Cool Planet Technologies is adopting a phased approach for scaling membrane technology at the Höver plant:

This Phase of Cool Planet Technologies’ carbon capture project at Höver 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 CO₂ purities. The unit also demonstrated its ability to start up and respond very quickly without any preliminary preparations.

Currently under construction, Phase 2a is a major scaling up of the technology capturing approximately 10,000 tonnes per year (tpa) of CO₂. This Phase has received funding approval from the German Federal Ministry for Economic Affairs and Climate Action (“BMWK”) as part of the “Decarbonisation in Industry” funding programme. This plant will have an active test programme and operate for 12 months before being relocated to another site outside Germany for further capture operations.

Phase 2a is scheduled to commence operation in 2025.

Cool Planet Technologies plans to have a 200,000 tpa capture plant operational in 2028 followed by a 380,000 tpa plant and a 1,000,000 tpa capture plant both in 2030.
