Thank you for that very good question, Mr. Martel.
I'm going to link it to a question I was asked earlier by one of your colleagues.
Canadian plants underwent a wave of modernization over the past 15 years. The average age of these plants today is 35 years. We are accordingly reaching a decisive turning point at which we need to consider a new wave of investment, meaning that once again, billions of dollars will be required for large plants like aluminum smelters.
It's a paradox for us really. There is growth in market demand and, as I explained at the outset, we are in a very good position in terms of our carbon footprint and our human footprint.
However, when you have billions of dollars to invest, a key question has to be addressed. Should the major investment plan be launched today using current technologies, or is it better to wait in order to be able to do it with zero-carbon technology, which looks to the future and would be used by companies for the next 25, 30 or even 50 years?
We are thinking here about the ELYSIS corporation's technology, which is still at the research and development phase in Saguenay, but which is looming on the horizon as something that can be used on an industrial scale. It's expected that the technology will be ready to go between 2024 and 2026, which is fairly soon.
In terms of investment, you have to ask the same questions you would ask when buying a car, because it's the same situation. Should you buy an electric vehicle today, which would meet needs for the next 25 years, or buy a traditional gasoline vehicle and wait a few years to make sure that when you buy an EV, it will meet future needs? That's where we are today.
