Mitsubishi Power achieves 30% hydrogen fuel blend demonstration

Mitsubishi Power has successfully demonstrated a 30% hydrogen fuel blend in a grid-connected class J-series Air-Cooled (JAC) gas turbine, it said on November 30. 

The demonstration was conducted at the T-Point 2 combined cycle power plant validation facility, with a rated output of 566 MW, located within the Takasago Hydrogen Park at Mitsubishi Power’s Takasago Machinery Works in Takasago City, Hyogo Prefecture, Japan.

Utilising hydrogen produced at the Takasago Hydrogen Park, this demonstration represents the world’s first power generation test on a large-frame gas turbine using a 30% hydrogen fuel blend while connected to the local power grid, Mitsubishi power said. Notably, the hydrogen used for the demonstration was both produced and stored on-site.

This project builds upon the results of a project subsidised by Japan’s New Energy and Industrial Technology Development Organization (NEDO).

Looking ahead, Mitsubishi Power plans to conduct a 100% hydrogen-firing demonstration in 2024 using a small-to-mid-sized H-25 gas turbine (40 MW class) that had been previously installed for compressor driving at the combustion test facility within the Takasago Hydrogen Park. Additionally, the company will expand the hydrogen storage facility and conduct a demonstration using a 50% hydrogen-blended fuel.
