The study conducted by researchers from Sapienza University of Rome delves into the intricate dynamics of offshore wind energy coupled with hydrogen production, aiming to address the challenges and intricacies of sustainable energy supply. The research specifically focuses on utilizing PEM electrolyzers powered by offshore wind farms and Lithium-ion batteries to produce hydrogen. To facilitate this analysis, a digital twin is constructed using Python to support sizing considerations and conduct a comprehensive techno-economic assessment. An energy flow management controller is devised to handle hourly energy dynamics effectively. By examining three distinct scenarios where the electrolyzer capacity caters to a steel plant's hydrogen demand at varying percentages of the wind farm capacity (40%, 60%, and 80%), the researchers optimize the layout while considering turbine wake effects. The findings indicate that allocating 80% of the wind farm capacity to the electrolyzer leads to a superior energy balance, with 87.5% of wind energy utilized for hydrogen production. However, the study highlights the limited storage capability of hydrogen in this context, with energy storage remaining below 5% across all scenarios. Despite minor differences in the Levelized Cost of Energy (LCOE) and Levelized Cost of Hydrogen (LCOH) among scenarios, the research underscores the substantial environmental benefits. The analysis reveals significant carbon emission reductions, with 268 ktonCO2/year saved through wind power and 520 ktonCO2/year through hydrogen production. This emphasizes the pivotal role of hydrogen in mitigating emissions in challenging sectors like steel manufacturing, which struggle with traditional decarbonization methods. Overall, the study showcases the potential of integrating offshore wind energy and hydrogen production to advance towards a more sustainable and eco-friendly energy landscape.
