Summary of Differences Between Hydrogen Production From Offshore Wind Power and Direct Outward Transmission of Electric Energy

Abstract

In order to achieve the goals of the proposal of carbon peaking and carbon neutrality, the government is vigorously developing clean energy such as wind power. The large-capacity offshore wind power development is an important direction for the future development of wind power. However, the electrical energy transmission and grid connection of large-capacity offshore wind power has become the main bottleneck restricting the rapid development of offshore wind power. A strategy was proposed to use hydrogen energy instead of wind power for offshore energy transmission, where the electrical energy was converted into hydrogen energy on-site through electrolytic hydrogen production technology and the hydrogen transmission pipelines were constructed to transport hydrogen to land. The technical routes and application status of the traditional transmission method and hydrogen transmission method were introduced, respectively. Comparing the economic and technical differences between the power transmission method and the hydrogen transmission method, the pipeline hydrogen delivery greatly reduces the construction difficulty and construction cost compared with the offshore power transmission. Three application prospects of offshore wind power electrolysis for hydrogen production were analyzed to help achieve the carbon peaking and carbon neutrality goals as soon as possible.
