An energy storage system (TES) 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. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. The delivered heat which may be used for processes including power generation and cogeneration. In one application, the energy storage system provides higher-temperature heat to a steam cracking furnace system for converting a hydrocarbon feedstock into cracked gas, thereby increasing the efficiency of the temperature control.

A device for use on water, the device including a hull having a substantially planar base and a propulsion system configured to propel the device in any direction across a plane substantially parallel to the base, where the propulsion system is located above the water, in use.

An apparatus includes one or more thermal storage blocks that define a radiation chamber and a fluid flow slot positioned above the radiation chamber to define a fluid pathway in a first direction. The apparatus includes a heater element positioned adjacent to the radiation chamber in a second, different direction, wherein the radiation chamber is open on at least one side to the heater element. The apparatus includes a fluid movement system configured to direct a stream of fluid through the fluid pathway in the first direction.

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.
