Electric Site Research Project

The world’s first ‘free emission’ quarry

Volvo CE and its customer Skanska are turning the quarrying industry upside down in a groundbreaking study to create the world’s first ‘emission-free’ quarry. Drawing on the electromobility and automation expertise of the Volvo Group, the research project, dubbed Electric Site, aims to electrify each transport stage in a quarry – from excavation to primary crushing, and transport to secondary crushing – although a negligible amount of diesel power will still be used. The system’s efficiency, safety and environmental benefits are set to impact both customers and society at large.

RESEARCH PROJECT

The electric site is part of Concept Labs. Volvo CE teamed up with its customer Skanska Sweden, the Swedish Energy Agency and two Swedish universities – Linköping University and Mälardalen University – in October 2015 to collaborate on the SEK 203 million project.

Volvo CE is coordinating the project and is in charge of developing the machines and systems. Skanska Sweden is providing logistical solutions, application relevance and job site knowledge. The Swedish Energy Agency is helping to fund the project and the universities are carrying out research. Two PhD students are looking at battery aging and energy management for electric vehicles, as well as functional safety.

Testing

Volvo CE and Skanska are testing the viability of its Electric Site concept at Skanska’s Vikan Kross quarry, near Gothenburg, Sweden. The system, which incorporates electric and autonomous Volvo machines, will run in a real production environment for 10 weeks – delivering an anticipated up to 95% reduction in carbon emissions and up to 25% reduction in total cost of operations.

Concept machines

HX2

Eight small prototype HX2 autonomous, battery-electric load carriers will be transporting the material from the primary mobile crusher up to the secondary static crusher.
