    1. 1. SAE TIR J2601/2 Hydrogen Transit Bus Fueling #201 Nico Bouwkamp, Technology Analyst California Fuel Cell Partnership (nbouwkamp@cafcp.org) Context Preliminary fueling rates Globally, over 80 hydrogen fuel cell transit buses are operational in daily public revenue service, with more planned for operation. These buses are fueled daily with up to 40 kilograms of H35 . Currently, no published standard for fueling these buses that establishes safety limits or performance requirements is in place.  Option A – Fast Fueling For fast fueling of buses, up to 7.2 kilograms per minute or 120 grams per second  Option B – Normal Fueling For normal fueling of buses, up to 3.6 kilograms per minute or 60 grams per second  Option C – Slow Fueling Scope The scope of this effort is to provide boundary performance requirements for dispensing systems used for fueling 35 MPa heavy duty hydrogen transit buses. These can be used as guidance to those building fueling systems and hydrogen fuel cell buses, and transit bus operators. For slow fueling of buses, up to 1.8 kilograms per minute or 30 grams per second Figure 2: Operating window for pressure and temperature Boundary conditions (Figure 2) Communication for fueling  In-advance communication Application  Heavy duty hydrogen transit buses with a tank storage capacity >10 kilograms of 35 MPa hydrogen  Fueling buses to a full fill or ≤100% State of Charge between bus OEM and station implementer  Active communication between station & vehicle, using SAE J2799 or J1939  Bulk hydrogen gas T within vehicle fuel tanks: ≤ 85°C  T fuel at dispenser nozzle: ≥ - 40°C  State of charge ≤ 100% Recommended actions Project participants SAE TIR J2601/2 task force participants Figure 1: AC Transit fueling station (Photo courtesy of L. Eudy, NREL)  Max P within vehicle tank system: 125% NWP  Implement a verification process for faulty tank valves Figure 3: SunLine FCEB Figure 4: AC Transit FCEB
