Study: EVs with V2H cut household electricity costs and need for home batteries

I'm looking at a new car later this year. The limited options for V2H are disappointing.

As far as I know, in Switzerland they are (still?) blocked by law, might be some market protection or something...

The success of V2H partially depends on it being a technology that’s not just for nerds. It has to be something where the user just plugs in to their house and doesn’t have to think about it. Their energy use is optimized and their vehicle is charged up for the next day.

The other part of this is that all these things sound great, but single family homes with cars as the primary method of transport is a losing strategy for global sustainability. The best way to reduce global oil consumption is to reduce the number of trips people choose to take with cars.

Electric cars, V2H, that stuff is all something of a band-aid compared to building infrastructure that makes it safe and convenient for me to cycle to work or take the bus.

Even in the United States where single family homes are probably more prominent than anywhere else, something like 40% of people don’t live in a single family home.

This is the real ultimate solution to energy security and climate change. However there are many entrenched interests behind car culture. Auto manufacturers. Auto parts suppliers. Car dealers. The banks that sell car loans. Car insurance companies. Oil companies. The majority of governments and voters that are okay with spending on highways, roads, parking. But ask them to upgrade public transit into something useful instead of an awful quality social welfare service and the anti-tax forces come out in force.

But that would accelerate the vehicle's depreciation, which is costly. I suspect it would make more financial sense to have a home battery, they should have compared the prices of home batteries vs car batteries. And for the national grid effects, just charging your vehicle when electricity prices are the lowest would have mostly the same effect but would be a lot simpler.

If there is a net benefit for both the vehicle owner and the utility, the utility should pay the owner. A school district bought battery electric school buses with a subsidy from the utility on the purchase price.

V2G is what we should focus on. Tens (eventually hundreds) of millions of EVs soaking up free power that is being curtailed during the day, supplying power back to the grid later in the evening at peak prices, replacing peaker plants.
