Hydrogen - Gas Profile

Hydrogen (H2) is the first element in the periodic table. It is the most basic atom, consisting of a single proton in the nucleus orbited by a single electron. The lightest of the elements, hydrogen, is also the most abundant in the universe. At typical temperatures and pressures, hydrogen is a colourless, odourless, and tasteless gas. It's also extremely combustible, with an undetectable flame.


Because hydrogen is a highly flammable fuel, leaks represent a substantial fire risk. On the other hand, fires fueled by hydrogen are distinct from those fueled by other fuels. Heavy fuels and hydrocarbons, such as gasoline and diesel, pool near the soil when they spill. As it's one of the lightest elements on the planet, when a leak occurs, it immediately disperses upwards. Even though hydrogen is non-toxic, it can build up in enclosed locations such as battery storage rooms and cause asphyxiation by displacing oxygen. Additionally, hydrogen ignites and burns more rapidly than gasoline or diesel. If hydrogen is accessible, even an electrical spark from a human finger will suffice.
