Cache Energy recently completed a successful demonstration of its thermochemical energy storage (TCES) at Duke Energy’s Mt. Holly testing facility, hosting several interested industrial companies. The demonstration follows a visit to Cache Energy’s facilities, where stakeholders saw firsthand the potential for rapid deployment of the company’s modular device with minimal onsite work. The demonstration marks an important milestone in advancing simple, modular, and quickly deployable heat electrification solutions. Duke Energy is one of the largest energy holding companies in the United States, serving millions of customers across multiple states. “The success of this deployment reflects how quickly meaningful progress can happen when utilities and technology providers align around speed and practicality,” said Cache Founder Arpit Dwivedi. “The industrial customers appreciated seeing the unit in operation and understanding its integration simplicity.”
Manufactured at Cache’s facility in Illinois, the TCES unit is a fully modular, shippable system designed to arrive on a standard truck and integrate with minimal onsite work. At the North Carolina test site, the device was producing heat less than a week after arriving onsite. During the demonstration, the Cache TCES system executed full charge and discharge cycles under real industrial operating conditions. The deployment confirmed reliable shipping, easy integration, consistent performance, and responsive control behavior – all achieved without major workflow disruptions. “Delighting our customers is a top priority, and this project allowed us to demonstrate new technology efficiently and at scale,” said Jonathan Landy, Director, Emerging Technology and Operations at Duke Energy. “The Cache team mobilized quickly and completed the move and installation with speed and precision.”
The project underscores the growing industrial demand for practical, rapidly deployable clean thermal solutions. “This demonstration shows that thermal storage doesn’t have to be a massive infrastructure project with huge financial and time costs,” said Dwivedi. “We can deliver, install, and be in operation in just days, not many months or years.”
