Tokyo, June 23, 2026 – Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. (MHIET), a part of Mitsubishi Heavy Industries (MHI) Group, previously achieved rated operation (435kW\/1,500min-1) of a 500kW-class hydrogen engine generator set(Note1) at its demonstration facility using 100% hydrogen fuel. Recently, the company has established operational capabilities and completed reliability verification for commercialization, indicating that the generator set has reached a level of technological maturity suitable to support practical applications. MHIET will further accumulate operating hours and conduct tests to accelerate the process toward full commercialization.<\/p>\n

The demonstration tests were conducted at its Sagamihara Plant. Through more than 100 hours of operation, the following have been completed to support practical application.<\/p>\n

    \n
  1. Year-round operation was conducted to evaluate performance under various atmospheric conditions, including electrical output, generation efficiency, and emissions performance.<\/li>\n
  2. Operation strategies were established for abnormal combustion, a major challenge due to the characteristics of hydrogen.(Note2)<\/li>\n
  3. Using the prototype generator set representative of a near-commercial product, the ability to handle sudden fluctuations in power demand that may occur during actual operation was verified.<\/li>\n
  4. Various measurements including engine vibration and combustion chamber temperature were taken to confirm that there are no issues with reliability.<\/li>\n
  5. The process from receipt of green hydrogen produced in Yamanashi Prefecture(Note3) at the Sagamihara Plant to using it for power generation was confirmed.<\/li>\n<\/ol>\n

    With these achievements, all evaluations have been…<\/p>\n
