Disclosed techniques include energy management with multiple pressurized storage elements. Energy is obtained from one or more energy sources. Energy requirements are modeled over a first time period and a second time period. A first subset of the energy that was obtained is allocated for storage in a first energy store based on the modeling. A second subset of the energy that was obtained is allocated for storage in a second energy store based on the modeling, where the second energy store comprises a pressurized storage element. Energy is routed to the first energy store from the second energy store based on the modeling. Recovering energy further includes using the energy routed to the first energy store or the second energy store, based on the modeling.
