In 1890s, internal combustion engine was a fresh technology and it was a great opportunity to replace inefficient horses which have limited top speed of seventy km/h. There were some electric engine cars and plans to run diesel engine with peanut oil but they were all died by petrol. End of 19th century was the rise of the petrol, people find out that petrol is something very vulnerable and can be used in cars. It can be considered as petrol is invented a bit earlier than petrol engine! And this made it very easy to fill the cars’ tank. Engineers did not invent an engine which is using something that does not exist!
However the case is totally opposite now! We are trying to find ways to use electric cars and hydrogen cars. But both of them cannot be filled very easily. Honda’s fuel cell car works on hydrogen and it does not emit any emissions at all :) That’s a great news but producing hydrogen is an expensive and complicate process. It will take decades to have hydrogen filling stations like petrol stations. So the car is ready but its fuel is not ready!
With electric cars, situation is a bit complicated. We can charge our e-car by plugging into our wall at home but it takes very long time to charge and electricity is not something cheap and you still emit emissions while charging it. One other fact; if we all drive electric cars and charge them at night, we could end up burning the whole electricity network which is not designed to charge whole countries’ cars! So, there should be a huge investment to upgrade electricity network for charging our cars.
In the two alternative cases, invented technology is moving faster than the fuelling technology. I cannot say the exact for hydrogen cars but I could see one thing clear, we will drive petrol engine for quite some time.
