The green hydrogen is prepared by adopting an electrolysis water mode, and the product does not contain any carbon element, so that the green hydrogen is a zero-carbon energy source. Existing modes of hydrogen production by water electrolysis are mainly four, but only two methods of alkaline water electrolysis hydrogen production (AWE) and proton exchange membrane hydrogen Production (PEM) are mature in the current commercial technology.
For the field of offshore hydrogen production, the main application is still offshore wind power hydrogen production. China, the United states, european Union, england, japan, australia and other countries or organizations have all issued their own offshore wind power hydrogen production strategy.
