A system includes an air compression train, a compressed air storage, an air expansion train, a heat management subsystem, and a power transmission subsystem. The heat management subsystem is configured to receive a heated heat transfer fluid flow and to provide a low-temperature heat transfer fluid flow to the air compression train from a low-temperature heat transfer fluid storage vessel. The heat management subsystem is coupled to the air expansion train and is configured to receive a cooled heat transfer fluid flow and to provide a high-temperature heat transfer fluid flow to the air expansion train from a high-temperature heat transfer fluid storage vessel. The heat management system is configured such that a first heat source is coupled to the high-temperature heat transfer fluid storage vessel.
