Hydrogen Power on the Cheap–Or at Least, Cheaper: Scientific American

I just came across this:

Hydrogen Power on the Cheap–Or at Least, Cheaper: Scientific American.

I’m underwhelmed.

It’s just a way to get a cheaper electrolysis – device. Not some new orders of magnitude of efficiency. And the inventor dreams of revolutionizing our energy-economics within a decade. Seems there are different positions regarding if it makes sense to build a totally new infrastructure to create, distribute and consume hydrogen or if it’s more clever to store and use the electricity (that’s needed to split water into hydrogen and oxygen) directly.

In terms of personal transportation, what it all comes down to is the question if there will be effective batteries (meaning storing at least, say, 50 kWh – which would be the equivalent of some 5 liters of gas and weighing no more than about 100 kg, maximum recharge time 5 minutes). I hope for the latter. In my opinion, following the hydrogen way is following the wrong track.

The argument is about that simple: Hydrogen is much more difficult to store and distribute than is electricity – given the batteries suit the case.
