Dedicated large-scale floating offshore wind to hydrogen: Assessing design variables in proposed typologies

To achieve the Net-Zero Emissions goal by 2050, a major upscale in green hydrogen needs to be achieved; this will also facilitate use of renewable electricity as source decarbonised fuel hard-to-abate sectors such industry and transport. Nearly 80% world's offshore wind resource is waters deeper than 60 m, where bottom-fixed turbines are not feasible. This creates significant opportunity couple high capacity factor floating hydrogen. In paper we consider dedicated large-scale farms for production with three coupling typologies; (i) centralised onshore electrolysis, (ii) decentralised (iii) electrolysis. The typology design based on variables including for: electrolyser technology; platform; energy transmission vector (electrical power or pipelines). Offshore pipelines assessed economical large distant farms. typology, employing semi-submersible platform could accommodate proton exchange membrane deck; would negate need an additional separate structure export compression enhance dynamic operational ability. It flexible; if one (or turbine) fails, can easily continue other turbines. facilities flexibility further expansion it very much modular system. Alternatively, less complexity associated which may employ electrolysis facility farm spar-buoy platforms water depth locations.
