Solid hydrogen storage system and hydrogen storage method adopting offshore wind power hydrogen production coupling hydrate method

The invention relates to an offshore wind power hydrogen production coupling hydrate method solid hydrogen storage system and a hydrogen storage method, the system comprises a seawater desalination system, an offshore hydrogen production system and a hydrate method solid hydrogen storage system, the seawater desalination system uses seawater as a raw material to carry out desalination treatment to obtain fresh water, and the offshore hydrogen production system electrolyzes the fresh water through wind power generation to generate hydrogen; according to the hydrate method solid hydrogen storage system, hydrogen reacts with a thermodynamic accelerant and a dynamic accelerant to generate a hydrogen-containing hydrate, and solid storage of hydrogen is achieved. Solid hydrogen storage is carried out in a mode of generating hydrogen-containing hydrates through reaction after wind power generation hydrogen production is carried out on the sea, high-density safe storage and transportation are achieved, no pollution i
