HYDROGEN 
AND IT’S 
IMPORTANCE
Introduction
• One of the major goals today is decarbonizing the planet and the countries around the 
world have set the target as 2050. 
• One of the major actions to be taken in this regard would be to decarbonize the production 
of hydrogen

What is Green Hydrogen?
• The technology for green hydrogen is based on the generation of hydrogen through 
electrolysis. It is a universal, light and highly reactive fuel.
• In case the electricity is produced through renewable sources of energy, the hydrogen 
would be green hydrogen.

What does IEA say?
• IEA informs that through the method of obtaining green hydrogen countries would save 
830 million tonnes of Carbon dioxide that is emitted annually by using fossil fuels.

High production cost
• However, there are some questions about the viability of green hydrogen because of its 
high production cost; reasonable doubts that will disappear as the decarbonisation of the 
earth progresses and, consequently, the generation of renewable energy becomes cheaper.

Why Hydrogen can be used for clean energy?
• Hydrogen is the most abundant element on earth. Also, the global demand for hydrogen as 
a fuel has become thrice of what it was in 1975. 
• It is also the only source of energy that only emits water vapour and leaves no residue in 
the air.

Green Hydrogen: Advantages
• Hydrogen is a 100 % sustainable source: Green hydrogen does not emit polluting gases in 
its combustion or production processes.
• Green Hydrogen is a gas and thus would be easily stored. It can be subsequently used for 
other purposes just following its production.

Green Hydrogen: Advantages Cont.
• It can be easily transformed into electricity or synthetic gas which can then be used for 
domestic, commercial, industrial purposes.
• Green hydrogen can be mixed with the natural gas, up to a maximum of 20 %. It can also 
be transported through the same pipes and in the same infrastructure.

Green Hydrogen: Disadvantages
• Renewable sources, which would be used to generate green hydrogen through electrolysis, 
are extremely expensive currently taking the cost of the whole production to sky heights. 
• The production of green hydrogen requires more energy than other fuels.

Importance of Green Hydrogen
• Green hydrogen can be used to provide water to the crew members in space stations.
• Energy storage- Compressed hydrogen tanks can store the energy longer and are easier to 
handle than lithium-ion batteries as they are lighter.

Importance of Green Hydrogen Cont.
• Electricity and drinking water generation, energy storage, transportation etc. 
• Transport and mobility- Hydrogen can be used in heavy transport, aviation and maritime 
transport.
