Putting carbon footprint on the road for automotive construction materials

The automotive industry is constantly looking for ways to lower the weight of vehicle structures, improve fuel efficiency, and reduce carbon footprint. This calls for lightweight materials combined with innovative design and construction methods.

What is the ideal material for today’s automotive manufacturers looking to lower emissions, when considering both the production and use phases?

In a first-of-its-kind study, Outokumpu and FKA Aachen set out to investigate the performance of a battery case in a typical electric vehicle over a projected life of 160,000 km when manufactured from three different materials: aluminum, carbon steel, and stainless steel.

The results challenge current thinking. With stainless steel, the carbon footprint of the battery case is around 113% lower than aluminum, and nearly 30% lower than carbon steel, under current recycling regimes and when powered by the EU’s electricity grid mix.
