How does an air-capture device compare to a tree?
Just as a tree stands in the open with air blowing over its leaves, an air-capture unit stands in the open and captures CO2 on its collector surfaces, or “leaves.” Tree leaves need sunlight to convert captured CO2 to starch. By contrast the ACCESS air-capture system simply collects CO2 on a proprietary sorbent and later releases it again, while cleaning and pressurizing the gas to meet the specifications of CO2 storage or end-use. The GRT air-capture system is about one thousand times more efficient than a tree of equal size, in large part because the GRT collector does not need to capture sunlight. Its “leaves” can be packed tightly without concern over shading, and the ACCESS system will function 24 hours a day.
