Power Conversion
The effective utilization of renewable energy and the conversion of CO₂ into useful resources are essential for achieving carbon neutrality. We are researching technologies such as Power to Gas (P2G), which uses water electrolysis to convert weather-dependent renewable energy into hydrogen that can be stored and transported, and Power to Chemicals (P2C), which breaks down CO₂ to produce synthetic fuels and other compounds.
In the P2G domain, we are working on proton exchange membrane water electrolysis using solid polymer electrolytes, which offer excellent adaptability to fluctuating renewable energy inputs and high durability. We have established large-scale electrode manufacturing technology that reduces the use of rare iridium by 90%. We are also developing a hydrogen production process based on high-temperature steam electrolysis that uses proprietary oxide electrode materials.
In the P2C domain, we have developed a CO₂ electrolysis cell stack featuring proprietary catalytic electrodes that can process CO₂ at high speed.
Digital Transformation for Field Work Support
By utilizing positioning technology that improves the efficiency of patrol inspections and record management, we automate and streamline part of patrol inspection operations, contributing to the resolution of social issues such as labor shortages.
