Iceheart™ develops patented ice-based thermal energy storage (TES) technology that turns ice into a “cold battery” for reliable, long-duration cooling. Our systems deliver stable cooling with low power demand and the flexibility to run on solar and low-cost electricity, even in hot and off-grid environments.

Cooling is energy-hungry and vulnerable. Cold storage, data centers and medical cold chains depend on stable cooling, yet rising energy prices, grid instability and diesel dependency make traditional systems expensive and fragile.

Iceheart™ stores energy as ice when power is available (grid or solar) and releases it as cooling when needed. By combining thermal energy storage with passive thermosyphon technology, we provide long-duration cooling that can shift consumption to solar hours and off-peak tariffs, reduce diesel use and improve system resilience.

Key benefits:
• Reduces energy costs and peak loads for cold rooms and process cooling.
• Enables off-grid or weak-grid operation with solar PV and small inverters.
• Cuts diesel use in cold chains and remote sites.
• Improves resilience during outages – cooling continues even when power fails.

We focus on:
• Cold storage & cold rooms
• Cold transport & logistics
• Data center & telecom cooling
• Medical and humanitarian cold chains
• Military & off-grid applications

Iceheart™ is currently working with partners in Europe, the GCC, Africa and the US to deploy pilot and demo systems in cold storage, logistics and harsh-climate applications.

We partner with cold-chain operators, solution integrators and technology providers through pilots, joint development and licensing.
