Cold Storage Powered by the Sun. Guaranteed Stable Temperature, 24/7.
Cold storage facilities are among the most energy-intensive industrial assets, operating 24/7 with strict temperature stability requirements. Sun Ice Energy transforms conventional refrigeration into a solar-powered thermal energy storage system using patented PCM (Phase Change Material) thermal energy buffers. The result: lower operating costs, reduced grid dependency, and guaranteed temperature stability.
CORE VALUE
Protect your inventory and your bottom line. Sun Ice transforms cold storage into a clean, cost-controlled asset powered primarily by solar energy. Operating costs and carbon footprint are significantly reduced, with the electrical grid acting only as a silent backup for ultimate peace of mind.
Why Solar Thermal Storage for Cold Chain?
Refrigeration can represent more than 50% of total facility energy consumption in cold chain logistics. By storing renewable energy as cold through controlled PCM freeze–melt cycles, facilities gain energy resilience, peak load reduction, and long-term cost stability.
- Reduce peak demand charges through thermal load shifting
- Stabilize operating costs against volatile electricity pricing
- Enhance refrigeration resilience during grid instability
- Support ESG, sustainability, and net-zero carbon goals
Near Zero Energy with Temperature stability (±0.5 °C).
HOW DOES IT WORK
Generate & Cool
Your on-site solar panels serve as the primary power source. This renewable electricity simultaneously: Powers the chillers to handle real-time cooling demand (countering infiltration heat, equipment loads, door openings, etc.) and Charges the Ice Wall thermal storage buffers by freezing the Ice walls, building a reserve of stored cooling capacity
Discharge On Demand
When solar power is unavailable—at night, during cloudy periods, or peak tariff windows—the Ice Wall seamlessly releases stored cooling energy to maintain precise temperature stability, minimizing or eliminating the need for grid electricity.

F.A.Q
Sun‑Ice stores thermal energy, not electricity.
This makes it:
- More efficient for cooling applications
- Longer‑lasting (batteries have a limited life cycle for daily storage)
- Lower‑maintenance
- Safer (no lithium, no “run away” risk)
- More cost‑effective for large cooling loads
Sun‑Ice is integrated during the building’s design and construction phase.
We work with architects, engineers, and contractors to ensure the system is sized correctly and installed as part of the building’s cooling infrastructure.
Sun‑Ice systems are currently deployed across Asia, with global expansion underway.
Sun‑Ice uses solar energy to freeze a thermal energy storage buffer during the day.
That stored cooling is then released to keep the building comfortable at night or during cloudy periods.
No electrical batteries are required when used with Grid support.
Yes — but only during a major renovation where the building is taken back to its structural frame with state of the art insulation and ventilation.
Sun‑Ice is primarily designed for new construction, where it can be fully integrated into the building from the start.
