We'll likely lick this problem within the next 25 years! Whether it's an electrochemical battery or a fuel cell remains to be seen.

An EFOY hydrogen fuel cell you can buy today for your motorhome. Only $7000 for a 2.5KWhr unit. Gasp!
I know we are getting away from the topic a bit but here is a video on the Fuel Cell concept way back also. in this same series you can find a vid on the corvair Electro-Vair II

I am surprised how slow all electric cars are catching on. I have a hard time finding charging stations for my Fiat so I don't use it unless I can return home on the 90 mile range. We put 10,000 miles on it this year but most consumers don't have a backup long range car available. I have several cars and can even visit a customer with a M923. I think green Diesel will pass the all electrics before the hydrogen cell advances and takes off. For my 77 GMC project I am kinda set on using a Yamaha EF4500iSE.This Generator is called an Inverter. I always understood an inverter to be the device that changed 12 volt battery energy to AC 120 volt electric but here it is a device that replaces the batteries with a gas engine and an alternator. Here is how HONDA describe their inverter/generator

[[Honda 's inverter technology takes the raw power produced by the generator and uses a special microprocessor to condition it through a multi-step process.
First, the generator's alternator produces high voltage multiphase AC power. The AC power is then converted to DC. Finally the DC power is converted back to AC by the inverter. The inverter also smooths and cleans the power to make it high quality. A special microprocessor controls the entire process, as well as the speed of the engine.]]

I wonder if the process of using a Inverter/Generator and an Inverter Battery charger to charge a storage bank of DC Batteries can be improved by the engineers at Honda? I believe there is some caloric loss some place that can be recovered? As it is now, my Yamaha will be Making AC then DC then AC then my Xantrex inverter/charger will be taking the AC to make DC to charge the batteries. AC-DC-AC:AC-DC. the last conversion of AC to DC is in the Inverter Charger when they detect incoming AC from the Yamaha Genset. I think Honda has a small 12 volt charger on their i1000.
I do think this discussion should be part of the new power storage technologies because any power you store originated at the genset and one of the issues has been the lost power produced and not captured when the diesel genset runs with a lite load.
