National Hydrogen Association
March 31, 2008

2. Presenter Carl H. Rivkin, P.E. National Renewable Energy Laboratory
Project Leader for Hydrogen Codes and Standards

3. NFPA 2 Comprehensive hydrogen technologies code
Committee Scope: This committee shall have primary responsibility for documents on the storage, use, transfer, and generation of hydrogen. The use of hydrogen shall include, stationary, portable, and vehicular applications

4. NFPA 2
Will be composed primarily of material extracted from existing NFPA documents
New material must be submitted to source document and extracted into NFPA 2
NFPA 2 has authority to fill gaps

5. Timeline 2005 Hydrogen Technology Technical (HYD) Committee approved
2006 First HYD Meeting
2008 First draft of NFPA 2 available for public proposals
2010 NFPA 2 issued

6. Template Meant to compliment the ICC codes
Provide a level of detail between primary adopted Building and Fire codes and component level standards
Requirements in NFPA must not conflict with I Codes

7. Content Chapter 1 Administration Chapter 2 Referenced Publications
Chapter 3 Definitions
Chapter 4 Performance-Based Option
Chapter 5 General Requirements

8. Content Fundamentals chapter 5 sets base requirements
Use basic concepts such as threshold storage amounts and fire control area
Structure and terminology consistent with building and fire codes
Hydrogen generation equipment covered

Annex Material

15. Siting Separation distance tables developed in 1960s
No documentation of separation distance basis
Tables from 1974 edition of NFPA 50A and 50B became Table H-2 and H-4 in OSHA regulations

16. H-2

17. H-4

18. Siting
Task Group created with the inception of NFPA 2 project to validate or create new requirements
Process has moved forward effectively
Comment containing new gaseous hydrogen separation tables to be submitted to NFPA 55 and extracted back into NFPA 2

19. Siting
Next set of revisions would address liquefied hydrogen storage separation distance
Dispenser separation distances under scope of NFPA 52 would also be candidate for analysis
