Green methanol production technology
Technology
ICODOS' patented e-methanol production technology enables lowest-cost and at-scale production of sustainable e-methanol.
THE ICODOS PROCESS
From CO₂ source to green methanol
FEEDSTOCK
Our patented hybrid process integrates point-source CO₂ capture and methanol synthesis in a single, dynamically operated plant.

How the hybrid process works
01
CO₂ Absorption
A MeOH-water solvent absorbs CO₂ from the point source. Physical absorption — no amines, no membranes, 50% more energy efficient than conventional methods.
02
CO₂ Desorption
Green H₂ drives desorption in a counter-current sweep, releasing the CO₂ and cutting pressure-energy demand significantly.
03
Methanol Synthesis
CO₂ and H₂ react over a catalyst to produce a MeOH-water mixture — the core conversion step.
04
Distillation
Methanol is separated from water, producing IMPCA AA-spec green methanol ready for use.
05
Green Methanol
The final product is certified RFNBO e-methanol — suitable for marine fuel, chemicals, and methanol-to-jet (SAF) applications.
FEEDSTOCK FLEXIBILITY
One capture process, multiple feedstocks
ICODOS separates CO₂ from any source gas, and the captured CO₂ always becomes e-methanol.
What leaves the top of the absorber — and its value — is what changes with the feed.
