As data centers continue to expand to support AI, high-performance computing, and cloud services, operators face increasing pressure to improve energy efficiency and sustainability.
One of the most significant developments in recent years has been the adoption of Direct Liquid Cooling (DLC). By cooling processors and accelerators directly with liquid, modern DLC systems can operate at substantially higher coolant temperatures than traditional air-cooled infrastructure.
This technological shift creates a unique opportunity: transforming waste heat into valuable electrical power.
The elevated coolant temperatures generated by modern DLC systems are now compatible with Eureka Energy Systems’ low-temperature Organic Rankine Cycle (ORC) technology.
Unlike conventional waste heat recovery solutions, Eureka’s ORC system can utilize the available thermal energy directly, eliminating the need for energy-intensive heat pumps to raise the temperature before conversion.
This delivers several key benefits:
As AI-driven computing clusters continue to increase in scale and power density, the amount of recoverable thermal energy grows accordingly.
By integrating Eureka Energy Systems low-temperature ORC technology, data centers can convert a portion of their waste heat into on-site electricity generation, reducing overall energy consumption and improving facility sustainability.
Instead of viewing waste heat as a by-product, operators can transform it into a strategic energy resource.
The combination of Direct Liquid Cooling and low-temperature ORC technology represents a major step forward in data center energy optimization.
By recovering energy directly from DLC cooling loops—without requiring heat pumps—operators can maximize energy utilization, lower carbon emissions, and improve the overall economics of their facilities.
Eureka Energy Systems is helping redefine waste heat recovery by enabling efficient power generation from low-temperature heat sources, supporting a more sustainable and energy-efficient future for the global data center industry.

Eureka Energy Systems has started work with it’s seed stage funding. The aim is to attract new capital in a range from 0,7-2,0 M€. This will facilitate Eureka’s first commercial installation of it’s unique low temperature ORC system on an identified customer site. The installation will bring substantial savings to the customer through behind-the-meter electricity production from waste heat and CO 2 emission abatement. The expected pay-back for the customers investment is less than 3 years.

Eureka has defined Poland and Polish companies and strategic partners as important cornerstones for development and enhancement of our possibilities to grow and expand.
The Polish market holds great possibilities for profitable growth in Renewable Energy and with a strategic position inside the EU Poland represents a big potential for Eureka in the transition from fossil energy to a net zero position.
“We see the transformation of the energy system in Poland as a great opportunity for us and the EU to reach ambitious objectives in the transition from fossil fuels to Renewable Energy and sustainability, says Rolf Hasselström – Chairman of Eureka Energy Systems AB”
