Long known for its use of hybrid technology and exploration of
electrification, Komatsu has joined the new race to determine if
hydrogen is the fuel
of the future.
The company has started proof of concept tests and is accelerating its
efforts to begin commercial production of medium- and large-sized
construction equipment powered by hydrogen fuel cells “in the near
future.”
For the new concept machine, Komatsu collaborated with Toyota Motor
Corporation in the adoption of a hydrogen fuel cell system and
hydrogen tank to fit with the company's medium hydraulic excavator.
Combining Toyota's fuel cell system with its control technology and
components, Komatsu is hoping to achieve zero exhaust emission and a
significant reduction in noise and vibration.
According to Komatsu, the excavator delivers the same performance, in
terms of digging and operability as an engine-driven machine.
To date, electrification with batteries has been directed primarily
toward compact equipment. Medium- and large-sized construction
equipment requires a power source with higher energy.
JCB, Hyundai, Volvo and
now Komatsu have been advancing hydrogen or hydrogen fuel cell
technology as an alternative electrification option for larger
machines because hydrogen has a higher energy density and can be
refueled in a shorter time. The development of the machine lines up
with Komatsu’s intent to achieve carbon neutrality at workplaces of
construction equipment.
The equipment manufacturer has committed to minimizing environmental
impact through its business, targeting a 50% reduction in CO2
emissions from the use of its products and production of its equipment
by 2030 (compared to 2010 levels) and a challenging target of
achieving carbon neutrality by 2050.
To help its customers achieve carbon neutrality, Komatsu has been
advancing research and development on a variety of products, services,
and solutions that reduce environmental impact, such as more hybrid
diesel-electric hydraulic excavators and electric mini excavators.
At ConExpo-Con/Agg 2023, Komatsu showcased a variety
of electrified machines that are on the verge of coming to market.
