Elsewhere, Israel’s Nostromo Energy became the latest vendor to bring a data center “ice battery” to the market. Ice batteries work by cooling ice stored in cells at times where demand for power is low. The batteries use the cold temperature of the ice to chill the cooling liquid needed in HVAC systems, eliminating the need for mechanical chillers, which are big consumers of electricity. Nostromo believes it can make up to 40 percent of data center power consumption flexible, which could be a big boon for operators looking to trim costs.
This is actually a good example of dispatchable demand response - It's like an ipdated version of the practice of making nice at night.
