Holcim, Cool Planet developing CO2 capture plant in Germany


Sustainable technology company Cool Planet Technologies Limited (CPT) will push for decarbonisation efforts using membrane gas separation technology along with Holcim Deutschland GmbH (Holcim).

In conjunction with partner Helmholtz-Zentrum hereon GmbH (Hereon), the companies plan to build a carbon dioxide (CO2) capture plant at Holcim’s Hover cement works near Hannover.

The plant will harness Hereon’s PolyActive membrane technology, which uses a selective barrier material that filters some gases but allows through CO2. The low-cost solution is passive and requires less energy, in addition to being easily scalable, providing a suitable option for retrofitting or ‘end of pipe’ projects.
