Is hydrogen more dangerous than the other gases?

It is true that hydrogen’s flammability is higher than that of gas or oil. Nevertheless, the risk of a hydrogen layer forming is much lower due to its volatility. In fact it is diluted much more quickly in the air: 4 times faster than natural gas and 12 times faster than petrol fumes, according to Ifpen.

The risks associated with hydrogen are therefore different from those associated with other fuels. That is why actors in the industry are working to adapt infrastructures and technologies to suit hydrogen’s specific characteristics. At Teréga, study projects are currently under way, looking at the potential for injecting hydrogen into our transport grid and storage facilities.
