If you are a data center operator dealing with high cooling costs and new EU energy regulations — this project developed a thermochemical storage system that captures waste heat. It allows you to store energy produced in summer for winter use, helping you meet mandatory heat recovery thresholds.
Seasonal Heat Recovery and Storage for Data Centers to Power District Heating
Imagine a giant battery, but instead of storing electricity, it stores heat using special chemicals. Data centers produce a lot of warmth that usually goes to waste, especially in summer when nobody needs it. This system captures that warmth and saves it for winter, acting like a thermal warehouse for cities.
What needed solving
Data centers produce massive amounts of low-temperature waste heat that cannot be used immediately because the demand for heating occurs in winter, while heat is produced year-round. Current infrastructure lacks the ability to store this heat seasonally or transport it efficiently to city networks.
What was built
A seasonal thermal storage system using thermochemical materials integrated with high-temperature heat pumps, including a 'Heat on Wheels' mobile storage solution.
Who needs this
Who can put this to work
If you are a utility company dealing with a lack of sustainable heat sources for city buildings — this project developed a way to integrate data center waste heat via high-temperature heat pumps. This provides a steady, low-carbon heat supply for the building stock.
If you are a manufacturer dealing with the need for specialized industrial heating equipment — this project developed a system integrating heat pumps with thermochemical materials. This creates a new market for high-temperature upgrades of low-grade waste heat.
Quick answers
What is the estimated cost or price of the system?
Based on available project data, specific pricing is not provided, but the project aims to develop 'cost-effective' and 'cost attractive' seasonal storage solutions.
Can this be deployed at an industrial scale?
Yes, the project includes a real-world demo site in Bulgaria and pre-feasibility studies for 10 additional sites across Europe to assess scalability.
How is the intellectual property or licensing handled?
Based on available project data, specific licensing terms are not mentioned, but the project involves 14 partners including 9 industry players who will co-develop the solutions.
Which regulations drive the need for this technology?
The Energy Efficiency Directive (EED), Renewable Energy Directive (RED), and the EU Taxonomy Regulation are making heat recovery mandatory above certain thresholds.
How does the system integrate with existing city infrastructure?
It uses high-temperature heat pumps to upgrade low-grade heat and offers both fixed and mobile ('Heat on Wheels') storage to overcome direct connection hurdles to district heating networks.
Who built it
The consortium is heavily industry-driven, with 9 industrial partners (64% of the total) and 5 SMEs, indicating a strong focus on commercial viability rather than pure research. With 14 partners across 7 countries, the project has a broad European footprint, combining the technical expertise of 2 universities and 2 research centers with the practical deployment capabilities of energy and digital infrastructure companies.
