Marvel Fusion

Marvel Fusion is a German private fusion company headquartered in Munich, founded in 2020 by Moritz von Grotthuss (CEO) and Daniel Metz. The company pursues laser-driven inertial confinement fusion (ICF), an approach distinct from magnetic confinement fusion used in tokamaks and stellarators. In Marvel Fusion's concept, high-power lasers are used to rapidly compress and heat fusion fuel pellets, creating the extreme temperature and pressure conditions needed for fusion reactions.

The company's approach builds on decades of ICF research at facilities like the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory, but aims to develop a more practical and cost-effective system suitable for commercial energy production. Marvel Fusion's technical concept involves using multiple laser beams to symmetrically illuminate a fuel target, achieving the compression needed for fusion while managing the engineering challenges of repetition rate, laser efficiency, and target fabrication.

Marvel Fusion has attracted significant private investment, reflecting the surge of private capital into fusion energy in the 2020s. The company has established partnerships with Siemens Energy for power conversion and balance-of-plant systems, and with other industrial partners for laser technology and target manufacturing. The company's business model envisions building fusion power plants that could provide baseload electricity without greenhouse gas emissions or long-lived radioactive waste.

Marvel Fusion is part of a broader German fusion ecosystem that includes Proxima Fusion (stellarator), the Wendelstein 7-X stellarator at the Max Planck Institute for Plasma Physics, and various university research groups. The company represents the growing European private fusion sector, which also includes First Light Fusion (UK), General Fusion (Canada/UK), and Pulsar Fusion (UK).

The German government's support for fusion energy has grown significantly, with the 2024 German fusion strategy identifying fusion as a strategic technology and providing funding for both magnetic and inertial confinement approaches. Marvel Fusion benefits from this supportive policy environment and from Germany's strong industrial base in laser technology, precision engineering, and energy systems.
