Classification society ClassNK has issued an Approval in Principle (AiP) for the design of a floating offshore hydrogen production plant developed by the Japan Offshore Design & Engineering Platform Technology & Engineering Research Association (J-DeEP).
The amount of electricity generated by offshore wind turbines is likely affected by weather conditions, and excess electricity can be generated when supply exceeds demand on land, ClassNK said.
The floating offshore hydrogen production plant developed by J-DeEP combines a seawater desalination system and a system for extracting hydrogen from water by electrolysis.
Using surplus electricity from an offshore wind turbine, the plant produces green hydrogen that does not emit CO2 during the production process.
In collaboration with Scottish Development International, J-DeEP worked on a feasibility study for the proposed installation of the plant near offshore wind farms off the coast of Scotland.
The technical verification of the plant and the initial feasibility study on its commercialization have been retained as one of the “Feasibility studies for the overseas deployment of high-quality energy infrastructure” from the Japanese Ministry of Economy, Trade and Industry in 2021.
ClassNK conducted a safety assessment on the plant design by J-DeEP in accordance with its rules and guidelines. After confirming that the design meets the relevant requirements, ClassNK issued AiP.
