A safe energy supply unit (1) and system, for supplying an electrical device (8) in an explosion-proof area, transmits power from an energy source (9), including a plurality of galvanically isolated individual sources, with a multiple line connection (2) with a plurality of galvanically isolated and individually shielded conductor pairs (31, 32, 33, 34). A collector device (4), in an explosion-proof jacket (5) at an end of the multiple line (3), has uncoupling devices (45) for the galvanically isolated conductor pairs and a combiner circuit (47, 49) that combines the transmitted electric power from each line into a global power. The global power is outputted at an output (48) of the collector device to the electrical device. The conductor pairs allow for an increased global power, which is scalable, safely transmittable, with standard, conductor pairs. The electrical device is intrinsically safely supplied with high power with minimal effort.

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.
