Results of the ICC Code Development Hearings

With contributions from Darren Meyers, International Code Council

The ICC Code Development hearings held September 20-October 1, 2006 at Disney's Coronado Spring Resort, Walt Disney World®, Florida had mixed results for the 15 code changes relating to hydrogen. Just less than half of the proposals were “recommendedfor approval” at the Final Action Hearings which are scheduled for May 21-27, 2007 in Rochester, NY.

Although some proposals were recommended for approval and others were not, the “recommendation” means that the code proposals have neither been officially approved or disapproved yet. That will happen at the Final Action Hearings in May. Rather, each proponent (and opponents, if any) had the chance to present their proposal before the ICC membership and the appropriate code development committee to get reactions to and debate the suggested changes. This allows the proponent to make necessary modifications to his/her proposal before the ICC membership votes on it at the Final Action Hearings. At this point, the main difference between a proposal that was recommended for disapproval or approval is that proposals recommended for approval only need a simple majority vote (50% + 1) to be finally approved; on the other hand, proposals recommended for disapproval at the Code Development Hearings need a 2/3 vote to become approved at the Final Action Hearings.

The results of the September hearings and further explanation of the process are included below.

Official reasoning from the Code Development Committee on why certain proposals were recommended for disapproval will be published by Nov 7, 2006. After these are available, NHA staff will provide a more verbose explanation of how each proposal fared at September’s Code Development Hearings and further analysis on what needs to be accomplished in order for proposals to be approved in May.

**D-ASF: Disapproved (by the code development committee). However, there was a motion from the floor for "As Submitted," and it was successful. Thus, “As Submitted from the Floor.” Both actions will proceed forward to the Final Action Hearings in May.

More on Code Development Hearings vs. Final Action Hearings
As explained in the August issue of the Hydrogen and Fuel Cell Safety Report (HFCSR, AUG 06), the Code Development Hearings are the first of two stages to either approve or disapprove code changes. The second stage is the Final Action Hearings.

The key differences between the two stages are that in the Code Development Hearings the code change proposals are heard by acommittee and the result of their decision is a recommendation on how the ICC membership (code enforcement and fire officials, architects, engineers, builders, contractors, elected officials, manufacturers and others in the construction industry) might want to vote at the Final Action Hearings-approve or disapprove.

In the second stage, the Final Action Hearings, as you might expect, the proposals are heard by the ICC membership and their vote is thefinal decision on whether a code change proposal is approved or disapproved. At the Final Action Hearings, the same committee who recommended an outcome at the earlier Code Development Hearings will hear the proposals again, but this time in more of a moderating/advisory role.

At both the Code Development Hearings and Final Action Hearings, the proponent, supporters and opponents are allowed a short time to speak to the committee and ICC membership about any code change. Anyone, ICC members and non-members, may speak in favor of or opposition against a proposal, but only ICC members can vote at the later Final Action Hearings. Proposals can also be withdrawn by the proponent at any time.

First Week-Long Training Course Dedicated to Hydrogen Storage
Karen Hall, National Hydrogen Association

The University of Applied Sciences in Ingolstadt, Bavaria, held a week-long training course from 25-29 September 2006, called STORHY Train-IN 2006. At the course, approximately 60 students from all over the world learned about state-of-the-art hydrogen storage, including pressure vessels, cryogenic storage, solid storage, safety aspects, and applications.

The course focused on automotive applications, and included demonstrations of model cars, including the award-winning Hyracer - the world’s smallest car running with a hydrogen combustion engine. It is a 1:8 scale model of the BMW record car H2R which set up numerous records for hydrogen-powered cars, including maximum speed (Guiness Book of World Record 2005). The Hyracer was developed at the University of Applied Sciences Ingolstadt by students and research assistants. Gaseous Hydrogen is stored pressurized in aluminum cylinders and runs a four stroke combustion engine. Challenges in the development were cooling the engine, an ignition system for the combustion process and meeting safety requirements. This model car demonstrates the next generation automotive technology on a small scale.

The course combined theoretical and practical experiences, brilliantly led by key staff from the University of Applied Sciences and augmented with over twenty guest presentations from industry leaders. The course was organized by Prochain e.V.

STORHY is an integrated project within the European Union Framework 6 Programme that relates to hydrogen storage systems for automotive applications.

StorHy - General Project Information
“Hydrogen Storage Systems for Automotive Application”

Coordinator: MAGNA STEYR Fahrzeugtechnik AG & Co KG
Time frame: 2004 – 2008 (4,5 years)
Official project start: March 1, 2004
Budget: € 18.7 m
EU contribution: € 10.7 m
34 partners from 13 European countries
(5 OEMs, 15 research institutes and 14 supplier companies)

And if that weren’t enough, the course included an active social program, providing opportunities to simultaneously enjoy the hospitality of Ingolstadt (as well as a visit to Munich for Octoberfest) and network with fellow students and presenters.

The course presented a viable model for hydrogen energy coursework that should undoubtedly be repeated.

Wake Up to Hydrogen: ICC Hearing Workshop Report
Patrick Serfass, National Hydrogen Association

During the Code Development Hearings for the International Code Council (HFCSR Aug 06HFCSR Oct 06), the National Hydrogen Association hosted two morning workshops focused on hydrogen education at the Disney Coronado Springs in Orlando, Florida, September 21-22, 2006.

At the early breakfast workshops, approximately 50 attendees (including code and permitting officials with some hydrogen industry professionals) engaged the speakers in questions and took the opportunity to examine the fuel cells and hydrogen storage devices. Jadoo had several of their metal hydride hydrogen canisters and fuel cells on hand for inspection. On both days, their N-Gen fuel cell operated the laptops during the workshop. Jadoo representatives also showed attendees examples of bonfire- and overpressure-tested metal hydride canisters to show that the containers maintain their structural integrity even when brought to failure.

Many different topics were covered during the workshop, but the main focus was on technical topics related to the hydrogen code proposals. The main technical topics addressed were:

  • Indoor fast-fill fueling (> 12 SCFM) today, mainly for fueling lift trucks, pallet trucks and other equipment in large warehouses
  • Above-ground Liquid Hydrogen Storage including diking, flash losses and liquid hydrogen’s inability to pool if spilled
  • Hydrogen Storage for Telecommunications including how hydrogen can be safely stored in cabinets near telecommunications equipment
  • Fueling Station Overpressure Protection which when located on a dispenser hooked up to a vehicle (one connected system) can provide an extra layer of safety to protect the vehicle’s hydrogen tank from being overfilled

A special thank you goes to Plug Power for sponsoring this event!

Presentations from the workshops, as available, are located below.
