X-energy Plans Montgomery-Frederick County, Maryland, Operations

08/01/2025
Nuclear reactor and fuel company X-energy plans to expand its operations in Frederick County and Montgomery County, Maryland. The project is expected to create 525 jobs.

The company will relocate its headquarters to a 125,000-square-foot building in Gaithersburg and construct a new 90,000 square-foot testing facility in Frederick.

“X-energy was founded in Maryland, and we are proud to call this state our home as we enter a period of unprecedented growth,” said X-energy Chief Executive Officer J. Clay Sell. “We look forward to working with Governor Moore and his team to build on the state’s long history of nuclear innovation by making Maryland a national leader in next-generation nuclear technology.”

X-energy is a developer of advanced small modular nuclear reactors and nuclear fuel technology for clean energy generation. The company is developing a Generation IV high-temperature gas-cooled pebble-bed nuclear reactor design.

“These new facilities will play a major role in enhancing the company’s clean energy efforts, and with employees rotating between Gaithersburg and Frederick, X-energy’s impact will be felt all throughout the Capital Region,” noted Maryland Commerce Secretary Harry Coker, Jr.

“We’re proud to welcome X-energy’s latest expansion here in Frederick County. Their cutting-edge work in advanced energy technology not only strengthens our region’s innovation economy but also positions us at the forefront of clean energy solutions,” added Frederick County Division of Economic Opportunity Director Lara Fritts. “This investment underscores our county’s ?commitment to supporting companies that are solving global challenges and creating high-quality jobs for the future.”

“We are thrilled that X-energy has chosen to remain in Montgomery County,” said Montgomery County Economic Development Corporation Board Chair Elana Fine. “This is the result of a strong partnership with X-energy, built over many months of close collaboration. Together we aimed to align their growth goals with the unique assets and incentives Montgomery County offers—including the MOVE Grant and the Montgomery County Job Creation Fund. This decision reflects the shared commitment to innovation that defines our business community.”
