Here's a useful analysis for those in metals, packaging, and even for solar power plant developers and EPCs.
Specifically in the renewable energy sector, Alumnium has the potential to replace steel in some parts of the value chain - there are some who advocate use of aluminium solar panel mounting structures in place of steel, for instance. Aluminium finds extensive use already in transmission and distribution infrastructure. Aluminium extrusions will find increasing roles in the EV charging station infra. Its lightweight and corrosion resistance could make it quite attractive for the emerging offshore wind sector (though this is in a nascent stage in India right now).
Aluminium is the second most used metal in the world today, after steel. India is the second-largest producer of Aluminium globally, after China (though we produce only about 10% of what China does, shows how far ahead China is from everyone else!)
If India were to even get to 20% Aluminium production of what China does today, that would mean a 100% increase in our production.
We have large corporates such as Hindalco & Vedanta Aluminium capable of seizing the opportunity and taking the country to the next orbit, with some policy level assistance from the government.
Aluminium, considered a metal with a lower carbon footprint than steel, can be considered an ideal metal for the emerging low carbon economy in India.
