Your link says "battery storage and pumped hydro will have complimentary roles to play - batteries focusing on the flexibility and speed and ability to provide system services, and pumped hydro on dealing with longer storage requirements, such as extended periods of low wind and solar output." It acknowledges that battery electric storage is short-term only, meant to smooth out daily peaks.
- ViewTrick1002 1y agoAt current costs batteries are best suited for daily cycling. A few years ago batteries were best suited for multiple cycles per day on the ancillary markets. Given the recent auctions in China we are starting to see batteries where a cycle every second or third day is enough. It is essentially optimistic technobabble for the technology losing out about a potential issue coming in 10-15 years as we decarbonize. Please do explain why we should lock in a solution for that today instead of solving it with the technology at hand when we get there.
