Natural phase-change thermal battery for cold-climate resilience, seasonal thermal buffering and low-carbon cooling support.
POLARIS uses natural winter cold and phase-change storage to preserve thermal capacity underground and release it when cooling is needed.
Cold is captured during winter, stored in a high-density phase-change reservoir, and distributed on demand through closed-loop thermal infrastructure.
The concept supports district cooling, data centers, cold chains, agriculture, healthcare storage and renewable energy balancing.
The system logic: capture natural cold, store it efficiently, then release cooling where and when it is needed.
A closed, insulated underground reservoir with surface operations, access shafts, insulation layers and a piping network.
Potential use cases across district cooling, data centers, food cold chain, industrial processes, agriculture, healthcare and commercial refrigeration.
POLARIS is a conceptual infrastructure idea. Practical feasibility depends on climate, storage volume, insulation quality, thermal losses, ground conditions, heat-exchanger performance and operational control.
