How TÜV SÜD are helping to address technical challenges
As part of the global drive to reduce greenhouse gas emissions there is a pressing want to maneuver towards clear fuels for power. The use of hydrogen as a substitute for pure gas within the gasoline grid networks is seen as a major contributor to meeting this objective. Manufacturers, gasoline community firms and governments are working carefully collectively to address a selection of technical challenges earlier than this alteration can turn out to be a actuality. TÜV SÜD National Engineering Laboratory is a world-leading centre for move metrology analysis and growth. To help handle those challenges, it’s building a range of hydrogen checks amenities. These amenities embrace the Hydrogen Domestic Gas Metering Test Facility, developed for testing smaller scale gear at decrease pressures, coupled with the development of a fuel major flow normal take a look at facility, which offers decrease measurement uncertainty and larger options for fundamental metrology research, as nicely as higher hydrogen flow rate and stress ranges. This article describes the prevailing hydrogen take a look at services and those under development at TÜV SÜD National Engineering Laboratory.
The hydrogen home fuel metering check facility has been developed to provide a platform to analyze not solely the efficiency of circulate meters, but also for different equipment associated to hydrogen operation, including control valves, PRVs, regulators, heat exchangers, and so on. in a hydrogen service. The test facility has been developed for small scale purposes and might deliver a spread of gas flows including hydrogen, methane, nitrogen or mixtures of hydrogen and methane. The test facility is capable of delivering up to 38 Sm3/h of hydrogen to the system under take a look at at line pressures up to 1500 mbar, with temperatures starting from -25 to 55 ˚C. It can operate with line sizes starting from 5 to twenty mm. Construction was accomplished last 12 months and it is now out there for use by trade for product growth or circulate testing of hydrogen equipment and valves.
The swap over from pure fuel to hydrogen might happen in a staged strategy involving hydrogen/natural gas blends or direct switch to pure hydrogen. เกจ์ออกซิเจนsumo can carry out a complete evaluation of apparatus efficiency across a spread of hydrogen to natural gasoline compositions from zero to 100% hydrogen.
The hydrogen domestic fuel metering test facility has been particularly designed for low-pressure hydrogen functions and TÜV SÜD recognised that there was additionally a necessity for a larger flow, higher stress check facility. TÜV SÜD has undertaken a venture 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 presently within the detailed design stage and the plan is to have an working envelope of up to one hundred Sm3/hr of fuel with the power to operate up to a hundred and twenty bar.
