Global energy demand is expected to rise steadily, driven by population growth and economic development, with fossil fuels maintaining dominance until at least 2050. However, concerns over greenhouse gas emissions have led to a surge in the global green hydrogen market, valued at USD 3.2 billion in 2021. Green hydrogen, produced via electrolysis powered by renewables, is gaining traction for its role in sustainability and energy storage. Job opportunities in hydrogen-related sectors are projected to increase, further fueling economic growth. While green hydrogen lacks a standardized definition, it is generally characterized by minimal environmental impact. Electrolyzer technologies like PEM, AEM, and SOECs are crucial for advancing green hydrogen production, with ongoing research focusing on efficiency and cost reduction. Despite advancements, challenges such as high costs and material durability persist, necessitating further innovation. A structured analysis integrating recent developments in electrolyzer technologies and the economic and environmental aspects of hydrogen production methods is essential for overcoming obstacles and driving the transition to a green hydrogen economy.
