The technology
Solid-sorbent direct air capture, measured molecule by molecule
A continuous, electrified capture cycle designed for durability of storage and defensibility of data. This is the full engineering picture — no black boxes.
Clean-energy powered · Facility 04, Pilbara
Process schematic
The capture cycle, end to end
01
Air intake
Ambient air drawn through contactor arrays at ~415 ppm CO₂.
02
Sorbent binding
Amine-functionalized sorbent chemically binds CO₂ at the surface.
03
Thermal release
Waste heat at 95°C regenerates sorbent, freeing concentrated CO₂.
04
Compression
Stream dried and compressed to 150 bar for pipeline transport.
05
Mineralization
Injected into basalt; carbonates within 24 months. Permanent.

MRV methodology
Every ton is measured, reported, and verified — not modeled
CO₂ flow is metered continuously at capture and injection. Third-party auditors reconcile the two, subtract lifecycle emissions, and issue credits only against net durable removal.
✓
Continuous flow metering at both capture and injection points
✓
Independent lifecycle assessment across the full facility boundary
✓
Seismic and geochemical monitoring of injection reservoirs
