Hydrogen fuel cell technology is just one of a number of alternative energy sources. Hyundai believes it has mileage.
Hyundai’s HW155H hydrogen fuel cell powered wheeled excavator concept, which was awarded second place in the coveted Bauma 2025 Innovation Award in the Climate Protection category provides a clear direction of travel for construction machinery, says the company.
Developed in cooperation with Hyundai Motor Company, a leader in the fuel cell field, the machine is equipped with a single fuel cell that creates 90kW of electrical energy. This powers an electric motor, that in turn drives the machine’s hydraulic system.
As well as demonstrating how a hydrogen fuel cell can be used to power construction machinery, Hyundai has also unveiled a ground-breaking high-density metal hydride solid hydrogen storage system. This low-pressure storage solution provides the machine with up to 12 hours of operating autonomy and can be refuelled in a similar time to a conventional diesel tank.
Alongside the HW155H, Hyundai is also planning a hydrogen refuelling solution, based on a hydrogen fuelcell powered road going truck. Capable of refilling multiple construction machines at the same time, this mobile refueler demonstrates how the technology could be easily adopted on remote construction projects. The construction industry is facing growing pressure to reduce its environmental impact and, with the HW155H and its refuelling solution, Hyundai Construction Equipment has demonstrated the feasibility and viability of hydrogen use within its machinery, paving the way to a more sustainable future.
“To actually have the HW155H and the hydrogen refuelling truck operating on our stand at the Bauma fair was a massive attraction for visitors, while customers and dealers were fascinated to see how this emerging technology could play a vital role in the construction equipment of tomorrow,” said Peter Sebold, product manager at Hyundai.
