The Importance and Potential of Hydrogen as an Element
TLDR Hydrogen, the most abundant element in the universe, has a wide range of applications including being a key component in the formation of stars, a potential fuel source for cars and airplanes, and a possible solution for creating electricity in fusion reactors. However, engineering challenges need to be overcome for hydrogen to be used regularly in everyday life.
Timestamped Summary
00:00
Hydrogen is a substance that makes up 98% of the observable matter in the universe, is inside your body, and is the lightest and most fundamental element.
02:29
Hydrogen is the simplest and most abundant element in the universe, making up 98% of all baryonic matter, and is the key component in the formation of stars.
04:15
Hydrogen is a very light element that tends to bind with itself to form H2, and while it is the most common element in the universe, it is only present in minuscule amounts in our atmosphere.
06:03
Hydrogen was first discovered to be produced from water with electricity, and its initial use case was taking advantage of its light weight and buoyancy for air travel.
07:38
Hydrogen is used in the process of hydrogenation, making hydrocarbons, and has been discussed as a potential fuel source for cars and airplanes, with fuel cells being a more efficient method of creating electricity from hydrogen.
09:12
The engineering problems associated with handling hydrogen, including its energy density and difficulty in handling as a gas or liquid, have scaled back the talk of creating a hydrogen-based economy, although it still has potential as a fuel in a fusion reactor.
10:53
Hydrogen can be produced by connecting wires to a battery in water or by mixing vinegar with baking soda, and although it is not commonly experienced in daily life, it has the potential to be used regularly if engineering challenges are overcome.
