Using compressed hydrogen, and injecting water will produce more energy output than hydrogen alone - Is this the way to go?

Answer 1

i guess if ucan afford um

Answer 2

Hydrogen..

It's not the best way...

This video is likely a fraud....i've seen it, I saw this news when it broke, and the company has yet to allow verification.  There are hundreds like it all over youtube, people claiming over unity and such.  Many are years old and still floating around while this one is relatively new.

I've crunched the numbers hundreds of times, and even with the most optimistic values, a hydrogen economy is not sustainable or practical.

Here's the conclusion i've derived.

It takes electricity to produce hydrogen.  The amount of electricity used to split water, is directly proportionate to the potential energy you could possibly gain.  Electricity is already the most pure form of energy, so any conversion from that is a loss period...especially when we're talking about the combustion of hydrogen.  The injection of whater to "boost" a combustion reaction sounds pretty fishy to me since water is not combustable, it sounds like an inefficient steam engine to me.

The only sensible way to go is pure electric.  There is no point in adding a second hop in the energy consumption chain, or using combustion engines for transporation.  Electric motors are up to 95% efficient in the conversion of electricity to work.

Also there's the problem of portability.... hydrogen is hard to transport...it has to be cooled and compressed which takes additional energy(electricity).  Electricity, is the easiest form of energy to transport...you just send it over a wire using existing infrastructure.  Battery technology has advanced rapidly, and batteries are also up to 99% efficient in storing and discharging electricity.

Safety could also be an issue as everyone would be driving around with a 1kiloton hydrogen bomb under their carriage.

So... the answer to gaining energy independance, going totally green..., is in this question....how do we generate vast amounts of electricity without using coal ?

Answer 3

From the research I've done, the info is available on the net to build and do your own testing for as little as $65. I'm going to continue researching and at some point build and test my own unit to see for myself. I suggest you do the same. As far as the other answers you've received so far they are all way off. Obviously they don't even understand the question. By water injection I understand what you're talking about is using your cars electricity to turn water into HHO that can be sucked into your engine and burned a long with a smaller amount of gasoline to save fuel costs. They don't get it so don't listen to them. Check into and build your own or you'll never know. It makes sense. Seems like it would work at least a little. I'm trying to decide how much fuel can be saved to determine if its worth it. Again, I'll have to test a unit myself before I make up my mind. Don't trust anyone who has never tested it themselves. Good luck.  

Answer 4

Wow, It sounds like an interesting idea.  It seems that it still needs hydrogen also, which may be the biggest hurdle to getting the car mass produced.  Also, it would be curious to see how much water would become if it also had to run our cars as well.  

I like the innovation, but I am not sure how practical this is.  I still say that large amounts of clean energy is still the way to go and to have plug in electrics.

Answer 5

90% of all Hydrogen is made from natural gas or oil as that is the cheapest way to make it.  The price of H2 is 3 times the price of natural.  So why pay 3 times the price?

Answer 6

To extract hydrogen from water large amounts of energy are required, I believe the energy cost is 3 times greater than running a car on petrol so it doesnt really stack up. However, if they could do this with clean power generation it would be a cleaner alternative, but as this is costly it probably wont happen and coal power will be the power source.

In the USA its being pushed as the next "green fuel" as water can effectively be turned into money and hence it will be very profitable for a select few and it will make end users feel all warm and fuzzy.
