A recent study from the University of Sheffield highlights the leadership of the United States and China in advancing hydrogen development within the G20. The study, published in the journal Renewable and Sustainable Energy Reviews, assessed hydrogen legislation, investment, and strategies across G20 nations to gauge their progress in establishing hydrogen economies. The research found that the US and China are at the forefront, with the UK, the EU, and Canada closely following. However, disparities were noted in hydrogen standards and policies across G20 countries. Only a few nations such as China, the US, and the UK have updated hydrogen standards, while others like Brazil, India, Indonesia, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, and Turkey lack any legislation in this regard. The study underscores the importance of establishing an internationally recognized hydrogen standard to accelerate the development of low carbon hydrogen fuels. Professor Lenny Koh from the University of Sheffield emphasized the significance of creating unified standards to facilitate a cohesive market and accelerate the transition from fossil fuels to hydrogen. Dr. Moein Shamoushaki highlighted that targeted investments based on the research findings are crucial for effective hydrogen legislation and policy-making. The call for a standardized approach within the G20 aims to address the existing gaps in hydrogen economies and provide guidance for future investments and policies.
