Mitsubishi Power’s Takasago Hydrogen Park Begins Full-Scale Production

Published on: 

Electrolysis hydrogen production has entered full swing at the integrated hydrogen validation facility in the Hyogo Prefecture, Japan.

Mitsubishi Power announced Takasago Hydrogen Park, located at Mitsubishi Heavy Industries’ (MHI) Takasago Machinery Works, began full-scale commercial operation. Electrolysis hydrogen production will bolster product reliability through hydrogen co-firing and hydrogen-operated gas turbines and expand its offerings with the introduction of hydrogen production technologies.

The validation of hydrogen-fueled equipment will be conducted at the T-Point 2 combined-cycle power plant facility using a Mitsubishi Power J-series air-cooled (JAC) gas turbine (450 MW class) and small-to-mid-sized H-25 gas turbines (40 MW class). Hydrogen produced at Takasago Hydrogen Park will be used for the validation of 30% hydrogen co-firing at T-Point 2 and is slated for completion by the end of the year. Hydrogen firing at 100% for the H-25 gas turbine will be validated in 2024.


Takasago Hydrogen Park is separated into sections based on the following hydrogen-related functions: hydrogen production, storage, and utilization. The production area is headed by HydrogenPro AS of Norway, manufacturing alkaline electrolyzers with a hydrogen production capacity of 1,100Nm3/h. Processed hydrogen will be stored in equipment with a total capacity of 39,000 Nm3.

Mitsubishi Power is developing hydrogen production technologies such as solid oxide electrolysis cells, anion exchange membrane water electrolyzers, and turquoise-hydrogen production that generates zero CO2 emissions through the pyrolysis of methane into hydrogen and solid carbon. Mitsubishi will conduct verification and validation of these technologies in sequential order. Following the development of these electrolysis technologies at the Nagasaki Carbon Neutral Park, the company intends on validating the hydrogen production of these technologies at Takasago to prepare for commercialization.
