Abstract
To address the high carbon emissions from fossil-fuel combustion and the intermittency challenge of renewable energy,this work focuses on the energy storage system that couples renewable power-driven water electrolysis to produce hydrogen with Haber-Bosch ammonia synthesis.It establishes a full-process model of kiloton-scale hydrogen-production-ammonia synthesis and conducts a systematic assessment of its energy storage efficiency,carbon emissions,and techno-economic performance.The results show that the energy storage efficiency of the full-process system is 44.3％when the PEM electrolyzer is used for hydrogen production.The comprehensive energy consumption decreases to 41.3 GJ/t.Under the ben-chmark conditions,the energy storage efficiency is 39.9％and the comprehensive energy consumption intensity is 46.6 GJ/t.The carbon emission intensity drops to 0.19 t/t under the wind power supplying conditions,reducing emissions by approximately 95％compared to traditional coal-based ammonia production.The total investment of the kiloton-scale project is 68.01 million yuan with the electrolyzer accounting for 42.7％,the annual operating cost is 11 million yuan with electricity costs accounting for 62％.The levelized cost of ammonia production(LCOA)is 5 102 yuan/t,and the net present value(NPV)is-45.83 million yuan.Sensitivity analysis indicates that NPV can turn from negative to positive when the annual production scale expands to 35 000 t,and LCOA can decrease by approximately 435 yuan/t for every 0.03 yuan/(kW·h)reduction in electricity price.The water electrolysis-coupled Haber-Bosch ammonia synthesis system exhibits excellent thermodynamic performance.Its synthesis loop achieves self-sustaining thermal operation through reactor waste heat recovery,eliminating the need of external heat utilities.At present,kiloton-scale demonstrations do not yet possess standalone commercial viability;the market competitiveness of green ammonia hinges on the synergistic support of economies of scale and declining renewable electricity costs.关键词
