It appears that liquid air 'storage' could help the situation a little but it's still clear to me that we need long term solutions to this problem, especially if we're going to see the sort of population growth that's being predicted and the likelihood that migration is going to remain an issue.

Turning air into liquid may offer a solution to one of the great challenges in engineering - how to store energy.
The Institution of Mechanical Engineers says liquid air can compete with batteries and hydrogen to store excess energy generated from renewables.
