J2601/3 - Fueling Protocol for Gaseous Hydrogen Powered Industrial Trucks

Details Not available for purchase at this time. Document Number: J2601/3 Project Initiation: 03-07-2011 Sponsor Name: Robert W. Boyd Title Fueling Protocol for Gaseous Hydrogen Powered Industrial Trucks Scope This document provides performance requirements for fueling vehicles including a pressure test method to check for leaks, pressure limits for the vehicle fueling system and target pressure compensation limits to manage the effects of vehicle tank temperature rise during the fueling process. Three fueling options for fueling are available for the dispenser provider: (1) slow flow to service pressure only, (2) a simple fixed orifice flow control system intended to provide 85 to 95% SOC fills at a nominal 500 to 1000 grams per minute fueling rate and (3) a formula based end of fill protocol based on the Honda MC method of calculating vehicle end temperature and target fill pressure. These fueling methods do not require electronic communications between the vehicle and the dispenser. All three dispensing protocols result in similar fueling performance from the vehicle perspective. These fuelling protocols are suitable for tanks as small as 20 liter water volume, tanks as large as practical, and may be used for fueling stationary hydrogen storage as well as vehicle tank fueling systems. The intent of this document is to: (A) to allow the deployment of simple but safe and effective dispenser system for HPIT and stationary hydrogen storage system fueling and (B) enable the advanced user of the document to be able to characterize vehicle fueling systems with an distinct MC number and then be able to fit the range of captive fleet based vehicles into common fuel dispensing protocol with a higher target SOC than achievable with the simpler systems
