Hydrogen Sheng Energy's Offshore Wind Power PEM Hydrogen Production and Storage System Successfully Completes Long-term Sea Trial

Recently, the real-sea trial of an offshore wind power PEM hydrogen production and storage system, delivered by Shanghai Hydrogen Sheng Chuanghe Energy Technology Co., Ltd., was successfully conducted at the offshore test site in Yazhou Bay, Sanya. This sea trial is the first continuous, long-term real-sea test lasting 720 hours in China targeting an offshore wind power PEM hydrogen production and storage system. This milestone breakthrough marks the official entry of China's offshore wind power coupled with green hydrogen technology into a critical phase of industrial application.

During the sea trial, the test vessel encountered rare stormy weather with waves exceeding grade 4 and winds exceeding grade 6, causing the vessel to tilt at an angle exceeding 10 degrees. As of now, the hydrogen production and storage system has been operating safely and continuously at sea for over 240 hours, with all system equipment functioning normally.

The development and real-sea trial of the offshore wind power hydrogen production and storage equipment system were jointly accomplished by Hydrogen Sheng Energy, the overall project leader, the Ocean Engineering Team of Shanghai Jiao Tong University, and the project owner, Shanghai Survey and Design Institute Co., Ltd. of China Three Gorges Corporation.

During this real-sea trial, under the organization and coordination of the Ocean Engineering Team of Shanghai Jiao Tong University, the overall project leader, and the owner, Shanghai Survey and Design Institute Co., Ltd. of China Three Gorges Corporation, the PEM hydrogen production and storage system was comprehensively tested for reliability and stability under extreme conditions such as large-angle limit motion and severe fluctuations in wind power in the marine environment of the South China Sea, characterized by high temperatures, humidity, and salinity. Valuable operational data and experience were obtained in areas such as offshore electrolytic hydrogen production, hydrogen storage, and safety protection. It is expected to achieve breakthroughs in key technologies, including highly adaptive hydrogen production and storage in marine environments, efficient operation control of hydrogen production and storage equipment under variable load conditions, integration of multifunctional and complex equipment systems in limited spaces, and real-time data monitoring and safety prevention and control. This provides critical technical support and practical basis for constructing an integrated system for the production, storage, and transportation of hydrogen from offshore renewable energy, effectively propelling China's offshore green hydrogen industry towards large-scale and engineering development.

Currently, the global energy system is gradually transitioning from a traditional system dominated by fossil fuels to an efficient, renewable, and low-carbon energy system. Hydrogen energy, as a clean, efficient, and sustainable secondary energy source, is one of the most promising clean energy options.

The offshore wind power hydrogen production technology converts seawater into hydrogen energy by locally consuming offshore wind power, establishing a comprehensive energy system that deeply integrates marine renewable energy with hydrogen energy. This technology can effectively address multiple challenges in the large-scale development, long-distance transmission, and efficient consumption of renewable energy in deep and distant seas. It not only achieves efficient conversion and storage of clean energy but also opens up new pathways for the development and utilization of offshore energy, becoming a core focus for technological innovation in global marine clean energy and a strategic pivot for the green transformation of the future marine economy.
