A version similar to NanoFlowCell concept with only one liquid would be possible

Okay, a new technology I'm not familiar with, that's fair.
If I had more time right now I'd really dig in, but here's what I'm seeing so far:
1) Their smallest systems seem to be container-sized...fine for stationary installations, not going to work for vehicles.
2) The storage of hydrogen into the medium requires 30 bar of pressure, which is over 450 psi.
3) Storage also is exothermic, so would require lots of cooling. Even the smallest size (10-foot container footprint) requires 400 VAC power.
4) Hydrogen storage is only at a 9kg per hour rate, in the footprint of a 10-foot container. This is way, way below recharging rates for any battery.
5) Release is endothermic, so requires a lot of heat energy to liberate the hydrogen -- at 300 degrees C!
6) The 20-foot container release system liberates 0.9kg of hydrogen per hour, requiring 10kW of heat to do so, provided by 400 or 480V three-phase. That output seems inadequate even for a small vehicle. Spec says it can't be throttled down below 50%, either.
Okay, it's an interesting technology, but the size, weight, power requirements and uptake/delivery rates make it completely unsuitable for any sort of vehicle. Further development is always possible, but any idiot can make promises. Actual engineering is far harder.
