Chromacity, a laser manufacturer, has unveiled an innovative optical solution in partnership with Herriot Watt University and Frauhofer UK for detecting contaminants in renewable hydrogen. While renewable hydrogen is a vital player in decarbonizing the economy, ensuring its purity poses challenges. The collaboration has resulted in a novel approach that leverages high brightness, coherent Optical Parametric Oscillator (OPO) laser technology from Chromacity and advanced FTIR spectroscopy techniques. This solution offers substantial advantages over current methods by providing high spectral resolution and detection sensitivity. The new technology aligns with ISO 14687:2019 standards, which set thresholds for contaminants in hydrogen for fuel cells. Chromacity's CEO, Julian Hayes, emphasized that existing optical solutions often compromise on sensitivity or are overly complex and costly. In contrast, the Chromacity solution simplifies the process with a single light source, enabling efficient and cost-effective contaminant detection. The instrument's OPO laser's tunable bandwidth allows for the detection of various contaminants, including complex chemical signatures, in real-time. After successful lab tests on representative gas samples, the next phase involves implementing the system to enable real-time data utilization for enhancing the production process optimization. This breakthrough has the potential to revolutionize quality control in renewable hydrogen production, providing users with the confidence that the gas they use meets stringent quality standards without damaging critical components.
