Hydrogen fuel is emerging as a key player in the rapidly growing clean energy market. However, hydrogen can contain impurities (introduced during production, purification and along the hydrogen supply chain) that limit the efficiency of fuel cells and lead to concerns over pollution. Markes International’s Multi-Gas thermal desorption systems offer on-line and off-line identification and quantitation of a wide range of these compounds of concern. This application note shows the robust, reproducible analysis of trace volatile organic compounds (VOCs), including aldehydes (i.e., formaldehyde), hydrocarbons, and halogenated and sulfurcontaining compounds (i.e., hydrogen sulfide), by thermal desorption–gas chromatography–mass spectrometry/sulfur chemiluminescence detection (TD–GC–MS/SCD). Detection limits down to low ppt levels were achieved in accordance with standard methods (ISO 14687, EN 17124, ISO 21087, GB/T 37244 and ASTM D78921–5 and SAE J2719).
Transportation is responsible for one-third of carbon dioxide emissions into the atmosphere, which can contribute to a variety of health effects.6 Hydrogen is an emerging renewable energy source that could enable a move away from fossil fuels and carbon-based energy. It is anticipated that widespread adoption of hydrogen fuel will limit dependency on fossil fuels, reducing air pollution and greenhouse gas emissions.7 Cars and other hydrogen-fuel-cell-powered vehicles could offer clean, carbon-neutral transportation.
