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.
