The article discusses the increasing global interest in hydrogen as a clean energy solution to combat climate change. Hydrogen, especially green hydrogen produced from splitting water using renewable sources, is seen as vital for decarbonizing industries like heavy transportation, steel production, and chemical manufacturing. The race for green hydrogen technology is fueled by advancements in electrolyzer technology, declining renewable energy costs, and supportive policies. Companies are focusing on reducing capital and operational costs of electrolyzers to make green hydrogen more competitive with traditional hydrogen production methods. Notable regions like the EU, Japan, China, South Korea, and the US are heavily investing in hydrogen infrastructure and technology, aiming for net-zero emissions targets. However, challenges such as high production costs, transport issues, and the need for technological advancements persist. Collaboration between governments, research institutions, and private companies is essential to drive down costs and scale up green hydrogen production. The article emphasizes Malaysia's need to establish a robust research and development alliance on green hydrogen to stay competitive in the global energy transition.
