Co-firing with a 20% share of ammonia could reduce the 6 GtCO2/yr annual emissions of these coal plants by 1.2 GtCO2, provided that the ammonia was produced from low-carbon hydrogen. Reaching a 20% blending share would result in an annual ammonia demand of 670 Mt, more than three times today's global ammonia production.
The utilization of ammonia as a partial substitute for coal has garnered considerable attention as a technology for direct reduction of CO 2 emissions in power plants. This study has established the model of ammonia co-firing in coal-fired power plants (CFPP), encompassing the whole industrial chain from production to …
