Ice Energy Storage

The ice energy storage system is an attractive heat source for brine-to-water heat pumps. It bundles the energy from ambient air, solar radiation, precipitation and the ground.

  • Suitable for large-scale systems
  • Energy from ambient air, solar radiation, precipitation, soil
  • Comprehensive range of services
  • Low regulatory requirements

Features

Low Regulatory Requirements

The system can also be installed in water protection areas, offering high planning flexibility.

Highly Efficient Operating Modes

Energy is stored and released using the latent heat of crystallisation, enabling efficient year‑round operation.

CO₂‑Free Operation

When combined with monovalent heat pump systems and a CO₂‑free energy mix, the system operates without direct emissions.

Combination of Four Energy Sources

High efficiency is achieved by utilising: Ambient air Solar radiation Precipitation Soil energy

Control / Integrations

Integrated System Control

Intelligent control coordinates heat pump, ice storage, and solar‑air absorbers for maximum efficiency.

Optimised Heat Pump Integration

Designed to work seamlessly with large‑scale heat pump systems for heating and cooling.

Seasonal Energy Management

Enables efficient heat extraction in winter and cold utilisation in summer.

Flexible System Integration

Suitable for integration into:

Commercial heating and cooling systems
District energy solutions
Hybrid renewable energy concepts

Long‑Term Operational Reliability

Simple system design with minimal moving parts ensures high reliability and low maintenance.
