Geo-HEP Seasonal Storage

Using heat and cooling
when they're needed

Store thermal energy when it is available—and use it when it is needed.

The Geo-HEP seasonal storage system is being developed as a standalone thermal storage system. It is designed to absorb heat or cold, store it for an extended period, and release it at a later time as needed.

Unlike the high-performance energy pile, the focus here is not on short-term thermal buffering, but rather on targeted, longer-term, and seasonal storage.

The Geo-HEP seasonal storage system is currently in the prototype phase. The values calculated by computer are being verified using actual performance data. The results will be published once the testing is complete and the system has been approved.

The System Principle at a Glance

How the Geo-HEP Seasonal Storage System Works

01

Absorb heat or cold

Capture available thermal energy from buildings, processes, or other sources.

02

Save for a longer period of time

Store heat or cold in a targeted manner and shift it over time to match availability with demand.

03

Use again later

Provide stored thermal energy to buildings, facilities, or processes as needed.

Storing and Using Heat and Cooling According to Demand

The Geo-HEP seasonal storage system is designed to accommodate varying thermal requirements within a single system. Heat and cold can be stored and made available again as needed.

Storing Heat

Excess heat can come, for example, from cooling buildings in the summer, industrial processes, or solar thermal systems, and can be stored for later use.
Depending on the temperature,the stored heat can be reused directly or in conjunction with a heat pump.

Storing Cold

Cold can also be stored in a targeted manner over extended periods and made available again at a later time as needed.
This is particularly useful for applications with high, regular, or predictable cooling demands.

What makes the Geo-HEP seasonal storage system unique?

  • Long-Term Storage

    Thermal energy is specifically retained to ensure availability over extended periods.
  • Heat and Cooling

    The concept is designed for both heat and cold storage.
  • Thermal Stratification

    Different temperature levels should remain as separate as possible within the storage system.
  • Modular Design

    Multiple storage modules can be combined into a storage array tailored to specific project requirements.

Modular and project-specific

The number and configuration of the storage modules depend on energy requirements, available space, temperature levels, and the specific project conditions.

The Geo-HEP seasonal storage system is currently in the prototype phase. The values calculated by computer are being verified using actual performance data. The results will be published once testing is complete and the system has been approved.

Could a Geo-HEP seasonal storage system be a good fit for your project?

Whether a seasonal storage system is a good fit for your project depends primarily on when thermal energy is available, when it is needed, and what quantities and temperature levels are to be stored.

 

Is there usable heat or cooling?

For example, from building cooling systems, industrial processes, or other thermal sources.

Should heating and cooling be available on a flexible basis?

The layered principle is designed to provide heat or cooling in parallel, as needed.

Is it possible to integrate a suitable storage array?

Sizing and system design are developed on a project-by-project basis.

In what situations might seasonal storage be a good option?

Building Cooling

Absorb summer heat and make it usable again later.

Industry & Processes

Store process heat and waste heat for later thermal use.

Heat Supply

Use stored heat directly or with a heat pump.

Cooling Applications

Providing cooling for applications with high or predictable cooling requirements.

Is a Geo-HEP seasonal storage system a good fit for your project?

Whether a seasonal storage system is a good fit for your project depends primarily on the available heat and cooling sources, the required temperature levels, the thermal loads, and the project-specific conditions.
