This report presents an estimation of the financial requirements for India’s fertiliser sector to transition to green ammonia adoption across multiple scenarios, with the goal of identifying low-hanging opportunities, understanding imperatives, and preparing a trajectory for adoption. The report outlines the current landscape of the Indian fertiliser industry and the role of green hydrogen in its decarbonisation. The report examines the sector’s ammonia requirements, India’s reliance on imports of natural gas and ammonia for fertiliser production, the cost structure of conventional (grey) ammonia, and how natural gas pricing influences this. It then explores the financial implications of blending green ammonia into both urea and non-urea fertiliser production, including the associated challenges, incremental costs, and potential impacts on government subsidies. Additionally, it assesses the emissions mitigation potential of green ammonia and concludes with policy recommendations to support green ammonia adoption in India’s fertiliser industry.
