DEC Secures World's First CCS AIP for Wind-Powered Hydrogen Production Platform！

Recently, the integrated floating wind power coupled with seawater hydrogen production without desalination platform, independently developed by Dongfu Research Institute under Dongfang Electric Group, successfully obtained the Approval in Principle (AIP) certificate issued by China Classification Society (CCS), becoming the world's first floating wind power hydrogen production platform to pass this certification.

This platform was independently developed by Dongfu Research Institute. Since H2 2023, relying on its self-developed 17 MW floating offshore wind power platform, the institute integrated the original principle technology in the field of seawater hydrogen production without desalination published by Academician Xie Heping's team in the main issue of *Nature* in 2022, broke through key technologies such as offshore power management, system control, and high-pressure hydrogen storage, and carried out R&D of the integrated floating wind power coupled with seawater hydrogen production without desalination platform.

The R&D team conducted in-depth surveys of advanced domestic and overseas technologies. Focusing on the working conditions in far-reaching seas, the operational requirements of floating wind turbines, and the needs of hydrogen production processes, from the strength of the floating structure to the integration of hydrogen production modules, from system collaborative control to full-process safety protection, each link underwent thorough technical demonstration, and all key parameters were precisely calculated and repeatedly verified, with multiple rounds of iterative optimization of the design scheme.

Among them, innovatively utilizing the semi-submersible platform space, the seawater hydrogen production without desalination system was arranged on a newly built platform between the columns and inside the columns, not only efficiently utilizing the idle space of the columns but also significantly reducing additional construction costs, achieving dual breakthroughs in "space utilization" and "cost control." To address the challenges of harsh sea conditions, the team designed advanced stabilization devices to further enhance the wind and wave resistance of the hydrogen production system, ensuring its safe and stable operation under more complex sea conditions.
