German utility Uniper has signed a binding long-term offtake agreement for 500,000 t/yr of renewable ammonia from Indian developer AM Green's planned 1mn t/yr plant at Kakinada in Andhra Pradesh.
First deliveries — which will meet the EU's definition of renewable fuels of non-biological origin — are expected as early as 2028, Uniper said. The company did not specify the contract duration.
The deal is "the first of its kind for an Indian company", Uniper said. It follows years of talks after the two firms announced a non-binding agreement for 250,000 t/yr in early 2023.
AM Green took a final investment decision on the plant in August 2024. The firm said the project will come online in two phases, with the first 500,000 t/yr commissioned before a second phase adds another 500,000 t/yr within 6-9 months. The timeline was pushed back from initial expectations to align with EU regulations and offtake commitments, chief executive Gautam Reddy Kumbam said in July 2025.
AM Green has also signed preliminary agreements with BASF, RWE, Norwegian fertilizer producer Yara and Singapore's Keppel.
Uniper said the deal marks a "significant step forward in developing a diversified portfolio of renewable and low-carbon molecules for European customers". The utility is developing its own hydrogen production sites across Europe and plans an ammonia import and cracking facility at Wilhelmshaven in northern Germany.
