This entire area is a mess, I spent a year or so trying to get bidirectional charging set up at home in the UK. I even went to several of the vendors mentioned in that post and said "I've got basically a blank cheque and permission to do whatever you want however you want, even use it all as a case study to make this work" and nowhere could/would do it.

The most frustrating thing is it looks like V2G is easier and more accessible than V2H[1]: it's easier to give control of your battery to your energy provider and bypass your house to help the energy companies than it is just to power your own home with your own car battery.

Technically, this is ridiculous. You don't bypass your house when you do V2G.

My tinfoil hat is clearly making me too cynical when I say this, but I think it's this way because of the relationship between energy providers and law makers. These are the same energy providers that use "changes in wholesale pricing" to justify increasing how much they sell me electricity for, whilst reducing the amount they pay me for the solar electricity I sell them.
