the cost and improve the efficiency of DAC. The team aims to optimize the design of the cycle to achieve high rates of CO2 separation at low energy inputs."

Project: Oxide Looping for Direct Air Capture (Kleinman Center for Energy Policy)

"This project, underway at Pennovation, explores which reactive materials best remove CO2 from the air. In addition to selecting and testing different materials for effective mineral carbonation, the research team is also comparing CO2 uptake based on exterior conditions like air temperature and humidity."

Akimoto, Keigo; et al. (2021): Climate change mitigation measures for global net-zero emissions and the roles of CO2 capture and utilization and direct air capture

Akimoto, Keigo; Sano, Fuminori; Oda, Junichiro; Kanaboshi, Haruo; Nakano, Yuko (2021): Climate change mitigation measures for global net-zero emissions and the roles of CO2 capture and utilization and direct air capture. In Energy and Climate Change, p. 100057. DOI: 10.1016/j.egycc.2021.100057.

"Many existing scenario studies show the need for large amounts of biomass energy with carbon dioxide capture and storage (BECCS) to achieve net-zero emissions, requiring high mitigation costs. This study provides comprehensive and cost-efficient technological portfolios for both energy supply and demand, and reveals the roles of carbon dioxide utilization (CCU) and direct air capture (DAC) for achieving global net-zero emissions by using a technology-rich global energy systems and climate change mitigation model which can assess them comprehensively, while considering several kinds of uncertainties. According to the analyses, DAC will be able to dramatically reduce emission reduction costs and alleviate dependence on BECCS. There are no feasible solutions for temperature increases below 1.5 °C in 2100 with 66% achievability under a temperature overshoot pathway unless DAC is used. Carbon free or nearly carbon free hydrogen plays important roles for net-zero emissions, and CCU helps increase the usability of hydrogen via synthetic fuels, and thus contributes to net-zero emissions. The relationships between DAC and CCU are very complex; the reductions in marginal abatement costs of carbon dioxide (CO2) due to DAC will reduce the roles of CCU around 2050 for many of the pathways to net-zero emissions. Meanwhile, for deeper reductions of CO2 emissions including net negative emissions in 2100, DAC will increase the roles of CCU by providing recovered CO2 from DAC, and also expand the opportunity for the use of recovered CO2 from fossil fuel combustion for synthetic fuels, because the related emissions are offset by larger negative emissions from the combination of DAC and CO2 storage (DACCS)."

Video: Climate Chat Club: The Godfather of Carbon Capture: Klaus Lackner (Interview)

"Dr. Klaus Lackner was one of the first scientists to explore how to remove excess CO2 from the atmosphere. In this wide-ranging masterclass interview, Klaus and host Dan Miller discuss the feasibility, scalability, safety, and cost of large-scale Direct Air Capture (DAC) and sequestration of atmospheric CO2. Klaus Lackner is the director of Center for Negative Carbon Emissions and a professor in the School of Sustainable Engineering and the Built Environment of the Ira A. Fulton Schools of Engineering at Arizona State University."

Project: Climeworks begins operations of Orca, the world’s largest direct air capture and CO₂ storage plant

"Climeworks launches Orca, the world’s largest direct air capture and storage plant that permanently removes CO₂ from the air. [...] Orca is the first-of-its-kind plant that translates the vision of industrial-scale direct air capture and storage into reality. This improved technology generation comes in an award-winning new design, which embodies the interconnection between nature and technology. For the technology generation which Orca represents, Climeworks has been able to intensify the process leading to increased CO₂ capture capacity per module. This optimized process means that more carbon dioxide can be captured and stored than ever before."

Blog: The Future of Carbon Capture: A View of the Current Players

"As per the 2021 IPCC report, it is clear that it is no longer sufficient to simply reduce carbon emissions. In order to tackle climate change, we need to rapidly remove carbon dioxide and other greenhouse gases from the atmosphere. While this seems daunting, hundreds of companies have worked towards various carbon capture and sequestration methods over the last few decades. We have compiled a list of some of these companies with a variety of carbon sequestration technologies."
