Abstract Scope |
Methane leaks from natural gas infrastructure represent a significant challenge in combating climate change. There is a need to develop low-cost, robust, and field deployable sensor systems to monitor the nation’s natural gas infrastructure for leaks. These requirements are met by the use of mixed potential electrochemical sensors (MPES). MPES are solid-state electrochemical devices where differences in catalytic activity between the electrodes produce a sensor response to an analyte gas. Additive manufacturing methods enable the prototyping of materials and geometries for these devices at low cost and with rapid iteration times. Syringe extrusion was used to deposit zirconia substrates, metal and metal oxide electrodes, and porous solid-state electrolytes. Sensor responses to simulants of methane emissions from natural gas, bovines, and wetlands were collected. Finally, integration of the printed sensors with portable readout and transmission hardware was demonstrated.
