Description

Technical Field

[0001] The utility model relates to a gravity block structure for gravity energy storage, belonging to the technical field of gravity energy storage equipment. Background Art

[0002] In recent years, my country has clearly stated its commitment to significantly increase the scale of wind and photovoltaic power generation, building a new power system dominated by renewable energy. This commitment will also enhance the flexibility of the grid system and improve its ability to absorb renewable energy. However, the output of wind and photovoltaic power is limited by natural resource endowments, and the mismatch between power generation and consumption is a key issue that needs to be addressed for wind and photovoltaic power generation. Energy storage technology involves storing excess electricity in storage devices and releasing it when demand is high. The combination of resources, power generation requirements, and energy storage systems are all crucial to ensuring the reliability, flexibility, and affordability of power supply.

[0003] Gravity energy storage, similar in principle to pumped hydroelectric storage, is currently progressing from theoretical research and small-scale trials to large-scale commercial projects. It uses electricity to lift heavy objects to a height, increasing their gravitational potential energy for energy storage. As the objects fall, this gravitational potential energy is converted into kinetic energy, and then into electricity. Gravity energy storage involves no chemical reactions in its processes, including transporting heavy objects, storing potential energy, and generating mechanical energy. It operates safely and reliably. Gravity energy storage is clean, low-carbon, and has minimal impact on the environment. The storage, transport, and power generation processes require no special conditions or requirements, making gravity energy storage power stations virtually unrestricted by external factors like site selection and weather. Their application is highly flexible, allowing for flexible deployment on both the grid and power supply sides to meet power system needs. Gravity energy storage boasts an efficiency exceeding 80% and a cost half that of lithium batteries. Compared to other energy storage methods, gravity energy storage offers significant advantages, including environmental friendliness, flexible deployment, high safety, long lifespan, and no self-discharge. It holds significant research and development value and holds broad application prospects.
