Do you mean Nafion?  If so, it's a polystyrene-based polymer made by DuPont.  It's being used currently in fuel cell research.

It's a monomer derive from petroleum , exactly how I am not sure  since I only do plastics.\n\nThe monomer is receive as is for polymerising to make   ,  pe , polyethylene.  Which makes the our plastic bags and some hoses (aquarium hoses).\n\nOn the re-cycle logo you can see "pe" , because today we have to declare. \n\nWhen the primodial bog sinks and plants turn to gas , petroluem and coal , ethylene is somewhere in there.\n\n** therefore the energy is solar at source , origin.

Some pros to this energy source are: 1) Vast new source of energy 2) Fuels (mostly hydrogen) are plentiful 3) Inherently safe since a malfunction results in a rapid shutdown 4) No atmospheric pollution leading to acid rain or "greenhouse" effect 5) Radioactivity of the reactor structure, caused by neutrons, decays rapidly and can be minimized by careful selection of low-activation materials. There is basically only one con to these energy sources though. Scientists have not figured out a way to make it efficiently. At this point they have sustained a reaction at the break-even point, which essentially means they used as much energy as they created to make the reaction take place.

Hydrofluoric acid (HF) is what you need. The hydroxyl group will attach to the hydrogen (making water) , and the fluoride will move on to the rest of the molecule.

It is a polymer made up of two different monomeres. If it is used in batteries it will likely allow ion conduction, i.e. the migration of ions through the polymer. No idea whether an additional solvent is required, though.

Apparently groups in Sweden, Australia, and the UK are working on this. There are probably others as well. They are making progress. It does appear that this might allow the industrial scale separation of water into hydrogen and oxygen, and the reduction of atmospheric CO2. \n\n\nRecently, Jim Barber and So Iwata of Imperial College in London identified the actual crucial molecules that are used to split water by plants. This might lead to huge advances eventually. It is quite exciting.

Balance the equation, you have more hydrogen on one side than the other.

thermal depolymerization is what you're looking for.  Water, heat, and pressure will do for the first step.  Reforming the produced oil, usually light fuel or #2 diesel (C14/C14+), into "petrol" (C7-C12 ?) is best done with zeolites.

Its best to think of hydrogen as a 'battery' rather than a power source.  Because we don't have incredibly abundant supplies of free hydrogen on earth, it is not practical for use as an initial energy source.  You are also right in your assertion that it will always take at least as much energy to create hydrogen as we can get by using it, in accordance with the first law of thermodynamics.  \n\nHydrogen is, however, viable as an environmentally friendly fuel to operate vehicles.  This is because the conversion of hydrogen into energy is essentially pollution free and is of high efficiency.  Thus if we use an environmentally friendly power source, such as solar power, to produce the hydrogen, we can run vehicles in an essentially pollution free manner.  As a result, a switch to hydrogen fuel cell vehicles would allow reductions in the overall emissions of our national power production to be reflected in reduced total energy cycle emissions of our vehicles.

pressure adds energy increases the activation energy of the bonding reactions such that a different geometry is achieved

Hydrogen is a combustible gas and can be used to generate energy.  Hydrogen powered cars are presently being researched and are called 'fuel cell cars'.\n\nYou can get hydrogen from brine (salt water) by the process of electrolysis.

I think vulcanisation helps in doing that. We heat rubber with Sulphur to make it stronger.

Just how much Hydrogen do you want to produce?\nI could tell you several ways to make small amounts for next to no cost, but if you want to step up production, it will involve increase the price too.\n\nElectrolysis of water is probably the cheapest method, especially when the energy your using is cheap/free too.  The cheaper the energy, the cheaper the over all price.  The energy from a battery is much more expensive than the energy "out of the wall" which is much more expensive than energy from the sun (free).\n\nYou could also produce Hydrogen by reacting a more active metal in an acid.  Metals like Iron, Zinc, Magnesium, (you could use the Alkili metals, but I woulnt advise it), ...\nCopper (in a penny) wouldnt work since it is less active than Hydrogen, but the zinc inside the penny would. [we ignore the cost of the penny you have to destroy]

yes its possible. yes a few people have already done it.\n\nit takes 24 volts DC (2 car batteries) passed across a pair of platinum electrodes within a vessel of deionized water. you must exclude all air from the vessel prior to starting the process. also there must be a divider within the vessel so that when the hydrogen and oxygen separate (one gas type bubbles up from each electrode)\n\nnow you can compress the hydrogen and use it as fuel. (it takes 5 psi to run in a standard carberated engine)\n\nOR\n\nyou can store hydrogen in beryllium as it absorbs H2 readily at high pressures and releases H2 at low pressures for use with a fuel cell and because it is trapped in a block of metal no O2 can get to it to cause it to burn in storage.\n\nnow here is the problem with using this as a wide spread fuel.\nit takes more energy to create it than it puts out. unless you want to build a big solar array to convert a little water, it just doesn't fly.\n\nnow some people are working with collecting H2 emissions from some varieties of algae. now that looks promising.
