Advanced, efficient membrane capture

Cool Planet Technologies has developed an advanced membrane-based process, for the large-scale capture of carbon dioxide from industrial flue gas emissions. The sophisticated PolyActive™ membrane used in Cool Planet Technologies process has been developed by Helmholtz-Zentrum Hereon, part of Germany’s largest research organisation. Cool Planet Technologies and Hereon are collaborating in the development, up-scaling and commercialisation of the technology.

The process can be used across a wide range of industries and applications and can be flexibly configured from capturing a few thousand to multi-millions of tonnes of CO2 per annum (tpa). This energy efficient solution can capture up to 99% of the CO2 from a flue gas, exporting it as either a gas or liquid with a purity of up to 99.9%. The compact, modular process has a small footprint making it an ideal for both retrofit or new-build solutions. Operationally, the process is extremely flexible with rapid start-up, shut-down response and excellent turn up/down capability. The capture plants can also be easily expanded and upgraded as required. The capture process is optimised for cement, blast furnaces, smelters, paper and pulp, waste to energy and refineries.

The technology has been previously piloted in two coal-fired power station projects under the German government METPOR II and MemKoR programmes. Cool Planet Technologies has also completed a highly successful third pilot with Holcim to decarbonise their Höver cement plant near Hanover in Germany in May 2022 as part the ongoing project there. A demonstration plant capable of capturing up to 16,000 tpa will commence operations at Höver in 2025 which will be followed by 200,000 tpa and 1,000,000 tpa plants in 2026 and 2028 respectively.
