HYDROGEN: THE 
FUTURE FUEL
z
Introduction
Hydrogen is an energy carrier that can transform our 
fossil-fuel dependent economy into a hydrogen 
economy, which can provide an emissions-free 
transportation fuel.

Hydrogen as a form of 
energy storage
The energy storage is one of the main challenges 
that the sector will face in the coming years. 
The battery technologies evolved a lot, but do not 
solve the issue of long‑term storage yet. It is this 
scenario where the hydrogen could be very useful.

Hydrogen in the 
transport sector
The transport sector is probably the area where the 
hydrogen might be imposed more effectively. 
The hydrogen fuel cell electric cars would reduce 
local air pollution because, like battery electric cars, 
they have zero emissions of polluting gases.

Hydrogen in the 
Industries
Hydrogen use today is dominated by industry, 
namely: oil refining, ammonia production, methanol 
production and steel production. 
Virtually all this hydrogen is supplied using fossil 
fuels, so there is significant potential for emissions 
reductions from clean hydrogen.

Hydrogen in the 
Infrastructure
In buildings, hydrogen could be blended into existing 
natural gas networks, with the highest potential in 
multifamily and commercial buildings, particularly in 
dense cities while longer-term prospects could 
include the direct use of hydrogen in hydrogen 
boilers or fuel cells.

Hydrogen in the Power 
Generation
In power generation, hydrogen is one of the leading 
options for storing renewable energy, and hydrogen 
and ammonia can be used in gas turbines to 
increase power system flexibility.

Practical opportunities 
Hydrogen is already widely used in some industries, 
but it has not yet realized its potential to support 
clean energy transitions. 
Ambitious, targeted and near-term action is needed 
to further overcome barriers and reduce costs.

Hydrogen can help tackle 
various critical energy 
challenges
It offers ways to decarbonize a range of sectors  
including long-haul transport, chemicals, and iron and 
steel  where it is proving difficult to meaningfully 
reduce emissions. 
It can also help improve air quality and strengthen 
energy security.

Hydrogen is versatile
A wide variety of fuels can produce hydrogen, 
including renewables, nuclear, natural gas, coal and 
oil. 
It can be transported as a gas by pipelines or in liquid 
form by ships, much like liquefied natural gas (LNG). 
It can be transformed into electricity and methane to 
power homes and feed industry, and into fuels for 
cars, trucks, ships and planes.

The Hydrogen Revolution
The green hydrogen is the fuel of the future. The 
ability to use a fuel with a zero CO2 footprint 
represents a revolution in the energy and 
transportation sector. 
The gasoline, the gas, the coal and all other fuels will 
be gradually displaced by hydrogen.
