Direct Air Capture is the practice of separating CO2 from ambient air. This occurs typically through chemical or physical separation, allowing the greenhouse gas to be captured and purified for use as an industrial gas or safely sequestered in underground geological formations, thereby removing the CO2 permanently from the atmosphere.
In 1999, Dr Klaus Lackner was the first scientist globally to suggest CO2 could be captured from the air to tackle global warming. A significant feature of direct air capture is that it treats the root cause of climate change: emissions left in the air from fossil fuel use. This includes emissions from both point sources (for example, Chemical plants, refineries, power plants and other industrial sites producing CO2 emissions) and mobile/hard-to-abate sources (including aircraft and other modes of transport, construction and agri vehicles and equipment).
Direct Air Capture is an essential tool for mitigating the effects of co2 emissions in the atmosphere.
Traditional approaches to direct air capture technologies have been constrained by high cost of capture of CO2, reflecting energy intensive processes, and challenges in scaling.
Using proprietary passive direct air capture (PDACTM) technology, Carbon Collect has overcome key economic challenges of Direct Air Capture. The company’s MechanicaltreeTM uses ambient wind to deliver CO2. This passive approach removes the need for forced convection (fans and blowers) typical to other DAC systems.
The modular design of Carbon Collect’s MechanicaltreeTM combined with passive capture and a new geometry for DAC enables easy scaling. The company’s Passive Direct Air Capture MechanicaltreeTM offers significant advances on scalability and energy costs.
