Alternative fuel sources, such as hydrogen-enriched natural gas (HENG), are highly sought after by
governments globally for lowering carbon emissions. Consequently, the recognition of hydrogen as a
valuable zero-emission energy carrier has increased, resulting in many countries attempting to enrich
natural gas with hydrogen; however, there are rising concerns over the safe use, storage, and transport of
H2 due to its characteristics such as flammability, combustion, and explosivity at low concentrations (4 vol
%), requiring highly sensitive and selective sensors for safety monitoring. Our framework detects
concentrations of simulated HENG based on time-series data collected from a patent-pending microfluidicbased
detector. We have also developed machine learning models for predicting the presence and
concentration of NG odorants from the same sensor data. Furthermore, our team is exploring the
integration of these sensors with technically reliable membranes that can be used for HENG purification or
extraction for onshore or offshore applications.
