Abstract
The goals for zero-carbon sustainable industries and the demand for diverse energy matrix have triggered the research for alternative energy sources. Due to its enormous potential, ocean renewables have become the preferred choice, and several works are devoted to the study of offshore hydrogen production systems powered by offshore wind turbines. Although numerous ocean technologies are available, the choice for offshore wind turbines is a direct consequence of the maturity level of this technology without more elaborate technical criteria. The aim of the present work is to review the technologies and the state-of-the art on offshore hydrogen productions systems from a broader perspective. The design key-drivers of this system will be identified and discussed, followed by a multicriteria analysis to assess, and rank each of the available and/or promising technologies for the support structures of the offshore hydrogen production system. A strength, weaknesses, opportunities, and threats (SWOT) analysis is also provided to aid in the discussion of the challenges and opportunities for the design of offshore “green” hydrogen floating systems.
