Process Design of Independent Offshore Wind Power Hydrogen Production

Abstract

[Introduction] The research aims to make full use of the high quality wind resources in the deep sea, solve the problem of wind abandonment of offshore wind power, and provide a possible offshore hydrogen fuel supply for future new energy ships. [Method] The process flow of offshore wind power coupled seawater hydrogen production technology relying on an independent offshore platform was discussed. The key equipment proton exchange membrane water electrolysis hydrogen production system, hydrogen compressor, hydrogen storage tank and some auxiliary equipment process design problems were described, with a brief description of the control scheme of hydrogen production platform, and a preliminary analysis of its economy. [Result] From the angle of process design, the design of offshore wind hydrogen production platform just in a relatively early stage. The supply chain of key equipment is in the initial development period and most of the suppliers did not enter the marine market, suggesting that current process from engineering design to the engineering of offshore floating hydrogen production is not yet mature and the economic benefit of hydrogen production from renewable energy is low. [Conclusion] At the moment, offshore wind power cannot be connected to the grid at a reasonable price, and the application of coupled hydrogen energy of offshore wind power still has a long way to go. Engineering tests are the prerequisite for large-scale engineering.
