Many things are technically possible. Fewer things are economically practical. Does Europe have the capacity to manufacture batteries that are big enough? How much will that cost and how many years will it take? A few local small-scale demonstration projects don't tell us much about the difficulties of scaling up by orders of magnitude. Have you actually done the math on this or are you just repeating platitudes?

The UK is forging ahead with large scale battery storage projects. I have not done the math, but I assume there is a sound economic case in order for these projects to receive this level of investment.

Edit: Here's some more data on revenue for battery storage in the UK [3]
