Can hydrogen be made safe?

A number of hydrogen’s properties make it safer to handle and use than the fuels commonly used today. For example, hydrogen is non-toxic. Specifically, hydrogen has a wide range of flammable concentrations in air and lower ignition energy than gasoline or natural gas, which means it can ignite more easily.

Are hydrogen engines dangerous?

The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.
