Test Standards for Hydrogen Refuelling Stations

Online 14:00 GMT

Accurate quantification of hydrogen dispensed at refuelling stations is crucial for the uptake of light duty hydrogen fuelled vehicles.

Hydrogen fuel cell electric vehicles (FCEV) produce zero emissions at the tailpipe and therefore could play a key role in reaching the net-zero emission targets of the EU and the UK. However, one of the main barriers to the uptake of FCEVs is the lack of adequate refuelling infrastructure. The primary metrological roadblock to this is the verification of the flow measurements from hydrogen refuelling station (HRS) dispensers, as this measure will translate to how much consumers are charged for the fuel. We have confidence today in the amount of petrol or diesel dispensed at forecourts, and consumers expect to be treated fairly if they were to fill their vehicle tanks with hydrogen gas as well.

However, unlike with petrol or diesel, it is not as simple to measure hydrogen dispensed into the vehicle’s tank. Several measurement institutes across Europe, the US, and the Asia have built test standards for verifying the amount of hydrogen dispensed by HRS.

This webinar, presented by Dr. Revata Seneviratne, looks that TÜV SÜD National Engineering Laboratory’s light-duty hydrogen field test standard (HFTS) which is United Kingdom’s first test standard to verify hydrogen dispensers for light-duty FCEVs.

FOCUS TOPICS

  • Design and build of TÜV SÜD’s light-duty HFTS, with details around safety when operating the HFTS at HRS and the uncertainty of measurement
  • Commissioning of the measurement system on the HFTS using nitrogen gas
