Volvo CE Pushing Alternative Powertrains
EUROPE REPORT
Emiliano Marzoli Volvo Construction Equipment (Volvo CE) has started testing its prototype “HX04” Hydrogen Fuel-Cell Articulated truck. Carolina Diez Ferrer, Head of Advanced Engineering Programs at Volvo CE expects that this prototype will “give valuable insights into the opportunities of hydrogen in the energy transformation alongside battery-electric solutions.”
The on-going development of the hauler began in 2018 and experienced partnerships with different Swedish institutions and companies. Fun fact: The machine is nicknamed “Electric Charlie,” a homage to “Gravel Charlie,” the world’s first Articulated hauler produced by Volvo in 1966.
Shell has been involved in the project, supplying the Hydrogen refuelling station for Volvo’s test track. The Volvo HX04 is charged with 12 kg hydrogen in about 7.5 minutes, enabling it to operate for approximately four hours. Fuel cells work by combining hydrogen with oxygen and the resulting chemical reaction produces electricity which powers the machine.

Day 3, CONEXPO
Wacker Neuson Plate Tamper and Compactor
The batteries on these machines run 60 minutes and charge in 80 minutes, which Wacker believes is enough for a typical work day. The machines are surprisingly quiet, given the type of work they do, and they have the added benefit of not emitting fumes into deep excavations with no air flow. The shock system is sufficient that the vibrations barely reach the battery, and they’ve had no issues with vibrations affecting the batteries so far. Unlike with other…
