As the demand for clean and sustainable energy sources continues to increase, green hydrogen and ammonia have emerged as significant contenders for low-carbon energy production, playing pivotal roles in the transition towards a sustainable energy framework. This study aims to evaluate the possibility of establishing a hypothetical offshore wind farm with a capacity of 200 MW, integrating Thirteen Vestas V235 wind turbines, each boasting a capacity of 15 MW, to harness offshore wind resources for electricity generation. Additionally, the study investigates the feasibility of utilizing the generated electricity to produce hydrogen through water electrolysis and subsequently supplying an existing ammonia plant, thereby highlighting the effectiveness of offshore wind resources in promoting sustainable energy production and advancing green hydrogen as a viable energy carrier in this region. Utilizing the Wind Atlas Analysis and Application Program (WAsP), offshore wind potential is assessed based on meteorological data from the Arzew land-based station, overcoming the lack of in situ sea level measurements. The results show that the proposed wind farm could yield 908.67 GWh/year of electricity, leading to 19,066 tons H2/year, resulting in the production of 108,040 tons of ammonia per year. The proposed wind farm can supply an ammonia plant with a daily production capacity of 215 tons.
