摘要
由于在储能和制氢方面具有显著的优势,氨制氢储能系统可以在未来"双碳"目标推进和能源系统建设中扮演重要角色.本工作模拟了氨分解管式填充床反应器在电加热情况下的工作特性,并将其纳入到考虑源荷两侧不确定性和风光火储的电力系统中.分析了在三种不同电力系统装机构成下,氨分解系统装机容量增加对电力系统的度电成本、度电碳排放、新能源发电占比、新能源利用率和氢气日产量等性能指标的影响.结果表明:氨分解系统可以有效提高新能源发电消纳水平,不同装机构成下配备最大氨分解系统容量可使得新能源利用率提高5.5%～62.4%,新能源发电占比提高14.2%～160.8%;由此带来的度电碳排放降低0.9%～22.8%,而度电成本提高7.6%～34.5%;氢气日产量分别达到3.9万吨、10.4万吨和17.1万吨.本文研究结果可为在电力系统中配置氨分解制氢储能系统以推动碳减排和氢能技术发展提供参考.
Abstract
Due to its remarkable advantages,the ammonia decomposition hydrogen production and energy storage system are crucial for advancing future dual carbon goals and energy system construction.Herein,the operating characteristics of an ammonia decomposition tubular filled-bed reactor under electrical heating are simulated and incorporated into a power system,considering uncertainties on both sides of the source load.The effects of increased capacity of the installed ammonia decomposition system on the performance indicators of the power system,such as electricity costs,carbon emissions per kWh,share of new energy generation,utilization rate of new energy,and daily hydrogen production,are analyzed under three different power system installation compositions.The results show that the ammonia decomposition system can effectively improve the consumption level of new energy generation.The maximum capacity of the ammonia decomposition system can increase the utilization rate of new energy by 5.5%—62.4%and the share of new energy generation by 14.2%—160.8%under the three compositions;the resulting carbon emissions from electricity generation are reduced by 0.9%—22.8%,and the cost of electricity generation is increased by 7.6%—34.5%.For the three compositions,the daily hydrogen production reaches 39,000,104,000,and 171,000 tons,respectively.The results of this study can provide a reference for configuring the ammonia decomposition hydrogen storage system in the power system to reduce carbon emission and promote hydrogen energy technology development.
