Example of hydrogen gas. 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. The area is located in the Brazilian craton in an. Unlike hydrogen it is highly non-reactive.

For example European countries such as the Netherlands and Germany are facing future electrification limits in end-use sectors that can be overcome with hydrogen. Hydrogen gas is being explored for use in combustion engines and fuel cell electric vehicles. For example hydrogen is non-toxic.

Under ordinary conditions hydrogen gas is a loose aggregation of hydrogen molecules each consisting of a pair of atoms a diatomic molecule H 2. It addition to that microwaves also penetrate the atmosphere. Due to its lightweight low cost hydrogen gas was used in the air balloons for flight.

Gas seepage in continental areas has been observed in circular topographical depressions of sometimes elongated shapes in which hydrogen gas concentration can be detected and quantified. Hydrogen fuel is hazardous because of the low ignition energy and high combustion energy of hydrogen and because it tends to leak easily from tanks. Hydrogen can also be used for seasonal energy storage.

But due to its explosiveness it is being replaced by helium. For example in the 2014 Toyota Mirai a full tank contains only 57 hydrogen the rest of the weight being the tank. Explosions at hydrogen filling stations have been reported.

The earliest known important chemical property of hydrogen is that it burns with oxygen to form water H 2 O. For example hydrogen is present in water practically all organic substances stars and interstellar gas galactic planets etc so it is difficult to overestimate the importance of this element in the world and the universe. Hydrogen sulfide gas is both flammable and colorless.
