Abstract
This study focuses on comparing the life-cycle energy required for Conventional Steel and HYBRIT (Hydrogen Breakthrough Ironmaking Technology) Steel. The application chosen for this comparison was a bogie beam of Volvo’s articulated hauler A30. HYBRIT is a new generation of a fossil-free steel technology developed by SSAB (Swedish Steel Company) which aims to replace coal with hydrogen during steel production to reduce CO2 emissions. The different phases analysed where; material extraction, steel production, component manufacturing, use and end of life phases. Where the use phase is predominantly fatigue loading. It is concluded that HYBRIT Steel consumed 8-10% less energy than Conventional Steel over the entire lifecycle. For applications with less dominant use phases, the percentage of energy saved by HYBRIT Steel would be even larger.
