(Tokyo/Japan) – Mitsubishi Power Ltd., part of Mitsubishi Heavy Industries, Ltd. (MHI), wants to build a hydrogen center in Japan. The “Hydrogen Park” is being built on the site of the MHI “Takasago Machinery Works” in the industrial area of Takasago, about 50 kilometers west of Kobe on the island of Honshu. 
To date, mainly conventional gas and steam turbines have been produced there. In the future, the group will also develop and build turbines suitable for hydrogen at the site. For this purpose, Takasago Machinery Works will be gradually expanded.
A research and innovation center will be integrated into the industrial facility, which will determine and control all work and production processes from the design of the combustion chamber to the finished turbine. According to Mitsubishi Power, this development cycle in one and the same plant enables “faster and safer product development and marketing”.
Large turbine for co-firing
In order to advance the commercialization of gas turbines that can be used with hydrogen by 2025, electricity generation with a JAC class (J-series Air-Cooled) turbine will first be examined. The proportion of hydrogen for additional combustion is initially 30 percent. A conventional variant of this large turbine, which according to the company can operate at 1.650 degrees Celsius, began test operation in July 2020 in a 566 megawatt gas and steam combined cycle power plant (gas turbine combined cycle, GTCC).
According to Mitsubishi, the testing of a 100 percent hydrogen-fired system is carried out with a class H-25 gas turbine, the output of which can range from 40 to 120 megawatts, depending on the design.
Use of turquoise hydrogen
In addition, the MHI Group is setting up a hydrogen value chain on the company premises in the city of Takasago. Mitsubishi uses power to produce hydrogen 
an electrolysis system, but says it is already planning to gradually test other technologies, such as methane pyrolysis for the production of turquoise Hydrogen. Methane is broken down into the components hydrogen (H2) and carbon (C) in the absence of oxygen. Hardly any carbon dioxide (CO2) is produced during production. Granular solid carbon is a raw material that the chemical industry, among others, processes in its process chains.
Mitsubishi Heavy Industries (MHI) is one of the world's leading industrial groups in the areas of energy, logistics and infrastructure, industrial machinery, aerospace and defense. The subsidiary Mitsubishi Power develops and produces, among other things, gas turbines, solid oxide fuel cells (SOFC) and air quality control systems (AQCS).

Together with our partners, we are a global leader in the field of pulse tunneling photocatalysis (PC.X).
This allows, among other things, H2O to be split into H2 and O2 using only process waste heat and with much cheaper plant technology, and for over 8,000 hours per year, many times more efficiently than with electrolysis.
For example, H2 and O2 can be generated directly on-site and without logistics next to an H2 and O2 steam turbine and fed into the turbine. The exhaust steam is then immediately recycled to the PC.X fission reactor as high-quality recycling, and these two gases are immediately transferred back to the gas turbine via the shortest possible route.
This brings groundbreaking advantages for the decentralized generation of electrical energy and the production of propulsion power for aircraft, trains, ships, buses, trucks, and cars.
We are pleased to cooperate with Mitsubishi Power and others in the areas of R&D, production, and commercialization of these innovative technologies.
Dear Peter, thank you very much for your comment and the insights into your innovative technology! I wish you and your partners continued success in the development and implementation of your projects. It's great to see such innovations driving sustainable and decentralized energy production forward!
Best Regards,
Ralf
