Thermal energy and heat pump technology solution for low-carbon heating in extreme cold

Trane Technologies, a global climate innovator, has introduced its Thermal Battery StorageSource Heat Pump System – a first-of-its-kind solution to advance electrified, low-carbon heating in buildings, including in climates below zero degrees Fahrenheit.

The Thermal Battery Storage-Source Heat Pump System brings heating and cooling into one electric
solution and can be three times more efficient than traditional heating methods. Commonly referred to as ice storage, the thermal energy storage ice tanks serve as energy reservoirs, allowing a building
to shift its heating and cooling electricity demands to off-peak hours. This enhances energy efficiency and reduces expenses. Furthermore, thermal energy storage systems are now eligible for substantial tax
credits under the Inflation Reduction Act.

The innovative system converges proven technologies to accelerate building decarbonisation:
• Thermal energy storage ice tanks reclaim and store excess building heat like a battery. They utilise a reverse vapour compression cycle for optimal efficiency in air-to-water heat pumps to extract heat from the air outside to warm the building.
• All-electric chiller heaters recover the excess building heat from the ice tanks to expand air-to-water
heat pump applications further into dense urban environments and cold climates.
• Intelligent controls, maximising occupant comfort and energy efficiency.
• Dave Regnery, chair and CEO of Trane Technologies, said, “We pioneered the use of ice tanks in
thermal storage for cooling, and now we are integrating these proven technologies into an industry-first
solution for electrified heating. Through relentless innovation, our team continues to leverage creative new solutions to accelerate the decarbonisation of the built environment. As we scale this technology, we can dramatically reduce emissions for a more sustainable world.”

Through bold, industry-leading action and innovation, Trane Technologies is advancing its 2030 sustainability commitments, including the Gigaton Challenge – a pledge to reduce customer greenhouse gas emissions by 1 billion metric tons (or one gigaton) – and its pledge to be net-zero by 2050. The
Science Based Targets Initiative (SBTi) has externally validated the company’s emissions reduction targets.
