Advancing the ROTA-CAP™ Intensified Carbon Capture System

The industrial sector is vital to thriving economies, demanding strong operational performance without sacrificing reliability or affordability. GTI Energy is leading a major international effort to advance carbon capture technology for cutting emissions from energy-intensive industries.

ROTA-CAP™ is GTI Energy’s modular, scalable, integrated industrial carbon capture system that uses a novel approach to reduce the size, capital cost and operating expenditure for CO2 capture systems. ROTA-CAP is suitable for power plant and industrial carbon capture applications, can achieve >95% capture for a wide range of flue gases, and can reduce CO2 capture costs by 30-50% compared to conventional process approaches. The technology accomplishes that by combining compact rotating packed bed (RPB) technology with advanced solvent technology, to intensify the carbon capture process.

With funding from the U.S. Department of Energy and Low Emission Technology Australia (LETA), GTI Energy and project team members U. S. Steel, Amrize (formerly Holcim US), and Enbridge will advance ROTA-CAP™ through testing at 10-tonne per day pilot scale at U. S. Steel’s Edgar Thomson facility in Braddock, Pennsylvania, USA. The project aims to assess the technology’s readiness for scale-up and enable wider deployment across the steel, cement, and other hard-to-abate industries.

ROTA-CAP™ has undergone extensive proof-of-concept and performance validation testing at the National Carbon Capture Center. Testing in real industrial environments will further advance the technology toward commercial readiness.
