Abstract

The invention discloses a method for producing hydrogen through water electrolysis driven by offshore wind power, and belongs to the technical field of hydrogen production through water electrolysis. The method for producing hydrogen by electrolyzing water under the driving of offshore wind power comprises the following steps: S1, constructing a hydrogen production plant on an island, and producing hydrogen under the driving of offshore wind power; the real-time hydrogen production rate is calculated according to the power generation power of the wind power plant, the maximum hydrogen production flow in one day is calculated according to the real-time hydrogen production rate, and a hydrogen production plant of the corresponding scale is built; s2, according to the gas transmission flow and the gas transmission pressure, a seabed hydrogen transmission pipeline is built; the diameter of a hydrogen conveying pipeline is determined according to the maximum hydrogen production flow of the hydrogen production plant; and S3, the hydrogen prepared on the island is conveyed to a thermal power plant on the shore through a hydrogen conveying pipeline, and hydrogen energy power generation is conducted. By adopting the method for producing hydrogen by electrolyzing water under the driving of offshore wind power, the problems of high cost and difficult maintenance of a power transmission line caused by directly conveying the offshore wind power in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of hydrogen production by electrolysis of water, in particular to a method for production of hydrogen by electrolysis of water driven by offshore wind power. Background technique [0002] Offshore wind power has developed rapidly in recent years because it does not occupy land resources, and has an open environment and abundant wind energy resources. my country's eastern coastal areas are economically developed and have a huge demand for energy. If offshore wind energy resources can be fully utilized, it will greatly improve my country's energy structure and promote the development of clean energy. However, the development of offshore wind power is currently facing difficulties in transportation. Submarine cable is a very complex large-scale project, and the cost of laying lines and operation and maintenance is relatively high. With the trend of offshore wind power going far and wide, the return cycle of i...
