Recently, Yingchuang Sanzheng (Yingkou) Fine Chemical Co., Ltd. and Zhejiang Gaocheng Green Energy Technology Co., Ltd. signed the largest chemical hydrogen energy storage power station project in China in Yingkou City, Liaoning Province. The total power of the power station is 10MW.
The 10MW hydrogen energy storage power station project is carried out in two phases. In the first phase, the design and construction of a 2MW hydrogen energy storage power station will be completed. The power station uses five modules connected in parallel, and each module is composed of five fuel cell stack modules connected in parallel. Damage to any one stack or module will not affect the normal operation of other stacks or modules. At the same time, through the cut-off function, any module can be shut down for maintenance.
The power generation system of this power station is mainly composed of a fuel cell stack power generation unit and a water and heat management subsystem. The hydrogen-to-electricity conversion efficiency is greater than 58%. At the same time, the effective heat power collected by the waste heat recovery system exceeds 1,300kW. Through the interconnection and complementation of electric energy and thermal energy, the comprehensive energy utilization rate exceeds 90%.
The life of the power station is more than 15 years, and the fuel cell life is as long as 60,000 hours. It can generate about 16 million kW·h per year (calculated based on 330 days * 24 hours), save more than 10 million yuan in electricity bills (calculated based on the 2021 park power grid selling price), and reduce carbon dioxide emissions by more than 12,000 tons. When the power is sufficient, power can also be supplied to the battery to replenish power, and the battery can be charged and maintained for self-maintenance.
In addition, the power station is also equipped with a complete safety monitoring system, including hazardous gas monitoring, flame detector , smoke detector , audible and light alarm and other firefighting supporting facilities. At the same time, for fuel leakage, it is necessary to Early warning protection functions are set for fault conditions such as voltage and overload.
