How TÜV SÜD are helping to address technical challenges
As part of the worldwide drive to scale back greenhouse gas emissions there’s a pressing need to move in path of clear fuels for energy. The use of hydrogen as a substitute for natural gasoline in the fuel grid networks is seen as a major contributor to meeting this objective. Untold , fuel network firms and governments are working closely collectively to deal with a selection of technical challenges before this alteration can turn into a actuality. TÜV SÜD National Engineering Laboratory is a world-leading centre for circulate metrology research and growth. To assist tackle those challenges, it’s constructing a range of hydrogen tests amenities. These services include the Hydrogen Domestic Gas Metering Test Facility, developed for testing smaller scale gear at lower pressures, coupled with the event of a fuel major circulate commonplace take a look at facility, which offers decrease measurement uncertainty and higher choices for fundamental metrology research, in addition to greater hydrogen flow fee and pressure ranges. This article describes the prevailing hydrogen take a look at amenities and people under growth at TÜV SÜD National Engineering Laboratory.
The hydrogen domestic gas metering check facility has been developed to supply a platform to research not solely the efficiency of flow meters, but in addition for different equipment related to hydrogen operation, together with management valves, PRVs, regulators, heat exchangers, and so on. in a hydrogen service. The check facility has been developed for small scale purposes and can ship a variety of fuel 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 underneath take a look at at line pressures up to 1500 mbar, with temperatures starting from -25 to fifty five ˚C. It can function with line sizes ranging from 5 to 20 mm. Construction was accomplished last 12 months and it’s now obtainable for use by trade for product development or move testing of hydrogen gear and valves.
The switch over from pure gas to hydrogen may happen in a staged approach involving hydrogen/natural gas blends or direct change to pure hydrogen. Manufacturers can carry out a complete evaluation of equipment efficiency across a spread of hydrogen to natural fuel compositions from 0 to 100 percent hydrogen.
The hydrogen domestic fuel metering check facility has been specifically designed for low-pressure hydrogen purposes and TÜV SÜD recognised that there was also a necessity for a larger flow, greater pressure check facility. TÜV SÜD has undertaken a project under the BEIS-funded Flow Programme to ascertain a Gas Primary Flow Standard Test Facility. Initially, it will function with hydrogen, nitrogen and methane but with a view to be prolonged to carbon dioxide. The facility is currently in the detailed design stage and the plan is to have an operating envelope of up to one hundred Sm3/hr of fuel with the power to function up to 120 bar.
