Why Choose Trane Thermal Energy Storage?

Through years of research and thousands of installations, Trane has identified water as the most effective phase change material for storing thermal energy for later use. This makes thermal energy storage the premier 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 can be reduced by up to 50%. Between the IRA’s tax credits, deductions, rebates and more, a thermal energy storage system can cost significantly less or can cost far less than a conventional system.

Tax exempt organizations such as schools and local governments can now get payments direct from the IRS.
Engineers can be tax incentive recipients for projects involving tax-exempt organizations like schools and federal buildings

One Trane thermal energy storage tank offers the same amount of energy as 40,000 AA batteries but with water as the the phase change material
Trane thermal energy storage is proven and reliable, with over 1 GW of peak power reduction in over 4,000 installations worldwide
