Power Systems R&D Center
OVERVIEW
We are developing new technologies and products in response to technological innovations in the electric power infrastructure sector, such as widespread use of renewable energy and sophisticated power infrastructure by using infocommunications technologies. More specifically, we are conducting R&D in elemental technologies to create products, equipment and systems that are essential for smart grids, i.e. future power networks..
Redox Flow Battery
Toward stable operation of renewable energy
In power systems using renewable energy generation, secondary batteries play a critical role in power storage and discharge in response to fluctuations in generated power. Redox flow batteries are suitable for irregular, highly fluctuating charge-discharge operation, and enable accurate monitoring and control of stored power. Therefore, they show promise as the most suitable batteries for smart grids designed for efficient use of renewables such as solar and wind. Based on our previous commercial experience, we are pushing ahead with development aiming to put the batteries into full-fledged use.
Power Control System
Energy storage system for residential and industrial use
Power control systems are used for grid-connected/isolated operation of renewables including solar power as well as secondary batteries in optimum conditions. We are developing advanced power control systems employing power electronics technology. Using power control systems with solar panels and secondary batteries, we also conduct development of distributed power systems for household and industrial use.
High Temperature Thin Film Superconducting Tape
High current density and low cost using an original clad-type metal tape substrate
Our high temperature superconducting tape can carry superconducting current more than 200A with very small dimensions of 4mm in width by 0.13mm in thickness. An originally developed clad-type stainless base metal tape substrate enables low cost, low magnetism and high texturing of thin film superconductor. We anticipate it widespread adoption in cables, electromagnets, nuclear magnetic resonance (NMR) devices, magnetic resonance imaging (MRI) devices and others.
