How TÜV SÜD are serving to to address technical challenges
As a part of the worldwide drive to cut back greenhouse gasoline emissions there is a urgent need to move in course of clean fuels for energy. The use of hydrogen as a alternative for natural gasoline within the gas grid networks is seen as a major contributor to assembly this objective. Manufacturers, fuel community companies and governments are working intently collectively to handle numerous technical challenges earlier than this change can turn out to be a actuality. TÜV SÜD National Engineering Laboratory is a world-leading centre for move metrology research and improvement. To assist handle these challenges, it’s constructing a spread of hydrogen checks facilities. These amenities include the Hydrogen Domestic Gas Metering Test Facility, developed for testing smaller scale equipment at lower pressures, coupled with the event of a gasoline major circulate standard take a look at facility, which offers decrease measurement uncertainty and larger options for elementary metrology research, as nicely as greater hydrogen flow fee and strain ranges. This article describes the existing hydrogen take a look at services and those beneath development at TÜV SÜD National Engineering Laboratory.
เกจวัดแรงดันอากาศ metering check facility has been developed to provide a platform to research not only the performance of circulate meters, but additionally for other gear associated to hydrogen operation, together with control valves, PRVs, regulators, heat exchangers, and so forth. in a hydrogen service. The test facility has been developed for small scale functions and may ship a range of gasoline flows including hydrogen, methane, nitrogen or mixtures of hydrogen and methane. The take a look at facility is capable of delivering up to 38 Sm3/h of hydrogen to the device underneath check at line pressures as a lot as 1500 mbar, with temperatures starting from -25 to 55 ˚C. It can function with line sizes ranging from 5 to twenty mm. Construction was completed final 12 months and it’s now obtainable to be used by industry for product development or flow testing of hydrogen tools and valves.
The swap over from natural gasoline to hydrogen may take place in a staged approach involving hydrogen/natural gas blends or direct switch to pure hydrogen. Manufacturers can perform an entire assessment of equipment efficiency throughout a range of hydrogen to pure fuel compositions from zero to 100 percent hydrogen.
The hydrogen domestic fuel metering check facility has been specifically designed for low-pressure hydrogen functions and TÜV SÜD recognised that there was also a necessity for a larger flow, higher stress take a look at facility. TÜV SÜD has undertaken a challenge underneath the BEIS-funded Flow Programme to establish a Gas Primary Flow Standard Test Facility. Initially, it will operate with hydrogen, nitrogen and methane however with a view to be prolonged to carbon dioxide. The facility is at present in the detailed design stage and the plan is to have an working envelope of as much as one hundred Sm3/hr of gasoline with the power to operate as much as 120 bar.
