RTI International cut the ribbon Thursday, September 10, on a $14 million, 25,000-square-foot expansion of its Pilot Xcelerator facility in Research Triangle Park, more than doubling the lab space the nonprofit research institute uses to help startups and established companies test cleaner fuels, energy technologies and advanced materials. The ceremony capped three years of planning, design and construction, and RTI's vice president of engineering and advanced technology, David Dausch, said the building itself came together in about 10 to 11 months.
According to WUNC News, RTI CEO Tim Gabel cut the blue ribbon at the September 10 event, marking the formal debut of a facility that Pilot Xcelerator program director Sameer Parvathikar describes as the only privately-owned industrial pilot laboratory in North Carolina. The expanded space gives RTI, an independent scientific research institute headquartered in Research Triangle Park, room to serve as a hub for commercializing technology developed by outside partners rather than relying solely on its own research pipeline. Dausch told the station that commercial partners are needed to move scientific work into the marketplace, adding that a technology needs a business case and a market entry point to succeed.
What the New Lab Actually Adds
The physical build-out is substantial. Per The Assembly NC, the 25,000-square-foot addition includes 12,000 square feet of covered process bay space with 40-foot ceilings plus 3,000 square feet of indoor control rooms and amenities, giving RTI room to host up to eight commercial projects at once. The facility runs on a modular, plug-and-play layout, with an overhead utility spine feeding compressed air, 480-volt power, hydrogen, nitrogen, carbon dioxide and cooling water to customizable equipment skids — the kind of infrastructure that lets a startup swap in new hardware without rebuilding from scratch.
Before the expansion, Pilot Xcelerator had collaborated with five companies total and currently works with two in its preexisting facility, according to WUNC News's reporting. The station reports that a few dozen companies have already voiced interest in collaborating at the new site, and that the last three participating companies came from out of state — a detail RTI leaders point to as evidence the lab can pull in business beyond North Carolina's borders while also facilitating industrial connections within the state.
Federal Grants Arrive Days Before the Ribbon-Cutting
The timing lined up with fresh federal money. The U.S. Department of Energy awarded RTI $5.5 million on September 9 for two separate technology development projects at the Pilot Xcelerator, one focused on converting natural minerals into advanced manufacturing materials and another on recycling cardboard boxes, according to PR Newswire. Those grants involve partnerships with NC State University, Gunnadoo Consulting and Thar Energy. Other projects moving through the facility include work on sustainable aviation fuel and technology that converts harmful greenhouse gases into valuable chemicals, per WUNC News's account of the grand opening.
A Pivot Born of Federal Funding Cuts
The expansion also reflects a strategic shift for the 68-year-old institute. RTI pursued the $14 million buildout partly to diversify its revenue streams after federal funding cuts led to more than 500 employee layoffs in early 2025, The Assembly NC reports, noting RTI had previously relied on the federal government for about 84% of its annual revenue. Founded in 1958 as the first anchor tenant of Research Triangle Park, RTI was created by regional university, business and government leaders to keep scientific talent in the area, and has since grown into a global institute with more than 5,000 employees, according to Business North Carolina.
Political Backing and a Bigger Neighborhood
U.S. Representative Valerie Foushee, who represents North Carolina's 4th Congressional District, attended the Research Triangle Park event and said the expansion will help position North Carolina at the forefront of national innovation projects, per WUNC News. She said the facility will transform ideas from students, researchers and academics into deployment-ready solutions. The station notes Research Triangle Park is described as the largest research park in the nation, and that as of a 2024 park report it was home to more than 385 companies and 21 million square feet of office and lab space dedicated to life sciences, information and financial technology, and agricultural initiatives.
RTI's expansion arrives as other major tenants pour money into the park. Biogen committed $2 billion to a North Carolina expansion announced in July 2025, and Novartis Gene Therapies has put $771 million toward its own buildout, according to Wake County Economic Development, which also estimates the park's 385-plus companies and 55,000 workers generate about $25.1 billion in annual economic impact across its 7,000 acres in Durham and Wake counties. In June, park tenants and landowners unanimously approved the “RTP 3.0” development framework following updated zoning that, for the first time, allows mixed-use and residential development inside the park, according to the Research Triangle Park foundation. That modernization push has coincided with a leadership change at the Research Triangle Foundation, which named a new chief exec in July to succeed retiring CEO Scott Levitan.
Entrepreneurs interested in the space can reach RTI through the Pilot Xcelerator website, WUNC News reports. With the ribbon now cut and federal grant money already flowing to two new projects, RTI's next test is whether the dozens of companies expressing interest actually sign on to fill the facility's eight available project slots.
