Composites Manufacturing Education and Technology Facility

NREL's Composites Manufacturing Education and Technology (CoMET) Facility supports wind energy, water power, and composite industries in advancing materials and manufacturing research.

CoMET opened its doors in 2017. The cutting-edge facility is the result of a funding partnership between the U.S. Department of Energy's Advanced Manufacturing and Industrial Decarbonization Offices, the Institute for Advanced Composites Manufacturing Innovation, the State of Colorado, and NREL.

Designed to work in conjunction with NREL's design, analysis, and structural validation capabilities, the facility expedites composites materials and manufacturing innovation and is open to industry partners, university researchers, and everyone in between.

In October 2020, the Advanced Thermoplastic Resins for Manufacturing Wind Turbine Blades project, a technology born out of CoMET, was honored with an R&D 100 Special Recognition Award for being a "market disruptor." Watch the video to learn more about this game-changing wind and water power innovation and how CoMET's capabilities enabled its development.

Visit or Take a Virtual Tour

Situated on the sprawling 305-acre Flatirons Campus, the 10,000-ft2 CoMET expands NREL's composite manufacturing research capabilities by enabling researchers to design, prototype, validate, and manufacture composite wind and marine turbine blades and other components in one location.

The campus, which hosts the National Wind Technology Center, is about 5 miles south of Boulder, Colorado (25 miles north of NREL's Golden-based campus). The cities of Louisville and Broomfield are nearby. The Flatirons Campus is approximately 37 miles northwest of Denver International Airport.

Cutting-Edge Capabilities

The CoMET facility grants users access to 3D-printed blade tooling, composite material mixing equipment, state-of-the-art manufacturing techniques, and novel materials for rapid prototyping. Users can also simulate and model designs and manufacturing methods and characterize the structural properties of their prototypes.
