N2 - To safely handle hydrogen as an energy carrier, it is important to understand the behaviour of hydrogen. There are many methods available for measuring hydrogen concentration using conventional sensors; however, it is difficult to detect hydrogen gas from a distance. Here, we observed hydrogen behaviour over a narrow region of space with a Raman scattered light sensor. Generally, there is some delay in conventional sensors; however, there was almost no delay with the use of our sensor. We used 1- and 6-mm diameter holes as spout nozzles to change the initial velocities. To confirm the effectiveness of our method, we used hydrogen visualization sheets, which became transparent when hydrogen was detected enabling the hydrogen movement to be visualized. Hence, we observed the behaviour of hydrogen gas in a small container and optimized the device to increase the measurement distance from 4.5 to 7.5 m.
