SwRI's $13M HEAT Facility Upgrade Revolutionizes Turbine Testing for Cleaner Energy

Southwest Research Institute (SwRI) has finished a major three-year upgrade to its High Energy Annex Test (HEAT) facility. The project cost over $13 million in 2025, funded entirely by SwRI. HEAT specialises in realistic testing of gas turbine combustors for propulsion and energy applications. The upgrade significantly boosted HEAT’s capabilities. A new high-capacity air compressor now triples the facility’s airflow and pressure capacity. Engineers also reconfigured the system to allow seamless switching between different fuels, including low-carbon and zero-carbon options.

Cost efficiency was a key focus of the renovation. Additive manufacturing cut combustor component costs by 80% compared to traditional production methods. The facility maintains continuous testing, unlike many competitors limited to intermittent runs.

HEAT validates combustion performance, safety, and design under controlled yet realistic conditions. The enhancements support the development of next-generation turbines meeting strict environmental and efficiency standards. The upgraded facility now offers greater flexibility and lower operational costs. Its improved testing capacity helps advance turbine technology for cleaner and more efficient energy solutions. The changes ensure HEAT remains at the forefront of propulsion and power research.
