Question

smell of hydrogen gas​

Answer 1

Answer:

Neither hydrogen nor natural gas smell in their normal state. Natural gas supplied via gas mains has a special odorant added to it to give it its characteristic smell, so that leaks can be detected. Adding some hydrogen to natural gas may dilute the smell, but will not change its effectiveness.

Answer 2

Neither hydrogen nor natural gas smell in their normal state. Natural gas supplied via gas mains has a special odorant added to it to give it its characteristic smell, so that leaks can be detected. Adding some hydrogen to natural gas may dilute the smell, but will not change its effectiveness. If required, additional odorant will be added to compensate for this. Tests will be carried out on the Keele network to ensure the required levels are maintained through the trial.
