Komatsu Ltd. has initiated proof-of-concept tests for the world’s first large dump truck equipped with a hydrogen combustion engine at its Ibaraki Plant in Hitachinaka City, Japan. This innovative move aims to accumulate knowledge on hydrogen engine utilization for future development in construction and mining equipment. The hydrogen engine and tank system were developed in collaboration with German startup KEYOU GmbH, allowing for a cost-effective solution with minimal CO2 emissions. The concept machine boasts features like a hydrogen tank system beside the operator’s cab and enhanced visibility through newly installed cameras and monitors. The ongoing tests will assess driving performance, operating hours, fuel efficiency, and safety measures related to high-pressure hydrogen gas usage. Despite challenges in safety management and hydrogen infrastructure, the adoption of hydrogen combustion engines offers advantages such as cost-effectiveness and environmental friendliness. Komatsu's strategic focus on hydrogen engines aligns with its ambitious goal of reducing CO2 emissions by 50% by 2030 and achieving carbon neutrality by 2050. Through collaborations with industry stakeholders, Komatsu aims to address obstacles and promote the adoption of hydrogen engines in the construction and mining sectors, contributing to a more sustainable future.
