Thermal energy storage — ice-bank, PCM and chilled-water TES for cooling
Ice-bank, phase-change material (PCM), chilled-water and eutectic thermal storage — sized to shift refrigeration and HVAC load away from peak tariffs, buffer solar generation and cut installed chiller capacity. ColdMatch benchmarks TES vendors and EPCs on capacity (RTh), round-trip losses, footprint and integration with existing plant.

Thermal Energy Storage — frequently asked
How much can thermal storage cut cooling bills?
Sites on time-of-use tariffs typically cut cooling OPEX 20–40% by shifting chiller run-time to off-peak, plus 10–25% demand-charge savings.
What's the payback on an ice-bank TES retrofit?
In markets with a 3–5× peak/off-peak tariff spread, ice-bank TES retrofits pay back in 3–6 years; solar-buffered TES often shorter with grants.
Can TES replace batteries in a solar cooling project?
For cooling-only duty, yes — ice-bank and PCM TES deliver longer life, lower CAPEX per stored cooling kWh, and no thermal-runaway risk vs lithium.
How is TES integrated with existing chillers?
TES is typically added on the chilled-water loop with a dedicated charge chiller or by oversizing an existing chiller — ColdMatch specs the integration and benchmarks vendors.
