Thermal storage applications

Thermal energy storage for buildings, real estate and industry

ThermoReserve creates thermal flexibility by storing energy when it is available and delivering useful heat when the site needs it.

Our current market focus is commercial buildings and real estate, with industrial process heat and local energy systems as expansion pathways.

ThermoReserve thermal energy storage connecting grid electricity, renewable electricity and recoverable heat with commercial buildings, industrial heat and local energy systems.

Where it fits

Start where thermal flexibility solves a measurable site problem

ThermoReserve prioritises applications with significant heat demand, a clear timing mismatch and a practical route to integration.

Current market focus

Commercial buildings & real estate

Add a controllable thermal reserve to properties where heating demand, power peaks, renewable generation or electrification create a reason to shift energy in time.

  • Commercial properties and portfolios
  • Institutional and public buildings
  • Sites with PV, heat pumps or increasing electrical loads
Expansion pathway

Industrial & process heat

Store electricity or recoverable heat for later delivery to suitable industrial thermal duties at defined temperatures and operating periods.

  • Process and utility heat
  • Electricity-to-heat shifting
  • Recovered-heat utilisation
System-scale pathway

Local & district energy

Add modular thermal capacity where local generation, heating demand and network conditions create value from energy shifting and thermal buffering.

  • Local energy systems
  • Campus and multi-building applications
  • District heating and cooling pathways

Potential site value

The value comes from what storage enables

Thermal storage is relevant when moving energy in time improves how the site uses electricity, renewable generation, recovered heat or available thermal capacity.

Shift heating demand Separate part of heat production from the exact time the heat is consumed.
Reduce peak exposure Use stored heat to reduce dependence on immediate thermal production during high-load periods.
Use more available energy Retain suitable renewable electricity or recoverable heat for later useful delivery.
Support electrification Add thermal flexibility where new electrical loads would otherwise increase simultaneous site demand.

Application fit

Is thermal energy storage suitable for your site?

Not every site needs storage. The strongest opportunities combine a measurable thermal load, a useful charging window and a clear reason to shift energy from one period to another.

The application should define the storage system, including its temperature, power, duration, charging method and site interface.

Thermal demand Is there enough measurable heat demand to justify storage?
Temperature What temperature and useful thermal output does the site require?
Timing Is energy available at a different time from when heat is needed?
Utilisation Will the storage cycle often enough to create meaningful value?
Integration Is there a practical route to connect the storage to the site?
Evidence Can technical and commercial performance be measured against a baseline?

Validating the building pathway in Gothenburg

ThermoReserve is progressing from stand-alone thermal-storage testing toward real-site integration within the Varis Commercial Building FlexHub. The pilot provides a measured reference for building heating and thermal flexibility. Follow the pilot →

Real commercial site Validation in an operating property rather than only a laboratory environment.
Measured thermal performance Testing focuses on charging, retention, useful heat delivery and operating behaviour.
Integration learning Interfaces, controls and site operation are validated as part of the reference pathway.
Replication logic Results are intended to support future building and portfolio applications.
