Direct Air Capture
Running the smokestack in reverse — pulling CO2 straight out of the ambient air.

The Problem
Cutting emissions alone can't hit our targets — legacy carbon lingers for centuries, even after we reach net-zero.

The Mechanism
How Direct Air Capture Works
A closed loop: capture, release, regenerate, repeat.

The Brutal Economics
Cost today$250+
per ton captured
Capturing a ton of CO2 costs between $250 and $600 today — dominated almost entirely by energy.
What has to change
-
$600
Upper bound today The high end of current per-ton capture costs.
-
$100
Target to matter The cost must fall below $100/ton to be climate-relevant.
-
Power
Cheap clean energy Moving air and regenerating sorbent is the whole game.

Where the Carbon Goes
Sequestration vs. Utilization
Utilization
Reuse the carbon
- Turns CO2 into synthetic fuels
- Feeds concrete and chemical feedstock
- Often re-releases the carbon later
- Does not count as true removal
VS
Sequestration
Store it forever
- Injects CO2 into basalt or saline aquifers
- Mineralizes into solid rock over years
- Permanent — locked away for good
- The only path that counts as removal

What Has to Go Right
Three Levers
None optional. All must break the right way.
01
Cheap Energy
Plummeting renewable prices make moving air and regenerating sorbent affordable.
Renewables
02
Policy Support
Markets and mandates that actually pay for verified carbon removal.
Incentives
03
Better Engineering
Sorbent and process innovation that drives cost down toward $100/ton.
