How TÜV SÜD are helping to deal with technical challenges
As part of the worldwide drive to cut back greenhouse fuel emissions there is a pressing need to move in the path of clear fuels for energy. The use of hydrogen as a alternative for pure gasoline in the fuel grid networks is seen as a serious contributor to meeting this objective. Manufacturers, fuel community companies and governments are working closely collectively to address a number of technical challenges earlier than this modification can become a reality. TÜV SÜD National Engineering Laboratory is a world-leading centre for circulate metrology analysis and development. To help address those challenges, it’s constructing a variety of hydrogen tests amenities. These amenities embrace the Hydrogen Domestic Gas Metering Test Facility, developed for testing smaller scale gear at lower pressures, coupled with the development of a fuel primary circulate standard check facility, which provides lower measurement uncertainty and greater options for elementary metrology analysis, as properly as greater hydrogen flow fee and strain ranges. This article describes the present hydrogen check facilities and people under improvement at TÜV SÜD National Engineering Laboratory.
The hydrogen home gas metering take a look at facility has been developed to supply a platform to research not solely the efficiency of circulate meters, but also for other gear related to hydrogen operation, together with management valves, PRVs, regulators, warmth exchangers, etc. in a hydrogen service. The test facility has been developed for small scale functions and may ship a variety of gasoline flows together with hydrogen, methane, nitrogen or mixtures of hydrogen and methane. The check facility is capable of delivering as much as 38 Sm3/h of hydrogen to the system underneath check at line pressures up to 1500 mbar, with temperatures starting from -25 to 55 ˚C. It can function with line sizes starting from 5 to 20 mm. เกจวัดแรงดันถังออกซิเจน was accomplished final yr and it is now obtainable for use by business for product growth or flow testing of hydrogen gear and valves.
The change over from natural gas to hydrogen may take place in a staged method involving hydrogen/natural gasoline blends or direct change to pure hydrogen. Manufacturers can carry out a complete evaluation of equipment performance throughout a variety of hydrogen to pure gas compositions from zero to 100% hydrogen.
The hydrogen domestic gas metering take a look at facility has been particularly designed for low-pressure hydrogen purposes and TÜV SÜD recognised that there was also a necessity for a larger circulate, higher stress take a look at facility. TÜV SÜD has undertaken a challenge under the BEIS-funded Flow Programme to determine a Gas Primary Flow Standard Test Facility. Initially, it’ll function with hydrogen, nitrogen and methane but with a view to be prolonged to carbon dioxide. The facility is presently within the detailed design stage and the plan is to have an working envelope of as much as 100 Sm3/hr of gasoline with the flexibility to operate as much as a hundred and twenty bar.
