X-energy specializes in high-temperature gas-cooled reactors (HTGRs) using its Xe-100 design — an 80 MWe unit scalable to a four-pack 320 MWe plant. Amazon made a $700 million investment in X-energy in 2025. The company is advancing its first plant at Dow Chemical's Texas site under the DOE Advanced Reactor Demonstration Program. X-energy Canada is also pursuing licensing.
