We are excited to announce the completion of the first prototype installation of our innovative bipolymer waste heat recovery system at our pilot data center. This marks a significant milestone in our mission to transform how data centers handle thermal energy.

The new prototype captures waste heat generated by IT hardware—heat that would typically be dissipated into the environment—and repurposes it for campus-wide heating solutions. Our system not only enhances energy efficiency but also contributes to sustainable building operations by reducing reliance on traditional heating methods.

Following the success of similar initiatives—such as ThermalWorks’ systems that turn server heat into carbon-neutral energy (thermalworks.com) and NTT DATA’s Berlin project delivering up to 8 MW of district heating (businesswire.com) — our bipolymer prototype stands out by leveraging proprietary materials to optimize heat transfer and control. Initial performance tests show promising results in thermal recovery rates and system reliability, even under typical data center loads.

Over the next few weeks, we’ll monitor the system’s real world performance, fine-tune control parameters, and gather comprehensive data to inform the next phase: scaling up to full-scale deployment.

This installation brings us one step closer to a future where data centers aren’t just energy consumers—they become sustainable heat hubs contributing to broader carbon reduction goals.

From 1 July 2026, the new Energy Efficiency Act (EnEfG) mandates that newly commissioned data centres with a non redundant power connection of 300 kW or more must achieve an Energy Reuse Factor (ERF) of at least 10 %. For operations starting 1 July 2027, the requirement increases to 15 %, and for those after 1 July 2028, to 20 %, to be achieved within two years after commissioning.

The aim is clear: waste heat must no longer just dissipate unused. Operators are required to channel it into their own heating networks or collaborate with local district heating providers. Germany is steering data centres toward becoming integral components of sustainable urban energy solutions.

🔧 Our Innovation: Bipolymer Waste Heat Harvesting Technology

We’re developing a breakthrough bipolymer-based solution designed to recover data-centre waste heat with 10 – 15 % efficiency — aligned perfectly with upcoming legal targets.

• Efficiency goal: 10–15 % heat recovery — ready for direct injection into thermal networks

• Pilot phase underway: We are conducting extensive real-world trials and refining the system toward market readiness

🌍 Why It Matters

• Regulatory compliance: Ensures data centres meet EnEfG ERF requirements

• Environmental impact: Reduces CO₂ emissions by replacing fossil-fuel based heating

• Economic benefit: Waste heat becomes a valuable resource that can generate revenue

With our novel bipolymer system, we don’t just intend to meet the legal standard — we aim to surpass it. The era of green data-centre heat is about to begin. Join us in shaping a sustainable digital infrastructure!

This regulatory shift presents a unique opportunity to transform data centers into active contributors to sustainable energy systems.

🔥 The Waste Heat Challenge

Data centers are notorious for their energy consumption, with a substantial amount of energy dissipated as low-grade heat, typically ranging from 50°C to 150°C. Traditional methods of capturing and converting this heat into usable energy have been inefficient and costly. However, advancements in technology are paving the way for more effective solutions.

⚙️ Poligy's Innovative Solution

Poligy has developed a groundbreaking bipolymer-based system that efficiently converts low-grade waste heat into electricity. This technology operates on the principle of differential thermal expansion, where two polymers with different coefficients of expansion are combined. When exposed to heat, the polymers bend, driving a mechanical system that generates electricity.

Key features of Poligy's solution include:

• Efficiency: Converts waste heat into electricity with an efficiency range of 4% to 15%, depending on temperature gradients.

• Cost-Effectiveness: Utilizes abundant and recyclable materials, reducing production costs and environmental impact.

• Scalability: The modular design allows for easy integration into existing infrastructure without significant modifications.

🌍 Aligning with Regulatory Requirements

The EnEfG mandates that data centers achieve an Energy Reuse Factor (ERF) of at least 10% by 2026, increasing to 15% by 2027, and 20% by 2028. Poligy's technology not only meets these requirements but also offers a pathway to exceed them, turning regulatory compliance into a competitive advantage.

🚀 Looking Ahead

As Germany continues to lead in sustainable energy initiatives, Poligy's innovative approach positions data centers as pivotal players in the green energy transition. By harnessing waste heat, data centers can reduce their carbon footprint, lower operational costs, and contribute to a more resilient and sustainable energy grid.
