The Atmos CCT-9 is a 200-meter-tall industrial structure designed to extract carbon dioxide from the atmosphere at a rate of 50,000 metric tons per year. The tower draws ambient air through massive intake vents at its base, passes it through a series of chemical scrubbing stages that strip CO2 from the air stream, and exhausts cleaned air from vents along its upper sections. The captured carbon is compressed into solid blocks and transported to deep geological storage facilities or sold to industrial customers who use carbon as a manufacturing feedstock.

The CCT-9 represents the ninth generation of Crucible's carbon capture technology, incorporating improvements in scrubbing chemistry, air handling efficiency, and heat recovery that have reduced the energy cost per ton of captured carbon by 60% compared to the first-generation units deployed in the 2140s. The tower requires approximately 15 megawatts of continuous power — typically supplied by a dedicated Ouroboros Energy trunk line — and generates enough waste heat to warm a surrounding district of 5,000 residential units through a distributed heat recovery system.

Crucible operates approximately 2,400 Atmos towers worldwide, concentrated in regions with the highest legacy carbon concentrations. The towers are a common feature of GLMZ's industrial skyline, their constant air intake creating localized wind patterns that residents have learned to account for in their daily movement. The atmospheric CO2 concentration in 2200 has been reduced from its peak of 680 ppm in 2095 to approximately 340 ppm — a level not seen since the early 21st century — largely through the cumulative effort of carbon capture infrastructure. Crucible receives carbon credits for each ton captured, creating a revenue stream that makes the towers profitable even without direct product sales.
