Hydrogen Fueling Standardization- Enabling FCEVs with Fast Fueling and Consistent Vehicle Range Equal to Today

Abstract

Hydrogen Fueling Standardization: Enabling ZEVs with "Same as Today" Fueling and FCEV Range Zero Emission vehicles are essential to reduce the greenhouse gas emissions in the transportation sector. Wide scale adoption of electric vehicles has been challenging due to the limited range and long charging times. Fueling with hydrogen offers the possibility to fuel Fuel Cell Electric vehicles in a few minutes and allow them to achieve a consistent high SOC, enabling 300+ mile range. Hydrogen Vehicles are slated to first enter into a small-scale commercial phase in three markets (Germany, California, and Japan) with the advent of multiple OEMs 2015-2017. SAE created a fueling protocol to standardize this fueling worldwide base on modeling, lab and real-world data. The objective of the SAE J2601 hydrogen fueling protocol is to fuel all FCEV vehicles within a reasonable timeframe, with a high fueling density, without exceeding the hydrogen safety storage limits. SAE J2601 creates a "Customer Acceptable" hydrogen fueling, with rapid hydrogen Fueling (<5 minutes) at 70MPa and 35MPa utilizing pre-cooling of hydrogen to offset the heat of compression. SAE J2799 Communications fueling is also possible enabling close to 100% rated density or state of charge (SOC). After 13 years of development, the J2601 and J2799 standards, published in 2014 will enable the first generation of commercial fuel cell vehicle and hydrogen fueling infrastructure which enables the "same as today" fueling experience and vehicle range.
