Komatsu has developed a concept machine for a medium-sized hydraulic excavator that combines a hydrogen fuel cell and Komatsu-developed components to achieve carbon neutrality on construction sites.

By advancing the Proof of Concept (PoC) tests that started in May 2023, Komatsu will accelerate its efforts to embark on the commercial production of medium-sized and large construction equipment powered by hydrogen fuel cells in the near future.

For the new concept machine, Komatsu adopted a hydrogen fuel cell system and hydrogen tank, which were produced by Toyota, on Komatsu's medium-sized hydraulic excavator. In addition to Komatsu's comprehensive control technology, the combination of Toyota’s hydrogen fuel cell system and Komatsu components,

Komatsu is working toward zero exhaust emissions and a reduction in noise and vibration, while delivering the same powerful digging performance and high operability as engine-driven excavators.

Medium-sized and large construction equipment requires a power source with higher energy density compared to small construction equipment, which has led the move to electrification with batteries. Because hydrogen has a higher energy density and can be refueled in a shorter time than recharging batteries, Komatsu has been supporting research and development efforts for this technology.

To contribute to realizing a hydrogen society and carbon neutrality, Komatsu will continue its efforts toward the commercial production of medium-sized and large construction machinery equipped with hydrogen fuel cells by conducting PoC tests of this new concept machine.

IRONPROS Takeaway

Hydrogen-powered construction machinery has a long way to go, as the technology is still under heavy development. Several top equipment brands, including JCB and Hyundai, have taken the lead to make hydrogen equipment a reality on jobsites.
