The global imperative for climate change mitigation has propelled the adoption of sustainable energy solutions, with hydrogen emerging as a crucial alternative to fossil fuels. Green hydrogen, produced through water electrolysis powered by renewable sources, offers a clean and sustainable energy solution with high storage efficiency. Technological advancements are driving down production costs, making green hydrogen increasingly feasible as a primary energy source. Nations like Germany, Japan, and Australia are leading the way in investing in green hydrogen infrastructures. Algeria, with its abundant natural resources and solar potential, is poised to play a significant role in green hydrogen production. Recent studies challenge the assumption that the southern desert is the optimal location, highlighting the untapped potential of northern Algeria with its sustainable water resources. The country has initiated projects like MedHySol and HySolThane to integrate green hydrogen into its energy economy, emphasizing a strategic shift towards sustainable energy solutions and regional leadership in the energy transition.
