Carbon Capture Plants, decoded.
Direct-air and point-source capture, by scale and cost.
CURATED INDEX◊ confidence: Medium
// the signal · what the data says
Carbon capture splits between cheap point-source (industrial flue gas, $50-100/t) and expensive direct-air capture (DAC, $400-700/t). Occidental's Stratos (500kt/yr) is the largest DAC plant; costs must fall roughly 5x for DAC to matter at climate scale.
