Abstract

Abstract:

Co-firing green ammonia with coal-based fuels is a feasible carbon reduction pathway for coal-fired power plants.Analyzing carbon reduction across the entire chain not only facilitates the development of the green hydrogen and green ammonia industries and effectively promotes their efficient utilization，but also supports the advancement of ammonia-coal co-firing technology.In a scenario where green ammonia was produced using renewable energy-powered green electricity and co-fired of ammonia with coal in coal-fired power plants， the total CO₂ reduction throughout the chain was calculated.The results showed that using 445 GW·h of green electricity to produce green ammonia and co-firing it in coal-fired units achieved a total CO₂ reduction of 100.7 thousand tons/year.The CO₂ reduction per unit of green electricity was approximately 226.29 g/（kW·h），and annual carbon reduction cost savings were estimated at 9.5 665×10⁶ yuan.

Key words: renewable energy, green hydrogen, synthetic ammonia, green ammonia, ammonia-coal co-firing power generation, carbon dioxide emission reduction
