Environment & Energy

Redox flow batteries are well-suited for irregular and highly variable charge/discharge operations. They enable precise monitoring and control of stored energy, making them an ideal energy storage solution for smart grids aiming to effectively utilize renewable energy sources such as solar and wind power. As a key technology for achieving carbon neutrality, we are advancing the development of redox flow batteries toward full-scale commercialization, building on our proven track record in the market.

MCH Electrochemical Synthesis

We are supporting the development of the Direct MCH™ Electrochemical Synthesis technology led by ENEOS Corporation, by providing our electrochemical cell technology cultivated through redox flow battery development. In addition, we are contributing to megawatt-scale demonstration testing to help enable the large-scale production of MCH (methylcyclohexane), a hydrogen carrier—advancing efforts toward a future hydrogen-based society.

Anion Exchange Membrane (AEM)-Type Water Electrolysis Cell Stack

We are developing anion exchange membrane (AEM) water electrolysis systems that do not rely on scarce precious metals and offer cost-effective hydrogen production. Since AEM systems share strong technical affinity with redox flow batteries, we are applying our advanced cell stack technology cultivated through redox flow battery development to create high-performance and highly reliable water electrolysis systems, contributing to the realization of a green society.

Leveraging our advanced expertise in insulation materials, we  are developing a wide range of power cable products, for example, ultra-high-voltage direct current (UHVDC) cables for grid interconnections and submarine cables for offshore wind power generation.
We also apply cutting-edge analysis and simulation technologies to develop production  technologies suitable for our new insulation materials and perform dynamic analysis of submarine cables, aiming to deliver high-quality, next-generation power cables.

We are developing cost-effective, rare-earth-based high-temperature superconducting (HTS) wires using our proprietary solution deposition and pyrolysis process. These wires can carry more than 200 times the current of conventional copper wires at –196°C (the temperature of liquid nitrogen). We have also achieved the world’s first stable superconducting joint technology, enabling persistent current magnets. These innovations are expected to accelerate the adoption of HTS wires in applications such as nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI), compact fusion reactor magnets, and superconducting motors.
