STEP project

The project aims to study and model the configuration and process parameters for thermal storage systems charged by Renewable Energy Storage (RES) electricity. The systems are Thermal Energy Storage (TES) based on fluidized bed modules in series, able to deliver green heat on demand at high temperatures (>400 °C).

The development of a suitable thermodynamic model is envisaged to size the system and simulate operation and performance, through energy charging, storage and discharging cycles for selected time windows, according to the user’s request.

The STEP project, completed in September 2025, fits into the context of innovative thermal energy storage technology, able to provide a solution to address the problems related both to Net-Zero and to grid flexibility.
