“…A Raman lidar system is one of the remote hydrogen gas detection techniques. It is able to measure the range of the hydrogen gas distribution and hydrogen gas concentration densities remotely [1,2,[8][9][10][11][12][13]. PRIVALOV suggested the method of the hydrogen gas molecules detection by using the Raman lidar system with a 532 nm wavelength laser [8]; 100 mJ and 400 mm diameter telescope was used in 2004 [6].…”

A Raman lidar system is able to detect the range of gas distribution and measure the hydrogen gas concentration remotely. This paper discusses the development of a photon counting Raman lidar system for remotely measuring the hydrogen gas concentration. To verify the developed photon counting Raman lidar system, experiments were carried out in outdoor conditions. As the results indicate, the developed photon counting Raman lidar system is possible to measure 0.66 to 100 vol% hydrogen gas concentrations at a distance of 30 m. In addition, the measuring average error measured 0.54% and the standard deviation is 2.42% at a distance of 30 m.

Now, Hydrogen gas is of particular interest as new energy source and dangerous material in nuclear facility. Fuel cell is started to use in home power generation system in 2008 and fuel cell vehicle (FCV) is commercialized from 2014 in Japan. On contrary, the Great East Japan Earthquake revealed the fear of hydrogen explosion on Fukushima Nuclear Power plant in 2011. Contact type hydrogen sensors induce changes on the gas flow, and the actual concentration cannot be known. It is hard to get the gas concentration distribution in hydrogen leakage area. We focused on optical remote sensing for the hydrogen detection. Raman scattering detection was accomplished for the hydrogen gas with a compact Diode Pumped Solid State (DPSS) laser-based Raman lidar. The quantitative measurement was conducted on the hydrogen gas concentration of 1-100% and the detectable distance of <50 m. Next, a LED-based mini Raman lidar was developed with the same optical design as the former one in viewpoints of its robust operation and usability in the nuclear facility. The high-speed photon counter was developed to follow the high repetition frequency of LED pulse of >500 kHz, and the quantitative measurements of hydrogen concentration were conducted on lab-experiment and at outdoor.

“…Nevertheless, H 2 has a strong Raman cross section and Raman lidar is recognized as one of the most appropriate technique for remote H 2 detection [4]. H 2 measurement by Raman lidar has already been demonstrated in the past for pure H 2 point leaks at short range [5]. However, the Shikoku Research Institute system is designed to probe a limited close area and does not allow monitoring over hundreds of meters.…”

A multi-channel Raman lidar has been developed, allowing for the first time simultaneous and high-resolution profiling of hydrogen gas and water vapor. The lidar measures vibrational Raman scattering in the UV (355 nm) domain. It works in a high-bandwidth photon counting regime using fast SiPM detectors and takes into account the spectral overlap between hydrogen and water vapor Raman spectra. Measurement of concentration profiles of H and HO are demonstrated along a 5-meter-long open gas cell with 1-meter resolution at 85 meters. The instrument precision is investigated by numerical simulation to anticipate the potential performance at longer range. This lidar could find applications in the French project Cigéo for monitoring radioactive waste disposal cells.
