Validation of Olfactory Assessment Methodology for 100% Hydrogen Network
Abstract
To ensure that the users and general public recognise and report hydrogen leaks without further education, current guidance states that the smell of hydrogen should be indistinguishable from that of natural gas. It is also expected that the same odourant will be used in hydrogen networks as is currently injected to natural gas and so it is essential to ensure that existing methodologies for olfactory assessment (Rhinology), originally developed for natural gas, are safe, effective, and applicable to 100% hydrogen environments.
