Green hydrogen is gaining traction globally as a zero-emission fuel with the potential to revolutionize industries, particularly the automobile sector. IRENA identifies two key approaches to national hydrogen strategies - the 'silver bullet' approach advocates for widespread hydrogen adoption across industries, while the 'champagne' approach focuses on selective high-value uses to avoid investing in impractical areas. Nations like Australia, Canada, and the UK prioritize the 'silver bullet' approach, leveraging their production-based economies to drive sustainability goals. On the other hand, countries with strong renewable resources, such as Austria and Kenya, adopt the 'champagne' approach for targeted hydrogen usage in specific sectors like aviation and high-temperature industrial processes. Green hydrogen addresses challenges in 'hard-to-abate' sectors like steel and cement industries, offering a low-carbon alternative and economic opportunities globally. Additionally, countries view green hydrogen as a means to sustain economies, develop new export markets, and enhance energy security by reducing reliance on imported fuels.
