Focused Energy GmbH is a German-American fusion technology company founded in 2021 as a spin-off from the Technical University of Darmstadt. Headquartered in Darmstadt, Germany, with offices in Berlin and several U.S. locations including the San Francisco Bay Area, it develops laser-based inertial confinement fusion systems for potential commercial energy applications.
In May 2026, the company completed a $240 million Series A financing round, the largest secured Series A in the global fusion sector to date, with RWE increasing its investment by an additional €60 million. Focused Energy is advancing laser fusion development at the former Biblis nuclear site in Hesse, Germany, and is participating in a federal tender for a national laser fusion hub.
Also known as Focused Energy Inc..
Additional €60m follows an October 2025 stake; proceeds will develop laser-fusion work at Biblis and support Germany's bid for a national laser fusion hub.
