Wouldn't it be nice to have a machine that could cheaply manufacture a gallon of gas per hour for your automobile? Envisioning the day when we may all have fuel cell cars, General Electric researchers have built a prototype that makes the equivalent quantity of hydrogen: plug it in, and it splits water molecules to generate one kilogram per hour of hydrogen.
The basic technology, called an electrolyzer, is nothing new: water is mixed with an electrolyte and made to flow past a stack of electrodes. Electricity causes the water molecules to split into hydrogen and oxygen gases. What GE has achieved is a potentially inexpensive, mass-manufacturable version of the technology.
Whereas traditional electrolyzers are made with expensive metals requiring hand assembly, a team at GE Global Research in Niskayuna, NY, came up with a way to make them largely out of a GE plastic called Noryl that is easy to form and resistant to the highly alkaline potassium hydroxide electrolyte. To get more hydrogen out of a smaller electrode, the researchers borrowed a spray-coating process normally used for jet engine parts to coat the electrodes with a proprietary nickel-based catalyst that has a larger surface area.
Their prototype of an easy-to-manufacture apparatus could lead to a commercial version that produces hydrogen via electrolysis for about $3 per kilogram -- a quantity roughly comparable to a gallon of gasoline -- down from today's $8 per kilogram. "We've attacked the capital costs," says Richard Bourgeois, an electrolysis project leader. GE could potentially manufacture the machines within a few years, he says.

The KEY is in the article - GE can make it for $3 a gallon as compard to gasoline. Which means we are about 10 years out from using hydrogen for the masses
Natural gas is even cheaper for home use to heat.
What makes sense is for hydrogen to used as storage.
A prediction.
One of the cold northern states - ND,sd, Main or even a midwest state, will build a series of nuclear plants to produce hydrogen and ship via pipeline, south! Especially canada
Oil we have enough for the next 300 years, the issue is not do we have oil is what type of oil, we are running low on stick a pipe in the ground and out comes oil oil. What we have plenty of is oil in other forms (shale oil, coal, oil, oil in odd ball locations)
But to use this oil, you have to add $$$ to process it.
One of the keys that I saw was when oil goes to 70$ a barrel many other technologies now become cost effective.
which is why you saw the price of oil come way down recently.
Friend of mine started to biodiesel, but it is $3.25 a gallon not bad when diesel was 3.15 but terrible when it is 2.75. Same thing with ethanol.
also do research on hydrides - they can allow the storage of hydrogen -
We are getting there!
