Rio Tinto signed a Memorandum of Understanding (MOU) with a partner to assess the feasibility of developing an integrated low-carbon aluminum project that is powered by renewable energy in India. 

The mining company signed the MOU with AMG Metals & Materials (AMG M&M), an energy transition solutions provider.

The two companies will consider the potential development of up to a 1 million tons per annum (Mtpa) primary aluminum 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 tons per year primary aluminum smelter in a location in India.

“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,” said Rio Tinto Aluminium Chief Executive Jérôme Pécresse in a statement. “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.
