Bavaria's Minister of Economic Affairs Hubert Aiwanger has opened a new metrological testing laboratory of the Bavarian State Office for Weights and Measures. It is to test measuring devices for H2 tanks and e-charging columns.
The new facility of the Bavarian State Office for Weights and Measures (LMG), located in Grafenau, 190 kilometers northwest of Munich, is to become a "state-of-the-art metrological laboratory." This was announced by Hubert Aiwanger (Free Voters) at the opening ceremony on July 16. From the Lower Bavarian location, measuring devices of hydrogen tanks and e-charging columns are to be tested to reliably and bindingly ensure measurement in compliance with calibration law - just as is the case, for example, with scales in the retail trade and fuel pumps at gas stations.
"Metrological monitoring by the LMG test laboratory ensures that every measuring instrument subject to legal metrology is operated in compliance with the law," explained the Bavarian Minister of Economic Affairs. In this way, he said, the testing laboratory will play an important role in the energy transition. "Where the testing laboratory is headed is shown by testing facilities for sustainable energy sources. For example, I find the test facility for calibrating an e-charging column just as interesting as for innovative volume measurement systems for hydrogen." The goal, he said, must be to ensure that, with the increase in electrolysers and hydrogen filling stations, calibration approval and testing procedures follow uniform standards, for example, for decanting and measurement.
In Grafenau, for example, there is a quantity measurement system for hydrogen trailers to transport hydrogen to the point of use. This high-pressure gas calibration laboratory of "Trigas FI GmbH" from Neufahrn is important for hydrogen filling stations and hydrogen delivery systems, as Aiwanger was shown on site by the CEO of Trigas Fi, Thomas Steuer. Since the highly compressed hydrogen is transported in trailer vehicles, accurate measurement of the hydrogen produced, transported and consumed tips the scales for billing.
In the future, this new technology will be tested and approved in Grafenau, among other places. This should enable manufacturers and operators of hydrogen filling stations and electrolysers to provide energy consumers with reliable information on the amount of hydrogen used.
The Bavarian State Office for Weights and Measures is headquartered in Bad Reichenhall, Upper Bavaria, on the border with Austria. The weights and measures administration has a regional structure in Bavaria: Weights and Measures Offices and testing laboratories monitor compliance with the national Weights and Measures Act in several Bavarian cities. In addition to Grafenau, there are also locations in Augsburg, Landshut, Nuremberg, Munich, Regensburg and Passau, for example.
