Aluminium is a lightweight metal
Aluminium is a lightweight metal with a tonne of different uses: from aircraft, to buildings, to drink cans. And most important from my perspective is that it’s used in a number of technologies related to the energy transition. These include: electricity networks, battery packs, solar power and electric vehicle chassis. Demand for these technologies is projected to increase enormously over the coming decades, and aluminium production will have to increase along with it. Unfortunately, aluminium production is also responsible for more than a gigaton of CO2 globally in 2021, nearly 3% of total global emissions.
Since we’re going to need aluminium as a part of the transition, we can’t exactly stop producing it. That means we need to find ways of producing it without the CO2. Fortunately, engineers are figuring out ways of doing just that, and in this video I’ll explore what technologies we’ll use to eliminate emissions from aluminium production.
