I always wondered if flywheels[0] would be a good alternative to batteries to store energy. Flywheels can absorb peak current, help stabilize grid frequency[1] and can
have high efficiency.
But I haven't seen much on the topic, and a lot in chemical batteries.
What are the prices and downsides of flywheels? Does anyone have an up date comparison of commercial solutions with TeslaWall and similar?
