This paper presents the deployment and operational evaluation of a 20 tonnes per day (TPD) Carbon Capture and Utilisation (CCU) facility at NTPC Vindhyachal Super Thermal Power Station, India. The study evaluates industrial integration of post-combustion CO2 capture with catalytic methanol synthesis in a coal-fired environment, focusing on operational performance, process integration, and the feasibility of end-to-end CO2 utilisation under commercial operating conditions. CO2 was captured from flue gas from a 500 MW coal-fired power unit using Carbon Clean's CaptureX™ semi-modular technology along with APBS-CDRMax® solvent. The skid-mounted configuration addressed footprint constraints associated with brownfield retrofit applications. The system was designed for 20 TPD CO2 capture at 80% capture efficiency and CO2 purity of <99.4 mol% Dry, with steam consumption of 1.54 t/tCO2 and solvent consumption of <0.35 kg/tCO2. Captured CO2 was conditioned and combined with green hydrogen for catalytic hydrogenation to methanol, targeting 10 TPD methanol production under integrated operation. The facility has accumulated many operating hours under coal-fired flue gas conditions, representing a long-duration dataset for an integrated post-combustion CCU system. Capture performance met or exceeded design targets, achieving 86.9% CO2 capture efficiency and 99.95% CO2 product purity while maintaining steam and solvent consumption within design expectations. The system demonstrated stable integration between capture and downstream utilisation units, including catalytic conversion of captured CO2 to methanol under industrial operating conditions. These results indicate that semi-modular post-combustion CCU systems can maintain stable performance under continuous coal-fired operation and support integrated deployment pathways for retrofit applications. Existing literature on coal-fired carbon capture is largely limited to laboratory studies, process simulations, or stand-alone capture systems. This work presents operational evidence from the first reported industrial deployment integrating post-combustion CO2 capture with downstream CO2-to-methanol conversion at an operating Indian coal-fired power station.
