Hydrogen is the most abundant element in the known universe, and in a climate where the scarcity of resources is at the forefront of our minds, its value as an energy source that produces zero carbon emissions cannot be overestimated. The potential of hydrogen has caught the attention of scientists worldwide, with several candidates so far being uncovered to fulfil the role of supplying or storing hydrogen as a compressed or liquified gas. Of these candidates, metal alloys have proven to be promising options, although there is still much work to be carried out in this area in terms of operability and economic value. At Kyushu University's Department of Applied Quantum Physics, Assistant Professor Yuji Inagaki and Associate Professor Tatsuya Kawae are focused on detecting and measuring hydrogen absorption in metals. In doing so, they are also investigating fundamental properties of hydrogen-related phenomena, such as superconductivity with potential high-Tc in hydrogen-rich materials and quantum tunneling of hydrogen in metals. Their research has prompted the development of novel techniques and real-time measurement of hydrogen absorption, resulting in very real progress towards realising a world in which the metal-hydrogen system plays an essential role in reducing environmental loading.
