Hydrogen is gaining momentum in India’s energy transition. With the announcement of the National Hydrogen Mission in 2021, India aims to become a green hydrogen hub backed by ambitious renewable capacity additions. This will require technological advancements in all forms of hydrogen production, storage, and transportation. IHS Markit expects green hydrogen to be cost-competitive with blue hydrogen production by 2030 in developed economies. What are the key focus areas for India to consider to make the National Hydrogen Mission a reality? Are there any early technological sign posts that are promising for reducing hydrogen costs? How can existing business models and infrastructure support initial uptake of hydrogen in India? What should India do to create reliable supply-chains to manufacture critical components, such as electrolyzers?
