Key Findings
Aichi Tokei Denki has moved its hydrogen gas measurement technology from the research phase to real-world implementation. The company is currently participating in the “Low-Carbon Hydrogen Model Town Demonstration Project” in Chita City, Aichi Prefecture. This project utilizes the Chita Hydrogen Station, operated by Chita High Pressure Gas, to supply renewable energy-derived low-carbon hydrogen to business sites, public facilities, and residential homes.
Technical Details
The technical objective is to accurately monitor the real-time flow rate of hydrogen gas, which is essential for safety, facility management, and fair commercial transactions. Because hydrogen possesses physical and flow characteristics distinct from natural gas, Aichi Tokei Denki developed specialized measurement technology through technical validations with energy providers, research institutions, and universities. Key R&D focus areas include:
- Advancing hydrogen gas flow measurement technology.
- Conducting measurement evaluations in pure hydrogen and hydrogen co-firing environments.
- Verifying safety and reliability for hydrogen supply infrastructure.
- Utilizing ultrasound for measuring hydrogen flow.
Background and Context
This initiative aligns with Aichi Tokei Denki’s Mid-Term Management Plan 2026, which emphasizes contributing to a sustainable society through measurement and connectivity technologies. The company is leveraging its existing expertise in fluid measurement for water, gas, and thermal energy to address the specific requirements of a decarbonized society. The Chita City project serves as a testing ground to verify how these technologies function in actual living environments and community settings.
Significance and Outlook
The integration of accurate measurement technology is presented as a foundational requirement for the “produce, transport, and use” cycle of a hydrogen society. By applying hydrogen to fuel cells and hydrogen water heaters within a model town, the project seeks to reduce the costs of hydrogen supply networks. The goal is to establish a scalable model for low-carbon hydrogen utilization that can be deployed nationwide to help achieve carbon neutrality by 2050.
