UK demonstrations confirm cool planet technologies carbon capture success
By Abbas Nazil
Cool Planet Technologies (CPT) has successfully showcased the effectiveness of its membrane-based carbon capture system during live demonstrations at its pilot plant in Grimsby, United Kingdom.
Industry visitors from the cement, lime, and steel sectors witnessed real-time carbon dioxide measurements before and after capture, continuously monitored using Vaisala MGP241 inline probes.
The live demonstrations provided clear verification that CPT’s system is achieving capture rates within one per cent of the predicted performance, affirming the reliability and efficiency of the technology.
Founded in 2019 to address the urgent need for scalable decarbonisation, CPT is commercialising a membrane technology developed in partnership with Helmholtz-Zentrum Hereon.
The system employs flat-sheet PolyActive™️ membranes that require no chemicals, deliver high efficiency, and have a long service life, all within compact modular units.
At the Grimsby pilot site, two modules operating in series are capable of capturing up to thirty-seven thousand tonnes of carbon dioxide per year.
The Vaisala probes continuously measure CO₂ concentrations at every stage of the process, ensuring the accuracy and verification of the system’s performance.
These demonstrations precede the commissioning of CPT’s 10,000-tonne-per-annum carbon capture plant at Höver, which is scheduled to begin operations in the second quarter of 2026.
CPT aims to achieve ninety-five per cent carbon dioxide recovery at the Höver plant, demonstrating the potential of its membrane technology to significantly reduce industrial emissions.
In collaboration with Holcim, CPT plans to scale up the technology to a full-site system capable of capturing approximately eight hundred thousand tonnes of CO₂ annually, targeting hard-to-abate industrial sectors.
The company emphasises that verified performance and transparency will be critical in gaining trust and encouraging widespread adoption of decarbonisation technologies.
This demonstration represents a milestone in industrial carbon capture, providing real-world evidence of membrane-based solutions as a viable and efficient method to mitigate greenhouse gas emissions.
CPT’s progress underscores the growing importance of scalable and reliable carbon capture technologies in meeting global climate goals while maintaining industrial productivity and sustainability.
The Grimsby pilot plant serves as a model for future deployments, validating membrane-based carbon capture as a key tool in the transition to low-carbon industrial processes.
