India's Reliance Industries has entered a binding, long-term supply and purchase agreement with South Korean trading and investment firm Samsung C&T to supply green ammonia, in a deal valued at $3 billion (approximately €2.59 billion), the Hindustan Times reports.

The 15-year contract, described as one of the largest of its kind globally, is scheduled to commence deliveries in the second half of the fiscal year ending March 2029. The agreement represents the first in a series of anticipated off-take deals intended to scale Reliance's New Energy platform.

Anant Ambani, Executive Director of Reliance Industries, said: "This partnership marks an important step in India's clean-energy journey," adding that the initiative aims to integrate India's renewable resources with manufacturing leadership to produce value-added chemicals at scale.

Central to Reliance's capacity to fulfil the contract is the Dhirubhai Ambani Green Energy Giga Complex in Jamnagar, Gujarat — a 5,000-acre manufacturing hub housing gigafactories for solar modules, batteries, electrolysers, and fuel cells. The company is pursuing deep indigenisation across the clean energy value chain, aligned with India's National Green Hydrogen Mission.

Ambani stated that the company's commitment to indigenising critical energy transition technologies — including solar, battery energy storage systems, and electrolysers — sits at the heart of its strategy under a Make-in-India framework.

For Samsung C&T, the agreement secures a long-term source of carbon-free fuel as North Asian economies accelerate efforts to decarbonise heavy industry and the shipping sector.

The deal provides a revenue roadmap for Reliance's new energy unit as the company works toward its broader goal of reaching net-carbon zero by 2035. Reliance, India's largest private sector company by revenue, recorded a net profit of INR 81,309 crore (€7.56billion) for the year ended March 2025.
