Epiroc says it is pioneering a battery-electric underground mine truck prototype made from fossil-free steel in line with the company’s vision to produce the world’s greenest machines.

This partnership with Swedish steelmaker SSAB, Epiroc says, accelerates the journey towards reduced carbon-dioxide emissions, ultimately helping mining companies reach their climate goals.

In partnership with steel manufacturer SSAB, Epiroc is now prototyping an underground mine truck with a dump box made of fossil-free steel, the battery-electric Minetruck MT42. The result is a 10-t reduction of CO2 emissions per manufactured dump box, the equivalent of taking five gasoline cars out of service for an entire year, Epiroc said.

The partnership will help Epiroc accelerate its journey to create a more sustainable future, deliver the world’s greenest machines and support its customers.

“Our innovation agenda goes hand in hand with our customers’ sustainability agenda,” Sami Niiranen, President of Epiroc’s Underground division, says. “In the shift to a new, low-carbon economy, our products and services will be a key contributor for our customers to meet their climate goals.”

SSAB aims to deliver fossil-free steel to the market in commercial scale during 2026, and delivered the first steel made of hydrogen-reduced iron in 2021. SSAB works with iron ore producer LKAB and energy company Vattenfall in Sweden as part of the HYBRIT initiative to develop a value chain for fossil-free iron and steel production, replacing coking coal traditionally needed for iron ore-based steelmaking, with fossil-free electricity and hydrogen. This process virtually eliminates carbon dioxide-emissions in steel production.

“The development of new technologies is essential to enable the transition to a low-carbon economy,” Johnny Sjöström, Head of SSAB Special Steels, said. “Our fossil-free steel immediately reduces the carbon footprint to near zero without compromising the high quality and properties you would expect from SSAB steels. It is the same steel, just without the negative environmental impact.”

The battery-electric Minetruck MT42 is a breakthrough for Epiroc’s sustainable innovation, the company said. It is a significant step in the company’s ambition to produce cutting-edge, environmentally smart mining equipment. It is emissions-free in operation, generating a strong positive impact on the climate as well as on operators’ work environment and productivity, according to the OEM.

“We all play a part in creating a more sustainable future,” Camilla Goldbeck-Löwe, Vice President Corporate Responsibility at Epiroc, said. “Our partnership with SSAB has enabled us to present the world’s first underground mine truck made using fossil-free steel.”
