Reliance Signs USD 3 Billion Green Ammonia Supply Agreement with Samsung C&T

India's Reliance Industries has signed a USD 3 billion green ammonia supply agreement with South Korean construction and engineering company Samsung C&T, described as one of the largest long-term green ammonia offtake agreements globally to date. Reliance will supply green ammonia to Samsung over a 15-year period beginning in the second half of fiscal year 2029.

The agreement forms what Reliance describes as the first in a series of long-term partnerships supporting the scale-up of its New Energy platform, which encompasses renewable energy, energy storage, green hydrogen, and downstream green fuels and chemicals, supported by in-house manufacturing of key clean energy technologies. Green hydrogen and ammonia are considered critical enablers of the clean energy transition, serving as both clean energy carriers and CO2-neutral feedstocks for green chemicals production. The deal follows India's National Green Hydrogen Mission, launched in 2023, which targets 5 million tonnes of green hydrogen production and nearly USD 100 billion of investment by 2030.

The scale of the Reliance–Samsung C&T agreement — USD 3 billion over 15 years — reflects growing confidence in the commercial viability of green ammonia as a global commodity. India's combination of low-cost renewable energy resources, existing petrochemical and industrial infrastructure, and ambition to become a green hydrogen and ammonia export hub makes it a natural supplier to Asian energy markets. Samsung C&T's role as an engineering and construction conglomerate with significant exposure to industrial energy transition projects positions it as a strategic off-taker for green ammonia used in both energy and chemical feedstock applications.

Reliance Executive Director Anant Ambani said the partnership will help scale the company's green hydrogen ecosystem and gigafactories while contributing to India's ambition of becoming a global hub for green hydrogen derivatives. The 2029 supply commencement timeline allows Reliance to build the upstream renewable energy, electrolysis, and ammonia synthesis capacity required to fulfil the agreement. For India's broader green hydrogen and ammonia sector, the Reliance–Samsung deal sets a commercial benchmark and sends a signal to other potential offtakers that India can be a reliable long-term green ammonia supplier. The deal also strengthens the investment case for domestic electrolyser manufacturing and associated infrastructure development.
