Hydrogen is the lightest and most abundant element in the universe, it contains unique properties, and is one of the most important elements in science. It is a colorless, odorless, tasteless gas. It has several important uses in industries such as fuel cell production and fertilizer manufacturing, but is also commonly used as an energy source for powering things like rockets and vehicles.

Hydrogen is one of the most abundant elements in the universe, but it can also be produced on Earth through several different processes. The two primary methods used to produce hydrogen are steam methane reforming and electrolysis.
Steam Methane Reforming (SMR) involves heating natural gas with high-pressure steam in the presence of a catalyst, usually nickel. This breaks apart the hydrocarbons, forming a mix of carbon dioxide and hydrogen called synthesis gas or syngas.
Electrolysis is a chemical process that splits water into oxygen and hydrogen by passing an electric current through the water. A key component in electrolysis is an electrolyzer, which is an electrically powered device that uses energy to separate the components in water (hydrogen and oxygen). In addition to being clean and renewable, electrolysis also produces hydrogen quickly and efficiently.

Hydrogen has become an increasingly important energy source due to its abundance and versatility. It can be used for a variety of purposes, such as fuel for transportation, heating homes, producing electricity, to produce chemicals for industrial purposes, and even generating clean water. In its most basic form, hydrogen can also be used to store energy for later use. In the near future, hydrogen fuel cells could be used to power vehicles with zero emissions.

Hydrogen is considered to be a relatively safe energy source when used properly and safely. While hydrogen is flammable, it does not release harmful emissions into the atmosphere like fossil fuels do. When used in a well-designed system, hydrogen fuel can provide a clean and efficient energy source with minimal risk.

Hydrogen is key to decarbonisation because it has the potential to help the world transition away from a dependence on fossil fuels. Hydrogen can be used as an energy source for transportation, electricity generation, and heating in place of oil, gas, and coal. By using hydrogen instead of traditional fossil fuels, emissions of greenhouse gases can be drastically reduced or eliminated.
Not only does hydrogen have the potential to replace current sources of carbon-emitting energy, but it can also be produced from renewable resources like wind and solar power. When renewable energy is used to create hydrogen fuel through electrolysis, this creates what is known as “green” hydrogen—a zero-emission form of fuel that can significantly reduce our dependence on fossil fuels and cut down global carbon emissions. This is why hydrogen is such a key component of the decarbonisation effort.
