One of the challenge to realize hydrogen combustion in gas turbines is its fast combustion speed that may cause flashback; firing backwards against fuel supply. Mitsubishi Power’s gas turbines have a proven track record of firing a wide variety of fuels, including hydrogen-rich fuels, and the company is fully aware of the challenges with hydrogen-firing. We will convert the demonstration facilities, called T-Point 2 located at the Mitsubishi Power Takasago Machinery Works, into the Takasago Hydrogen Park. In the new facility, validation of hydrogen combustion at the grid-connected environment prior to product introduction will be conducted. It will enable us to identify risks or problems in advance and make improvements before delivering the product to our customers. The validation results will be immediately shared with the R&D, design, and manufacturing departments located at the same site so that improvements can promptly be applied to actual products. Mitsubishi Power will continue to demonstrate its high reliability through these sequences, and this approach will be also taken now in hydrogen-fired systems.

Mitsubishi Power already offers 100% hydrogen-fired with diffusion combustors for H-25 gas turbines. Meanwhile, a high-performance multi-cluster combustor, which has lower NOx emissions than the diffusion combustors, will be installed in an actual H-25 gas turbine at Takasago Hydrogen Park. 100% hydrogen-fired validation test will be completed in 2024. Using this unique approach of validation of the first unit at one’s own manufacturing location, Mitsubishi Power provides high reliability to future installation at customers plants.
