Energy-Efficient Data Center Cooling and Waste Heat Recovery System

digitalPilotedTRL 8

Imagine dunking your computer parts into a special liquid that doesn't short-circuit them, but sucks away heat much better than a fan ever could. Instead of letting that heat vanish into the air, this system catches it and stores it in a high-tech thermal battery. This stored warmth can then be used to heat buildings or even generate electricity.

The business problem

What needed solving

Data centers consume massive amounts of electricity and waste valuable low-grade heat. Traditional air cooling is inefficient and costly, especially as energy prices rise.

The solution

What was built

An automated prototype combining a 40 kW immersion cooling system with a 500 kWh thermal energy storage unit using phase change materials and recycled glass insulation.

Who can put this to work

Cloud Computing
SME
Target: Edge Data Center Operator

If you are an edge data center operator dealing with high electricity costs and cooling inefficiency — this project developed an immersion cooling system that reduces Power Usage Effectiveness (PUE) below 1.1. This allows you to cut energy waste significantly compared to the industry average of 1.6.

District Heating
enterprise
Target: Municipal Energy Provider

If you are a municipal energy provider dealing with a lack of low-grade heat sources — this project developed a 500 kWh thermal energy storage unit. This allows you to capture waste heat from nearby data centers and reuse it for space heating.

Green Construction
mid-size
Target: Sustainable Building Developer

If you are a developer dealing with strict CO2 emission targets for new office hubs — this project developed a heat recovery system that can lead to CO2 savings exceeding 200 million. This integrates data center heat directly into the building's climate control.

Frequently asked

Quick answers

How much does the system cost to implement?

Based on available project data, specific pricing or implementation costs are not provided.

Is this technology ready for industrial scale?

The project is demonstrating a 40 kW data center immersion cooling system and a 500 kWh storage unit, aiming for TRL8, which is near commercial readiness.

How is the intellectual property handled or licensed?

Based on available project data, specific IP or licensing terms are not mentioned, though the project includes strategies to maximize exploitation impact.

How does this integrate with existing data center hardware?

It replaces conventional air-cooling with immersion cooling, where IT components are submerged in dielectric fluids to improve heat removal.

What is the timeline for the demonstration?

The project period runs from 2024-01-01 to 2027-12-31.
