People talk about hooking cars up to the grid, and charging them during times of excess power, and then selling that power back during peak.
Yet, that shorten battery lifespan a lot (imagine a car charged weekly to get around town, now discharged/charged daily... battery life is now 1/7th).
There is also loss during charging, and discharge, loss in power lines too.
Meanwhile, you could create h2 right at the power plant during time of excess. Like at a dam.
Then just send all that stored energy via pipelines, just a with natural gas.
- epistasis 5y agoCycling batteries small percentages around mid level charges does almost nothing to battery life. Already, it's expected that we will soon have car batteries that outlast the rest of the car, with million miles lifetimes. Plus, there's a specific cost to the battery life, that can be calculated, and evaluated against the gains from arbitraging electricity prices. If batteries are economical on the grid, and they are increasingly replacing natural gas peakers for cost reasons, then car batteries will be a huge resource that is an economic win for car owners and for electricity rate payers.
