Recent energy strategies have prioritized sustainable solutions to combat climate change, focusing on reducing carbon emissions and transitioning from fossil fuels to renewable sources like wind, solar, and geothermal. Wind power, a cost-effective and rapidly growing renewable energy technology, is envisioned to meet half of the world's electricity needs by 2050. Concurrently, green hydrogen has emerged as a clean energy carrier with zero emissions and a significantly higher energy density than fossil fuels, spurring the development of offshore wind-hydrogen systems. These systems combine offshore wind farms with hydrogen production platforms, showcasing innovative approaches like France's Sealhyfe and the Netherlands' PosHYdon projects. While these initiatives demonstrate promising advancements, the OWHS industry is still in its early stages and faces challenges such as environmental impacts, economic viability, and technical obstacles. To overcome these hurdles, further research and optimization efforts are crucial, considering factors like local infrastructure, energy prices, and seawater pre-treatment to ensure efficient hydrogen production. Various studies have explored the feasibility, economics, and environmental effects of OWHS, highlighting the potential for green hydrogen to decarbonize marine and offshore industries. Overall, offshore wind-hydrogen systems represent a significant step towards sustainable energy transformation, offering a pathway to achieve global decarbonization goals.
