Hmnnn, a solid state method for storing lots of hydrogen that is released by temperature changes. What could go wrong?

It will work great,as soon as they invent the tree that produces hydrogen gas.

Notice they said nothing about weight. This sounds like fairly typical hydride technology so far, I think.

These folks envision recharging by swapping out cartridges!? That sounds like a big step backwards to me. Wasn't it an advance to have rechargeable batteries instead of D Cells? And when extrapolating to automotive applications, this gets really dicey, as does a battery swap program.

Vaporware, definitely.

You can't store enough elemental hydrogen at anything approaching sane pressures. So if this thing exists, it's some kind of chemical storage. Most likely a metal-hydride one or a derivative. And they can't be recharged just by pumping new hydrogen.
