NREL: Closed-loop pumped hydro ‘smallest emitter’ among energy storage technologies

They have used pumped hydro as an end land use for closed open pit mines, and they are currently designing them for operating mines that will close in the future.

The Genex project will be used to support other green initiatives including a solar array.

But now I have a new pet peeve: when an author defines initialisms that are never used more than once outside of their definition.
