No it is not. In fact, it is safer. Here are some hydrogen gas safety issues operators need to be aware of:. The fuel storage tanks used in cars and buses are extremely robust, especially when compared with vehicle gas tanks, which are typically made of plastic. At some point over its service life, any fuel cell system could develop a leak. This could happen because of a vehicle collision, poor maintenance, or age.
But if it happens—what then? Ballard fuel cell power modules are designed with passenger and operator safety in mind. A couple of examples:. So is hydrogen explosive? As with any fuel, hydrogen must be treated with respect and care. Hydrogen is a very light gas. There are no known odorants that can be added to hydrogen that are light enough to diffuse at the same rate as hydrogen.
In other words, by the time a worker smells an odorant, the hydrogen concentrations might have already exceeded its lower flammability limit. Elliot Walsh holds a B. S in Cell and Developmental Biology and a B.

Hydrogen is also highly flammable and will easily combust or explode even at low concentrations. Use as a coolant Welding applications Previous use in air balloons and airships.

For example, hydrogen is non-toxic. In addition, because hydrogen is much lighter than air, it dissipates rapidly when it is released, allowing for relatively rapid dispersal of the fuel in case of a leak. Some of hydrogen's properties require additional engineering controls to enable its safe use.
