As the world grapples with the urgent need to address climate change and countries need to meet their NDCs (Nationally Determined Contribution) as part of Paris Agreement, Hydrogen is emerging as one of the key player in the transition to a sustainable, low-carbon energy future.  This presentation explores hydrogen's role in decarbonizing transportation, industry, and power generation. It will cover advancements in production, storage, and distribution, alongside the economic and policy frameworks essential for a robust hydrogen economy.  Case studies will shed insights into current projects and initiatives driving hydrogen adoption, the challenges and opportunities facing the hydrogen industry, and the critical steps needed to integrate hydrogen into our energy systems effectively.
