Research on hydrogen energy to achieve carbon neutrality
Hydrogen energy system using renewable energy
To achieve a carbon neutral society until 2050, it is essential to introduce a large amount of renewable energy, but problems of grid stabilization and unused electricity from renewable energy will dramatically increase. Early commercialization of hydrogen energy is required as a disruptive technology for solving these problems and from the viewpoint of energy security. Our laboratory has been proceeding a research and development of hydrogen energy systems that use renewable energy to produce hydrogen which is stored and used. In addition, in order to construct a regionally distributed energy system for the future, we are focusing on a combined energy system using renewable energy + hydrogen energy + batteries, and are developing an integrated energy management system that also utilizes AI prediction technology.
High-capacity hydrogen storage materials and new hydrogen battery
Hydrogen storage alloys are a safe and stable material to store and transport hydrogen for long periods of time. These alloys can absorb and release hydrogen easily. They can safely store hydrogen at a higher density than liquid hydrogen and are already used as stationary tanks. Nickel-metal hydride batteries using these hydrogen storage alloys are used in hybrid cars and other vehicles because of their safety and high energy density. At present, the negative electrode material with the highest performance is the La-Mg-Ni super-lattice alloy that has been developed, but research on ternary hydrogen storage alloys and the development of a new type of hydrogen storage battery are underway to achieve even higher performance.

La-Mg-Ni super lattice alloy for hydrogen storage
It's been more than 35 years since I started researching hydrogen energy in the late 1980s. I am absolutely certain that hydrogen has the great potential as an energy carrier. After the Tohoku earthquake in 2011, I have been working on new energy systems that combine renewable energy power supply and hydrogen storage to change the current situation where we rely on thermal power generation. We are aiming for an early demonstration of the system so that we can build a resilient society.
