Development and Validation Testing of Hydrogen Fast-Fill Fueling Algorithms

摘要

The rapid filling of a compressed hydrogen (H2) gas cylinder results in a temperature risewithin the cylinder due to heat of compression effects. Without compensation, this effectresults in reduced density and lessened vehicle range. In recognition, hydrogen gas storagecontainer standards allow containers to be pressurized such that, when the stored gastemperature stabilizes, a complete fill is achieved based on prevailing ambient conditions.Fast fill hydrogen dispensers need to control the fill process so that safety is ensured andcomplete fills are achieved over a wide variety of ambient and vehicle conditions.Under a cost-shared program with the U.S. Department of Energy (USDOE), GasTechnology Institute (GTI) is developing a H2 fast-fill fueling methodology and associateddispenser and control system for accurately filling hydrogen cylinders. This paper describesthe development and testing of a H2 fast-fill fueling dispenser control algorithm.
