Researchers have already tested a 100-kilowatt-hour stone installation.
A team of engineers from Sandia National Laboratories and CSolPower LLC of New Mexico are working on a project aimed at developing an affordable energy storage method using electrically charged rocks to efficiently store electricity. About it reports Interesting Engineering portal.
The system stores thermal energy by heating or cooling stones with air to produce clean electricity, supporting the clean energy transition. The technology has potential for use in a variety of applications, including providing electricity during periods of high demand or when renewable sources are not available.

According to engineers, the setup involves rocks placed in a container that can be heated or cooled using air to store thermal energy.
“We learned that gravel from landscaping companies can be successfully used in the system without requiring extensive rinsing or preparation,” the scientists said.
Experts have already tested a compact 100-kilowatt-hour test rig to evaluate how well rock formation performs at the National Solar Energy Test Site. Photovoltaic panels are currently being installed and modifications have been made to demonstrate the system’s ability to charge using an intermittent power source.
During the testing phase, the bed was heated by air to a temperature exceeding 500 degrees and the system maintained this temperature for up to 20 hours. Scientists say that reducing the cost of this thermal energy storage system, or energy storage systems in general, increases the potential for adoption of such installations in industry and increases the likelihood of a transition to renewable energy sources.
The scientists say their practical method involves storing excess electricity generated during the day as heat and using it to heat water and homes at night. The testing phase of the technological prototype will last until June 2024.
Previously Focus said that battery production would soon require the energy of all of Sweden or Norway. However, the scientists’ study predicts that overall energy needs may decline in the future.
