Hydrogen fuel cell car! HAHA!

Ok, so to produce a liter of gasoline, you use about 7 MJ of energy. A liter of gasoline contains 34.8 MJ of energy.

To produce a volume of hydrogen with 34.8 MJ of stored energy, you need in excess of 34.8 MJ of energy.

How are these two even comparable?

 

All you have done is stated properties. You are the one that wanted to differ between source and storage. You have failed to define either. If you want to say oil sits in a reservoir fine... but that has nothing to do with classifying what is a storage and what is source... because they are just terms of conversation with no real definition when it comes to chemistry and physics. You are playing semantics.

I will take your energy contents... and those contents were based on oxidation results and joules and are an acceptable way to express them. What that tells you is that there is that much chemical energy in the bonds... that when the weakly attracted hydrogen breaks from the carbon and the carbon combines with oxygen.... then a lot of energy is released. Guess what... what do you think happens to that hydrogen now floating around free... it combines with an O2 as well and releases heat... just not as much as carbon.

So great... now we know another valuable bit of data. But what does that have to do with your original statement? Energy content is exactly why hydrogen is a poor energy source. Hydrocarbons are much easier to transport and distribute. Much easier to produce, and are much more energy rich. Makes hydrocarbons an excellent SOURCE of energy. Makes Hydrogen a very poor SOURCE of energy for use in transportation.

 

You can't produce unlimited quantities of hydrocarbons via a synthetic process. It takes far too long, under a hugely complex set of circumstances, to create them.

You can easily do so with hydrogen, as the moment it's used (and thus converted into water), you can add energy again and get more hydrogen.

 

Im gonna weigh in here.... I think everyone has made valid and good points but I belive that untile everyone is willing to stop and say we have to find another alternitve there really wont be a solution. Our society just wants it now thats GAS vs productive and cheep HYDROGEN (for right now) it also sounds more like an additive vs an alternitve fuel IMO.

;D thats my 2 cents

 

So is that your definition of source and storage.... how long it takes to produce synthetically or naturally

 

That's what is funny... every now and then somebody thinks they have stumbled upon a free lunch and found something new. Hydrogen fuel cells sent Apollo to the Moon. It's nothing new. Hydrogen is nothing new. Combustion is nothing new. Hell a battery powered car was first made in the 1800s!

Yet with all the Teslas out there, all the rocket scientists, all the multi million dollars companies trying to become multi billion dollar companies... somebody comes along and thinks they have found the one secret all those guys missed right in front of their face.

Don't get me wrong...significant improvements to designs... breakthroughs of thought have occurred in a garage... Apple comes to mind... but Jobs did invent the simi conductor... that was a lot of geeks in a big lab with millions of dollars.

The combustion engine has been beat to death. there is no free lunch.

 

Hydrogen is not something we really create, ever look up at the sky and see that big bright sun up there? well it's primary fuel source is ....hydrogen, which then breaks down into helium and so on. But to use it as fuel in our enviroment, it takes considerable efffort.

BTW, The real concern here is not just about fuel, it's about enviroment- carbon based fuels are slowy killing our planet.

As per wiki; Fuel - Wikipedia, the free encyclopedia

 

Ok let's deal with the facts here:

Again as per wiki: Hydrogen fuel - Wikipedia, the free encyclopedia

 

With the above information as our fact base. And as I stated way back in the start of this debate, to really use hydrogen in a manner that J.Q Public can use- it's a no go. Can it be done- sure, is it safe? NO. Is it economically viable? NO.

There fore, until someone creates a way to change the above two - you will never see this used by the mainstream public.

Now if were going to talk of a fuel source that is truely free- PLASMA, the trick is containment. ;D

 

PLASMA like what we have in our blood? lol jk
