Darmstadt-based Focused Energy has secured $240m in a record-breaking Series A financing round. This marks the largest fully secured Series A funding in the global fusion industry to date, positioning the company as the most valuable fusion firm in Europe.
The capital will support development of a fusion project at a decommissioned German NPP site owned by utility RWE in Biblis, Hesse. Focused Energy aims to accelerate fusion system development and establish Biblis as a blueprint for industrial laser fusion. The project leverages existing nuclear-grade infrastructure, regulatory precedents, and grid connections to cut development timelines and costs. Construction goals target delivering the first commercial laser fusion power plant output by the mid-2030s.
RWE anchored the oversubscribed round, expanding its commitment with a $60m injection. Key participants include Germany’s Federal Agency for Breakthrough Innovation (SPRIND – Bundesagentur für Sprunginnovationen Deutschland), the European Innovation Council Fund, and returning lead investor Prime Movers Lab. The state of Hesse additionally provided an €18.4m ($21.4m) infrastructure grant via Economic Minister Kaweh Mansoori.
Focused Energy employs a direct-drive laser fusion approach based on inertial confinement. High-performance lasers compress and ignite mass-produced capsules containing Deuterium-Tritium fuel. This method mimics the breakthrough inertial confinement physics validated by the US National Ignition Facility (NIF) – currently the only fusion approach to demonstrate a verified net energy gain.
“Thanks to its excellent research ecosystem and innovative start-ups such as Focused Energy – one of the leading companies in the field of laser fusion – Germany is well-positioned to take a leading global role in nuclear fusion.” Said RWE CEO Dr Markus Krebber. “That is why we are prepared to further expand our investment in Focused Energy. It sends an important message that the German federal and state governments are working together to advance development with the goal of building a commercial fusion reactor in Germany. RWE fully supports this goal: with our sites that we are currently decommissioning, their existing nuclear infrastructure, and our long-standing expertise in dealing with regulatory approvals, we are creating ideal conditions to secure internationally competitive advantages for Germany, both in terms of time and costs.”
Focused Energy co-founder and CEO Thomas Forner noted: “Fusion energy is entering a new era in Germany and Europe. It is now about translating our scientific excellence and industrial strength in fusion technology into industrial value creation,” explains, of. “The successful financing round confirms our scientifically grounded laser fusion approach, which has taken Focused Energy from a startup to the world’s leading laser fusion company in just four years. With the new capital, we can further expand our lead in laser fusion in Hesse.”
Focused Energy is a German-American deep-tech company spun off in July 2021 from the Technical University of Darmstadt. It operates as a bridge between European scientific research and American venture-backed scaling. It is headquartered in Darmstadt, Germany, with key US offices in Redwood City, California (San Francisco Bay Area) and Austin, Texas. The company includes more than 160 leading scientists and engineers from more than 20 countries.
The company’s foundation was catalysed by the historic August 2021 “NIF Shot” at the US Lawrence Livermore National Laboratory (LLNL), which proved laser fusion physics viable. Co-founders Dr Todd Ditmire and Professor Markus Roth spent 30 years helping design those systems. Following the ignition breakthrough, Focused Energy strategically hired top minds directly from LLNL. This includes target design expert Debra Callahan and former LLNL Chief Scientist Prav Patel.
Focused Energy’s technology is based on Proton Fast Ignition. Conventional laser fusion uses one massive laser array to compress and heat fuel simultaneously. Focused Energy uses one set of lasers to tightly compress a mass-produced “Pearl” capsule of Deuterium-Tritium fuel. A secondary ultra-fast, high-power laser beam then delivers a sudden pulse of protons to “spark” the ignition. This fast-ignition method drastically lowers the total laser energy required to trigger fusion, increasing the net energy gain and dramatically lowering plant construction costs.
Unlike deep-tech companies that remain pre-revenue for decades, Focused Energy commercialises its near-term tech. They generate early-stage revenue via Laser-Driven Radiation Sources (LDRS). These high-intensity, laser-produced proton and x-ray bursts are sold to industries for non-destructive infrastructure testing and advanced medical imaging.
