  1. Hydrogen Safety in Transportation: Industry Perspective Christine Sloane International Conference on Hydrogen Safety Round Table Panel Discussion Pisa, Italy 7 – 10 September 2005

  2. Areas where standards for fuel cell vehicles differ from conventional electric vehicles • fuel cell stack (electrical isolation) • fuel handling system (leak) • fuel storage system (unintended release) • refueling vehicle-level crash performance standards vehicle-level crash performance standards system-level performance standards interface-to-infrastructure prescriptive standards Hydrogen Storage System Fuel Cell Power Module Hydrogen Fuel Handling System * Fuel Cell = rechargeable (refuelable) battery

  3. What do we want from Codes & Standards? -- to be ready in the 2010 – 2015 timeframe • Public safety • Commercial feasibility • Infrastructure compatibility • International consistency • Rapid entry of new technology Risk: premature & prescriptive standards slow advances Solution:performance standards

  4. Performance Standards Require demonstration of safe performance under cumulative extremes of potential use • design validation • manufacturing validation • (periodic or batch test) • same requirement regardless of materials used • same requirement regardless of method of construction • explicit linkage to extremes of potential use & exposure • Example: Vehicle Crash Test • vehicle hits barrier at specified speed & angle • required performance: • impact on passengers • fuel release

  5. ISO SAE UN ECE US-NHTSA EU nations FMVSS & UN GTR Regulations • Economy of scale = cost commercial feasibility • Focus on global design • = quality & less time Potential Rollout of FCV Standards & Rulemaking Demo Cars Can we do it? Pre-Commercial Is it viable? Production Concept Cars Is it real? # vehicles worldwide 100s 10s 1000s Critical mass Guidelines & Best Practices technology advances & evaluation Interim Specs Industry Standards validation & experience Rule Making
