May 2023，Komatsu Co., Ltd (Hereinafter referred to as“Komatsu”) Launched a program toHydrogen fuel cellDemonstration of a medium hydraulic excavator concept vehicle as a power(PoC)。

▲Medium Hydraulic Excavator Concept with Hydrogen Fuel Cell

Komatsu proposed in its medium-term business plan that by 2030, production links and product use links will be produced.CO₂Emissions are reduced by 50% (Compared to 2010)Business objectives，And proposed a challenging goal of achieving carbon neutrality by 2050.。For the purpose of contributing to carbon neutrality for our customers，Komatsu has long been committed to providing users with hybrid hydraulic excavators.、Diversified products such as battery-powered mini-excavators that help reduce environmental load、Service、Solution，And to provide a variety of new power plant products as the goal to actively carry out related research and development work.。

The concept vehicle for this demonstration experiment is based on the medium-sized hydraulic excavator of Komatsu.，By employing a hydrogen fuel cell system manufactured by Toyota Motor Corporation、Hydrogen storage tank and core components and total control technology independently developed by Komatsu.，In the realization “Zero emission”While significantly reducing noise and vibration，It has the same powerful excavation performance and high operability as the excavator driven by fuel engine.。

Compared with the small construction machinery which has taken the lead in electrification.，Large and medium-sized construction machinery has higher requirements for high energy density power source.。Compared with the battery widely used in small construction machinery,，Hydrogen has a higher energy density.，And the filling of the hydrogen fuel can be completed in a shorter time than the charging of the battery.，Therefore, it is considered to be an effective option for the power source of medium and large construction machinery.。The goal is to realize the mass production of hydrogen fuel cell large and medium-sized construction machinery in the near future.，Relevant work is accelerating.。

Komatsu Approves Medium-Term Business Plan“DANTOTSU Value–Together, to ‘The Next’ for sustainable growth”The value of the advantages presented in (DANTOTSU Value，That is, through revenue improvement andESGThe virtuous circle of problem solving realizes the creation of customer value.)，Continue to take new steps towards the realization of the future site.，Strive to pass on a sustainable future to the next generation。
