Hitachi Energy selected for mining electrification project17 May 2022

Hitachi Energy has been selected as a technology vendor in the Charge On Innovation Challenge. Founded by BHP, Rio Tinto and Vale, together with multiple industry patrons, the initiative sees the world’s mining industry unite to solve one of the biggest challenges in decarbonizing mining operations: the electrification of haul trucks.

Hitachi Energy put forward an innovative proposal which met with the judges’ rigorous criteria for interoperable solutions. The flexible solution design enables electricity to be safely delivered to large battery-powered off-road electric haul trucks, while maintaining or improving productivity levels. The end-to-end solution connects the mine’s electrical grid directly to its haul trucks and other vehicles, such as excavators.

Advanced power electronics and digital technologies are key to the design of Hitachi Energy’s innovative solution to electrify the haul trucks which are used to transport materials. At the heart of the design is Grid-eMotion Flash – a pioneering solution for sustainable e-mobility, enabling the haul trucks’ batteries to be rapidly and safely recharged in just a few minutes.

To further optimize energy use across the mine, Hitachi Energy is also able to deliver a full solution, including its innovative e-mesh™ digital solutions for e-mobility. Additionally, a holistic and detailed monitoring and control solution for the charging process and the grid connection system. A range of remote and onsite services will also be made available to support the transition to the new technologies and the efficient operation of the new infrastructure.

Gerhard Salge, CTO of Hitachi Energy said, “The Charge On Innovation Challenge is another great example of how we are collaborating with whole industries to accelerate the energy transition towards a carbon-neutral future.” He continued, “Hitachi Energy’s proposal is for an innovative haul truck 24/7 electrification solution that will help the world’s mining industry to decarbonize without compromising on productivity. Electricity will be the backbone of the entire energy system and together with customers and partners, Hitachi Energy is pioneering technologies and software for advancing a sustainable energy future for all.”

The system delivering 8 MW of power to enable vehicles to be charged in just a few minutes in a safe way at the points of loading and unloading. Flash charging means trucks can operate 24/7.

The interoperable, flexible Energy Transfer System (ETS) is free of any catenary infrastructure.

It also includes dynamic energy management to increase reliability, resiliency and power quality.
