Combined Gasoline/Hydrogen Fuel Station Opens
Gasoline vapors are heavier than air and can creep along the ground. That makes gasoline more dangerous than hydrogen. An outdoor tank of gasoline is more dangerous than an outdoor tank of hydrogen. Burying a tank of gasoline has the additional risk of contaminating groundwater and soil.
The Hindenburg burned because the fabric skin was doped with a mixture of Aluminum and organic compounds (cellulose acetate butyrate). It burned first and fastest.
Please don't try to sabotage the Hydrogen economy by buying into and propagating fearmongering that is ignorant of basic science.
