Hydrogen comes from water. Oil comes from pits deep in the earth. To turn an engine: We make controlled explosions inside a steel chamber to turn a crank using refined oil. The theory of operation does not change for hydrogen powered cars, the process of extracting it does. Hydrogen: A truck pulls up to a beach - drop a hose - tank is full so wrap up the hose and drive off. For oil - first you need gigantic oil pumps, then you drill a massive damned hole in the ground. At this point hydrogen is easier. The absolutely insanely stupid statement of "they explode", yeah you moron, so did the Gremlin when they got rear ended, you don't blame the fuel you blame the engineer. Complete idiots speaking their mind think they know, but in reality hydrogen and oxygen could replace oil and natural gas over night and there would be no change so long as the systems were engineered to handle the change in gases. Mostly it would be flow reducers because hydrogen and oxygen burn hotter and faster than oil and natural gas. But any explosions outside of the engine itself, are engineering failures, not of the fuel type which is one of the dumbest uneducated statements I have ever heard about a fuel type - " it blows up so I don't like it" you rancid hotdog, what do you think gas does? A gallon of gas can send a 1 ton car 30miles, if you ignite it directly it can send every part of your body 30miles in every direction. IT'S WHAT FUEL DOES!!! WHAT MATTERS IS HOW WE ACQUIRE IT! THE TECH IS BUILT AROUND THE FUEL! Weak damn humans.
Gonna clarify a few things...
This is like saying flour comes from cake. You've got it backwards.
Hydrogen opens up the possibility of using a fuel cell, skipping the noisy and inefficient combustion in favor of directly creating electricity and driving an electric motor.
Not even close. To get hydrogen from water, you need a shit-ton of electricity and a lot of infrastructure, or you need to free it up with a chemical reaction (Aluminum and hydrochloric acid if I remember correctly). Right now the chemical way is lower cost and more available.
It's better to use that electricity to move the car around, rather than split water with it and using the resulting hydrogen to move cars.
I get your point but hydrogen isn't just sea water, you've got an awful lot more energy to put in after the "tank is full so wrap up the hose and drive off" stage to separate the hydrogen from oxygen to get the fuel. The difficult bit comes after "get water".
And It generally requires a lot of electricity. So, batteries cut out the middleman.
