Scientists from Texas A&M University are working on advanced “ice batteries” that can store and release thermal energy much more efficiently. So, what is the working principle of these batteries?

While ice has long been the simplest solution for keeping drinks cold, researchers are taking this idea much further. Scientists from Texas A&M University are working on advanced “ice batteries” that can store and release thermal energy much more efficiently. These studies could change the way large buildings manage their heating-cooling systems and alleviate the load on the electrical grid.

Associate Professor Dr. Patrick Shamberger from the Department of Materials Science and Engineering is leading research aimed at improving the materials used in these systems. His findings, along with his team’s, could help the technology work more effectively in real-world applications.

Shamberger says that ice battery technology has existed for years, but its performance is still largely dependent on the materials used. The team’s research focuses on finding better solutions that make the systems efficient, stable, and long-lasting.

How do ice batteries work?

Ice batteries operate on a simple logic. Water or other substances are frozen at night when electricity demand is low and prices are cheap. During the day, this stored cold energy is used to cool buildings. This both reduces the strain on the grid and lowers costs for consumers.
