Development of a medium-sized hydraulic excavator powered by a hydrogen fuel-cell
12/11/2024
※ This is for illustrative purpose.
Based on our medium-sized hydraulic excavator, this proof-of-concept machine is equipped with a cutting-edge hydrogen fuel cell system. The machine combines key components originally developed by Komatsu and Komatsu's total control technology to deliver powerful excavation performance and high operability equivalent to conventional engine-powered models, while achieving zero emissions and a remarkable reduction in both noise and vibration. Emitting only water and steam, this model is the cleanest Komatsu has ever developed and a big step on our journey to practical utilization of hydrogen and achievement of carbon neutrality.
