Tesla plans to build a lithium-ion battery array capable of storing 129 megawatt-hours of energy. Wait... 129 mega-whats? What is a megawatt hour, and just what could you do with all that energy?

This Could Definitely Be Big
Some of the important questions remaining, though, will be not only cost, and durability, but the watt hours per kilo of weight. In that vein, will such batteries be better than the combination of, say liquid hydrogen stored (with its cryogenic containment), and the added weight of some form of generator? It will be interesting to see; especially when you also factor in total lifetime costs and all (do we know yet, in point of fact, how difficult recycling these batteries will be?).
