NFPA Hydrogen Technologies Technical Committee Meets at NREL
Paul May, NFPA Staff Liaison
On June 26-27, 2008 the NFPA Technical Committee on Hydrogen Technologies met at the National Renewable Energy Laboratory in Golden, Colorado. This was the third meeting for this new committee that will create NFPA 2. The committee continued their work to develop a draft document towards a final document for public review.
Below is an overall schedule for the T/C on NFPA 2 Based on the NFPA Standards Council decision to place the document on the Annual 2010 revision cycle:

The Task Groups presented their results to the entire Technical Committee and guests.
Separation Distances: Jeff LaChance of Sandia National Laboratories gave a presentation on risk-informed approach. Larry Fluer of Fluer, Inc. gave a presentation on the separation distance table of NFPA 55. Three members of HIPOC, as well as several other guests, were there for the discussion.
Task Group leaders from each of the other Task Groups also presented their work, and made recommendartions concerning the future of the task group.
Steps towards the Report on Proposals (ROP) stage were discussed and task group assignments brought forth. Several New Task Groups were formed as follows:
Task Group 7 Integration. This task group is responsible for ensuring consistent format throughout the text and ensure all the chapters flow properly from the fundamental chapters (1-8). This entails pulling together the input from Task Groups 2, 3, 4, 5, &6 into a draft document that will serve as the first draft NFPA 2 code for TC review.
Task Group 8 Quality Control. To provide a comprehensive review of each iteration of the NFPA 2 document as prepared for publication by the NFPA 2 Integration Task Group. This work will include the identification and coordination of resolution of all concerns with the Integration Task Group in a timely manner. The reviews will address technical content, prose and formatting.
Task Group 9 Liquid Hydrogen. This task group would evaluate existing codes relative to LH2 and address the short-term (A2010) and long-term (beyond A2010) gap analysis for inclusion into NFPA 2 and other standards. Focus will be on differences between liquid hydrogen (LH2) and gaseous hydrogen (GH2) that would necessitate additions and updates to NFPA 2. Use of LH2 would be limited to small-scale generation (for consideration as a reserved chapter) and include storage, loading, unloading, vaporization, and dispensing as GH2 and LH2 at points of use. Responsibilities could include dialogue with the research community, identification of differences w risk implications, definition and development of tables and text.
Task Group 10 Hydrogen Explosions. To develop scientifically-based and practical H2 explosion prevention and mitigation measures for inclusion in NFPA 2 and other NFPA documents as appropriate. Assess the impact of code provisions proposed for NFPA 2 and existing provisions in applicable NFPA codes and standards (ie. 52/55/853/45/68/69/86/88A/502/et al.##s) related to the risk of hydrogen explosions.
Disbanding of Old Task Groups. The following Task Groups were disbanded effective as of the June meeting and the follow on tasks for the other task groups are listed below:
Task Group 1 disbanded. The function of this TG has been superceded with new TG7.
Task Group 2 – Fundamentals This task group has completed its work product and is disbanded.
Task Group 3 Vehicular This task group effort will be complete when the final ROC text for NFPA 52 is available and extracted into NFPA 2.
Task Group 4 Fuel cells and generation This task group effort will be complete when the final ROC text for NFPA 853 and 55 is available and extracted into NFPA 2.
Task Group 5 Stationary Applications This task group is complete and is now disbanded. Thanks for the good work.
Task Group 6 Separation Distances The work product of this task group was incorporated into the draft NFPA 2 by Task Group 2. There is ongoing work for this task group in the area of developing separation distances for liquid hydrogen and developing the mitigation credits concept.
The next meeting will be hosted by TC member Al Unione at the National Engineering Technologies Lab (NETL) in Pittsburgh, PA February 24-26, 2009. The next meeting will be an ROP meeting.
