Ulsan Demonstration Tests Hydrogen Fuel-Cell Excavators on Real Construction Sites
Have you ever wondered why the biggest machines on a construction site still chug along on diesel when there are zero-emission options available? Well, things are changing! In Ulsan, a bustling city in South Korea known for its shipyards and petrochemical plants, an exciting chapter in hydrogen fuel cell news is starting to unfold. A partnership spearheaded by HD Hyundai Construction Equipment has rolled out the HW155H, a 14-ton excavator powered by a 90 kW fuel cell right onto active job sites. This machine stores hydrogen in its counterweight using some pretty innovative solid-state metal alloys, allowing it to run for about 12 hours on a single fill-up and refuel in just over ten minutes. If it delivers on its promises, this could really shake things up for hydrogen infrastructure in heavy machinery.
