Description

technical field [0001] The invention belongs to the field of offshore wind power, and in particular relates to a seawater hydrogen production delivery system and method based on an existing offshore wind farm. Background technique [0002] As a renewable energy source, offshore wind power has developed rapidly in recent years. Offshore wind farms are generally more than 10 kilometers away from the shore. There are not only abundant wind resources in the field, but also abundant seawater resources waiting for human development and utilization. [0003] The electrolysis of water to produce hydrogen technology has a long history. It electrolyzes water to generate hydrogen and oxygen. Hydrogen is the substance with the highest energy density known on the earth. It does not emit carbon dioxide when burned. It can alleviate the problem of global warming and is a solution for future clean energy. One, most of the existing electrolyzed water technologies are based on pure water, an...
