The report highlights how green hydrogen is playing a crucial role in the energy transition, offering a clean energy vector with vast development opportunities. It emphasizes the maturity of production methods like electrolysis, including alkaline and PEM technologies. The report also discusses transportation methods, such as pipelines and trucks, while mentioning the potential of repurposing natural gas pipelines. Energy storage emerges as a key strength of hydrogen, particularly for storing renewable energy over extended periods, despite efficiency losses. Geopolitically, the concentration of raw material suppliers poses risks, necessitating strategic measures for supply security. The report also touches on the challenges in ammonia production, which heavily relies on hydrogen, especially regarding geopolitical tensions and energy crises. Moreover, it delves into regulatory frameworks, detailing the criteria for categorizing hydrogen as renewable, low carbon, or clean, and the related policies in the EU and the US. The EU's Renewable Energy Directives set ambitious targets for renewable hydrogen usage, while the US Inflation Reduction Act provides tax credits for clean hydrogen. The future of green hydrogen seems promising with growing support from regulatory bodies and technological advancements.
