Recently, Kawasaki Heavy Industries of Japan and Kobe Steel jointly announced that the world’s first next-generation hydrogen-fueled power generation system for hydrogen-based power generation had officially commenced operation. The system features a liquid hydrogen energy supply model and is designed to provide stable power for future large gas turbine generators, filling the global technological gap in direct liquid hydrogen supply for power generation.
The newly commissioned system was developed under the NEDO-funded project in Japan, “Development of Technologies to Improve Hydrogen-Fueled Power Generation Efficiency and Performance Under the Hydrogen CGS Regional Model,” and was deployed at the Kobe Hydrogen Energy Center on Port Island in Kobe. It is the world’s first hydrogen supply power generation system to adopt an intermediate fluid vaporizer (IFV) for hydrogen together with a liquid hydrogen pump, enabling liquid hydrogen to be pressurized above critical pressure and directly supplying hydrogen fuel to power plants in a stable manner.
The project had a clear division of responsibilities: Kawasaki Heavy Industries was responsible for optimizing the liquid hydrogen pressurization fuel supply system for gas turbine generators, while Kobe Steel focused on the R&D of IFV equipment utilizing the cold energy of liquid hydrogen. At present, demonstration tests have successfully delivered hydrogen fuel to a wet gas turbine, and subsequent hydrogen supply tests for a dry gas turbine will be carried out, with a focus on verifying operating performance under high summer temperature conditions as well as the long-term operational reliability of the liquid hydrogen pump.
