Fine but how do you really utilize that energy? Cannot use it to drive turbines....

It's not used to generate electircity.

When it's needed, the energy is extracted again as heat in the same way. Vatajankowski is using this stored heat, in conjunction with excess heat from its own data servers, to feed the local district heating system, which uses piped water to transmit heat around the area. It can then be used to heat buildings, or swimming pools, or in industrial processes, or in any other situation that requires heat.

So could excess heat from nuclear power stations and you would get electricity as a bonus.
