AI + CO₂ Capture at Coal Power Plants: Smarter Carbon Removal with Lower Costs - India Renewable Energy Consulting – Solar, Biomass, Wind, Cleantech
Select Page

Coal power remains a major source of global emissions, but Artificial Intelligence is making carbon capture more efficient, more reliable, and less expensive to operate. From real-time process control to predictive maintenance, AI is helping retrofit and future-ready plants cut millions of tonnes of CO₂ without crippling energy output.


🎯 How AI Can Make This Product or Solution Much Better

🔄 Dynamic Optimization of Capture Systems

AI adjusts solvent flow, regeneration temperature, and absorber pressure in real time, improving capture efficiency while cutting the plant’s parasitic load by up to 15%.


📊 Integration with Plant Load Changes

Coal plant output often shifts to meet grid demand. AI predicts changes in flue gas flow, CO₂ concentration, and temperature, adjusting capture parameters without performance loss.


🛠 Predictive Maintenance for CCS Units

Machine learning detects early signs of membrane wear, sorbent degradation, and heat exchanger fouling, reducing downtime and extending equipment life.
