About Gen4 Energy

Gen4 Energy was a privately held corporation that aimed to commercialize small, modular nuclear reactors. The company, formerly known as Hyperion Power Generation, was focused on the design, construction, and sale of 25 MWe nuclear reactors. These reactors were intended to be modular, relatively inexpensive, and inherently safe.

The primary market for these reactors included applications such as heat generation, electricity production, and desalination. Gen4 Energy held the commercialization rights to introduce, license, manufacture, market, and distribute its Gen4 Module reactor through a technology transfer program.
