Komatsu develops concept hydraulic excavator with hydrogen fuel cell system

KOMATSU has developed a new concept hydraulic excavator described as combining a hydrogen fuel cell and Komatsu-developed key components.

By advancing the PoC (Proof of Concept) tests it started in May 2023, the manufacturer revealed it has accelerated efforts to embark on the commercial production of medium-sized and large construction equipment powered by hydrogen fuel cells in the near future.

Komatsu is targeting a 50% reduction in CO2 emissions from use of its products and production of its equipment by 2030 (compared to 2010 levels) and a challenge target of achieving carbon neutrality by 2050.

To help customers achieve carbon neutrality, the business has been providing a variety of solutions that reduce environmental impact, such as hybrid hydraulic excavators and electric mini-diggers. Komatsu is also engaged in research and development to provide products equipped with new power sources.

For the new concept machine, Komatsu adopted a hydrogen fuel cell system and hydrogen tank, produced by Toyota Motor Corporation on Komatsu’s medium-sized hydraulic excavator.
