Komatsu advances hydrogen fuel cell technology for medium-sized Construction Equipment

To attain its sustainable goals, Komatsu has developed a concept machine for a medium-sized Hydraulic Excavator that combines a hydrogen fuel cell and Komatsu-developed vital components to achieve carbon neutrality at Construction Equipment workplaces. By advancing the Proof of Concept (PoC) tests it 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.

Carbon Conquest

Komatsu is steadfast in its commitment to minimising environmental impact through its business. They are targeting a 50% reduction in CO2 emissions from the use of our products and production of our equipment by 2030 (compared to 2010 levels) and a challenging target of achieving carbon neutrality by 2050. To help their Customers achieve carbon neutrality, they have provided various products, services and solutions that reduce environmental impact. Komatsu is also engaged in research and development to provide products equipped with new power sources, demonstrating our unwavering dedication to a sustainable future.

For the new concept machine, Komatsu adopted a hydrogen fuel cell system and hydrogen tank, 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 key components, Komatsu is working toward zero exhaust emissions and a significant 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 require a power source with higher energy density than small Construction Equipment, which has led to electrification with batteries. Because hydrogen has a higher energy density and can be refuelled faster than recharging batteries, Komatsu has been advancing its R&D efforts as a promising electrification choice for medium-sized and large models. To contribute to realising 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.
