Basics

A Chemical used to add a scent to various Compressed Gasses (Typically Methane or Propane / LPG )
Thus when there is a leak one can detect the smell and respond accordingly
Various Compounds Are Used, but the main ones are:
- Methanethiol (Common in Methane (aka "Natural Gas" ; CNG ) )
- Ethanethiol (Common in Propane / LPG )
  - The Following can also be used (or blended with eachother and/or the odorants listed above)
    - Dimethyl Sulfide
    - Isopropyl Mercaptan (aka Isopropanethiol )
    - Methyl Ethyl Sulfide
    - Normal Propyl Mercaptan (aka Propanethiol )
    - Secondary Butyl Mercaptan (aka 2-Butanethiol )
    - Tertiary Butyl Mercaptan (aka tert-Butylthiol )
    - Tetrahydrothiophene

Main advantage is the lack of Sulfur Dioxide emissions, thus no Sulfur Pollution / Acid Rain Risks
Also thus makes propane EVEN CLEANER burning
Main downsides are cost/low TRL
- Also may mot be widely known by the community/may smell different
May have less Odorant Fade issues
Granted CITATION NEEDED, but may be less harmful to health (Especially chronic exposure from Warehouse Forklifts or at a Filling Station etc)

Currently the “GreenOdor Project” ; uncertain on Technology Readiness Level
As stated in a Stock Shareholder Presentation, “aiming to prevent 40 tons of sulfur emission per year”
