Hyundai Construction Equipment is set to showcase its innovative HW155H hydrogen fuel cell-powered wheeled excavator at Bauma 2024 in Munich. This working demonstration marks a significant advancement from its initial static display in 2022, highlighting the practical application of hydrogen technology in construction.
Key Features of the HW155H Hydrogen Excavator
The HW155H, a 15-tonne wheeled excavator, incorporates several groundbreaking features:
- Dual fuel cell system delivering 70-100kW of power
- 8-hour operational capacity on a single hydrogen fill
- 10-20 minute refueling time
- High-density, solid state storage system
- Versatile on-road and off-road capabilities
- Electric motor-driven hydraulic system
Advanced Hydrogen Fuel Cell Technology
Hyundai’s groundbreaking collaboration between its Construction Equipment and Motor Company divisions has yielded significant technological advances in fuel cell development. The partnership has produced two distinct fuel cells: a 30kW power unit and a 50kW power unit. These innovative cells work in tandem to deliver reliable power across multiple applications in the construction and industrial sectors. The technology has been successfully implemented in 15-tonne wheeled excavators, forklift trucks, and emergency generators, demonstrating its versatility and practical applications in heavy-duty equipment.
