Rio Tinto and AMG Metals & Materials (AMG M&M), an energy transition solutions provider, have signed a Memorandum of Understanding (MOU) to assess jointly the feasibility of developing an integrated low-carbon aluminum 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 a 1 million tonnes 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 tonnes per annum primary aluminum smelter in a favorable location in India.

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.
