Qnetic Builds World's Largest Test Facility for Flywheel Energy Storage and Assembles First 200-kWh Prototype

According to the company, it has reached two important milestones on the path to commercializing its mechanical energy storage technology.

Shanghai/New York. The energy technology company Qnetic has begun construction of a test facility for flywheel energy storage at its technology center in Shanghai. According to the company, the facility will be the world's largest test facility specifically designed for flywheel energy storage. At the same time, assembly of the first industrial-scale 200-kWh prototype, dubbed "Pulsar," has begun.

Test Facility for Technology Validation

The test facility is intended to validate the performance, safety, and reliability of the next generation of flywheel energy storage systems. Earthwork and foundation work are currently underway. Once construction is complete, the Pulsar system will be installed and tested under real-world conditions. According to the company, the facility was designed in collaboration with an engineering partner specializing in high-speed rotational test benches.

According to Qnetic, the high amount of energy stored in the flywheel places special demands on the safety and containment of the test facility.

Mechanical Energy Storage Without Electrochemical Processes

Unlike battery storage systems, Qnetic does not store energy electrochemically but rather as rotational energy in a flywheel. A carbon-fiber rotor spins at very high speeds on magnetic bearings inside a vacuum chamber. When needed, the stored energy is converted back into electrical energy via a generator.

According to the company, this operating principle enables a long service life with minimal aging, as well as a high number of charge and discharge cycles. At the same time, the technology is designed to operate without critical battery raw materials.

"With these milestones, we are reaching an important point on our journey from technology development to commercialization," says Michael Pratt, CEO of Qnetic. "The construction of the test facility and the installation of our first Pulsar system lay the groundwork for validating our technology under industrial conditions and preparing for its rollout to customers."

Focus on Cost-Effectiveness and Supply Chain

According to the company, the key advantage of the technology lies in its long-term cost-effectiveness. Thanks to the mechanical storage principle, the systems are expected to be able to be charged and discharged significantly more frequently than conventional battery storage systems without experiencing comparable degradation.

In addition, Qnetic sees advantages in its supply chain strategy. The flywheel energy storage systems are based on materials available worldwide, such as carbon fiber, steel, aluminum, and copper. Compared to battery storage systems, whose cell production is currently largely concentrated in China, the company believes this approach contributes to a more diversified and resilient supply chain.

Applications Ranging from AI Data Centers to Microgrids

The 200-kWh Pulsar system is designed for use in AI data centers, for time-shifting renewable energy, for grid stabilization, in microgrids, and for industrial power supply concepts.

In June 2026, Qnetic also unveiled the concept of "AI-Grade Energy Storage" for AI data centers, where electricity demand can fluctuate significantly within a very short period of time.

According to the company, the technology is particularly well-suited for applications where a long service life, a high number of charge and discharge cycles, and predictable lifecycle costs are critical. In these areas of application, Qnetic sees the potential to supplement or partially replace lithium-ion batteries.

Financing and Outlook

According to the company, Qnetic completed a financing round in March 2026 under the U.S. Regulation Crowdfunding (Reg CF). The company states that it has already raised capital through several funding rounds and intends to further expand its capital base as part of its growth strategy.

In addition, Qnetic reports having non-binding letters of intent (LOIs) with potential customers, including Arevon. According to the company, it also has research and technology partnerships with the Electric Power Research Institute (EPRI) and the National Lab of the Rockies (formerly NREL) to support the validation of the technology.

The first pilot projects with customers are scheduled for early 2027, according to the company. These are expected to provide important insights into the technology's performance under real-world operating conditions.
