Green hydrogen is a promising technology that has been gaining momentum in recent years as a potential solution to the challenges of transitioning to a sustainable energy future [4, 5].The concept of green hydrogen refers to the process of producing hydrogen gas through electrolysis, using renewable energy sources such as solar, wind, or hydroelectric power.
The global energy mix highlights a stark reliance on fossil fuels, which accounted for 78.5 % of final energy consumption in 2020. Meanwhile, renewable energy (RE) sources contribute a mere 12.6 % of the total (Bourcet, 2020, Nan et al., 2023).Therefore, This imbalance emphasizes the significant potential for growth in RE adoption to mitigate climate change impacts, driven

Four renewable energy sources are used for green hydrogen and power production. There, electrical direct current (DC) is produced by the electrochemical reaction of hydrogen and oxygen, and the inverter transforms it into alternating current (AC). Then, the stack temperature increases because the electrochemical reaction is exothermic.
The resulting hydrogen can then be stored efficiently – as compressed hydrogen gas, in liquefied form, or converted to ammonia or methanol – to be used later, for example in fuel cells that provide electricity when renewable sources are
