English
This paper presents a conceptual design of hydrogen power systems for a 73 m offshore wind Service Operation Vessel (SOV), replacing fossil fuel systems with a hybrid of PEM fuel cells and lithium-ion batteries. Twenty-six 200 kW PEMFC units and 2.6 MWh batteries fit within existing engine room constraints. Among four hydrogen storage options, LH2 and LNH3 are technically viable, with LNH3 offering 30% lower total cost of ownership. The design could cut up to 17,600 tonnes of CO2 annually per vessel.

📄 Abstract（原文）
Decarbonising offshore wind operations represents a critical step toward achieving net-zero emissions in the maritime and energy sectors. Service Operation Vessels (SOVs), which provide essential maintenance support to offshore wind farms, are currently dependent on conventional fossil fuel power systems that contribute significantly to operational greenhouse gas (GHG) emissions. This paper presents a conceptual design of hydrogen power systems for a 73 m offshore wind SOV. The design explores replacing conventional power systems with a hybrid system combining hydrogen proton exchange membrane fuel cells (PEMFCs) and lithium-ion batteries, achieving equivalent performance with zero operational emissions. The analysis retains the vessel’s original layout and subdivision to enable a like-for-like comparison between conventional fossil fuel and hydrogen-based systems. A total of twenty-six 200 kW PEMFC units and 2.6 MWh battery packs were identified as an optimal configuration within the existing engine room constraints. Four hydrogen storage technologies, compressed hydrogen (CH2), liquid hydrogen (LH2), liquid ammonia (LNH3), and metal hydrides (MH), were evaluated in terms of volumetric feasibility, safety, and cost. Among these, LH2 and LNH3 were found technically viable, with the LNH3-based system offering a 30% lower total cost of ownership than the LH2 alternative. The paper also discusses the synergies between offshore wind farms and green hydrogen and ammonia production, highlighting that Australia’s offshore wind projects in the Bass Strait area could generate renewable hydrogen and ammonia to sustain zero-emission SOV operations. The findings demonstrate that integrating hydrogen fuel technologies with offshore wind supply chains offers a practical pathway to decarbonise offshore operations, reduce lifecycle emissions by up to 17,600 tonnes of CO2 annually per vessel, and accelerate the transition toward a sustainable blue economy.
