Hydrogen Testing Facilities at TÜV SÜD National Engineering Laboratory

How TÜV SÜD are helping to address technical challenges
As a part of the worldwide drive to scale back greenhouse fuel emissions there is a pressing want to move in the course of clean fuels for energy. The use of hydrogen as a substitute for natural gasoline in the gasoline grid networks is seen as a significant contributor to meeting this goal. Manufacturers, fuel network corporations and governments are working carefully collectively to deal with a selection of technical challenges earlier than this modification can become a actuality. TÜV SÜD National Engineering Laboratory is a world-leading centre for move metrology research and development. To help tackle these challenges, it’s constructing a spread of hydrogen exams facilities. These facilities embrace the Hydrogen Domestic Gas Metering Test Facility, developed for testing smaller scale equipment at decrease pressures, coupled with the development of a gasoline primary flow normal take a look at facility, which offers decrease measurement uncertainty and greater options for basic metrology analysis, as nicely as larger hydrogen circulate price and stress ranges. This article describes the present hydrogen test services and those underneath growth at TÜV SÜD National Engineering Laboratory.
The hydrogen home gasoline metering test facility has been developed to provide a platform to analyze not solely the efficiency of flow meters, but additionally for different equipment associated to hydrogen operation, together with management valves, PRVs, regulators, warmth exchangers, and so on. in a hydrogen service. The test facility has been developed for small scale purposes and can deliver a variety of gas flows including hydrogen, methane, nitrogen or mixtures of hydrogen and methane. The take a look at facility is able to delivering as much as 38 Sm3/h of hydrogen to the system underneath take a look at at line pressures as much as 1500 mbar, with temperatures ranging from -25 to 55 ˚C. spmk700 can function with line sizes ranging from 5 to twenty mm. Construction was accomplished last yr and it’s now obtainable to be used by trade for product improvement or circulate testing of hydrogen gear and valves.
The switch over from pure gasoline to hydrogen may take place in a staged approach involving hydrogen/natural gas blends or direct change to pure hydrogen. Manufacturers can carry out an entire evaluation of apparatus performance across a spread of hydrogen to pure fuel compositions from 0 to one hundred pc hydrogen.
The hydrogen home gas metering take a look at facility has been specifically designed for low-pressure hydrogen purposes and TÜV SÜD recognised that there was additionally a necessity for a larger flow, higher strain test facility. TÜV SÜD has undertaken a project beneath the BEIS-funded Flow Programme to determine a Gas Primary Flow Standard Test Facility. Initially, it will operate with hydrogen, nitrogen and methane however with a view to be extended to carbon dioxide. The facility is currently in the detailed design stage and the plan is to have an operating envelope of up to a hundred Sm3/hr of gasoline with the ability to function as a lot as a hundred and twenty bar.
