The Oil and Gas Institute – National Research Institute (INiG-PIB) – is a Polish research institute that closely cooperates with the gas industry, including gas network operators, metering device producers, and renewable fuel producers. INiG-PIB has been conducting R&D work related to the injection of hydrogen into gas networks and the safety of using H2NG mixtures for several years. The INiG-PIB test stands, whether owned or planned to be built, enable the preparation and testing of the stability of pressure mixtures of H2NG with the addition of a selected gas odorant. A test stand for testing process gas chromatographs used to determine H2NG mixture composition will also be realized. INiG-PIB has created its own gas mixing plant that allows for the creation of gas mixtures with up to 7 components. Moreover, the Institute has several test benches for the calibration and testing of gas meters at low pressure, based on volumetric standards (drum and rotary gas meters) and turbine standards with traceability for air. INiG-PIB also conducts activities aimed at developing conformity assessment programs for products used in the hydrogen economy.
