Hydrogen gas sensor based on SnO2-Pd based nanomaterials

Hydrogen exists naturally in the environment in low levels. Australia’s environment is harsh and remote so we aim to create a hydrogen sensor that will accurately and dependably detect hydrogen gas down to ppb levels for these conditions.

The Problem

The recent publications of various hydrogen (H2) exploration research groups worldwide have highlighted the difficulties in reliably measuring and monitoring the minute amount of H2 in the natural environment. These research groups employed ENGIE corporation’s electrochemical sensors, which are state-of-the-art and designed for generic gas monitoring purposes, both organic and inorganic. This research project’s primary aim is to create a dependable H2 sensor that can monitor the low levels of H2 from natural seeps.

Our solution

Our proposal is to create an H2 gas safety sensor that utilizes SnO2-Pd nanomaterials to monitor natural hydrogen seeps. This sensing approach has the potential to modernize both environmental monitoring and the hydrogen exploration industry. By utilizing this sensing approach, we can achieve greater sensitivity and resolution in monitoring the hydrogen flux above natural seeps, thereby increasing our knowledge of natural hydrogen systems. However, it’s crucial to note that adopting hydrogen sensing technologies to suit the unique Australian conditions is essential, including harsh environmental conditions and remote locations.

Collaborators

We intend to collaborate with CSIRO Manufacturing BU in Clayton and Solar Division at Newcastle to fabricate and instrument the sensor. Additionally, we would like to collaborate with ANFF and CSIRO Manufacturing BU for the analysis and characterization of the sensor.
