BREAKING NEWS: Komatsu develops excavator with hydrogen fuel cell system
Komatsu has just unveiled a literally ground-breaking concept machine. Ready to begin proof-of concept testing, the newly developed excavator concept mates a Toyota hydrogen fuel cell system with the latest comprehensive control and performance technology from Komatsu.
Hydrogen has high energy density and can be refueled in a shorter time than recharging batteries, an attractive choice for “carbon neutrality”- conscious customers.
“Innovative operability, co-creation with pioneering technology, sustainability with no sacrifice to performance – this concept machine is a concrete step on Komatsu’s road to creating a future where we all thrive together,” the company said.
For the new concept machine, Komatsu adopted a hydrogen fuel cell system and hydrogen tank, which were produced by Toyota Motor Corporation, 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 requires a power source with higher energy density than that of small construction equipment, which has led the move to electrification with batteries.
Because hydrogen can be refueled in a shorter time than recharging batteries, Komatsu has been advancing its R&D efforts as a promising electrification choice for medium-sized and large models.
