Who is the National Hydrogen Association?
5
Hydrogen Industry Panel on Codes (HIPOC)

• Continuation/re-branding of the ICC Ad Hoc
  Committee on Hydrogen Gas
• ICC Ad Hoc Committee had an 80 success rate with
  hydrogen code proposals
• Expanded scope
• Now include NFPA codes
• Seeks to harmonize (to the extent possible) ICC
  and NFPA
• HIPOC serves as a conduit for information needed
  to improve the hydrogen sections of the ICC and
  NFPA codes (for ex., separation distance data)
• Diverse panel of well-known industry experts with
  staff from ICC, NFPA, NHA and DOE.

16 Hydrogen Proposals

• B-List (8 other proposals)
• International Fuel Gas Code-Scoping Changes
• FG54 (Tomberlin) H2 PipingConcealed Locations
• FS37 (Brazil) Fire barrier definition
• M56 (Marts/Telcordia) Ventilation requirement
  moved from exhaust to ventilation
• F53 (Marts/Telcordia) Lithium Metal Polymer
  batteries
• F154 (Joseph/HIPOC) Vehicle overpressure
  protection
• F155 (Joseph/HIPOC) Indoor fast-fill
  dispensing
• F156 (Joseph/HIPOC) Electrostatic discharge for
  fueling pads

F54 Required attendant for battery storage
ventilation systems

• F54 (Kilpatrick/SeattleFD)
• Requires that the ventilation systems in 608.6.1
  (room ventilation) and 608.6.2 (cabinet
  ventilation) have an additional requirement for
  supervision by an approved central, proprietary,
  or remote station service or the activation of
  an audible and visual signal at a constantly
  attended on-site location.
• This change will increase the cost of the
  ventilation system.

10
F157 Consistent listing of lighter-than-air
gas detection systems

• F157 (Rogers/Kitsap)
• Changes gas detection systems from requiring to
  be approved to requiring that they be listed.
  
• In other natural gas and hydrogen sections
  (2208.2.2 and 2209.2.2), some types of equipment
  shall be approved, some listed and others
  listed and labeled.
• In those other sections, gas detection systems
  are all required to be listed.
• This proposal maintains consistency by requiring
  gas detection systems in repair garages for
  vehicles fueled by lighter-than-air fuels to be
  listed.
• Flagged because it changes gas detection systems
  for repair garages from only needing to be
  approved to now needing to be listed.

11
F172 Addressing hydrogen cylinders stored in
outdoor cabinets

• F172 (Buehler/Plug)
• Current International Fire Code and NFPA 55
  sections do not deal with outdoor hydrogen
  storage cabinets, only naked cylinders or
  indoor cabinets
• Proposal is to facilitate the placement of
  bottled hydrogen in outdoor cabinets in proximity
  to low powered electrical equipment.
• Interested parties should view the actual code
  change to note the maximum allowed quantity of
  hydrogen that can be stored in an outdoor cabinet
  and separation distances to both combustible
  waste/vegetation and electrical equipment.

12
F193 Telecomm cabinets and transfer switches
near outdoor hydrogen cabinets

• F193 (Buehler/Plug)
• Allows the location of Network Equipment Building
  Standards (NEBS) rated telecommunications
  cabinets within 5 feet of the outdoor hydrogen
  cabinets discussed in F172.
• Allows National Electrical Manufacturers
  Association (NEMA) rated outdoor transfer
  switches to be located also within 5 feet.
• Transfer switches will be located between 0 and 4
  feet above ground.
• According to the proponent, this amendment is to
  facilitate the placement of bottled hydrogen in
  proximity to low powered electrical equipment.
• Flagged because more understanding is desired.

13
F175 Diking around above ground LH2 storage

• F175 (Dean/NASFM)
• Proposal may increase the likelihood of a
  flammable vapor cloud (possibly with liquefied
  air) forming near any cryogenic liquid leak
• Proponent believes that overall safety is higher
  because this language would contain the liquid
  from moving off the property (reduces affected
  area).
• Proposal gives additional requirements for LH2 in
  general sections which describe outdoor
  stationary storage containers of any cryogenic
  fluid.
• See also F191

14
F191 Movement of LH2 language and new LH2 tank
requirements from CGA

• F191 (Fluer/CGA)
• Several parts
• Keeps Chapter 32 (Cryogenic Fluids) as a general
  chapter (not specific to any particular cryogenic
  liquid).
• As a result, proposed title change to Chapter 35
  (currently Flammable Gases) to become Flammable
  Gases and Flammable Cryogenic Fluids
• This simple change could have a potential impact
  on F175 (Dean/NASFM) which proposes
  hydrogen-specific changes to the general chapter
  32.
• Language proposed in 3501.1 which proposes that
  above ground hydrogen storage systems shall be in
  accordance with Chapter 22 (Motor fuel-dispensing
  facilities and repair garages) could have an
  impact on F172 (Buehler/Plug) which deals with
  above ground storage of outdoor hydrogen
  cabinets.

15
F229 New requirements for indoor hydrogen
storage

• F229 (Dean/NASFM)
• Proposal adds new language to the International
  Fuel Gas Code providing requirements for indoor
  storage of hydrogen.
• Comparison to other sections in the International
  Fire Code that pertain to indoor hydrogen
  storage?
• According to the proponent, these additions
  differ from anything in existing code in that
  they stipulate pressure limits, not just
  quantities of hydrogen gas.
• Ventilation and alarms are required so that
  should there be a gas leak, it is detected and
  there is no chance of asphyxiation.

16
F194 Guidance for metal hydride systems

• F194 (Fluer/CGA)
• Similar language was approved and then deleted
  during the last two code cycles
• During deletion, committee requested it would be
  better if the code included, in codified form,
  the safeguards that are currently used by the
  industry for the systems that are currently in
  use in the field.
• Proposed language addresses above concerns
• Language treats metal hydride cylinder as a
  storage system, classified based on hydrogen, not
  hydride
• Since the metal hydride is expected to always
  remain in its tank, only the substance entering
  and leaving the tank should be regulated
• Absence of this language will give the code
  official no guidance on how to regulate metal
  hydride systems
