Hyundai Construction Equipment is set to exhibit its HW155H hydrogen fuel cell-powered wheeled excavator concept at the Bauma exhibition in Munich. This innovative excavator is designed to showcase the potential of hydrogen in contributing to carbon-free operations on construction sites. The fuel cell technology utilized in the excavator generates electricity by reacting hydrogen with oxygen, resulting in water vapor as the only emission. This technology offers power on demand through electric motors or electrically driven hydraulic pumps. The collaboration between Hyundai Construction Equipment and Hyundai Motor Company has developed fuel cells with a combined power output of 70-100kW, suitable for various machines like excavators, forklift trucks, and emergency generators. The HW155H excavator operates using a fuel cell-powered electric motor that drives the hydraulic system, with a hydrogen storage capacity for a full eight hours of operation. The safety features of hydrogen, such as its high auto-ignition temperature and lightweight nature, make it an attractive and safe fuel option for construction projects. Hyundai's solid state storage system enhances the capacity of conventional hydrogen tanks while optimizing space, reducing refill times, and improving overall safety on construction sites.
