Raman lidar for detection of leaks from tank and engines of hydrogen-fueled mining transportation

The mining industry uses equipment that consumes large amounts of energy. In mining operations, diesel equipment is widely used due to its flexibility, load capacity and adaptability to various operating conditions. However, when using diesel mining equipment, there is a high consumption of diesel fuel and high levels of greenhouse gas emissions, mainly carbon monoxide. Using hydrogen as a fuel not only offers the opportunity to decarbonize transportation and the mining industry, but also significantly reduces local air pollution. The use of hydrogen as a fuel to drive engines of power plants and transport facilities in the mining industry requires the development of equipment to control the leakage of hydrogen from storage elements and fuel supply to the engines. The solution to the problem of monitoring hydrogen leaks from fuel tanks of mining vehicles and power equipment that ensures the operation of mining enterprises using Raman lidar (RSL) is considered. The graphical dependences of the time of measurement of hydrogen concentration as a function of the distance to the place of hydrogen leak are presented. By calculating the lidar equation, it was established that the minimum time for measuring the hydrogen concentration in the air with the Raman lidar will be at a wavelength of 532 nm.
