Step by step

How the hybrid process works

  1. 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.

  2. 02

    CO₂ Desorption

    Green H₂ drives desorption in a counter-current sweep, releasing the CO₂ and cutting pressure-energy demand significantly.

  3. 03

    Methanol Synthesis

    CO₂ and H₂ react over a catalyst to produce a MeOH-water mixture — the core conversion step.

  4. 04

    Distillation

    Methanol is separated from water, producing IMPCA AA-spec green methanol ready for use.

  5. 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.
