A few days ago I read this article about a fast deployable Hydrogenstation! HFuel - ITM Power - Hydrogen | Energy Storage | Clean Fuel Would something resembling be a good idea for rapid deployment for High Power Chargers? In this way you could connect a freightcontainer full of batteries or capacitors, incorporating a HPC (or 2) to a low power-line! This way no waiting for a high-voltage connection to the grid! Also less influence of the fast-charger on the grid! The container could be charged off-peak, and delivering fast-charging at what-ever peak! Maybe some idea where somebody already thought about?
