Abstract

The invention belongs to the technical field of energy and chemical engineering, and particularly relates to a wind power-photoelectricity coupling industrial scale stable hydrogen supply system. Thesystem comprises a wind power generation coupling photovoltaic power generation unit, a power storage unit and a water electrolysis hydrogen production unit, which are connected in sequence; and a hydrogen storage unit can be connected behind the units. The capacities of the wind power generation coupling photovoltaic power generation unit, the electric power storage unit and the hydrogen storageunit meet a certain criterion model, so that the feasibility of hydrogen supply system construction can be analyzed, the implementation and transformation of the hydrogen supply system can be guided,the battery capacity is greatly reduced, and the cost is saved. The coupling complementation of wind power and photovoltaic power generation stabilizes the fluctuation of different time scales, the power supply fluctuation is less than 30%, and the hydrogen supply fluctuation is less than 10%. According to the invention, the system can achieve the large-scale stable hydrogen supply, and completesthe coupling of renewable energy and traditional energy and chemical engineering. Compared with a traditional hydrogen production technology, the system has the obvious advantage of 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 a wind power-photoelectric coupling industrial-scale stable hydrogen supply system. Background technique [0002] The mismatch of hydrocarbon elements between coal resources and coal chemical products leads to carbon redundancy in the conversion process of coal, resulting in the problem of high carbon emission intensity in the coal chemical process. Therefore, many researchers explore the process of coal chemical hydrogenation in order to balance the rational use of coal resources and reduce carbon emissions. [0003] The current large-scale production routes of hydrogen include: hydrogen production by coal gasification, hydrogen production by natural gas reforming, and hydrogen production by methane pyrolysis. These technologies are mature and hydrogen supply is stable. However, the traditional large-scale hydrogen production route using chemical resou...
