Title:
GREEN ENERGY THERMAL STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/063933
Kind Code:
A3
Abstract:
A green boiler includes a thermal energy storage vessel containing a captive bed of a thermal mass composition operable to store thermal energy, an array of heaters embedded in the mass, and at least one heat exchanger comprising a tube bundle. The heaters in one embodiment may be electric and coupled to an electric power source to heat the thermal mass. The tube bundle comprises tubes embedded in the thermal mass composition which are configured to convey heat transfer fluid (e.g., water or other) through a tube-side of the tubes. In operation, the heat transfer fluid is heated by absorbing stored thermal energy from the thermal mass composition. The thermal mass composition may be heated by power extracted from the power grid during off-peak demand periods in some embodiments. The vessel may produce heated water or steam for district heating, or steam for power generation or industrial uses.
