The article is about LDES Long-Duration Energy Storage.

(I remember learning of Google's early Bloom Box investments many years ago; instead of diesel generator reserves which expire.)

Energy Dome has a CO2 -based LDES which Google has invested in.

Energy Dome's requires compressing CO2 to supercriticality.

> [...] pumped storage hydropower still accounts for more than 90% of utility scale storage in the US, long duration or otherwise.
