Advanced Membrane Technology

Cutting the Cost of Carbon Capture

Cool Planet Technologies’ class leading membrane-based carbon capture process delivers high performance industrial capture at significantly reduced costs compared to existing technologies.


PolyActive™ Capture

Advanced, Efficient Membrane Technology

Cool Plant Technologies has developed an advanced membrane-based process, PolyActive™ Capture, for the large-scale capture of carbon dioxide from industrial flue gas emissions.  The PolyActive™ membrane technology has been developed by the Helmholtz-Zentrum Hereon, part of the Helmholtz Institute, a world class renowned research institute based in Germany. 

In comparison with the currently preferred technologies PolyActive™ Capture is compact, easier to use, consumes significantly less energy and can be installed and operated at a lower cost, making it a low risk, cost effective technology.  It can be retrofitted to existing plants or installed as part of a new-build.

The PolyActive™ technology has been successfully pilot tested in two coal fired power stations under the German government METPOR II and MemKoR programmes.  In 2022 a pilot was undertaken on the Höver cement plant in Hanover with very promising results.  

We expect to have a full scale plant installed in the next 5 years and we are planning  a manufacturing facility to facilitate the rapid deployment of the technology to global industrial applications.


Cool Planet Technologies’ flagship project is with Holcim, the world largest cement company, at their Höver cement works, near Hannover. 

Cool Planet and its partner Helmholtz-Zentrum hereon GmbH (Hereon), have a Memorandum of Understanding with Holcim to build a COcapture plant based on the PolyActive™ Capture membrane technology. 

Cool Planet Technologies is adopting a phased approach for scaling membrane technology: 

Phase 1 

This Phase of Cool Planet Technologies’ Carbon Capture project was completed in May 2022 and generated useful data for further calibrating Phase 2a of the project.  The test unit delivered an excellent separation rate with high COpurities.  The unit also demonstrated its ability to start up and respond very quickly without any preliminary preparations.   

Holcim Press Release May 22

“After several weeks of running the test facility and completion of the preliminary test phase, the results are extremely positive. “We can observe a good separation rate and comparatively high purities. We are pleased with the very promising results of the first test phase,” says Holcim Plant Manager Stephan Hinrichs. “I am very proud that we are one of the first cement plants in the world to gain really practical experience with COcapture.”

Phase 2a will be a major scaling up of the PolyActive™ Capture technology capturing 6,000 tonnes per year (tpa) of CO2.  This Phase has been authorised and is scheduled to be in operation in mid-2023. 

Other Projects

Cool Planet Technologies is working with partners to develop further projects in the pulp and paper industry, and for blast furnaces and smelters.  The PolyActive™ Capture technology has the capability and flexibility to deliver high quality performance in these diverse and sometimes challenging operational environments.
