Direct Air Capture
Technical Mesh for Clean Air
Less carbon dioxide for cleaner air: Humanity is facing the immense task of limiting global warming to 1.5°C above pre-industrial levels by 2100, thereby reducing the greenhouse effect. This goal will primarily be achieved by significantly reducing carbon emissions worldwide.
In addition, efforts are being made to capture and store climate-damaging carbon dioxide from the air. This process, known as Direct Air Capture (DAC), involves either permanently storing the CO2 (Carbon Capture & Storage) or reusing it (Carbon Capture Utilization) in applications such as plant nurseries, carbonated beverages, and synthetic fuels.
CO2 is removed from the air using chemical sorbent media, such as aqueous alkaline solvents or adsorbents. These non-soluble materials absorb and retain liquids, allowing CO2 to be extracted using thermal energy. The sorbent media can then be reused. GKD supports DAC with advanced filtration solutions.
The Solution: Direct Air Capture (DAC) with Metal Mesh from GKD
In the course of research and development of the DAC process, various methods have proven their worth:
- Liquid solvent: Here, an aqueous potassium hydroxide solution reacts with the CO2 in an air contactor and forms water and potassium carbonate.
- Solid sorbent: The air is blown through an air contactor with a solid adsorbent that adsorbs CO2. To release the CO2, the adsorbent is then exposed to heat and/or a vacuum before being cooled and reused.
GKD provides high-performance metal mesh with low pressure loss for adsorption. These are available in cylindrical or rectangular shapes and ensure that the granulate remains reliably in the correct position. GKD thus offers an innovative solution for the challenges of tomorrow.
