Obayashi Corporation, in cooperation with Komatsu, conducted a demonstration experiment of hydrogen use at construction sites. A hydrogen-mixed combustion generator was introduced to charge an electric mini-excavator used in slope repair work on the Oita Expressway, and the practicality of small electric construction machinery at construction sites was confirmed. Compared to using diesel alone as fuel, carbon dioxide (CO2) emissions during charging were reduced by approximately 40%, and the results of the demonstration will be utilized in the planned introduction of electric construction machinery (GX construction machinery) in the future. In the demonstration, Komatsu’s electric mini-excavator “PC30E-6”, which has been certified as a GX construction machinery, was used for loading […]
