Well, that's ~100 kWh per car on the road in Ireland, or about the capacity of a full Tesla. The transition to EVs is going to go hand in hand with the transition to renewables, because then you've got a significant amount of demand you can switch on and off at will (or run in reverse, in the case of battery to grid systems).
The future will probably look something like: under normal use, you set your 100kWh car to be able to use half of its battery for grid stabilization, and in return receive charging at perhaps 1/4 the standard price. If you're planning a longer range trip, you turn that off and your full battery is waiting for you.
- njepa 7y agoAre those batteries actually good enough at cycling that this would work though? What is the cost of degradation?
- reitzensteinm 7y agoVehicle to grid isn't required for what I'm describing; as a first step you can just allow the grid to decide when to charge the cars, which will account for ~20% of total electricity consumption. Tesla claims their latest battery packs will be good for 1 million miles; if true, they'll be more than good enough for vehicle to grid use. Even with today's endurance levels though, there will always be some amount of vehicle to grid transfers use that would make sense, since you can use it to shave off expensive peaks in demand. I don't know about Ireland, but in Australia that gets extremely costly: https://www.afr.com/news/policy/climate/wholesale-power-prices-hit-record-in-march-quarter-20190407-p51bnf https://www.afr.com/news/policy/climate/wholesale-power-pric...
