The invention belongs to the field of energy and chemical technology, and in particular relates to an industrial-scale stable hydrogen supply system coupled with wind power and photoelectricity. The system includes a wind power generation coupled photovoltaic power generation unit, a power storage unit and an electrolyzed water hydrogen production unit connected in sequence, and a hydrogen storage unit can also be connected thereafter. Among them, the capacity of wind power coupled with photovoltaic power generation unit, power storage unit and hydrogen storage unit satisfies a certain criterion model. On the one hand, the feasibility of hydrogen supply system construction can be analyzed, and on the other hand, the implementation and transformation of hydrogen supply system can be analyzed. It plays a guiding role, which greatly reduces the battery capacity and saves costs. The coupling and complementarity of wind power and photovoltaic power generation can stabilize the fluctuations of different time scales, the fluctuation of power supply is less than 30%, and the fluctuation of hydrogen supply is less than 10%. The system can realize large-scale stable hydrogen supply and complete the coupling of renewable energy and traditional energy chemical industry. Compared with traditional hydrogen production technology, it has obvious advantages in carbon emission reduction and has reasonable economic benefits.
Description
technical field [0001] The invention belongs to the technical field of energy and chemical industry, and specifically relates to an industrial-scale stable hydrogen supply system coupled with wind power and photoelectricity. Background technique [0002] The mismatch of carbon and hydrogen elements between coal resources and coal chemical products leads to carbon redundancy in the coal conversion process, resulting in a problem of high carbon emission intensity in the coal chemical process. Therefore, many researchers explore the hydrogenation process of coal chemical industry in order to balance the rational use of coal resources and reduce carbon emissions. [0003] The current large-scale production routes of hydrogen include: coal gasification hydrogen production, natural gas reforming hydrogen production, methane pyrolysis hydrogen production and other processes. These processes are mature in technology and stable in hydrogen supply. However, the traditional large-sca...
