CO2 scrubbing will require power, the generation of which will contribute to global emissions. Can this problem be solved ?



The subject of separation of gases from air is well documented. From an engineering perspective, air contacting (pumping of air through the removal apparatus, usually involving a membrane) is a major problem not least because the concentration of methane is relatively low, even though it is a more potent anthropogenic greenhouse gas than CO2. To pump high volumes of air and compress high volumes of methane would require a substantial magnitude of generated power thus contributing to even greater emissions.

Introducing a step change in generation efficiency would allow sufficient power to be made available.

Category of the action


What actions do you propose?

Who will take these actions?

Where will these actions be taken?

What are other key benefits?

Is an extension to a hydrogen economy in that a technology would be delivered which has applications in many current methane intensive operations.

What are the proposal’s costs?

High but due to the spread of costs, manageable.
