Trane Thermal Energy Storage

Thermal Energy Storage

The proven strategy for more cost-effective, sustainable heating and cooling systems. Now more affordable than ever with an up-to 50% investment tax credit.

Thermal Battery Cooling System

Both new and existing buildings need more affordable, flexible ways to heat and cool based on energy availability. The answer is Thermal Energy Storage—which acts like a battery in a heating and cooling chiller plant to help improve energy, cost and carbon efficiency. Besides offering a great ROI, adding thermal energy storage is highly affordable thanks to recent tax incentives.

Trane is your personal thermal energy storage provider, combining leading technology, controls knowledge and systems expertise based on your unique building circumstances. Your local team can collaboratively guide you through a custom, seamless implementation based on your unique goals.

Why Choose Trane Thermal Energy Storage?

Through years of research and thousands of installations, Trane has identified water as a very effective material for storing thermal energy for later use. This makes thermal energy storage an optimal means for a chiller plant to collect, store, recover and discharge heating and cooling energy. That’s just the start of what makes it such a powerful solution.


Inflation Reduction Act Incentives

For the first time in its 40-year existence, thermal energy storage now qualifies for federal incentives. Thanks to the $370+ billion Inflation Reduction Act (IRA) of 2022, thermal energy storage system costs may be reduced by up to 50%. Between the IRA’s tax credits, deductions, rebates and more, a thermal energy storage system may cost significantly less than a conventional system.

Visit Trane Design Assist

Made with durable polyethylene, yours can be implemented into a new building or retrofitted when replacing a chiller plant. All you need is space for the tanks, which can go virtually anywhere: inside, outside, on a roof, in a parking garage, even buried.

Thermal Energy Storage Tanks

CALMAC® Energy Storage Tank Model C

These versatile second-generation tanks are ideal for larger commercial and institutional buildings, making siting and installation easy. Designed with a 20% smaller footprint requirement, Model C tanks can be bolted together to eliminate external piping and reduce installation time and costs.

CALMAC® Energy Storage - Model A Tanks

Ideal for small installations since their introduction in 1979, our Classic Model A tank has been upgraded to the 100% welded PE internal heat exchanger design. They’re designed for individual connection with distribution piping.

Integrated Thermal Energy Storage Systems

Thermal Battery Storage Systems

Trane Thermal Battery™ systems are premier HVAC plants that provide a distributed resource for our changing grid. Their ability to store thermal energy enables your building to reliably modify HVAC operations to optimize for carbon reduction or energy cost savings.

Glycol® Management System

A Glycol Management System (GMS) makes solution mixing easy by maintaining the proper volume of coolant in a building's circulating loop.

CALMAC® Plate Heat Exchanger

Plate Heat Exchangers are ideal for avoiding cross-contamination in confined spaces. 


Thermal Energy Storage and Electricity Storage

All types of energy storage are needed for a low-carbon future, and each technology has its own best use case. For maximum efficiency and cost-effectiveness, it’s important to store energy in the same form in which it will be consumed. That means using electrochemical storage to meet electric loads and thermal energy storage for thermal loads.

Electric storage is essential for powering elevators, lighting and much more. However, when it comes to cooling or heating, thermal energy storage keeps the energy in the form it's needed in, boosting efficiency tremendously compared to other forms of electricity.

 

Compared to electricity storage, thermal energy storage also offers:
