Hydrogen Cars Vs Electric Cars: Which Is More Sustainable?
                     HYDROGEN CARS VS ELECTRIC CARS: 
WHICH IS MORE SUSTAINABLE?
WHAT IS AN ELECTRIC 
CAR?
Electric cars are relatively simple machines 
in principle. Mains electricity is stored as 
chemical energy in a battery, before being 
converted back into electrical energy by the 
car’s power systems, with this electrical 
energy used to power a motor or motors 
that turns the car’s wheels.

WHAT IS A HYDROGEN 
CAR?
Hydrogen cars are far more complex than 
EVs. Hydrogen is pumped into a car’s tank 
and stored at very high pressure, as 
hydrogen is far less energy dense than 
petrol/diesel so must be compressed to get 
enough of the stuff on-board.

PROS OF HYDROGEN AND 
ELECTRIC CARS
ELECTRIC CARS
The infrastructure for electric cars is more 
advanced than that for hydrogen-powered 
vehicles. Governments around the world 
have been investing in infrastructure such 
as charging stations at existing petrol 
stations and motorway rest stops, shopping 
centre car parks and even on the side of 
some streets.

CHEAPER
Electric vehicles are also cheaper than 
hydrogen powered cars, while the cost of 
recharging is also less during off-peak grid 
times, making electric vehicles a good long-
term investment.

HYDROGEN CARS
Hydrogen cars provide many similar benefits 
as electric cars, including the all-important 
lack of polluting emissions.

RENEWABLE FUEL
While the process to produce hydrogen gas 
can be complex, it is the most abundant 
element in the universe, meaning that 
hydrogen is a renewable fuel source.

CONS OF HYDROGEN AND 
ELECTRIC CARS
RANGE
With electric cars, the range is highly 
dependent on which vehicle you buy. 
Hydrogen fuel cell vehicles offer greater 
ranges and faster refueling times too.

CHARGING/REFUELING 
STATION AVAILABILITY
Hydrogen fuel cell cars are not only more 
expensive than many electric cars, they are 
also have much less infrastructure when it 
comes to refuelling, with only around 400 
hydrogen refuelling stations currently in the 
world (including private ones).

SAFETY
Safety has been seen as a key concern for 
hydrogen fuel cells, due to the highly 
flammable nature of hydrogen gas, which 
burns in air at concentrations ranging from 4 
to 75%.
Electric batteries also come with their safety 
concerns and challenges. If lithium-ion 
batteries are allows to overheat or overcharge 
they can cause injury.
