Zeno Power, a startup specializing in nuclear batteries that utilize radioactive decay to generate power, has secured $50 million in Series B funding to advance the development of their technology. These nuclear batteries are designed to operate in extreme environments where conventional batteries fail, including deep ocean, Arctic regions, space, and potentially the Moon and Mars. The funding will support scaling efforts to bring these next-generation power sources to market. Separately, The Nuclear Company has raised approximately $46 million to develop large reactor sites with some regulatory approvals, aiming to accelerate construction timelines. However, the first operational output from these reactors is not expected until the early 2030s.
