Rio Tinto and AMG Metals & Materials (AMG M&M), an energy transition solutions provider, have signed a Memorandum of Understanding (MoU) to jointly assess the feasibility of developing an integrated low-carbon aluminium project powered by renewable energy in India. AMG M&M is promoted by the two founders of Greenko and AM Green.

Together, the parties will consider the potential development of up to 1 million tonnes per annum (mtpa) primary aluminium smelter and 2 mtpa of alumina production, both powered by renewable wind and solar energy firmed by pumped hydro storage. The development will comprise a study to evaluate a potential first phase 500,000 tonnes per annum primary aluminium smelter in a favourable location in India.

Aluminium is a recyclable environment-friendly metal having a host of applications across diverse sectors - power, transportation, building, construction, packaging and many more. World primary Aluminium demand has reached ~70 million tonnes. India is already the world's second biggest aluminium producer and third biggest consumer, with demand set to double over the next decade. Current India Aluminium market is around 5 mtpa.

Jérôme Pécresse, Chief Executive, Rio Tinto Aluminium, said: “This study is an important step in our ambition to grow our global, low-carbon aluminium footprint while exploring new project delivery approaches and opportunities in emerging markets. Partnering with AMG Metals & Materials enables us to assess how we can develop low-cost responsible aluminium production powered by renewable energy. With its rapid economic growth and strategic position, India is a compelling location for this potential project and aligns with our long-term vision for a globally more diverse and resilient aluminium business.”

As part of the study, AMG M&M will examine a firmed renewable energy solution with Greenko, while Rio Tinto will explore a commercial alumina solution. The study will also assess smelting technology options to determine the most cost-effective solution for the project.

Mahesh Kolli, Group President of AMG Metals & Materials and Greenko, said: “Over the last few years, we have been able to deliver a multitude of decarbonization solutions comprising electricity, molecules, chemicals and fuels. We are excited to expand that further to the materials space. This MOU could deliver much needed low-carbon metal at scale to propel decarbonization initiatives in global supply chains across auto, construction, consumer packaging and many more segments.”
