Komatsu has begun concept testing for its first hydrogen-powered dump truck. This vehicle will use a hydrogen combustion engine to reduce carbon dioxide emissions in the mining industry.
The first hydrogen dump truck
The concept model, based on the HD785 truck , has a load capacity of 92 metric tons and was developed in collaboration with the German company KEYOU , a specialist in hydrogen engines . Unlike other technologies such as batteries or fuel cells, this engine allows the reuse of many of the components of diesel trucks, minimizing production costs.
The tests are being conducted at Komatsu’s Ibaraki Plant in Japan, focusing on evaluating the fuel efficiency, operational performance, and safety of high-pressure hydrogen. This initiative is part of the company’s plan to reduce CO₂ emissions from its products and processes by 50% by 2030, with the ultimate goal of achieving carbon neutrality by 2050.
Interest in hydrogen combustion engines has increased in the mining industry due to their economic and operational advantages. Unlike electric systems, this technology requires no changes to existing infrastructure and provides extended operating range.
Despite the benefits, the adoption of hydrogen in heavy machinery continues to face challenges such as the availability of fueling infrastructure and safe operation. Therefore, the company is working with industry associations and experts in the field to overcome these challenges and accelerate the implementation of this energy alternative.
