Standards Development
The scope is fueling stations for light and heavy-duty transportation
This NWIP will help with international harmonization of heavy duty, Cryo Compressed, and liquid hydrogen in addition to light duty gaseous stations. The European Alternative Fuels Infrastructure Regulation references EN 17127. EN 17127 has an informative reference to ISO 19880-1 for guidance on all hydrogen stations and should be updated with this new ISO standard. Minimum requirements for multiple gaseous fuelling station types are to be provided, as foreseen in the ISO TC/197 NP1655 “General hydrogen station requirements and update ISO 19880-1” document.
This will facilitate international harmonization and buildout of hydrogen at scale with adoption of fast flow heavy-duty (buses and trucks, etc.) hydrogen fuelling stations. The purpose is for one working group to be able to develop a new document and update an existing 19880-1 and create a new standard ISO 198XX such that it encompasses all hydrogen fuelling stations including references to High-Flow, Heavy Duty Fuelling (WG5, WG 24), Liquid Hydrogen Fuelling methodologies (WG 35), and Cryo Compressed fuelling methodologies (WG 36). Also, this would encompass liquid hydrogen delivery stations with high flow fueling for heavy duty vehicles - see diagram 1 in the annex.
Diagram 2, also in the annexe, is an outline for the system level requirements for the 3 difference hydrogen station streams. With the oval are the two standards graphically shown to be included in this new working group. The arrow is to correlate to the split in requirements from the previous figure.
Diagram 3 (in the annexe) is the representation of how these standards could fit into the TC 197 Structure including overarching elements for Hydrogen Quality and Stationary Storage. This meant to illustrate an example to have top down requirements, logical systems approach.
One goal is to allow for co-location of different types of hydrogen dispensing (GH2/LH2/CcH2) in proximity on the same forecourt.
The intention is to assist worldwide in harmonization of hydrogen station standardization for general requirements.
This document defines the minimum general requirements for public and non-public hydrogen fuelling stations that dispense either gaseous, Cryo Compressed or liquid hydrogen for light and heavy-duty, on and off-road hydrogen powered vehicles, rail and marine applications. This includes design, installation, commissioning, operation, inspection and maintenance requirements, and safety. In addition, multimodal stations will be addressed. This document is not applicable to the dispensing of hydrogen to metal hydride applications. Since this document is intended to provide minimum requirements for fuelling stations, manufacturers can take additional safety precautions as determined by a risk management methodology to address potential safety risks of specific designs and applications.
