Why is such a large amount of energy needed to produce aluminium?
After aluminium oxide is extracted from bauxite, an electrolytic reaction follows using cryolite to produce the aluminium. This electrolytic process requires enormous amounts of electrical energy. To put it more tangibly: The production of one ton of primary aluminium consumes on average 15 megawatt hours – as much as a two-person household in 5 years!
Regularly increasing electricity prices in Europe since the beginning of 2021, from formerly 50 €/MWh to sometimes up to 150-250 €/MWh, cost-efficient process management was necessary anyway. Due to the precarious situation in Eastern Europe, many countries are forced to look for alternative energy suppliers, which means that electricity prices will continue to rise.
