"We are pleased to have nominations this year that point the way to a more sustainable future," says Eva Petursson, chair of the Swedish Steel Prize jury and head of research and innovation at SSAB. "Two applications in the field of mechanical batteries use steel in such an innovative way that we couldn't decide between the two. That's why we nominated both."
The finalists and the jury's reasons are as follows:
DigJim from Norway - ultra-fast maintenance system.
This user-initiated innovation is a patented system for the rapid replacement of parts to protect buckets on construction sites. This solution enables new flexible and sustainable ways of working during maintenance. In addition, a modified design of the teeth in the DigJim system makes better use of the wear resistance of the steel. This has led to a demonstrable increase in productivity in the field.
For a new, ultra-fast maintenance system with lower operating costs and higher productivity, DigJim has been nominated for the Swedish Steel Prize 2023.
Gestamp from Spain - front lower control arm
In a very demanding application, Gestamp puts the material properties to the test in terms of strength and formability. This central part of the chassis is crucial for both daily operation and vehicle safety. Using the latest forming technology, the front lower control arm has been given an optimized single-shell design, made possible by the introduction of a new material strength level.
Gestamp has been nominated for the Swedish Steel Prize 2023 for an optimized front lower control arm with better behavior, lower weight and lower cost.
Green Buffers from Sweden - new generation train coupling technology.
Green Buffers introduces high-strength steel for energy absorption between railcars to increase train safety. This new generation in coupler technology enables more complex customized solutions and offers an expanded number of well-defined, robust performance levels for energy absorption. Since existing railcars can be retrofitted, the technology can be introduced quickly and rail safety improved rapidly.
Green Buffers has been nominated for the Swedish Steel Prize 2023 for the new system, which supports the company's vision of zero uncontrolled derailments in collisions.
Levistor from the UK and ZOOZ from Israel - mechanical battery for fast charging.
These high-performance mechanical batteries with a new steel flywheel design are sustainable solutions for a more sustainable world. Mechanical batteries have a longer life, no energy loss and a smaller environmental footprint compared to chemical batteries. This modernized steel solution also achieves safer operation by replacing conventional flywheel designs with layers of high-strength steel, preventing insulation failures and limiting associated damage.
Levistor and ZOOZ have been nominated for the Swedish Steel Prize 2023 for the development of a new steel flywheel design that offers increased safety, extended service life and lower life cycle costs with a 100% recyclable material.
Most prestigious steel prize in the world
The Swedish Steel Prize recognizes outstanding design, collaboration and innovation in the steel industry that contributes to a better and more sustainable world. It aims to inspire engineers, designers and inventors to further develop the unlimited potential of steel.
