Summary: Capacitors for Power Grid Storage. ($/kWh/cycle) or ($/kWh/year) are the important metrics (not energy density) Lowest cost achieved when "Storage System Life" = "Application Need". Optimum grid storage will generally not have the highest energy density. Storage that relies on physical processes offers notable advantages.
