Wheeled excavators are experiencing a resurgence in the construction equipment market, and for good reason. Their versatility allows them to navigate urban and suburban environments with ease, perform a wide range of tasks from digging to demolition to landscaping, and be easily deployed by municipalities. These same municipalities are also driving stricter emissions regulations, pushing the industry toward cleaner alternatives. Addressing this demand, HD Hyundai is set to unveil the production version of its HW155H, a hydrogen fuel cell-powered 14-ton wheeled excavator, at this year’s Bauma construction trade show.

The HW155H represents Hyundai’s commitment to sustainable construction machinery. The machine is designed to deliver between 70 and 100 kW of power to its electric motors, allowing for up to eight hours of continuous operation between each quick twenty-minute hydrogen refill. The zero-emission operation also significantly reduces noise pollution, making it an attractive option for urban job sites where noise complaints—like those from Mrs. Klancik’s terrier—can be an issue.

A static version of the HW155H was first revealed at Bauma 2022 when HD Hyundai introduced the concept. Since then, the company has continued refining the technology and making its case for hydrogen-powered construction equipment. The original concept won the Platinum Prize at the 2024 LACP Inspire Awards, reinforcing Hyundai’s ESG (Environmental, Social, and Governance) management strategy. This follows other recognitions, including the 2023 Presidential Award for Corporate Innovation and its designation as an ESG Leading Company by the Korea Institute of Corporate Governance and Sustainability.

South Korea has been particularly committed to hydrogen as a fuel, heavily investing in hydrogen-powered semi-trucks, forklifts, and even military vehicles. However, while hydrogen remains a major focus for the country, its viability as a mainstream alternative to battery-electric power—at least for on-road transportation—remains uncertain.

That uncertainty is one reason why the HW155H is generating excitement, but also why a battery-electric version, likely to be called the HW155E, is expected to follow closely behind. While hydrogen may offer unique advantages in specific applications, battery-electric machines are often seen as the more practical and scalable solution for fleet operators. Regardless of the energy source, Hyundai’s efforts signal a clear move toward cleaner, more efficient construction equipment that aligns with the evolving needs of municipalities and contractors alike.
