Mitsubishi Power Executes 30% Hydrogen-Fuel Blend in JAC Gas Turbine

Mitsubishi Power conducted a successful power generation test using a 30% hydrogen-natural gas blend at partial and full load in a 1,650ºC J-series air-cooled (JAC) gas turbine. The demonstration took place at the T-Point 2 combined-cycle power plant validation facility within Takasago Hydrogen Park (THP). Fueled with hydrogen produced at THP, the large-frame gas turbine was connected to the local power grid and operated with a 30% hydrogen fuel mix to assess the technology’s potential integration at scale.

The test demonstrated low NOx emissions, stable combustion during hydrogen co-firing, and the ability to switch from natural gas to hydrogen fuel blending during partial-load and full-load operation. In 2024, Mitsubishi Power will perform a 100% hydrogen-firing test with a small to mid-size 40 MW H-25 gas turbine that had been installed to drive compressor operation at the park’s test facility. In addition to a 100% hydrogen test, the company plans to expand the hydrogen storage facility and conduct a demonstration using a 50% hydrogen blend.

"We see Takasago Hydrogen Park making a contribution to the implementation of hydrogen power generation through improvements in product reliability based on verifications and accelerated commercialization,” said Mr. Takashi Tozawa, Senior Fellow, Senior General Manager, GTCC Business Division of Energy Systems at MHI. “The 30% hydrogen co-firing demonstration with the JAC gas turbine is a significant milestone toward the energy transition, and we are proud that MHI is able to play such an important role."

Mitsubishi Power will continue to utilize the Takasago Hydrogen Park to advance the development and validation of hydrogen production and power generation technologies.
