The transition to a low-carbon future necessitates innovative approaches to renewable energy deployment, particularly in the marine environment, where abundant resources remain underutilized. This paper explores the potential of hybrid renewable energy systems and green hydrogen production to address the energy challenges faced by Very Small Islands (VSIs). These islands heavily rely on imported fossil fuels, making them vulnerable to global price fluctuations and contributing to economic instability and environmental degradation. Offshore floating platforms present a transformative opportunity by harnessing marine renewable resources, integrating wind, solar, and wave energy to maximize energy production while minimizing land use conflicts. Green hydrogen, produced through the electrolysis of seawater, powered by these renewable sources, offers a sustainable alternative for decarbonizing transportation, particularly in the maritime sector. The study aims to assess the feasibility of converting small conventional passenger vessels to hydrogen propulsion and evaluate the technical, economic, and environmental impacts of deploying offshore platforms for hydrogen production. By examining these aspects, this research contributes to the broader discourse on sustainable energy solutions for island communities and provides actionable insights into implementing renewable hydrogen-based maritime transport.
