Boost in the energy transition: project aims to electrify heavy construction machinery.

Danfoss Scotland, a key arm of Danfoss Power Solutions and a leader in hydraulic and electrical transmission systems, celebrates securing a generous £4,9 million grant from the Department of Energy Security & Zero Emissions. This investment, coming from the subsequent stage of the UK Red Diesel Transition Programme, will support the validation of Danfoss' innovative Dextreme Max system on a robust 30 tonne electric excavator.

Transforming the construction sector

The challenges of electrification in the sector are evident: the high energy demands of excavators require expensive batteries and bulky charging infrastructure. “Overcoming this financial hurdle is critical to the widespread adoption of electrical equipment,” says Leif Bruhn, digital mind at Danfoss Power Solutions. It highlights the importance of improving the energy efficiency of excavators, thereby reducing the need for bulky batteries and energy consumption, facilitating the transition to clean sources.

Danfoss' flagship Dextreme Max promises an energy revolution by cutting excavators' energy consumption in half. This feat is achieved by minimizing energy losses and reusing previously wasted energy. A vital aspect of this system is the DDP1x0D hydraulic pump, which captures energy from the excavator's movements, optimizing its performance and contributing to sustainability.

Towards the electric future

Looking ahead to 2024, Danfoss has ambitious plans to convert an electric excavator at its Development Center in Nordborg, Denmark. This machine will later be put to the test in a mine in the United Kingdom, with results expected by February 2025.

The project aims to demonstrate that, through Dextreme Max, it is possible:

  • Reduce battery capacity needs;
  • Lighten the load on charging infrastructure;
  • Cut operating and capital costs compared to conventional electrical equipment;
  • Offer better total cost efficiency than diesel machines;
  • Maintain or even improve productivity and durability compared to traditional equipment.

Jeff Herrin, strategic voice for Danfoss Power Solutions, expresses his gratitude for government support and highlights the company's mission to promote innovation and support its customers on the green path.

The Red Diesel subsidy initiative is just one component of the UK's wider effort to combat climate change through the Zero Emissions Innovation Project Portfolio. Danfoss, which had already received a previous grant, is committed to covering the remainder of the project costs.

For green innovation enthusiasts, the Danfoss Dextreme promises to be the future of energy efficiency in the construction sector.
