  2. ISO 19880-1 Scope: Hydrogen Station • Hydrogen production / delivery system • Compression • Gaseous hydrogen buffer storage; • Pre-cooling device; • Gaseous hydrogen dispensers. • FCEV Vehicle Interface

  3. ISO TR 19880-1 Overview • General design & maintenance requirements • Equipment & components • Hydrogen and Electrical Safety • Layout & safety distance description • Safety Methodologies • Fueling protocol & interface Hydrogen Dispenser FCEV Testing • Quality control • Alignment of Pressure Terminology and Values

  7. Station Acceptance TestingDevice Guidelines • - On-site “Field test” before normal operation of station • - periodic - e.g. every year for verification of safety relevant PLC

  8. ISO 19880-1 Annex B Testing with Hydrogen Station Test Apparatus Table B.1: Dispenser function tests

  9. US “HyStep” HSTA ExampleSafety and Performance Testing Hydrogen Station Test Apparatus(From US DOE/Sandia/NREL) SAE J2601 Testing to All Categories: • Three 77L Type IV Quantum tanks • 3.1 kg H2 capacity at 70 MPa NWP • Allows for testing all SAE J2601 • 3kg/6kg/9kg SAE J2799 Communications Test • Abort/ Halt • Data Loss then Abort and resume • ID Protocol • Protocol Version # • CHSS Volume • Receptacle Type • Fueling Command • Measured Pressure/ Temperature

  10. Safety Methodology: H2 FuelingRisk Assessment Lead: Lars Zimmermann (Germany) from Shell

  11. Fueling Components Updated Cycle Requirements A fueling assembly should consist of a breakaway device, a hose(s), a nozzle and connectors between these components. Suitability of the fueling assembly components for the specified service conditions and cycle life should be demonstrated by type testing. Type testing to enable a rated pressure to MAWP could for example include: • a hydrostatic pressure test to 375 % NWP; • 100,000 pressure cycles to 125 % NWP; • 190 pressure cycles to 150 % NWP.

  12. P-Member Survey results – Example: Status Clearance distances

  13. Safety Distance Methodology:Quantitative Risk Assessment Example of a risk-informed approach to safety distances See ICHS Presentation: “HYRAM – a methodology and toolkit for quantitative risk assessment of hydrogen systems”

  14. Status and Path Forward • ISO TR 19880-1 passed P-Member ballot in October, 2015 • ISO TC 197 WG 24 will complete the comment review and submit for publication to ISO in November, 2015. • International Standard ISO 19880-1 Planned to finish by the end of 2016. • ISO IS 19880-1 to be used as a basis for the EU Alternative Fuels Directive (replacing ISO TS 20100) for hydrogen stations in Europe (including the 400 recently announced in Germany) starting in 2017-.

  15. Informational: H2 Fueling & Quality Open Data Sharing Website with Reports Ca. 1000 Views/400 Data Downloads and Official Release is 10/19!

  16. Questions ? (Hydrogen Fueling Infrastructure Developments) • Europe: • Germany • Demo-project Clean Energy Partnership15 public stations + 35 in process in 2016 • 400Privately funded in planning until 2023 • Scandinavian Countries • Scandinavian Hydrogen Highway, • 10 public stations / 6 in process/ 15 planned for 2016+. • Japan • 100stationsplanneduntil2016+ • 1000stations in discussion until 2025 • California / US • ZEV Mandate10 public station, / • 45 more in process for 2016 • (100 Total planned to 2020) • US/ East Coast • East Coast Hydrogen Highway evaluation (TBD)

  17. ISO TS 20100ISO 19880-1 Different Direction from previous ISO TS 20100: • Detailed guidance on hydrogen dispensing. Reference SAE J2601 as possible means of fueling. • More detailed guidance on the acceptance process (both safety and performance aspects) • Study into variation of existing safety distances used currently around the world Issues trying to address: • Interaction between vehicle and dispenser – what is the minimum acceptable reliability of fueling control (Risk Assessment Approach). • Understanding of Limits on dispensing pressures internationally, specifically the EU – what is needed to enable station side component filling of a vehicle 125 % NWP (not possible in EU currently). Goal to raise PRV setting to 138% NWP. • Hydrogen quality – how to control quality without burdening stations with excessive, unnecessary analysis requirements (leading to creation of new WG 28 in ISO TC 197) • Safety distances – status and trying to find consensus on an approach that is suitable for countries where there are currently very different methodologies in place

  18. Backup Slides

  19. Dispensing Components and Fueling Protocol Pressure Mismatch • Some fueling protocols go to a pressure of 125% during filling, however European dispenser components only rated to 125 % NWP. • PRV needs to be set at the so-called “rated pressure” in Europe • In the EU, this precludes fueling to 125 % NWP where PRVs are used as the over-pressure protection in case of the dispenser basic control system failure

  20. ISO 19880-1 Pressure HarmonizationTable for fueling components • Notes: • The proposed test level matches the maximum pressure expected during PSV relieving. • Other test pressure may be required according to ISO 15,649 or national regulations • Component Rating needs to be valid at maximum and minimum allowable material temperatures • Pressures used in hydrogen fueling of Road Vehicles in ISO TR 19880-1

  21. External Informative References Where ISO/ IEC references do not exist, WG24 has chosen select external references such as: SAE • J2601 Fueling Protocols for Light Duty Gaseous Hydrogen Surface Vehicles • SAE J2799 Hydrogen Surface Vehicle to Station Communications Hardware and Software ASTM • D7606-11 Sampling of High Pressure Hydrogen and Related Fuel Cell Feed Gases • D7650-13 Standard Test Method for Sampling of Particulate Matter in High Pressure Hydrogen
