Not to mention global annual battery production amounts to less than 1 hour of the USA's national electricity usage.
- ben_w 6y agoYour first point is valid, but I think the second is using the wrong measure — as batteries are rechargeable, surely the measure should be total existent batteries not annual production of batteries? (I would be surprised if this was viable even with my suggested measure, no argument there!)
- manfredo 6y agoLiquid natural gas freightliners are also refillable. I'm not sure what you mean by this. A cargo ship filled to the brim with batteries still has orders of magnitude less energy as a ship filled with the same mass of natural gas.
- ben_w 6y agoGlobal annual battery production has to be first integrated with respect to time and then multiplied by the turn-around time to calculate global annual capacity to ship electricity by way of charged batteries. I absolutely accept that this is a poor solution, and that I am quibbling over a factor of perhaps 500 at most when it’s short by a factor of ~250,000.
