Game-Changing Technology Area

“Game-Changing Technology Area” were newly established at the same time as the Enabling Technology project and were launched in fiscal 2015. Promising issues not ready for transfer to the Enabling Technology project will be incubated in these “Game-Changing Technology Area”. The projects were currently promoted with 19 issues in fiscal 2017.

G1 Solar Cell and Solar Energy Systems

Solar energy use, including solar cells, has already prevailed in the society as one of the extremely promising technologies for renewable energy. Competing with the commercial Si-based solar cell module technologies, we wish to further develop the solar cell and solar energy utilizing system which are addressed in ALCA.
Specifically, the project is to be subjected for development of the solar cell with high energy conversion efficiency (compared with the conventional solar cell), production of new materials for solar cells, creation of manufacturing process of low cost solar cells such as large surface manufacturing technology, and development of a solar energy utilizing system integrated with these technologies. Especially, we are going to promote the research and development in perovskite solar cells, which were first reported by Miyasaka et al. in Japan and have been addressed in the ALCA Tech. Area. In addition, we also aim to develop other innovative solar thermal energy technology.

“Superconducting systems,” which utilize the zero electrical resistance of superconductors, represent an area of technology in which substantial energy savings can bring about decreased carbon emission in a wide range of fields including electric power, transportation, industries, and computing.
In the field of electric power, for example, research and development of technologies including on superconductive power generators, superconductive electrical cables, and superconductive energy storage units, is being carried out. Superconductive instrument systems including cooling systems may be realized in the future, which would result in great changes to conventional electric device systems. Superconductive motors and magnets, combined with various advanced elemental technologies, may also be able to greatly improve the efficiency of energy devices.

Fellow, National Institute for Materials Science

It is requested to further spread Electric Vehicles (EVs) and renewable energy generation for reducing GHG emission. For example, in order to improve the cruising distance of EVs, the electricity storage device has to provide both higher energy density and higher power. In addition, as the power generation based on the renewable energy increases, the stationary electricity storage devices become more necessary for stabilizing the short-term fluctuation load in the electricity system. In this ALCA Tech. Area, we are promoting the R&D for the innovative electricity storage device as the key technologies.

Emeritus Researcher, National Institute for Materials Science

Decreasing the carbon dioxide emissions of the power generation, metal, and transportation industries, which emit large quantities of greenhouse gas, is an urgent issue for achieving a low carbon society. Carbon dioxide emissions must be decreased through improved energy efficiency by improving the performance of heat-resistant materials that are used for power generation turbines, jet engines for airplanes, and other applications. To achieve this, ALCA aims to develop technologies to substantially improve the properties of these materials, such as their high-temperature strength, room-temperature resilience, oxidation resistance, as well as technologies for their production and heat-resistant coating.
In addition, other research subjects include establishing manufacturing technologies for high-strength and high-performance materials from recycled raw materials, in order decrease the energy consumption of recycling, and the creation of structure-control to realize high performance while decreasing the amount of rare metals to be added.
Furthermore, ALCA will develop innovative metal and ceramic materials for the manufacture of lighter and stronger materials, in order to produce lighter transportation equipment that consumes less energy.
