Comfort Cooling


On average, U.S. buildings spend 15% of their total electricity consumption on space cooling. Let’s consider a typical building’s electric load profile (right). As a building owner with ice energy storage, you can take all of the energy used for cooling and move it off-peak, significantly lowering cost.

Unfortunately, with the current state-of-the-art technology, you can face a payback period between 8 and 9 years. That long payback period is the primary barrier to more widespread use of ice energy storage and…

…is the challenge our innovation solves!

Market Trends

If you follow the developments of popular companies such as Tesla, lithium-ion batteries in cars, homes, and grid scale installations will sound familiar. Ice energy storage may be less familiar, but the comparison below clearly demonstrates its value!

Compared to Lithium ion batteries, ice thermal energy storage provides:


Simplicity >30 years lifetime 4x lower $ Inherent Safety

Regarding the applicability of ice energy storage:

  1. In 2017, 9.6 % of U.S. electricity went into cooling buildings (EIA source). Mobilizing even 1/10th of that cooling load through ice energy storage represents more than 4 GW of potential!

  2. Active Energy’s fundamental innovation will open up the use of ice energy storage in some very important new markets. Please see our other Applications sections for more information.
