Post-combustion capture With post-combustion capture, CO2 from a smokestack or flue gas is sent through a CO2 absorber containing chemicals called amines that absorb and attach themselves to the CO2. Gasifier Slag Coal Oxygen Sulphur removal Shift conversion H2 rich fuel gas N2 O2 H2O to atmosphere Gas turbine Air CO2 capture CO2 to storage Steam generator Steam turbine 4/24 > Illustative process of pre-combustion capture Source: Heidelberg Materials > enbridge.com/CCS Flue gas containing about 3 – 22% CO2 is diverted from the flue gas stack to the CO2 capture system. 9 Flue gas pre-treatment CO2 absorber CO2 stripper Treated flue gas (primarily contains: nitrogen, water vapor, trace elements with less than 2% CO2) Flue gas Pre-treated flue gas Lean amine Lean amine Rich amine Heat exchanger Rich amine Flue gas Pure CO2 (contains water) Heat (externally sourced) Compressed CO2 Stored Compressor dehydration unit Post-combustion capture: The path of CO2 through the amine-based capture process An advantage of pre-combustion capture is it can achieve high capture rates using less energy.

These terms are widely used in the industry, and we decided to adapt them for the main categories in our overview of carbon capture technologies in CaptureMap. However when we looked into the details we started running into issues linked to different definitions and criteria for categorising capture projects. Our take on it is that those capture technology categories were mostly defined at a time where power plants were the main targets for carbon capture, and therefore combustion was the main process to be considered. Next on our overview of carbon capture technologies we will talk about oxy-fuel, since it is, in our view, the category most related to post-combustion. > Pre-combustion carbon capture converts fuel into a mixture of hydrogen, CO2 and other gases, through gasification or reforming processes. As mentioned earlier, most of the capacity for carbon capture projects already in operations is concentrated within inherent process capture and pre-combustion. This indicates that the actual capture technology is likely to be inherent process capture or pre-combustion, increasing further the share of capture projects capacities within those categories.

Our Direct Air Capture (DAC) technology does this by pulling in atmospheric air, then through a series of chemical reactions, extracts the carbon dioxide (CO2) from it while returning the rest of the air to the environment. ### Our Direct Air Capture technology has been designed to continuously capture CO2 from atmospheric air and deliver it as a gas for use or storage, bringing together four major pieces of equipment that each have industrial precedent. CE’s Direct Air Capture process, showing the major unit operations - air contactor, pellet reactor, slaker, and calciner - which collectively capture, purify, and compress atmospheric CO<sub>2</sub>.

The top 10 carbon capture technologies explained. # The Top 10 Carbon Capture Technologies Explained. Carbon capture technologies offer remarkable solutions to this problem. Know what the top 10 carbon capture technologies and their potential applications are! ## What are the top 10 carbon capture technologies? Carbon capture technology has been introduced as a solution to reduce carbon emissions in the atmosphere. DAC technology uses air filters to capture carbon dioxide from the atmosphere directly. This technology is used to capture carbon emissions from power plants before they are released into the atmosphere. Although this technology has limitations, it is currently the most widely used carbon capture technology, and the scale of its application can be significant in reducing carbon emissions. While still in its infancy, carbon capture and conversion technology is a sustainable approach to reducing the carbon footprint while producing valuable products. ## Each carbon capture technology has different advantages, and they complement each other. Summarizing, carbon capture technologies are crucial to reducing the carbon footprint in various sectors.

# 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.
