"World's largest" 30MW flywheel energy storage project connects to grid in China
- toomuchtodo 2y agoI am not a mechanical storage person. Can someone who is or adjacent provide context if this will ever be cost competitive with lithium or sodium battery storage (which can also provide grid support)?
- s1artibartfast 2y agoIt doesn't have to be cost competitive because it offers additional function. Mechanical storage (and generation) provide frequency regulation as well.
- toomuchtodo 2y agoBatteries do frequency regulation, and respond within ~200ms of an anomaly, faster than any mechanical inertia or spinning generation can. If they’re at cost parity or cheaper than the flywheel, why flywheel? https://www.ercot.com/files/docs/2024/01/12/Tesla%20BESS%20Grid%20Forming%20and%20Augmentation_ERCOT.pdf https://www.ercot.com/files/docs/2024/01/12/Tesla%20BESS%20G...
