A smart ice battery

Ice storage is a clean, reliable and least-cost distributed energy storage solution for the grid. Since 2005, Ice Bears have been installed in more than 40 utility services, transforming inefficient and polluting air conditioners into efficient and clean cooling systems. With a reliability record in excess of 98%, they benefit both utilities and their customers. Ice batteries improve the efficiency and resiliency of the grid, lower cooling bills and reduce carbon emissions.

Powered by ice

Ice Bear charges by making ice during off-peak hours and discharges by using the stored ice to cool buildings during peak hours. Our smart ice battery reduces peak cooling electricity by 95% for up to 6 hours a day, every day.

How it works

The Ice Bear is a smart, distributed ice battery that seamlessly integrates with a building’s cooling system and answers the needs of commercial, industrial and residential customers. Ice Bear 30, our commercial ice battery, attaches to 4-20 tons commercial AC units while Ice Bear 20, our home battery, integrates with ductwork or ductless mini-split systems inside new or existing homes.

Smart-grid enabled

Ice Bear is equipped with a smart-grid controller and bi-directional communications technology to provide real-time visibility and control.

Remote Monitoring
Ice Bear is fitted with sensors that remotely monitor the performance of each unit.

  • Coolant systems pressure
  • Ice Temperature
  • Control housing temperature
  • Outside ambient temperature
  • Ice Bear components
  • Supply and return air temperature, on either side of the air handler
  • Indoor thermostat
  • AC compressor on/off status

Remote Controls
Operating instructions and needed adjustments can be sent remotely

  • Dispatch Ice Bear to make or melt the ice
  • Set or modify charge/discharge schedule
  • Control how much cooling is provided and for how long
  • Update software and upgrade firmware to roll out new product features and fixes
  • Control and dispatch additional demand-response assets

Security
The Ice Bear network is a secure, private wireless network with end-to-end encryption. Servers and databases are located behind firewalls that use security best practices.

Control dashboard

The Control Dashboard provides cumulative and real-time system performance data from aggregated and individual Ice Bear units. It also allows customers to remotely control Ice Bear and any additional demand-response assets that are connected to it.

Why Ice Bear?

icon-smart

Smart

Two way communications allow real-time control and monitoring of each individual unit or groupings of units. Most fixes, software upgrades and firmware updates can be performed remotely. End-to-end data and network security provide additional peace of mind.

icon-reliable

Reliable

Ice Bear storage is commercially-proven. Since 2005, our smart ice batteries have logged over 34 million operating hours with a reliability record in excess of 98%. Our ice batteries were built to last and require minimal maintenance.

icon-economical

Cost-effective

Ice batteries cost less than half of lithium ion batteries of the same capacity on a life-cycle basis. They can eliminate the need for expensive peaker plants, and new transmission and distribution upgrades. Customers save up to 40% on their cooling bills too.

durable3

Durable

While chemical batteries degrade over their relatively short life, our ice batteries last at least 20 years and suffer no degradation, regardless of use. They can be fully charged and discharged everyday for up to 20 years without any capacity loss.

icon-flexible

Flexible

Ice Bear storage is available for both commercial and residential applications. Utilities can dispatch individual units, custom groupings or fleets, and schedule them for permanent load shifting or for real-time dynamic load optimization.

solar-energy

Solar-friendly

Ice storage firms solar capacity and makes productive use of solar over-generation. Unlike chemical batteries, ice batteries can work with solar for the entire life of the solar assets, and do so every day, at the full rated capacity of the ice batteries.

icon-sustainable

Sustainable

By eliminating the need for fossil-fuel “peaker” plants and supporting renewable energy, Ice storage reduces CO2 emissions by up to 40% and NOx emissions by up to 56%. Unlike chemical batteries, it does not use any hazardous or toxic material, and does not create any end-of-life disposal issues.

icon-community

Community-focused

Ice Bear storage provides air conditioning savings to businesses and homeowners, and generates long-term business opportunities for local HVAC contractors. It integrates seamlessly into the existing infrastructure and enables a cleaner, more efficient power grid for the community.

Installation

Ice Bear is easy to install and seamlessly integrates into a building cooling system

  • Ice Energy works with select certified HVAC contractors in your area. We supervise and coordinate the installation to give you peace of mind.
  • In residential applications, Ice Bear simply replaces the compressor unit that sits outside the home.
  • For commercial and industrial buildings, Ice Bear attaches to one or more 4-20 ton commercial AC units and can be installed on rooftops or on the ground.
