The deal is valued at over $3 billion, with supplies expected to begin in the second half of FY29, the conglomerate said in a regulatory filing.
The agreement is among the largest long-term green ammonia offtake deals globally and comes as countries such as Japan and South Korea increasingly look to low-carbon fuels like hydrogen and ammonia to reduce emissions from industries and power generation.
Green ammonia is produced by combining nitrogen with hydrogen generated using renewable electricity. It is considered a low-carbon fuel and an efficient medium for transporting hydrogen.
Reliance Industries
said the partnership will support the development of its green hydrogen ecosystem and related manufacturing facilities.
The company is building a clean-energy manufacturing ecosystem that includes solar modules, battery energy storage systems, and electrolysers.
It added that the agreement with Samsung C&T is the first in a series of long-term offtake partnerships aimed at scaling up the company’s New Energy platform.
“We are proud to partner with Samsung C&T to supply green ammonia that is cost-competitive and reliable. This partnership marks an important step in India’s clean-energy journey,” said Anant Ambani, Executive Director at Reliance Industries.
Reliance had earlier announced plans in 2021 to invest $10 billion in renewable energy, hydrogen, and battery storage as it seeks to expand beyond its traditional oil-to-chemicals business.
Shares of Reliance Industries settled 0.96% higher on Monday at ₹1,394. The stock is down about 12% so far in 2026.
