Hi Mike,
The speaker mentions a cost of
0.02 €/kWh for his concrete flywheels at
6:15.
This info can also be found in the slides:
0:35 Solar energy production : 0.02€/kWh
2:36 Solar + chemical batteries : 0.12€/kWh
(so chemical batteries cost 0.10€/kWh)
6:16 Solar + concrete flywheel : 0.04€/kWh
(so concrete flywheels cost 0.02€/kWh)
As for flywheel capacity, check out the company website:
