“…fratyka et al, 2021). Leaks around natural gas infrastructure (Cho et al, 2022) should also be easily detectable, with even regional-scale enhancements exceeding 1.5 ppm around production sites (Caulton et al, 2014). Due to the low cost of these sensors, such leak detection sensor networks could provide an accessible method for identifying and correcting major fugitive emission sources.…”

“…High-resolution monitoring networks can aid in pollution mapping and source iden-tification -for example, in reducing leaks and fugitive emissions from fossil fuel production and distribution, one of the main anthropogenic sources of methane emissions (US EPA, 2017). Accordingly, researchers are investigating several options for lower-cost trace methane sensing with the goal of developing inexpensive sensor networks (Cho et al, 2022;Riddick et al, 2020a), low-cost drone-based solutions (Liu et al, 2021), and similar monitoring methods.…”

Abstract. Methane, a major contributor to climate change, is emitted by a variety of natural and anthropogenic sources. Commercially available lab-grade instruments for sensing trace methane are expensive, and previous efforts to develop inexpensive, field-deployable trace methane sensors have had mixed results. Industrial and commercial metal oxide (MOx) methane sensors, which are intended for leak detection and safety monitoring, can potentially be repurposed and adapted for low-concentration sensing. As an initial step towards developing a low-cost sensing system, we characterize the performance of five off-the-shelf MOx sensors for 2–10 ppm methane detection in a laboratory setting (Figaro Engineering TGS2600, TGS2602, TGS2611-C00, TGS2611-E00, and Henan Hanwei Electronics MQ4). We identify TGS2611-C00, TGS2611-E00, and MQ4 as promising for trace methane sensing but show that variations in ambient humidity and temperature pose a challenge for the sensors in this application.

Efforts to create a sustainable hydrogen economy are gaining momentum as governments all over the world are investing in hydrogen production, storage, distribution, and delivery technologies to develop a hydrogen infrastructure. This involves transporting hydrogen in gaseous or liquid form or using carrier gases such as methane, ammonia, or mixtures of methane and hydrogen. Hydrogen is a colorless, odorless gas and can easily leak into the atmosphere leading to economic loss and safety concerns. Therefore, deployment of robust low-cost sensors for various scenarios involving hydrogen is of paramount importance. Here, we review some recent developments in hydrogen sensors for applications such as leak detection, safety, and process monitoring in production, transport, and use scenarios. The status of methane and ammonia sensors is covered due to their important role in hydrogen production and transportation using existing natural gas and ammonia infrastructure. This review further provides an overview of existing commercial hydrogen sensors and also addresses the potential for hydrogen as an interferent gas for currently used sensors. This review can help developers and users make informed decisions about how to drive hydrogen sensor technology forward and to incorporate hydrogen sensors into the various hydrogen deployment projects in the coming decade.
