Cooling and refrigeration systems are essential for buildings, vehicles, and industry—but the dominant technology behind them has changed little for decades. Most HVAC systems still rely on vapor‑compression compressors and chemical refrigerants, which consume significant energy and face tightening environmental regulation.
Freiburg‑based climate‑tech startup Qurie is working on a different approach: solid‑state electrocaloric cooling that eliminates conventional refrigerants and compressors. The company’s technology originates from research around the Fraunhofer Institute for Physical Measurement Techniques (Fraunhofer IPM) and aims to deliver quieter, more efficient cooling systems that are easier to integrate into modern electrified infrastructure.
The problem with conventional HVAC cooling
Most air conditioners, refrigerators, and heat pumps use vapor‑compression cycles. These systems rely on compressors and circulating refrigerants to move heat from one place to another. While effective, the approach has two major challenges:
Environmental impact: Many systems use refrigerants that can harm the climate if leaked. New technologies that eliminate these chemicals are increasingly attractive as regulations tighten.
Energy consumption and mechanical complexity: Compressors require moving parts and significant electricity to operate.
Research programs at Fraunhofer highlight that solid‑state heat pumps based on caloric materials can operate without harmful refrigerants, making them a promising alternative for sustainable heating and cooling systems.

What is the short answer to "How Qurie Is Building Refrigerant‑Free Cooling With Electrocaloric Technology"?
Freiburg‑based startup Qurie is developing electrocaloric heat‑pump technology—a solid‑state cooling approach that avoids harmful refrigerants and could replace compressor‑based HVAC systems if it scales successfully.

Freiburg‑based startup Qurie is developing electrocaloric heat‑pump technology—a solid‑state cooling approach that avoids harmful refrigerants and could replace compressor‑based HVAC systems if it scales successfully. The technology originates from Fraunhofer research into electrocaloric materials that heat and cool when electric fields are applied or removed, enabling refrigeration without traditional vapor‑compression cycles.
What should I do next in practice?
Early funding from investors including High‑Tech Gründerfonds and tech‑transfer initiatives linked to the German research ecosystem aims to help move the technology from lab demonstrators to commercial products.
Qurie’s approach is based on the electrocaloric effect—a physical phenomenon in certain materials where temperature changes occur when an electric field is applied or removed.
When an electric field is applied to an electrocaloric material, its internal electric dipoles align and the material warms up. When the field is removed, the material cools below its original temperature. By cycling this process and transferring heat between hot and cold sides, the system can function as a heat pump or refrigeration device.
This approach differs from conventional HVAC systems in several ways:
Cooling is generated by electric‑field‑driven materials rather than refrigerant compression.
The system can be solid‑state with fewer moving components.
It can operate with harmless fluids such as water for heat transfer, rather than high‑global‑warming refrigerants.
Fraunhofer researchers have demonstrated prototype electrocaloric heat‑pump systems through projects such as the ElKaWe flagship program, where multiple institutes collaborated to develop materials, device architectures, and demonstrators for next‑generation cooling.
The role of Fraunhofer research and system design
Qurie’s technology builds on this research ecosystem around caloric cooling. Fraunhofer IPM’s caloric systems program focuses on developing heat pumps and cooling systems based on electrocaloric, magnetocaloric, or elastocaloric materials, integrating material science with system engineering.
The research explores new heat‑transfer designs—including approaches related to advanced heat‑pipe concepts—to efficiently move heat between the hot and cold sides of solid‑state devices. Efficient thermal transfer is critical because it determines how effectively electrocaloric materials can deliver usable cooling in real systems.
Electrocaloric heat pumps developed in these research programs aim to combine:
high efficiency
refrigerant‑free operation
compact and quiet solid‑state designs
If these goals translate into commercial products, they could represent a major shift away from compressor‑based HVAC technologies.
Where electrocaloric systems could be used first
Electrocaloric cooling is still emerging, but researchers already identify several potential applications. Fraunhofer programs developing the technology point to uses such as:
Building heating and cooling systems
Domestic and industrial refrigeration
Automotive air‑conditioning systems, including for electric vehicles
These sectors share two traits: large energy demand for cooling and growing pressure to eliminate environmentally harmful refrigerants.
For startups like Qurie, early commercialization often focuses on applications where compact size, quiet operation, or efficiency advantages provide clear benefits compared with conventional compressor systems.
Why investors are backing deep‑tech cooling startups
Commercializing solid‑state cooling technology requires significant time and capital because it sits at the intersection of materials science, engineering, and manufacturing. Early‑stage investors connected to Germany’s research ecosystem often support such projects.
For example:
High‑Tech Gründerfonds (HTGF) is one of Europe’s most active seed investors in high‑tech startups and focuses on early‑stage technologies with strong research origins.
Germany’s Tech‑Transfer Fund TT49 supports science‑based startups emerging from research organizations and helps them bridge the long development cycles typical of deep‑tech ventures.
The HTGF program itself operates within a federal innovation framework designed to strengthen research commercialization and startup formation.
Funding from these types of investors can support the critical early steps needed to move electrocaloric cooling from laboratory prototypes to manufacturable systems.
The bigger picture for HVAC innovation
Heating and cooling account for a large share of global energy use, and improving efficiency in this sector is widely seen as essential for the energy transition. Heat pumps themselves are already a key technology for sustainable climate control when powered by renewable electricity.
Electrocaloric systems represent one of several emerging solid‑state cooling approaches being explored as potential successors to compressor technology. While the technology is still developing, progress in materials science, thermal management, and device engineering suggests that refrigerant‑free cooling could become increasingly viable in the coming decade.
If startups like Qurie succeed in turning research prototypes into scalable products, they could help reshape how buildings, vehicles, and appliances manage heat—without relying on the compressors and refrigerants that dominate today’s HVAC systems.
