J-DeEp floating hydrogen concept gets approval in principle
April 5, 2022
ClassNK has awarded approval in principle for a concept developed by Japan Offshore Design & Engineering Platform Technology & Engineering Research Association.
TOKYO, Japan– ClassNK has awarded Approval in Principle (AiP) for a floating offshore hydrogen production plant concept developed by Japan Offshore Design & Engineering Platform Technology & Engineering Research Association (J-DeEP).
This design combines a seawater desalination system with equipment that extracts hydrogen from water via electrolysis. Through using surplus electricity generated from an offshore wind turbine, the plant allows production of green hydrogen that does not emit CO2 (carbon-dioxide) during the production process.
J-DeEP, in collaboration with Scottish Development International, has been working on a feasibility study to install the plant close to wind farms offshore the coast of Scotland.
Technical verification of the plant and the initial commercialization study have been adopted as one of Japan’s Ministry of Economy, Trade and Industry’s "feasibility studies for the overseas deployment of high-quality energy infrastructure.”
ClassNK performed a safety evaluation of J-DeEP’s design to verify compliance with its rules*1 and guidelines*2. This led to the issue of the AiP.
