China Demonstrated Its Prominence at the Forefront of Innovative Energy Solutions by Creating This Gravity Energy Storage System.
Far beyond the traditional lithium batteries that dominate the market, a revolutionary approach has emerged in China to store energy using massive concrete blocks. Yes, you read that right. This technique, developed by the Swiss company Energy Vault, may seem unconventional, but it operates on principles already known in energy generation.
In traditional methods, water is pumped to high altitudes, storing potential energy. When this energy is needed, the water is released, moving turbines to generate electricity. The new approach employs the same logic, replacing water with concrete blocks, which can offer significant advantages, especially in locations where geography does not favor water reservoirs.
China and Its Vanguard in Renewable Energy
Rudong, near Shanghai, is already benefiting from this innovation. With the collaboration of giants like Atlas Renewable and China Tianying, the deployment of the EVx system, as it is known, has the potential for an impressive capacity of 25 MW and 100 MWh. Associated with a wind farm, this system promises to not only store energy efficiently but also harmonize the country’s energy matrix.

With a phased launch that began in June, there is an expectation of full integration with the local grid by the end of this year (2023). Energy Vault, not content with merely redefining energy storage, aims to be a key player in the Chinese energy transition.
How Does the “Battery” That Stores Energy Through Gravity Work?
The EVx system operates as follows: During times of excess electricity generation from other sources, such as wind or hydroelectric, concrete blocks are lifted using the excess energy that would otherwise be wasted, thus storing potential energy.
When it’s necessary to release this energy, the block is released attached to a rope; this movement triggers a generator, converting the stored potential energy into electricity.
Although it requires considerable space for its implementation, size does not seem to be an obstacle for China. It remains to be seen whether this type of gravity energy battery will find its place in other parts of the globe.
