X-energy has been having a good year. Not only did Dow announce plans to invest in the company’s high-temperature gas reactor (HTGR) technology and deploy an Xe-100 reactor at a U.S. Gulf Coast facility for power and process heat by 2030, in parallel with the Xe-100 demo planned for Washington state with support from the Advanced Reactor Demonstration Program (ARDP), but X-energy’s fuel subsidiary, TRISO-X, has applied for a fuel facility license and aims to have a commercial fuel plant operating in 2025, and Canadian provinces are signaling their interest in the technology. And while news of Dow’s investment broke with well-deserved fanfare, the company’s serious interest in HTGRs—and federal support for HTGR development—goes way back.
