Hyderabad, April 17, 2025 – India is poised to become a major hub for green aluminium as AMG Metals & Materials (AMG M&M) and global mining giant Rio Tinto team up to explore a massive low-carbon aluminium production facility powered entirely by renewable energy. The plan includes up to 1 million tonnes per annum (Mtpa) of primary aluminium capacity and 2 Mtpa of alumina production, positioning the project among the largest of its kind globally.
The two companies have signed a Memorandum of Understanding (MoU) to jointly assess the feasibility of the integrated project. The proposed development will be driven by solar and wind energy, backed by pumped hydro storage – a hallmark of India’s ambitious energy transition efforts.
The first phase under consideration involves a 500,000 tonnes per annum aluminium smelter, to be developed at a strategic site in India, supported by firmed renewable power through AMG M&M’s affiliate Greenko. Simultaneously, Rio Tinto will evaluate options for a cost-efficient commercial alumina supply chain.
Rio Tinto, AMG Plan One of World’s Largest Green Aluminium Projects
The collaboration signifies a strong step forward in addressing the rising global demand for low-carbon, recyclable materials, particularly in sectors like automotive, construction, packaging, and transportation. With global aluminium demand nearing 70 Mtpa, India—already the second-largest producer and third-largest consumer—is expected to double domestic demand within a decade, making this project both timely and transformational.
Rio Tinto Aluminium Chief Executive Jérôme Pécresse emphasized the importance of emerging markets in diversifying and decarbonizing the aluminium supply chain, stating:
“India’s fast-growing economy and renewable potential make it a compelling choice for sustainable aluminium production.”
Mahesh Kolli, Group President of AMG M&M and Greenko, added:
“We’re excited to bring large-scale decarbonization to the materials space. This project can reshape global supply chains with sustainable metals at scale.”
The venture underscores India’s growing role as a global clean-tech powerhouse, with AMG and Greenko leading projects across green hydrogen, ammonia, e-fuels, and renewable power infrastructure.
Rio Tinto is a leading global mining and metals group that focuses on finding, mining, processing and marketing the Earth’s mineral resources. Its main products include iron ore, aluminium, copper, lithium, borates and titanium dioxide.
AMG Metals & Materials is incorporated by Anil Chalamalasetty and Mahesh Kolli, the founders of Greenko Group, one of India’s leading energy transition solutions providers, and AM Green, a global decarbonization solution provider.
Greenko has a near-term operational renewable energy capacity of 10 GW across solar, wind and hydro and is building 100 GWh of single cycle storage capacity across India. AM Green is developing low-carbon ammonia projects across multiple locations in India with a goal to reach 5 Mtpa of green ammonia capacity by 2030. Its first plant currently under construction in Kakinada with a projected capacity of 1 Mtpa of green ammonia will be one of the world’s largest RFNBO compliant green ammonia facilities, supporting efforts to achieve net zero targets both in India and OECD markets.
AM Green is also developing production capabilities for other net zero molecules and chemicals including green caustic soda, e-methanol, olefins & biofuels for decarbonization in hard to abate industries.
