Modular Particle Thermal Energy Storage Systems

A system comprising:

• an electric heater;
• a first storage silo;
• a media/air heat exchanger;
• a second storage silo;
• and
• a media transport system;
• wherein:
• the electric heater and the media/air heat exchanger are positioned between the first storage silo and the second silo;
• the media transport system is configured to move a media between the electric heater, the first storage silo, the media/air heat exchanger, and the second storage silo, and
• the media/air heat exchanger is connected to an energy user.

A method comprising:

• heating a media using an electric heater resulting in a heated media;
• first storing the heated media in a first storage silo;
• cooling the heated media using a heat exchanger resulting in a cooled media;
• and
• second storing the cooled media in a second storage silo;
• wherein:
• the electric heater is positioned above the first storage silo,
• the first storage silo is positioned above the media/air heat exchanger, and
• the second storage silo is positioned adjacent to the media/air heat exchanger.
