Gen4 Energy, Inc. (formerly Hyperion Power Generation, Inc.) was a privately held corporation formed to construct and sell several designs of relatively small (70 MW thermal, 25 MW electric) nuclear reactors, which they claimed would be modular, inexpensive, inherently safe, and proliferation-resistant. According to news coverage, these reactors could be used for heat generation, production of electricity, and other purposes, including desalination.
The company went out of business on the 1st of April 2018, after losing out on a second round of grants from the Department of Energy in January 2016.
