Offshore hydrogen production plant granted AiP by ClassNK

ClassNK has issued Approval in Principle (AiP) for a floating hydrogen production plant that could use sustainable offshore energy to generate green hydrogen.

The concept has been developed by Japan Offshore Design & Engineering Platform Technology & Engineering Research Association (J-DeEP). The system combines the desalination of sea water with electrolysis to extract hydrogen. By using surplus electricity at the wind farm that, at times, exceeds demand requirements on land, the plant can produce green hydrogen using carbon-free sustainable energy from wind.

J-DeEP has been working with Scottish Development International on a feasibility study of a possible plant that could be sited off Scotland’s coast. The project has been identified as one that requires further analysis under the “overseas deployment of high-quality energy infrastructure” initiative being undertaken by Japan’s Ministry of Economy, Trade and Industry.

ClassNK’s safety evaluation of the plant design has been made in line with its existing guidelines and rules covering all aspects of offshore energy development, including Guidelines for Hydrogen Carriers.
