A REVIEW ON HYDROGEN PRODUCTION FROM OCEAN RENEWABLE ENERGY AND THE APPLICATION STATUS

Ocean renewable energy development is strategically significant to the world's low-carbon energy transformation. Many ocean renewable energy development projects have been carried out or are under planning. Combining green hydrogen and ocean renewable energy is ideal for developing ocean renewable energy. This paper first surveyed the main ocean renewable energy hydrogen production projects worldwide. Detailed information about these projects' technical routes and the scale of renewable energy development were then summarized. With ocean renewable energy development gradually moving towards greater offshore distance and water depth, large-scale and low-cost ocean renewable energy development has become a critical concern in industry and academia. Therefore, a comparison about the energy transmission mode is then carried out. Furthermore, based on the current ocean renewable energy development projects, the development trend of hydrogen production from ocean renewable energy was analyzed, including increased offshore distance and water depth, development of floating wind platforms, and large-scale wind turbines. Meanwhile, the main technical challenges are discussed in detail to achieve large-scale and low-cost ocean renewable energy development.
