Debunking myths about hydrogen Is it dangerous?


Are the hydrogen tanks of the Mirai safe?

In this article we tell you everything you need about the Toyota Mirai, the result of a project with more than 25 years of work behind it. This car is just the beginning for the Japanese firm, which imagines an emission-free society thanks to this endless element on earth. Toyota knows the reluctance of our society, full of fears and insecurities that soon go down in history as soon as we see the real possibilities. For example, it is very likely that when talking about the fuel cell and the hydrogen tanks installed in the Mirai, you think about the risks of an explosion, and so on with any means of transport that exists.

These tanks have been subjected to the most demanding tests, tests that involve firing by high caliber weapons, impacts, exposures to acid and very high temperatures. The vehicle itself has been reinforced with carbon fiber and, in the event of any collision, it will distribute the force evenly to avoid a greater risk to the deposit. In other words, not only is the container itself safe, but also the vehicle as a whole.

Comparisons are hateful but, in this case, they will help you understand the reason for the myth. Hydrogen has a very high degree of flammability and much lower risk of explosion to other fuels used, since becomes reactive between 18.3% and 59% concentration in air. Gasoline, for example, only needs 1% to explode. Furthermore, hydrogen is a gas that rises and disperses, while propane or gasoline fumes accumulate on the ground.
