Thermal Batteries are also known as heat batteries and considered a type of thermal energy storage (TES) systems that  captures and stores heat/cold from either a traditional or non traditional  source such as manufacturing or industrial processes, solar, etc..  It then stores the heat/cold in various mediums depending on the battery type.  The mediums used in TES can vary  such as, water, molten salts, concrete, rocks or to more efficient thermal batteries that use phase change materials and other materials. Thermal battery applications are growing and Forbes noted “Thermal Batteries Could Cut U.S Industrial Heating Power Costs In Half”. (1) 

Thermal batteries can also range in temperatures and can be used for a variety of applications  from large solutions that help stabilize the electric grid to an alternative source of energy from burning fossil fuels to small cooling packs.    

Similarly, CoreTherma thermal batteries are helping revolutionize energy storage by offering a solution that parallels the everyday chemical batteries we know and rely on. Like traditional batteries that hold energy for convenient use, CoreTherma batteries are built for the same purpose but with a significant twist. Instead of storing electricity, our innovative technology stores thermal energy, whether it’s hot, cold, or at ambient temperatures.  

Imagine harnessing the power of excess solar or wind energy and preserving it for future use—CoreTherma thermal batteries use phase change materials and do exactly this, but with thermal energy. They capture surplus heat or cooling that would typically go to waste during daily operations or from leveraging the natural temperature swings between day and night.  

A Phase Change Material, by design, goes through a transformation from a solid to a liquid or back again, and during those transitions, it can either absorb vast amounts of heat or give up vast amounts of heat. Phase Change Materials (PCMs) are not new or transformative; energy storage through phase transitions occurs in countless natural and man-made processes every day. For example, ice serves as a well-known example of a PCM.   What truly sets the PCM materials CoreTherma uses apart is its unwavering commitment to environmental safety and tailored solutions that meet specific needs.  CoreTherma uses state-of-the-art PCMs for reliable performance that prioritizes safety and sustainability. 

One of the standout advantages of its thermal energy storage is the elimination of energy loss associated with converting electricity back and forth into heat or cooling via heaters and chillers. With CoreTherma the energy is ready to be used directly for heating or cooling, delivering increasing efficiency. In addition, in some applications, this strategy allows the storage of thermal energy during off-peak hours, ensuring its availability during peak-hour demands.  

By selecting CoreTherma, you are not just selecting an energy storage solution; you are embracing a smart, efficient way to
manage energy that can lead to cost savings, reduced environmental footprint and/or increased resiliency. 

We specialize in innovative thermal energy storage solutions designed by experts in real estate and facility management, specifically designed for the built environment. Our purpose is to develop products that are not only easy to install but also require minimal maintenance, simple to operate, and are environmentally friendly—all while maximizing space with their compact designs.
