H2FIRST Hydrogen Contaminant Detector Task: Requirements Document and Market Survey

Daniel Terlip, William Buttner, Scott McWhorter

Research output: NRELTechnical Report


H2FIRST is a DOE project that supports the goals and objectives of H2USA by addressing the near and mid-term technology challenges related to hydrogen fueling stations. The hydrogen fuel standard, SAE J2719 2011, specifies that fuel dispensed to fuel cell electric vehicles must be at least 99.97% pure and includes further in the hydrogen pathway from production to dispensing. A hydrogen contaminant detector, defined as a combination of a gas analyzer and the components necessary for fuel stream integration, installed at hydrogen stations is one method for preventing poor quality gas from reaching a fuel cell electric vehicle. This document identifies the characteristics required of such a device by industry and compares those requirements with the current state of commercially available gas analysis technology.
