High Sensitivity Hydrogen Selective Sensor Module - Hydlog20

The realization of odorless hydrogen supply through pipelines, assuming large-scale hydrogen transportation in the future, requires leak detection of hydrogen as a substitute for odor detection. Therefore, our company, in collaboration with Iwatani Corporation, has been developing a multi-point hydrogen leak monitoring network system utilizing the Kitakyushu City Environmental Future Technology Development Grant, completing a three-year demonstration starting from the fiscal year 2019. In the development for fiscal year 2021, we conducted demonstrations at the 'Hydrogen Pipeline Leak Simulation Evaluation Facility' established at the Kitakyushu Eco-Town Center, focusing on responsiveness tests of wireless hydrogen sensors and hydrogen selectivity evaluations in mixed gas environments. We also verified the appropriate pitch between handholes while varying the conditions of sensor response time and distance from the hydrogen leak point. By continuously disseminating reliable evidence obtained from this research and development from Kitakyushu City, we believe it will contribute to the early utilization of odorless hydrogen and the establishment of a hydrogen supply chain.
