With a total UK energy consumption of 142 Mtoe ....and the rest of the world vieing for the same battery raw material ....I think a bit more than 5x current capacity might be needed.
As someone who lives off-grid I worry at how much effort is going into batteries for high-end 'luxury' items ....a huge focus on miniaturisation to feed the 'mobile phone and Tesla' demographic ....in terms of locally (and ideally household) generation and consumption size is not the biggest issue ....as a self-generator I want a battery made from non-toxic, non-exotic materials...that can get discharged and sit discharged for weeks without damage, then take full charge again without drama and lasts decades ...I don't care if a 100ah battery is the size of an oil drum .....for domestic use size is largely irrelevant ..... obsession with luxury goods driven miniaturisation is robbing this area of research .
