Green hydrogen: Alternate fuel for Indian energy basket

Abstract

Hydrogen has emerged as an alternative feasible substitute for green economy in India. The production and transportation of green hydrogen are reviewed extensively in this study. The constraints related to policy framework and remedies for the same are discussed. Comparative outlook of green hydrogen in lieu of Indian economy is shared. Considering the automotive sector's phenomenal economic and environmental significance, the introduction of renewable fuels will be essential in achieving long-term mobility globally. Hydrogen has the potential to be a feasible and effective fuel for green economy since it is abundant, sustainable, safe and inexpensive. Hydrogen proves to be an alternative chemical fuel that will potentially replace fossil energy, due to a number attributes like increased energy density, abundance, ease of transportation, a variety of different manufacturing processes from clean renewable energy fuels with zero or negligible emissions. Internal combustion engines that uses hydrogen could help optimize efficiencies, provide larger power outputs per vehicle, and produce fewer greenhouse gases. The production methods and transportation of green hydrogen are reviewed in this study. The study critically addresses the impact of green hydrogen on the environment, as well as the hazards and safety issues. The study also discusses the challenges associated with the green hydrogen and deliberates on the pillars for developing policies and the strategies for green hydrogen in India. Graphical abstract
