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: Flexible Carbon Capture and Storage Modeling (Kleinman Center for Energy Policy)

"In collaboration with Colorado State University and with funding from ARPA-E, the team continues to work on computer modeling for natural gas power plants with carbon capture systems (NGCC) in a future with increased renewables on the grid. This system includes a solution that stores both hot and cold energy when the NGCC plant is not contributing to the grid (i.e. during peak solar hours): the stored heat circles back to the carbon capture system and the stored cold energy feeds the natural gas plant, improving efficiency while reducing emissions."

Project: Indirect Carbonation of Alkaline Waste (Kleinman Center for Energy Policy)

"Connected to mine remediation, lab researchers are exploring chemistry that could support the process of reverse mining, or backfilling mines with mine waste infused with CO2. This process would clean the atmosphere while offering mine owners a more valuable product—a qualified carbon offset. An additional health benefit occurs with mine waste composed of asbestos. Reacting CO2 with asbestos alters it from a fibrous mineral (that can be inhaled) into a more benign form."

Project: State Mapping Study (Kleinman Center for Energy Policy)

"In partnership with the Nature Conservancy, the lab is working on a custom plan to help the state of Nevada achieve its Net-Zero by 2050 goal—through decarbonization and carbon removal. The plan considers the state’s assets and liabilities—for example, Nevada has a lot of opportunities for geothermal and solar but doesn’t have many forests (for carbon sinks). The goal is to create a sliding scale of options—from more decarbonization and less carbon removal to the flip side. From there, the team hopes to apply this model to other states."

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."

Project: Carbfix Atlas

"As a sign of ever-increasing interest in CO2 mineral storage, Carbfix has compiled a mapping tool that shows the feasibility of applying the Carbfix technology for industries and nations to assess as a part of their climate strategy. The global storage potential is greater than the emissions of the burning of all fossil fuels on Earth.It is estimated that Europe could theoretically store at least 4,000 billion tons of CO2 in rocks while the United States could store at least 7,500 billion tons."

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."
