Hi there

Making climate change a thing of the past —one atom at a time.


How Graphene Membranes are made


Graphene Synthesis

Our filters are made from a special material called Graphene. With a thickness of just 1 atom, it can lead to record breaking performances and push the boundary of what is possible to do with membrane science. The characteristics of this material has led to the Nobel Prize in Physics in 2010.


Pore Creation

After synthesizing graphene, we make tiny holes just about the size of the CO2 molecule. These holes work like a sieve and only let CO2 to go through which enable us to separate it from other molecules.


Module Integration

Finally, we roll these porous graphene membrane and integrate them into a mechanical module that will be later installed at the industrial site.

A non-trivial endeavour

Several tricky production steps are needed to synthesize graphene membranes and we are the only group in the world capable of doing so. In addition to the expertise developed over the years, we have patents that protects the different synthesis steps.

Cost and Energy efficient

Thanks to its record breaking performance, graphene membranes can dramatically reduce the cost and energy use. This leads to an economical viable solution for low concentration streams, like aluminum smelters.

No heat needed

Membranes does not use heat to operate and only require electrical energy. This broadens the field of the industries that can use carbon capture. I also doesn't use solvents which evaporates into the atmosphere and can cause environmental concerns.

Compact and easy to Install

Graphene membranes results in a very compact and modular installation. This makes carbon capture available where space is a scarce resource, such as offshore oil platforms.


Graphene, an inorganic material, can have a longer lifespan than polymeric membranes and is less prone to react with impurities. It can also be regenerated to regain its initial performance.


Our process is tailored to your industry

How the process works

We produce special filters and package them inside an installation at an industrial emitter's site. This installation would be connected to the flue gas and would remove its CO2 content. Instead of being released into the atmosphere, this CO2 will either be stored permanently or used to create derived products.

You are a company located anywhere in the world, and you're looking for a solution to capture your CO2? All you have to do is contact us, and we'll provide you with a solution tailored to your needs. We can also discuss a demonstrator project to test our membrane on a small-scale at your site to collect data and assess compatibility with your process.

Industries and their hard to abate emissions

Why Carbon Capture is Important

Industries like cement, iron and steel, and chemicals account for about 34 percent of global CO2 emissions. Emissions from these industries are notoriously difficult to abate because, in addition to emissions associated with energy use, a significant portion of industrial emissions come from the process itself.
