“## The world's first fully passive grid-scale energy storage #### The world's first fully passive grid-scale energy storage ##### Zero moving parts. 20 years of no scheduled maintenance. 96% round-trip efficiency.  ###### Our Product #### Fully-passive means reliable & efficient. ##### Incumbent systems on the market are car batteries in a grid enclosure. The bolt-ons that keep them alive - fans, chillers, fluid loops - are where most failures happen and where most of the operating cost goes.
