Optical Fiber Hydrogen Sensor_Hydlog10

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.

We will introduce products and technologies that are most suitable for the theme of the exhibition, "Environmental solutions such as low-carbon and global warming prevention technologies, purification and pollution prevention technologies appropriate for the era of the global environment." Exhibit: Hydrogen Visualization System (Booth No. EN-05) This is a fusion of our multi-point synchronous measurement technology and cutting-edge sensors. Please feel free to stop by our booth.

In the "Kyushu University Special Feature" of the Nikkan Kogyo Shimbun (11/30), we are promoting through an advertisement. Please check the press release summarizing the "Hydrogen Visualization System" adopted for the next-generation rocket tests by ISAS/JAXA.

We will be exhibiting at the world's largest exhibition for research, development, and manufacturing of fuel cells, at the Fukuoka Hydrogen Strategy Conference booth. We will showcase our products and demonstrations related to "hydrogen detection," which we have been working on since 2007, so we would be grateful if you could stop by our booth during your visit.
