H2FIRST Hydrogen Contaminant Detector Task: Requirements Document And Market Survey

This H2FIRST project report, published in April 2015, describes the current commercial state of the art in contamination detection and identifies the technical requirements for implementing a hydrogen contaminant detector (HCD) at a station. The rollout of hydrogen fueling stations, and the fuel cell electric vehicles they support, requires the assurance of high quality hydrogen at the dispensing point. An HCD, 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 report presents near term engineering requirements for an HCD at a station, describes the results of a market survey of currently available gas analysis technologies, and identifies the gaps between what is currently available and what is required.
