Carbon removal technology: our service to remove CO₂

https://climeworks.com/carbon-removal-technology

## Helping you remove CO₂ from the air. With over a decade of expertise, we design, build, and operate our own Direct Air Capture and Storage facilities, ensuring top-quality, efficient carbon removal. To reach this target, we must first reduce emissions, and then actively remove CO₂ from the atmosphere. Carbon removal solutions can neutralize these residual emissions, helping to achieve net-zero goals. Technologies like direct air capture can directly remove this historic CO₂ from the air, effectively reversing the effects of past emissions. Direct air capture (DAC) is a technology that captures CO₂ directly from the air. Unlike traditional carbon capture methods focused on industrial emissions, DAC offers a versatile solution for emission reductions and removal by capturing CO₂ from the air. 1. **Atmospheric capture:** Our advanced DAC facilities use specialized filters to extract CO₂ from the ambient air. Direct air capture is one of today's most promising carbon removal technologies. Direct air capture and storage: how the full process from CO₂ capture to storage works in Iceland.

6 Ways to Remove Carbon Pollution from the Atmosphere

https://www.wri.org/insights/6-ways-remove-carbon-pollution-sky

Carbon removal strategies include familiar approaches like growing trees as well as more novel technologies like direct air capture, which scrubs CO2 from the air after which it can be sequestered underground. **The latest** **climate model scenarios** **show that in addition to substantial and rapid emissions reductions, large-scale carbon removal will be needed to keep temperature rise to 1.5 degrees C.** The amount of carbon removal ultimately needed will depend on how quickly we reduce emissions in the near term as well as the magnitude and duration of any increase above 1.5 degrees C, known as overshoot. Some management approaches that can increase carbon removal by trees and forests include:. Cost estimates for DAC with sequestration vary: voluntary purchases of carbon removal credits from direct air capture range from $100 to more than $2,000 per metric ton of CO2 depending on the technology, energy source, use of policy incentives, and other factors.

DOE Explains...Direct Air Capture - Department of Energy

https://www.energy.gov/science/doe-explainsdirect-air-capture

# DOE Explains...Direct Air Capture. The Department of Energy’s Regional Direct Air Capture Hubs program will develop four domestic direct air capture hubs to demonstrate a direct air capture technology or suite of technologies at a commercial scale. The Department of Energy’s Regional Direct Air Capture Hubs program will develop four domestic direct air capture hubs to demonstrate a direct air capture technology or suite of technologies at a commercial scale. **Direct air capture** technology is a form of carbon dioxide (CO2) removal that takes CO2 from ambient, or still, air. ## DOE Office of Science: Contributions to Direct Air Capture. DOE supports direct air capture research, development, and demonstration through the Offices of Fossil Energy and Carbon Management and Clean Energy Demonstrations and the Advanced Research Projects Agency–Energy. DOE also supports research on direct air capture through the Office of Science Basic Energy Sciences (BES) and Biological and Environmental Research (BER) programs.
