Is hydrogen safe?

Hydrogen, like all other fuels, is flammable like natural gas and petrol. Therefore, it must be handled safely. The concrete properties of hydrogen are:

• Low ignition energy;
• Flammable in a wide range: 4-75% (compared to gasoline: 1,3% - 7,1%);
• Very light, 14x lighter than air, allowing easy evacuation of the gas;
• Very low energy density at atmospheric pressure.

The main safety measures taken for hydrogen equipment are for high pressure. All components are tested and certified with a very high safety margin. At atmospheric pressure and temperature, the fuel is a lot safer than other fuels like gasoline, LPG or natural gas.
