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."

Yale Environment 360: The Dream of Carbon Air Capture Edges Toward Reality

"Next month, an industrial facility in Iceland will join a growing number of projects to remove CO2 from the air and put it underground. But major hurdles, including high costs, remain before this technology can be widely deployed and play a key role in tackling climate change."

Mackler, Sasha; et al. (2021): A policy agenda for gigaton-scale carbon management

Mackler, Sasha; Fishman, Xan; Broberg, Danny (2021): A policy agenda for gigaton-scale carbon management. In The Electricity Journal 34 (7), p. 106999. DOI: 10.1016/j.tej.2021.106999.

"the scale of the climate challenge is monumental. Today’s global economy still relies on fossil fuels for 84 % of its energy needs; these fuels are extracted, transported, processed, and consumed through large, intricate, and often interconnected systems that developed over more than a century and reflect trillions of dollars of invested capital. In 2019, the United States accounted for 6 billion of the 40 billion tons of greenhouse gases emitted globally. In the span of a few decades, we must transition to an economy with net-zero emissions. The scale of this challenge—technologically, financially, logistically, and politically—is difficult to overstate. And success will not be possible unless critical clean energy and climate mitigation technologies, several of which are still in the nascent stages of commercialization and deployment, are scaled by several orders of magnitude within the next two decades. Technologies for managing carbon emissions, including technologies that can capture carbon dioxide (CO2) from large point sources or remove CO2 from the atmosphere, are among these high priority solutions, and must be scaled to the gigaton level by 2050."
