Houston-based company ZettaJoule is set to build an innovative high-temperature gas-cooled modular reactor, the ZJ0, at the Texas A&M Engineering Experiment Station (TEES) in College Station, Texas. The reactor is designed to operate at temperatures up to 1,742°F (950°C), enabling applications such as synthetic fuels production, hydrogen generation, steelmaking, chemical processing, desalination, and data center support. The ZJ0 technology builds on decades of safe operation experience from Japan’s High Temperature Engineering Test Reactor, combining Japanese innovation with Texas’ energy leadership. The partnership between ZettaJoule and TEES, part of the Texas A&M University System, aims to advance research and workforce training in next-generation energy systems, while emphasizing safety and transparency. The addition of the ZJ0 reactor would make Texas A&M the only U.S. university with more than two nuclear research reactors on campus, enhancing its status as a premier nuclear engineering institution. This collaboration is expected
