Modular Thermal Energy Storage for Reducing Peak Electricity Costs in Buildings

energyTestedTRL 5

Imagine a giant thermal battery for your building that stores heat or cold instead of electricity. It lets you 'charge' the system when power is cheap or from the sun, then use that stored energy later to keep the rooms comfortable. It's like a smart thermos that helps you avoid paying high prices during peak electricity hours.

The business problem

What needed solving

Buildings face high electricity costs due to peak demand and the intermittent nature of renewable energy. Current HVAC systems lack the flexibility to store thermal energy efficiently over long periods.

The solution

What was built

A modular, plug-and-play thermal energy storage system featuring a closed-loop TCM reactor, PCM insulation, ice storage, and an advanced heat pump with a digital control system.

Who can put this to work

Construction
mid-size
Target: HVAC System Integrators

If you are an HVAC integrator dealing with high peak-load demands in new buildings — this project developed a plug-and-play thermal storage system that reduces electricity load peaks. It allows buildings to store heating and cooling energy for at least four weeks.

Energy
enterprise
Target: Smart Grid Operators

If you are a grid operator dealing with intermittent renewable energy and grid instability — this project developed a digitally controlled modular storage system. It enables electricity load shifting to stabilize the network using distributed micro-storage grids.

Manufacturing
any
Target: Heat Pump Manufacturers

If you are a heat pump manufacturer dealing with efficiency losses during charging cycles — this project developed an advanced heat pump integrated with PCM thermal buffers. This increases overall performance during the thermal charging process.

Frequently asked

Quick answers

What is the cost or price of the system?

Based on available project data, specific pricing is not listed, but the project focuses on demonstrating cost-effectiveness, affordability, and Life Cycle Cost Analysis (LCCA) to ensure the system is competitive.

Can this be scaled for industrial use?

The system is designed as a modular and plug-and-play solution, which suggests it can be scaled by adding more modules to meet different building or grid requirements.

Who owns the IP and how is licensing handled?

Based on available project data, licensing details are not provided; however, the consortium includes 10 industry partners and 4 SMEs who are likely involved in the exploitation of the developed technology.

How does it integrate with existing electricity grids?

The system includes a dedicated control system that adapts to energy production and user requirements, allowing it to function within smart electricity grids for load shifting.

What is the timeline for market availability?

The project period runs from 2023-01-01 to 2026-12-31, suggesting that fully validated commercial versions would likely emerge toward the end of 2026.

Consortium

Who built it
