Hydrogen Testing Facilities at TÜV SÜD National Engineering Laboratory

How TÜV SÜD are helping to deal with technical challenges
As part of the global drive to cut back greenhouse gas emissions there is a pressing want to move towards clear fuels for power. The use of hydrogen as a replacement for natural gasoline within the gasoline grid networks is seen as a significant contributor to assembly this objective. Manufacturers, fuel community corporations and governments are working intently collectively to address a variety of technical challenges earlier than this change can turn into a actuality. TÜV SÜD National Engineering Laboratory is a world-leading centre for flow metrology analysis and development. To assist handle these challenges, it’s building a spread of hydrogen checks amenities. These services embrace the Hydrogen Domestic Gas Metering Test Facility, developed for testing smaller scale gear at decrease pressures, coupled with the development of a gas major circulate normal take a look at facility, which supplies lower measurement uncertainty and greater options for fundamental metrology research, in addition to higher hydrogen flow fee and strain ranges. This article describes the existing hydrogen check facilities and those underneath improvement at TÜV SÜD National Engineering Laboratory.
The hydrogen domestic gas metering check facility has been developed to supply a platform to analyze not only the efficiency of circulate meters, but in addition for different tools related to hydrogen operation, together with control valves, PRVs, regulators, warmth exchangers, and so forth. in a hydrogen service. The test facility has been developed for small scale purposes and may ship a spread of gas flows including hydrogen, methane, nitrogen or mixtures of hydrogen and methane. The check facility is capable of delivering up to 38 Sm3/h of hydrogen to the system under take a look at at line pressures as much as 1500 mbar, with temperatures ranging from -25 to 55 ˚C. It can operate with line sizes starting from 5 to twenty mm. Construction was accomplished final yr and it’s now available for use by trade for product improvement or circulate testing of hydrogen equipment and valves.
The change over from natural gasoline to hydrogen could happen in a staged approach involving hydrogen/natural gas blends or direct switch to pure hydrogen. Manufacturers can perform a whole assessment of equipment efficiency across a variety of hydrogen to pure gas compositions from zero to 100 percent hydrogen.
The hydrogen home gas metering check facility has been particularly designed for low-pressure hydrogen applications and TÜV SÜD recognised that there was also a necessity for a bigger move, higher pressure take a look at facility. TÜV SÜD has undertaken Prize under the BEIS-funded Flow Programme to determine a Gas Primary Flow Standard Test Facility. Initially, it’s going to function with hydrogen, nitrogen and methane but with a view to be prolonged to carbon dioxide. The facility is currently within the detailed design stage and the plan is to have an operating envelope of as a lot as a hundred Sm3/hr of gasoline with the ability to operate up to one hundred twenty bar.
