An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.

The invention provides a water tank heating method and unit, an electronic device and a solid oxide fuel cell (SOFC) system. Before the SOFC system is started, ice in a water tank has been heated up, so after the SOFC system is started, the heating time of the heated ice, i.e., the thawing time of the water tank, will be shortened. Further, in the ice heating process, a pre-set needed SOFC thawing time determined according to current stack outlet temperature is used as a heating control parameter. As the stack outlet temperature is a key factor influencing the starting time of the SOFC system, the heating control will be more accurate if the pre-set needed SOFC thawing time corresponding to the stack outlet temperature is used as a heating control parameter.
