Gravity Energy Storage Using Dense Mineral Water Suspension

The patent replaces expensive, hazardous lithium-ion batteries with a safer alternative using abundant materials (water, sand, common minerals). The system uses a porous substrate saturated with electrolyte solution that can be easily replaced if needed, rather than relying on complex battery chemistry. This achieves comparable energy storage with dramatically improved safety by using non-flammable, non-toxic materials.

The invention creates a composite energy storage system combining a porous substrate (such as foam or fibrous material), electrolyte solution, and electrode materials. This composite structure provides both energy storage capability and inherent safety through the physical properties of the materials - the porous structure allows for heat dissipation and the electrolyte solution is non-flammable, eliminating thermal runaway risks while maintaining storage capacity.

The patent incorporates a liquid electrolyte solution-based system that uses hydraulic principles for heat management. The liquid medium naturally circulates and dissipates heat through convection, preventing thermal buildup. The system can be configured with channels or porous structures that facilitate fluid flow, ensuring continuous heat removal and preventing the thermal issues that plague solid-state batteries.

The invention utilizes the liquid phase of the electrolyte solution to manage thermal energy. The liquid electrolyte can undergo phase transitions (such as evaporation at controlled rates or freezing point depression) to regulate temperature. This phase-based thermal management provides passive cooling without additional energy input, preventing short circuits and thermal degradation while maintaining operational safety.

The patent employs abundant, non-toxic materials such as water-based electrolyte solutions, common minerals, and readily available porous substrates. These materials can be easily sourced and replaced without environmental concern. The system eliminates the need for rare earth metals, toxic chemicals, and complex recycling processes associated with conventional batteries, providing a truly environmentally benign energy storage solution with minimal lifecycle environmental impact.

The invention creates an inherently safe, inert energy storage environment using water-based or non-flammable electrolyte solutions that cannot support combustion or release toxic gases. The system operates in a chemically stable environment that prevents harmful reactions, eliminating fire risks and environmental contamination concerns. This inert approach ensures that even in failure modes, no harmful substances are released into the environment.

The patent enables preliminary energy storage by capturing excess renewable energy during periods of high generation (when sun is shining or wind is blowing) and storing it in the porous electrolyte-based system. This stored energy is then available for later use during low-generation periods, effectively decoupling energy generation from energy consumption timing. This preliminary action ensures continuous reliable supply regardless of renewable source variability.

The invention provides continuous energy availability by maintaining a constantly charged porous electrolyte storage medium that can discharge steadily. The liquid electrolyte system allows for continuous ion transport and energy release without the intermittent operation or degradation issues of chemical batteries. This continuity of useful action ensures that renewable energy can be reliably distributed at constant rates, smoothing out generation variability and ensuring uninterrupted power supply.
