Cold Membrane CO2 Capture process

Cold membrane solution for carbon dioxide separation applications

July 2019
Gallery Cold Membrane CO2 Capture process 1
Gallery Cold Membrane CO2 Capture process 1


The technology consists of a hybrid membrane-liquefaction process to capture CO2 from stack gas of a power plant or industrial source, enabling electricity production by fossil fuel without emissions.

The cold membrane solution uses the Air Liquide hollow fiber membrane to separate carbon dioxide from flue gas (stack gas) of an industrial process such as power plant or hydrogen plant. The advantage of the cold membrane solution is improved membrane performance with increased product purity resulting in a lower number of membranes and low costs. It will also address carbon capture and utilization problem by: (1) Greenhouse gas emission reduction by capturing carbon dioxide from the flue gas, (2) Enabling greenhouse gas use for further application such as enhanced oil recovery (EOR) or concrete curing or for industrial applications.

Maturity stage Prototype testing in the real world
Looking For Partners, visibility

The environmental benefits

  • Separates CO2 from a flue gas source with low specific energy.
  • Simultaneously mitigates CO2 emissions and NOx, SOx, and Hg (mercury) from coal and natural gas combustion sources

The Financial benefits

  • A carbon capture cost of $40-45 per ton of CO2 compared to $56 per ton for amine process from a commercial coal power plante.
