氢电耦合系统应用场景分析研究

Application Scenarios of Hydrogen-electric Coupling System

火力发电机组为目前中国能源结构中装机容量最大的发电机组,它造成的能源消耗过大。而氢能具有低碳清洁、储存时间长的优点。在此背景下,提出让制氢加氢系统参与火电机组辅助调峰服务,消纳可再生能源发电,提高火电机组负荷,促进电网系统的安全稳定。结合具体项目分析得出,火电耦合电解水制氢加氢一体站在空间布置、工艺流程和市场前景方面具有一定的可行性,为电厂灵活性改造转型及区域氢能发展提供了参考。

Thermal power generation units are of the largest installed capacity in China's energy structure,it can cause excessive energy consumption.But the hydrogen energy has the advantages of low carbon,clean and long storage time.In this context,it is proposed that the hydrogen production and hydrogenation system should participate in the auxiliary peak regulating service of thermal power units,absorb renewable energy generation,improve thermal power unit load,and promote the safety and stability of the power grid system.Based on the analysis of specific projects,it was concluded that the integrated station of hydrogen production and hydrogenation by thermal electricity coupling electrolytic water has certain feasibility in terms of space layout,process flow and market prospect,which can provide a reference for the flexible transformation of power plant and regional hydrogen energy development.
