Green hydrogen, derived from renewable sources, is poised to revolutionize the energy transition by replacing fossil fuels in critical sectors and offering storage solutions for excess renewable power. The European Union and individual countries have set ambitious targets for renewable hydrogen, aiming to enhance energy security and reduce emissions. However, challenges such as high production costs, safety concerns, technology immaturity, and regulatory complexities hinder progress towards these targets. Countries like Spain, Portugal, and The Netherlands are leading in meeting their 2030 goals, while others struggle with the transition. Despite uncertainties in the business case and financing, green hydrogen presents a promising solution for decarbonization and grid flexibility. Addressing infrastructure needs, improving technology maturity, and streamlining regulations are crucial steps towards a sustainable future powered by green hydrogen.
