Hydrogen storage for future hydrogen society

Akito Takasaki

Hydrogen is now stored as gas phase in high pressure cylinders, whose volumetric and gravimetric capacities are quite low. Alternative method to store hydrogen is to store it as liquid form, but it requires low temperatures. Recently, hydrogen storage in solid materials has attracted a great attention because of high volumetric capacity and safety. After discovery of an Al-based quasicrystal alloys in 1984, we have been working for hydrogen storage in Ti-based quasicrystals to investigate the total hydrogen performance, because of their unique structures. On the other hand, magnesium hydride (MgH2) is one of the most promising candidates for hydrogen storage materials, due to its high hydrogen storage capacity with a theoretical value of 7.6 wt.%. However, the practical use of MgH2 for hydrogen storage is limited, due to its high thermodynamic stability and slow hydrogen kinetics. In our laboratory, we also work for MgH2 to improve its total hydrogen performance after doping some catalysts. Instead of these hydrogen storage materials, we also work for electrochemical hydrogenation for some alloys, production of shape memory alloys, oxygen storage materials and thin metallic films, and novel industrial application of biomass.

Through the research and development of a robot as an intelligent mechanical system, we will create the new concept of the robot and its realization, and we will develop technologies contribute to the society by improving the mechanical system around us more intelligent using robot technologies.
It is very important how to design the concept of the robot system, and we should think the system as a human centric robotics because robots are always support human beings.
Although the market of the robot now is not so big, we expect the robot will be inevitable in the society with decreasing birth rate and increasing elderly. We will research the robot with an objective of the system clearly.
