Direct Air Capture
Machinery that pulls carbon dioxide directly out of ambient air for permanent storage or industrial use.
Why does it matter?
Some emissions — aviation, cement, agriculture — are very hard to eliminate. Removal is the only route to net zero for that remainder, but only if cost per tonne falls dramatically.
How does it work?
Air is drawn across a chemical sorbent that binds CO₂. Heat or a pressure swing releases a concentrated stream, which is then compressed and injected into geological storage.
Where is it today?
Operating plants remove thousands of tonnes per year at a cost far above most carbon prices. Energy supply is the dominant cost driver.
