The Hungarian government has launched a residential energy storage program with a budget of HUF 100 billion. Under the initiative, households can install 10 kW battery energy storage systems, with a non-refundable subsidy of HUF 2.5 million to support the purchase.
I think it is inefficient for each home in a neighborhood to have their own battery. Wouldn’t it make more sense to have a big battery for 20 homes or so?
It feels like individual action when collective action is needed.
It really doesn’t matter. Those batteries are small. Smaller than a fridge. Like this one box in your cellar with all that crap in it. So they do not take much space and it’s easier to put them into individual homes (just one party involved) than organizing to put them into neighborhoods (many people involved, which ensures that nothing productive will be done)
But you will need more unused capacity to avoid wasting energy with lots of small batteries than with fewer larger ones. It does matter.
