NGK pulls plug on world’s second-most-deployed grid storage battery technology after BASF exit

Key Takeaway

The discontinuation of a major grid storage battery technology by a key OEM signals market consolidation and impacts future battery chemistry choices for developers and large power consumers.

AI Summary

  • NGK Insulators has discontinued its sodium-sulfur (NAS) battery product line, a technology previously ranked as the world's second-most-deployed grid storage battery.
  • The decision to cease production was reportedly influenced by the exit of NGK's partner, BASF.
  • This move reduces the available options for grid-scale energy storage technologies, potentially shifting developers and large power consumers towards alternative battery chemistries for future projects.
