The article discusses the growing importance of low-carbon hydrogen in the transition towards a net-zero society. McKinsey consultancy forecasts a substantial increase in global hydrogen demand by 2050, with the potential to mitigate more than 20% of global emissions. Currently, hydrogen is used in industries like steelmaking and oil refining but is mostly produced from methane, leading to CO₂ emissions. Efforts are being made to develop technologies that reduce production costs and capture CO₂ simultaneously. Challenges in hydrogen transportation are addressed by converting it to ammonia for easier distribution. Blue hydrogen, which involves CO₂ capture from existing production, is highlighted as a viable mid-to-long-term solution. Governments are urged to implement policies to support lower-emission hydrogen projects, including infrastructure development and regulatory changes. The focus on collaboration, technology, and policy support aims to accelerate the growth of a global hydrogen market and facilitate the energy transition.
