The heat and electricity energy storage need to grow to 46000 TWh [1]. The current value is about 10 TWh.

Heat storage is quite cheap per kWh and has excellent economy of scale.
Just a note that 46,000 is a 2050 target - which covers current demand AND all the growth in electricity and heat demand over the next 25 years.
That's in line with estimates being bandied about in the Finnish dissertations.
