%X 氢能产业是战略性新兴产业和未来产业的重点发展方向，采用可再生能源制备的绿氢是实现用能终端绿色低碳转型的重要载体，但目前为止，绿电制氢项目普遍面临收益低下的问题，因此，文章通过选取新能源场景建立计算模型，运用氢的平准化成本(LCOH)法对新能源发电制氢的经济性——即内部收益率进行了评估，并分析了制氢成本的敏感因素，对绿氢在新型电力系统的发展给出了针对性建议，分析结果显示影响制氢成本的主要因素为：制氢效率，电价，投资成本等。为提高制氢效率并展开持续的稳态制氢就必须要克服绿电的波动特性，文章建议制氢工艺系统的优化发展以集群式柔性调节技术作为主要的技术突破方向，即采取配置储能、降低并、离网调频、采用新一代IGBT技术的制氢设备、为系统设置智能化能量算法等，这些协调方式都可以有效地缓解能量波动对制氢化学反应带来的冲击，此外，文章分析结果显示，把控中间产品“电价”将对绿氢成本影响深远，低成本的电力是实现绿氢与绿电联合这一预期的关键，这对电力系统的长期规划和运行提出了要求，也强调了电网的承接和政策支持的必要性。
The hydrogen energy industry is a strategic emerging industry and a key development direction for future industries. Green hydrogen produced from renewable energy is an important carrier for achieving green and low-carbon transformation of energy terminals. However, green electricity hydrogen production projects generally face the problem of low returns. Therefore, this article selects new energy scenarios to establish a calculation model, uses the Levelized Cost of Hydrogen (LCOH) method to evaluate the economic feasibility—specifically the internal rate of return—of new energy power hydrogen production, and analyzes the sensitive factors of hydrogen production costs. Targeted suggestions are given for the development of green hydrogen in new power systems. The analysis results show that the main factors affecting hydrogen production costs are: hydrogen production efficiency, electricity prices, investment costs, etc. In order to improve hydrogen production efficiency and carry out continuous steady-state hydrogen production, it is necessary to overcome the fluctuation characteristics of green electricity. This article suggests that the optimization and development of hydrogen production process systems should focus on cluster flexible regulation technology as the main technological breakthrough direction, which includes configuring energy storage, reducing grid-connected and off-grid frequency regulation, adopting new generation IGBT technology for hydrogen production equipment, and setting intelligent energy algorithms for the system. These coordination methods can effectively alleviate the impact of energy fluctuations on hydrogen production chemical reactions. In addition, the analysis results of this article show that controlling the “electricity price” of intermediate products will have a profound impact on the cost of green hydrogen. Low-cost electricity is the key to achieving the expected combination
