The realization of odorless hydrogen supply through pipelines, assuming large-scale hydrogen transport in the future, requires leakage hydrogen detection as a substitute for odor detection. Therefore, our company has been developing a multi-point leakage hydrogen monitoring network system in collaboration with Iwatani Corporation, utilizing the Kitakyushu City Environmental Future Technology Development Grant, and has completed a three-year demonstration starting from the fiscal year 2019. In the development for fiscal year 2021, we conducted demonstrations at the 'Hydrogen Pipeline Leakage Simulation Evaluation Facility' established at the Kitakyushu Eco-Town Center, focusing on response 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 leakage 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.
