Why hydrogen fuel cells cars are better then the hydrogen combustion cars. “Are they the really the renewable future we where promised ?”

We all know the fact when hydrogen molecule (H2 ) reacts with o2 molecule of oxygen it gives water. Hydrogen powered cars basically works on this reaction.

Hydrogen combustion cars:

We know the equation that 2H2 + o2 = 2H2o . This is the basic formula we have been thought over and over again in school . In Hydrogen Combustion cars this same reaction takes place but in the presence of nitrogen(N2) molecules . So now Hydrogen , Oxygen and Nitrogen react in the presence of Heat caused by the movement of combustion pistons. This gives us nitrogen oxide. The reaction is as follows.

2H2 + O2 + N2 = 2H2o + No . Where nitrogen oxide is harmful for your health. Plus the efficiency of Hydrogen combustion cars is 20-35% only, which is quite low

Hydrogen fuel cars

Hydrogen fuel cars are very efficient compared to hydrogen combustion cars. Hydrogen fuel cars have an efficiency of 60% as compared to 35% of hydrogen combustion cars. The reaction here is quite easy to understand.Here two molecules of H2 reacts with one molecule of o2 to give water.

Basic reaction : 2H2 + 02 = 2H2O .

Actual reaction; 2H + o = 4H+ + 4e– + o2 = 2H2O.

Here the hydrogen molecule undergoes separation to form 4 Hydrogen ions along with 4 electrons. These hydrogen ions and electrons react with oxygen molecule to give water.

Why hydrogen fuel cell cars can't compete with electric cars

conclusion: Hydrogen fuel cell having a better efficiency over hydrogen combustion cars. Hence is much more preferable over the other . Plus the absence of nitrogen oxide produced in in Hydrogen fuel cars, makes hydrogen fuel cell cars more logical to go for over hydrogen combustion cars.

Pros of Hydrogen cars:

Hydrogen cars doesn’t cause any pollution compared to regular combustion engine cars.

Hydrogen cars can be refilled like a normal fuel car . We won’t have charging problems like electric cars.

Cons of Hydrogen cars :

Hydrogen is costly as compared to fuel.

Hydrogen is highly explosive.

Hydrogen cars have low efficiency.

I personally think hydrogen is very costly at this point to make a conclusions. Plus the people (Taxi driver, Bus drivers etc) who can’t afford to lose time on filling a battery powered car , won’t probably have that much amount of money for an hydrogen refill. An ordinary individual can manage to recharge his/her EV over night or at his/her work space. But Taxi drivers and the other public transport drivers will lose time recharging their EV. This is a big trade off in their earnings.

A Solution to have a better EV network in India

In my previous blog, I had addressed the issue, Why India presently doesn’t have a good EV network. The major reason behind this is a poor charging station network.

India presently doesn’t have a good network of charging station. The current number of charger in India is highly inadequate and can not meet the needs of everyone. These networks are also concentrated in Urban areas , which make is almost impossible for inter-state travel. So how do you seek the peoples attention towards this environment friendly alternative? Considering Delhi, Mumbai and Bangalore being titled as one the most polluted cities globally. Don’t worry i may have a potential solution towards this issue.

My Personal solution toward this issue.

I guess Governments interest plays a important role in this issue. Yes, i appreciate the fact that the government has slashed the GST on EV’s from 12% to 5%. I guess it was a bold move by the government. Also slashing the GST on chargers from 18% to 12% just is a plus point to the governments side. But this is not enough, the government needs to do more. It has to go out of the box for it’s citizens. I suggest the government to make it mandatory for new buildings above 3 floors should have equal number charging points as to the number of flats in building. This will help each family in the building to have at least one charging point. If a building fails to cater this need it won’t be granted a occupation certificate. All restaurants and cafe should have equal number of charger to table ratio, for getting a licence . This will help the customer to charge their vehicle when they enjoy their meal. Hotels, malls and offices should be packed with charging stations. The government should analyse the major roads for inter-state travel and setup charging spots at a smaller interval. Road side chargers should be installed.

The government should also provide subsidiaries to private charging stations. This will help private firms setup chargers in more places. Adding to the amount of government chargers . Government should also push Indian battery manufacturers like Exide to focus on EV battery production. Indian battery producers should get a tie-up agreement with Indian automakers like Tata and Maruthi. So as to boost the economy. This is my personal opinion on the topic, Government can also follow the Norway method.

Norway Method:

Norway last year recorded 53% of it’s total sales in cars to be EV’s . So why does Norway have so many EV’s ?. The major reason behind this is actually Norway’s government it’s self. The government manages to convince it’s population to go electric, by giving the EV owners a massive advantage over the regular car owners. In Norway EV owners are benefited with 2 years of free electricity for their vehicles. EV owners also do not have to pay any toll and tax for their cars. The government also provides subsidiaries to EV manufactures, to make EV’s as well as to setup more charging stations. So how does the government afford fund so much. This is really smart, the government in Norway convince the it’s citizens to go electric, so that it can save up on Fuel and oil. Then sells all this Fuel and oil to other countries. Hence gaining a larger profit. As we all know fuel is way costlier than electricity.

A good explanation to Norway’s EV secret

I honestly feel that our government should learn from Norway.

We can save up a lot of money by going electric. As electricity is way cheaper than Fuel. This will help our economy grow as well. EV is the best remedy for getting away with pollution.
