When you do aluminum, the first step is to mine bauxite. Typically, bauxite mines are close to the equator. Then, you put this bauxite in an aluminum refinery, where you do some processing, cleaning, washing and heating. From that bauxite, you produce alumina, which is what we are doing in Saguenay—Lac-Saint-Jean and Vaudreuil. Then, when you have alumina, you put it in a pot for an electrolysis process whereby, using a carbon anode, you produce aluminum.
You have CO2 emissions all over the chain. However, by far the biggest part of emissions is from the electrolysis process, with two sources. The first is the massive use of electricity needed for that process. For this reason, the source of electricity matters, and we have clean electricity in Saguenay—Lac-Saint-Jean. The second is the carbon itself dissolving, which releases CO2 into the atmosphere. This is what you are trying to tackle with ELYSIS.
