Green steam industrial steam generator process and system

A steam generation method comprising:

• providing a steam generation system including a silo configured to receive granular material into the silo at an upper portion of the silo, a heater arranged at or in the upper portion of the silo to heat the granular material received into the silo, a material transfer system arranged to remove granular material exiting from a bottom of the silo, and a heat exchanger disposed in a lower portion of the silo and arranged to contact granular material flowing downward inside the silo;
• delivering granular material to the upper portion of the silo of the steam generation system;
• delivering electricity to operate the heater of the steam generation system;
• and
• flowing a heat transfer fluid through the heat exchanger of the steam generation system.

A steam generation system comprising:

• a silo configured to receive granular material into the silo at an upper portion of the silo;
• a heater arranged to heat the received granular material to generate heated granular material;
• a heat exchanger disposed in a lower portion of the silo and arranged to extract heat from the heated granular material flowing downward in the silo to generate cooled granular material;
• a material transfer system arranged to remove the cooled granular material exiting from a bottom of the silo;
• and
• a storage silo connected to store the cooled granular material removed by the material transfer system and to transfer granular material from the storage silo to the upper portion of the silo.
