Durion Information

Onsite thermal energy storage for industrial process heat. Durion helps manufacturers and processors take control of what their heat costs. Our HeatTrap system stores energy as pressurized hot water at up to 300°C and supplies steam, hot water and power around the clock, for 15 or more hours per charge. HeatTrap can charge two ways: The electric configuration uses an electric boiler or heat pump during off-peak, overnight and surplus-renewable hours. The solar-charged configuration uses concentrating solar collectors, where land and sun allow. Systems are modular, from 5 to 100+ MWh thermal, and built from API 5L pipeline sections, the same supply chain the oil and gas industry uses. That keeps materials simple and costs predictable. No lithium, no cobalt. Customers can buy energy, not equipment. Under a long-term heat and power purchase agreement, you pay for the energy delivered, with no capital outlay, and get a heat cost you can plan around. Who we work with Food and beverage processors, chemical manufacturers, and other plants running 24/7 or multiple shifts, with 500 kW or more of thermal demand. Sites burning propane, fuel oil or gas for process heat tend to see the strongest economics. Proof points A complete system, parabolic trough, HeatTrap storage and an ORC engine, was built and operated together at the UL-Lafayette START facility in Crowley, Louisiana, with support from DOE and NSF. DOE SBIR Phase I and Phase II complete, and a DOE SOLAR Tier 2 demonstration underway with Green Mountain Power. Six issued U.S. patents on the HeatTrap design. Our team has developed more than $250M in renewable energy projects through prior work at Norwich Technologies and Northern Power. Durion is based in Vermont and works with plants across the United States. If you run a boiler and want a clearer view of what your heat could cost, we’d be glad to talk.
