Hydrogen has long been recognised as a pathway to deep decarbonisation, particularly in hard-toabate sectors. Rapid scale-up of renewable energy systems, solar energy, in particular, resulting in precipitous cost reduction, has made a ‘Green’ Hydrogen-based economy a real possibility in several geographies. There is a renewed global interest towards this versatile energy resource, with several governments announcing Green Hydrogen policies/strategies/targets and global multilateral/ private sector organisations increasingly recognising Hydrogen in their near-to-midterm strategies.
