Content Data

This page contains data entry 79869 from the Axioma AXP content repository. The structured data below represents the complete record for this entry.

Your calculation is off somewhere (what is a "cube of water"?). Raw energy density (without taking losses into account; typically pumped storage has about 70% to 85% efficiency) of pumped storage is a meagre 272Wh per cubic meter of water and 100m of height difference. With only 50m height you'd need to pump up about 1000m³ of water (about half of an olympic swimming pool) to get to your 130kWh figure.
