Komatsu introduces a concept machine for a medium-sized hydraulic excavator powered by a hydrogen fuel cell.

Incorporating a hydrogen fuel cell system and hydrogen tank supplied by Toyota, Komatsu has integrated these components into their medium-sized hydraulic excavator concept machine. Leveraging Komatsu's extensive control technology alongside Toyota's hydrogen fuel cell system, this collaborative effort is aimed at achieving zero exhaust emissions and substantially diminishing noise and vibration levels. All the while, this innovative design retains the robust digging performance and exceptional operability synonymous with engine-driven excavators.

          Medium-sized and large construction equipment demand a power source with greater energy density compared to smaller counterparts, prompting a shift towards electrification using batteries. However, due to its superior energy density and quicker refueling capabilities compared to recharging batteries, hydrogen has emerged as a promising option for electrifying medium-sized and large construction equipment. Komatsu has been actively investing in research and development in this direction. In alignment with its commitment to contribute to the realization of a hydrogen-based society and achieving carbon neutrality, Komatsu will persist in its endeavors to bring medium-sized and large construction machinery equipped with hydrogen fuel cells to commercial production. This commitment includes conducting Proof of Concept (PoC) tests using the newly introduced concept machine.
