In this tech talk, Steven had the pleasure of discussing Hydrogen Refueling Stations - Measurement with Christian Wirl, Portfolio Manager at WIKA Group.
Learn about Hydrogen Refueling Stations - Measurement
Steven Oji and Christian Wirl explain the use of pressure indicators and transmitters at various stages of the hydrogen refueling process, such as at the inlet of a compressor or at storage tanks. He also discusses the design of manual valves. The gauge Christian has brought along contains Swiss Movement technology, which is used to transfer the movement of the burdon tube and measure pressure within the system. Christian further discusses the importance of temperature control in hydrogen refueling stations (HRS). He explains that hydrogen gas warms up when it expands. It is important to keep the temperature of the gas below 85 degrees when filling a vehicle with hydrogen. To do this, the gas is typically cooled to around -40 degrees before it is dispensed.
Christian discusses the use of temperature sensors and transmitters in the hydrogen refueling process, which are used to measure the temperature of the gas and transmit this information to the control system. These sensors and transmitters must be explosion-proof and made of materials that can withstand high pressures, such as 316L Steel (1.4404).
