Hydrogen is found in large quantities on Earth, can be used in many contexts and is being promoted as an important solution in the transition to climate-friendly energy. But hydrogen investment also generates heated debate. So what’s the deal with hydrogen?
As much as 90 per cent of all atoms in the universe are hydrogen atoms. Hydrogen is the lightest, smallest and most common of all the elements. It has the atomic number one in the periodic table.
Hydrogen is also plentiful on Earth, where a lot of the hydrogen is bound in water. The water molecule consists of two hydrogen atoms and one oxygen atom (H2O).
In the Earth’s crust, every sixth to seventh atom is a hydrogen atom. Most hydrogen atoms are chemically bound together with other atoms, including in gas, petroleum, proteins, carbohydrates and fat.
Pure hydrogen therefore needs to be produced, or extracted, from hydrogen-containing raw materials such as gas or water.
Hydrogen has versatile properties and can potentially be used in many ways, including as a replacement for fossil energy sources like oil and coal.
Hydrogen is considered one of the main factors, or drivers, in the green shift.
Hydrogen’s role in the energy transition is seen as a clean and climate-friendly alternative to fossil fuels in heat and electricity production. Due to its versatility, hydrogen can also replace fossil fuels in industrial processes, such as coal in the steel industry. It can be used as fuel in the transport sector, in particular shipping and aviation.
