Thermal Energy Storage

Proven thermal energy storage solutions and energy services expertise for a more resilient, energy-independent building.

How Does Thermal Energy Storage Work?

Thermal energy storage works by collecting, storing, and discharging heating and cooling energy to shift building electrical demand to optimize energy costs, resiliency, and or carbon emissions. Liken it to a battery for your HVAC system. It gives you the ability to store and recover thermal energy, as well as charge or discharge based on operational needs, utility rates/programs, availability of renewable resources, etc.

Thermal energy storage can also be used in conjunction with other comprehensive energy services, like active energy management to further optimize your energy supply and demand, essentially turning your building into a virtual power plant.

Benefits of Thermal Energy Storage

Thermal energy storage is a reliable, cost-effective solution for off-setting the inevitable utility peaks during periods of high-demand. But that’s not all. Here are some of most impactful benefits of thermal energy storage for commercial buildings:

  • Lower cooling and heating costs
  • Decarbonize
  • Improve grid and building resiliency
  • Support renewable energy sources like wind and solar
  • Ability to participate in grid capacity and demand limit revenue programs

How does Thermal Energy Storage help with Energy Efficiency?

Thermal energy storage helps with energy efficiency because it allows you to consume energy at the most cost effective times of the day. Electricity generation and transmission is usually more efficient at night when efficient base load generation is being used and ambient temperatures are lower. Reducing peak demand by using the stored heating or cooling can eliminate the use of inefficient utility peaking generators.

Thermal Energy Storage vs Electricity Storage

Buildings have thermal and electric loads and will benefit by storing both forms of energy. While electrochemical batteries are the more widely-known method of energy storage, they are really designed to store electricity specifically.

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. Here’s quick breakdown to help further distinguish between the two methods:
