Simple. Safe. Stable.
Commodity inorganic solvents — no amines, no degradation, no specialty sorbents.
Waste Heat Into Valued Carbon
Tough Tech · Carbon Capture
CO2ncentrate converts 35–95°C waste heat into purified CO2 streams — enabling direct air capture and utilization at industrial sites, data centers, and beyond.

The problem
Two-thirds of energy is wasted.
67% of primary energy is rejected as low-grade heat — from electricity production, HVAC, transportation, and more. Today's amine and solid-sorbent capture systems can't use it economically, so it vents while CO2 capture stays expensive.
Global primary energy
That waste heat is the world's largest untapped energy resource.
The breakthrough
Carbonate chemistry, powered by waste heat.
Cold carbonate solution absorbs CO2; gentle heat drives it back out — no combustion, no high-grade energy required. Modular stages purify CO2 from any feed up to 1 bar on a temperature differential as small as 10°C. No complex chemistry. No high-energy regeneration.
❄ Cold side
Absorb
≈ 25°C
Carbonate solution captures CO2 from the feed stream.
🔥 Hot side
Release
≈ 65°C
Low-grade heat drives concentrated CO2 back out of solution.
What it unlocks
A capture platform with no fragile parts.
Ultra-low grade heat
Operates at 35–95°C with a 10°C minimum differential.
One process, every source
Direct air capture, point source capture, and outgassing up to 1 bar CO2.
How it works
Four stages. One closed loop.
-
01
Absorb
Cool carbonate solution pulls CO2 from any feed stream.
-
02
Circulate
Saturated brine circulates between vessels. Integrated exchangers conserve thermal energy between stages.
-
03
Heat
Low-grade heat drives CO2 back out of solution.
-
04
Repeat
Repeated absorb–release cycles across multiple stages concentrate CO2 to spec.
