This invention discloses a method, device, and system for the direct electrolysis of seawater without desalination for hydrogen production. By immersing the direct electrolysis device for hydrogen production from seawater without desalination directly into seawater, driven by the pressure difference at the interface between seawater and the self-driven electrolyte, seawater continuously enters the device through the solution mass transfer layer. The self-driven electrolyte induces the water to enter the electrolyte solution, while the hydrophobic action of the solution mass transfer layer effectively blocks non-water impurities in the solution. During electrolysis, the water in the self-driven electrolyte is consumed to produce hydrogen and oxygen, inducing the regeneration of the electrolyte, maintaining the pressure difference at the interface, and achieving a self-circulating excitation drive without additional energy consumption.

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.
