How Can hydrogen and oxygen be separated from water, so hydrogen can be used as a fuel?
It seems logical that the hydrogen for use as fuel in a water-based planet, so ask! After the hydrogen is used, the residue can recombine with oxygen to produce water again?

Mustang….;
Water will dissociate into its components, Hydrogen and Oxygen at about 1000 F. Its very explosive, don’t try this at home.
Electrolysis.
The only problem is that it takes more energy to do the separation than you get from the combining. So basically it’s a waste of time.
O.K., I am not a scientist or chemist, but when you remove the hydrogen to use in one place you cannot recombine back into water. Look up “hydrogen generator” on the internet, there are many types and conditions for gas and diesel engines! Interesting stuff to say the least! Also be aware of something called “metal embrittlement”. Hope this helps!
Hydrogen actually isn’t that logical as a vehicle fuel. It’s simply the simplest fuel. Hydrogen has a low volumetric energy density. Commercial hydrogen is delivered to consumers in heavy steel tanks at about 2175 psi (150 bar, some of you out there keep confusing bars with psi, they’re different guys!!!) and at that pressure hydrogen gas only has 405 WH/l while gasoline has over 9,000 WH/l without heavy compression tanks. Yes developments are under way to make carbon fiber tanks capable of 10,000 psi so that hydrogen could have the 1/4 the volumetric energy density of gasoline instead of 1/20th. But the fact is, hydrogen requires compression tanks and being the second smallest gas molecule (monoatomic helium is smaller), hydrogen slowly diffuses and leaks through anything, even glass.
The concept of using clean sources of energy, storing that energy chemically in a fuel and using that fuel in vehicles is a very tempting concept and when Sandia National Labs researched more efficient ways of producing hydrogen from water, they found one. It’s called the CR5 reactor where counter rotating cobalt oxide discs are heated to 2,400 Celsius at which point they give off their oxygen and then as the discs rotate out of the heat source and cool to 2,000 Celsius, the cobalt oxide would strip away an oxygen atom from water leaving hydrogen. They soon realized that the CR5 would also strip an oxygen atom away from carbon dioxide leaving carbon monoxide and they knew that a mixture of carbon monoxide and hydrogen gases is known as syngas because it will synthesize any length linear hydrocarbon that you would want including gasoline and diesel fuel. Basically, it would be just as easy to use clean energy sources like solar, hydro, geothermal, wind and nuclear, store that energy as synthetic gasoline for distribution and use in existing infrastructure and vehicles. This means that all the advantages of using hydrogen as a vehicle fuel could be attained without replacing a single car or building a new distribution infrastructure if we simply synthesize gasoline instead of producing hydrogen gas. Remember that clean synthetic hydrocarbon fuel when burned efficiently produces only water vapor and CO2, both of which would just be what the synthetic gasoline was made from.
Hydrogen vehicles does make sense to auto manufacturers as it represents a growth market allowing them to continue the inflated growth pattern that they have followed for over a century. If you want the ideal of using clean power for our vehicles in order to benefit the environment, then hydrogen doesn’t make sense but if you want to continue reporting growth to investors and sell more new cars then is strictly needed for transportation then hydrogen vehicles make sense.
Water can be chemically written as H2O. This means it has 2 hydrogen atoms and one oxygen atom.
There are a number of ways to separate the two. All involve a great deal of energy compared to what you have as a result. High heat, electricity, high heat and electricity are all possibilities. The result will give you H2 and also 0
To use hydrogen as a fuel you “burn” it which is a process of oxidation. That is to say you combine it with oxygen. When hydrogen (H2) burns the result is H20 (water.)
Water is a very stable substance. One of the reasons that we don’t have any free hydrogen on Earth is because it wants to combine very readily with oxygen which we have a lot of in our atmosphere.
It is not logical not to speak of economical or even efficient to use a fuel that is difficult to get when there is an easier alternative. If we suddenly decided we wanted to get hydrogen we wouldn’t get it from water but from natural gas (but there would be pollution as a result.) This is far more economical and therefore available.
