Energy consumption has been increasing year by year due to recent progress in information and communication technology (ICT) and rapid expansion of its applicable range. Furthermore, environmental problems such as global warming caused by emission of carbon dioxide have become severe, so that it has become important to establish a so-called "eco-friendly technology". Superconducting technology is expected to be a candidate to lead to overcome both the energy and environmental problems in the near future. In the Superconductivity Application Laboratory, basic research and development (R&D) are in progress for realization of advanced superconducting large-scale devices applicable in various fields such as electric power, energy, industry, transportation, medical service, molecular structure analysis, etc. In the fields of molecular structure analysis and medical service, for example, in order to develop high temperature superconducting (HTS) magnets for nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) systems, methods to eliminate a screening-current-induced field are originally proposed and the practical research toward their realization is on-going through international patent application. In the field of electric power, a maintenance-free superconducting pump composed of superconducting motor and cryogenic magnetic bearing for long-length circulation cooling of HTS power transmission cable is also investigated under the financial support from public funding. Moreover, in the field of transportation, superconducting level sensors to measure the amount of liquid hydrogen in the container continuously are originally proposed and developed toward applications to satellite launch rocket, hydrogen vehicle, etc.
