Komatsu has commenced proof-of-concept tests at its Ibaraki plant in Hitachinaka City, Japan, of its HD785 large dump truck equipped with a hydrogen combustion engine.
Through these tests, the company aims to accumulate knowledge on hydrogen engine utilization, laying the foundation for future development of “hydrogen-powered construction and mining equipment.”
The concept machine is equipped with a hydrogen combustion engine and hydrogen tank system, which are co-developed by Komatsu and German startup company KEYOU. The hydrogen tank is mounted on a platform beside the operator’s cab to maximize hydrogen storage capacity. Additionally, to ensure clear visibility for the operator, cameras and monitors have been newly installed both inside and outside the cab.
The proof-of-concept tests will focus on evaluating driving performance, continuous operating hours, fuel efficiency, and verifying safety measures related to high-pressure hydrogen gas usage.
Under its mid-term management plan, Komatsu has set the goal of reducing CO2 emissions by 50% from its products in use and in production operations, each by 2030 (compared to 2010 levels), with the challenging target of achieving carbon neutrality by 2050.
