Here is another source for clean electricity to produce hydrogen for fuel cell use.

And you won't see much action so long as the petroleum and coal giants are dictating our energy policy.
However, I do suspect that they are seeing the inevitable and are attempting to lay claim to the right to control all new and unexploited forms of energy production. We would be fools to allow them to secure that domination.

part of the reason it hasn't moved forward is that geochemistry gets real complicated...
these rocks can have any of number highly dangerous chemical compounds or just plain pain in the butt chemicals that corrode the pipes or clog'em up.
you have mercury, lead, and arsenic compounds for starters... in some areas of India? most of their drinking wells have some levels of naturally occurring arsenic that we would not accept here
in the mid 90's i heard about a geothermal well that was sunk (i think in Australia) and got clogged with gold... can't find a link now, so it may have been a rumor...
you could easily be pumping water wit h a PH equivalent battery acid
add to that the slippage mentioned in this article? you can't predict your costs or even if it'll work...

True, but whatever their bad points, they can't even approximate those environmental evils derived via nuclear energy production and they would be hard pressed to be as as harmful as unchecked use of fossil fuels..

And we didn't understand a lot about corrosion of iron pipes until recent decades, particularly that cause by di-electric states and anomalies. Various sorts of plastic pipe cure much of that as well as providing elasticity and plasticity that helps resist damage via soil movement and swelling.
The examples of drilling deep into the earth to gather temperatures of steam in the hundreds of degrees is only one extreme of means to utilize geothermal energy. It presents hurdles and difficulties, but they caan be studied and many overcome. (Iceland has decades of experience already documented and has plans to completely divorce itself from fossil energy production. Norway isn't far behind.)
The easiest and cheapest way to utilize geothermal energy already well known and mastered. What it amounts to is to simply bury an array of plastic piping 7 to 10 feet below or nearby a building and pump some fluid through that array then through a strategically arranged array throughout the house or building. Temperatures 7 to 10 feet below the surface remain nearly constant year around and quite close to what we achieve via or common methods of heating and cooling.

But it will work well in that setting of 55 to 65 degrees F and it is cheap.
Once you get the house close to that range, it only takes a tiny bit of other energy to make it comfortable
