NFPA 2 NFPAs Comprehensive Hydrogen Technologies Code National

NFPA 2 NFPA’s Comprehensive Hydrogen Technologies Code National Hydrogen Association March 31, 2008

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

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

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

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

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

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

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

Content

Content • Chapter 6 General Gaseous Hydrogen (GH 2)Requirements for Vehicular Applications • Chapter 7 Gaseous Hydrogen Compression, Gas Processing, Storage, and Dispensing Systems for Vehicular Applications

Content • Chapter 8 Liquefied Hydrogen (LH 2)Fueling Facilities for Vehicular Applications • Mixed fuel installations will be integrated across these vehicular requirements

Content • Chapter 9 Stationary Fuel Cell Power Systems • General Equipment Configuration for Fuel Cell Power Systems • Siting and Interconnections for Fuel Cell Power Systems

Content • Fuel Supplies and Storage Arrangements for Fuel Cell Power Systems • Ventilation and Exhaust for Fuel Cell Power Systems • Fire Protection for Fuel Cell Power Systems • Fuel Cell Power Systems 50 k. W or less

Content • Chapter 11 Combustion processes (furnaces and ovens) • Chapter 12 Special Atmospheres • Chapter 13 Laboratory operations/research • Annex Material

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

H-2

H-4

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

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
