AM Green and Mitsui have announced signing a Memorandum of Understanding (MoU) to explore strategic collaboration and broader energy transition opportunities, and potential investment pathways across low-carbon aluminium.

AM Green, via its wholly-owned subsidiary, AM Green Aluminium Metals and Materials, is building a 1 million tonnes per annum (MTPA) primary aluminium smelter and 2 MTPA alumina refining and mining operations. In November 2025, AM Green signed an MoU with Andhra Pradesh (AP) government to set up 1 MTPA green aluminium complex in AP.

Both aluminium smelter and alumina refinery will be powered by renewable wind and solar firmed up by pumped hydro storage. In May 2025, Coal India signed an MoU to supply 4.5 GW renewable power to AM Green for its various verticals including AM Green Metals.

Under the MoU with Mitsui, the parties will assess potential investment in the AM Green Metals value chain. Mitsui investment will support equity requirements to build the world’s first integrated green aluminium production platform.

As part of the discussions, AM Green and Mitsui will explore a range of commercial and strategic opportunities. This will include offtake of low-carbon aluminium, including potential access to offtake rights associated with AM Green’s green aluminium business. It will also cover supply of auxiliary materials for green aluminium smelter and alumina refinery.

Mahesh Kolli, Founder, Greenko Group and AM Green, said, “AM Green is building globally competitive platforms across molecules and materials to enable industrial decarbonisation at scale. We are pleased to partner with Mitsui to explore collaboration pathways that can accelerate low-carbon aluminium and expand market access for a wider set of green products.”

Anil Chalamalasetty and Mahesh Kolli, the founders of Greenko, have established AM Green as a new energy transition and decarbonisation platform. AM Green holds stake in the Greenko business, in its Power2X businesses (5 MTPA Green Ammonia, Green Hydrogen, Green Metals and Aluminum and Green Chemicals) and in its Bio2X businesses (2G ethanol, SAF, Dissolving pulp and Lignin), it said.

Greenko has a near-term operational renewable energy capacity of over 12 GW across solar, wind and hydro and is building 100 GWh of single cycle pumped hydro storage capacity by 2030 across India, the company stated.

It further added that AM Green is committed to producing 5 MTPA of green ammonia capacity by 2030 (1 MTPA under construction), representing one-fifth of India's green hydrogen production target and 10 percent of Europe's green hydrogen import target. It is also committed to building 1 MTPA of green aluminium capacity.
