Towards Hydrogen!
Discover the potential of hydrogen for the energy transition.
Why hydrogen?
Hydrogen... everybody's talking about it, and for a good reason! With hydrogen, energy transition is accelerating.
Till today hydrogen has been mostly used to make ammonia for the fertilizer industry and to refine petroleum products, including desulfurizing fuels. Hydrogen is also used to manufacture electronic components and for rocket propulsion.
But with energy transition, new hydrogen applications are being developed.
Reducing CO2 emissions of the most carbon-intensive industries, developing sustainable transport... When produced from renewable resources, hydrogen can tackle the carbon emissions of industry and intensive transport, which are responsible for 45% of the planet's CO2 emissions. Decarbonized hydrogen could thus play a decisive role in the fight against climate change.

Hydrogen: what role in the energy transition?
Reinventing manufacturing
Decarbonization of the industry is essential to the construction of a low-carbon society. That is where hydrogen can make a real difference. Used as a feedstock or an energy vector, renewable and low-carbon hydrogen can help to significantly reduce CO2 emissions in hard-to-abate industries: oil refining, steel production, electronics, glassmaking, chemicals.
Traveling differently
From trucks to trains, heavy-duty mobility, ships and planes, transportation accounts for about 23% of CO2 emissions. Is there a realistic, sustainable solution? Will hydrogen cars replace electric cars? No, but hydrogen can help where electrification doesn’t fit. It is now identified as a low-carbon energy vector by fleet operators, shipbuilders, aircraft and truck manufacturers. Among its advantages are providing shorter refueling time and achieving longer distances.
“Hydrogen is now part of our daily lives and will become an even greater part of those of future generations. Its rapid and joint development on a global scale is a cornerstone of an effective energy transition.

What is hydrogen?
By selecting one of the radio buttons, you will be redirected to the next question.False!
Just like iron and copper, hydrogen is one of the 118 natural elements that are known to make up the universe. It is almost always combined with other elements and is practically omnipresent, starting with water or H2O. Lastly, hydrogen is the most abundant molecule in the universe: another important feature that speaks volumes about its potential!

Is hydrogen a kind of energy?
By selecting one of the radio buttons, you will be redirected to the next question.Yes, it’s as simple as that!
Not quite…
Unlike an energy source that exists in its natural state (the sun, the wind, etc.), hydrogen is an energy carrier.
Hydrogen can be used to store and transport energy, which is particularly useful when it comes to the transition from a primary energy (found in nature) to final energy (delivered to the consumer).
This means that we need an energy source in order to produce it. That’s why hydrogen is also described as a secondary energy: it’s produced by the transformation of a primary energy. It’s just like electricity.

How is hydrogen produced?
By selecting one of the radio buttons, you will be redirected to the next question.False!
Hydrogen is produced either by water electrolysis or from methane or biomethane by steam reforming or autothermal reforming processes with capture of the emitted CO2.
Hydrogen has historically been produced from fossil fuels... Its future will be resolutely low-carbon and renewable! Our objective is to convert all our carbon-based hydrogen production methods to low-carbon methods as quickly as possible.

What happens to the CO2 captured during hydrogen production?
By selecting one of the radio buttons, you will be redirected to the next question.False!
CO2 can be used in different forms by many industries.
80% of the CO2 sold by Air Liquide is used in the food industry for the carbonation of fizzy drinks and water, to cool, freeze or extend the shelf life of foodstuffs and to stimulate plant growth in greenhouses.
The remaining 20% is used in other industries for various purposes: to enhance the recovery of crude oil from oil deposits, for welding and to protect welding joints from oxidation, as a solvent for industrial cleaning, to calibrate aeronautical and automotive equipment, as a cooling agent in electronics, as a reactive agent in the pharmaceutical industry, for certain medical procedures (laparoscopies, colonoscopies, etc.), for wastewater treatment and in the cement industry.
