The article discusses the potential of green hydrogen as a clean fuel in achieving net-zero emissions, particularly focusing on India's transition to this sustainable energy source. It highlights the significance of green power and clean water availability for green hydrogen production. By comparing India's biofuel challenges to the current green hydrogen scenario, the article emphasizes the need for efficient feedstock processes and genetic engineering to enhance production capacity. Water scarcity in India, exacerbated by excessive groundwater use, poses a significant hurdle in green hydrogen development. The article suggests utilizing seawater for electrolysis as a solution, alongside emphasizing the importance of water-efficient agricultural practices and policy interventions to conserve freshwater resources. Corrosion issues in saltwater electrolysis are identified as a barrier to mass green hydrogen production, urging the development of advanced electrocatalyst technology through R&D investments. The article concludes that India needs to focus on indigenous technology development to achieve its green hydrogen goals and reduce reliance on imports.
