In the midst of global climate action, the urgency to transition towards sustainable development is highlighted. Asia, especially Japan, is leading the charge in embracing green technologies for a more environmentally friendly future. The article discusses the prominence of Chinese EVs in Asia and Europe, Malaysia's increasing adoption of EVs, and Sarawak's advancements in energy transition through the National Energy Transition Roadmap. A significant focus is placed on Japan's efforts to promote clean hydrogen and green steel in alignment with its net zero goals. Hydrogen is identified as a key player in Japan's decarbonization strategy, particularly in hard-to-abate sectors such as steel and transportation. Japan aims to boost hydrogen demand and supply, increase fuel cell technology infrastructure, and reduce the cost of hydrogen significantly by 2050. The government plans to invest heavily in hydrogen supply chains and infrastructure, fostering collaboration between the public and private sectors. The article also delves into Japan's steel industry transformation towards green steel production. Through initiatives like green hydrogen adoption and carbon capture technologies, Japan is striving to achieve complete decarbonization in its steel manufacturing processes. Innovations like the Kobenable Steel by Kobe Steel demonstrate the progress towards sustainable steel production. The holistic approach taken by Japan, from green hydrogen energy to green steel manufacturing, exemplifies a sustainable and comprehensive strategy for combating climate change and achieving a cleaner future.
