Description
Summary:	Given the need to reduce carbon emissions, research related to hydrogen production using renewable energy sources has increased in the last few years by academia and industry. Hydrogen production using offshore wind energy has shown high potential, however, there are many technological and economic challenges to production using offshore wind power. This research presents a techno-economic model to estimate and analyze the hydrogen production potential and levelized cost of hydrogen using offshore wind energy, considering technical and environmental constraints. The analysis considers two off-grid scenarios, including offshore and onshore hydrogen production using offshore wind energy. The wind turbines’ power and electrolyzers’ efficiency curves are used to estimate energy generation and hydrogen production, respectively. The cost model is developed based on the region characteristics and process configuration. The developed process is applied to the Brazilian coastline as a case study. The results reveal excellent hydrogen potential in regions with water depths of up to 200 m and distances of up to 200 km from the ports. A minimum value of 4.76 $/kg is found in the Northeast region for the offshore scenario. Moreover, hydrogen production in the offshore scenario is more cost-effective than the onshore scenario. Considering the visual impact constraints of 40 km of distance from the coastline, the results present a reduction of around 25% of the hydrogen potential, showing the importance of research and development for floating platforms to support the wind turbines. Additionally, the research indicates that the optimal sizing of the wind farm-electrolysis system can reduce the cost of hydrogen production. The results from the research work can contribute to design strategies and support decision-making for offshore wind-powered hydrogen projects. •Offshore wind-hydrogen production potential in the Brazilian coastline is addressed.•Two scenarios of offshore and onshore hydrogen production are investigated.•The lowest levelized cost of hydrogen is 4.76 $/kg found in the Northeast region.•The offshore scenario represents a lower cost as the distance to the coast increases.•Not matching the wind farm and electrolyzer’s installed capacity is more efficient.
