Investor brief
Short-pulse laser fusion on nanostructured aneutronic targets
Executive Summary
Marvel Fusion is Europe's leader in short-pulse laser-driven proton-boron inertial fusion. The company is partnering with Colorado State University on a $150M+ laser facility to test nanostructured aneutronic targets at fusion-relevant fluence.
Strategic Thesis
Aneutronic p-¹¹B with picosecond pulses on nanostructured targets bypasses the central-hot-spot ignition problem.

How Marvel Fusion sits vs peers
Short-pulse nanostructured-target approach targeting p-¹¹B. Constructing a $150M+ Colorado State University facility — the largest dedicated aneutronic test platform globally.
Class engineering bottlenecks
- Driver wall-plug efficiency: NIF-class flashlamp lasers sit at < 1%; diode-pumped solid-state and GaN blue diodes target 10–20%.
- Target manufacturing throughput: every shot consumes one precision-machined target — economics demand mass production at ¢-class unit cost.
- p-¹¹B Coulomb barrier requires T ≳ 150–200 keV and triple products of 10²⁴–10²⁵ keV·s·m⁻³.
- Rep-rate scaling: NIF fires once per ~6 hours; commercial plants need 10 Hz sustained for years.
LCOE drivers
- Driver capex dominates — diode-pumped solid-state and GaN blue-diode roadmaps target order-of-magnitude wall-plug efficiency gains.
- Target consumable cost per shot scales linearly with energy delivered — manufacturing automation is existential.
- Aneutronic p-¹¹B pivot eliminates the neutron-handling and tritium-breeding capex of D-T ICF.

Founding Team
Marvel Fusion represents a powerhouse alliance between world-class European laser scientists, quantum theorists, and heavy-tech venture capitalists. While Moritz von der Linden and Pasha Shabalin drive the company's aggressive financial and operational scale, Dr. Georg Korn brings legendary authority from the European Extreme Light Infrastructure (ELI) project. Alongside mathematical physicist Dr. Karl-Georg Schlesinger, this team is commercializing ultra-short, ultra-intense laser systems. Their proprietary technology interacts with nanostructured targets to trigger non-thermal, high-efficiency proton-boron fusion, establishing a dominant alternative pathway within the European energy sector.

The Problem
Global electricity demand is entering an unprecedented growth phase driven by AI infrastructure, data centers, transport electrification, industrial decarbonization, water desalination, and advanced manufacturing. Solar suffers intermittency, wind capacity-factor variability, natural gas carbon emissions, conventional nuclear cost and deployment speed, and batteries energy-density and duration limits. The world requires a new source of clean, dispatchable baseload energy. Fusion represents the ultimate energy source — the challenge is making it commercially practical.
Picosecond-Pulse p-¹¹B Inertial Fusion
Marvel uses picosecond-class laser pulses on precision-nanostructured p-¹¹B targets to bypass the central-hot-spot ignition problem that has dominated traditional inertial fusion.
Picosecond Laser Driver
Short-pulse laser architecture optimised for nonthermal energy coupling into nanostructured targets.
Nanostructured Targets
Engineered nanostructures enhance laser absorption and produce the energetic ion populations needed to initiate p-¹¹B reactions.
Colorado Laser Facility
Joint $150M+ facility at Colorado State University; ground broken in 2025.
Fuel Strategy
Hydrogen-Boron (p-¹¹B)
Aneutronic operation eliminates first-wall damage and enables direct energy capture.
Product Platform
Marvel/CSU Laser Facility
Major short-pulse laser facility under construction in Colorado.
Energy Conversion
Thermal (Rankine/Brayton)
Aneutronic
~35–40% electrical
Ultra-short-pulse laser ignition of p-¹¹B fuel pellets at high repetition rate; alpha-particle energy deposited in a wall and recovered as heat for a conventional steam cycle.
Conversion chain
- 1Femtosecond laser pulse on nanostructured p-¹¹B pellet
- 2Aneutronic fusion → alpha particles
- 3Alphas thermalize in first-wall blanket
- 4Steam Rankine cycle → turbine → grid
Keeps the back end conventional (proven steam turbines) while still benefiting from aneutronic fuel: vastly simpler shielding, no tritium breeding, longer materials life.
Economic Vision
Eliminating the breeding blanket and most of the shielding via aneutronic operation collapses balance-of-plant cost; the remaining engineering problem is driver efficiency.
Vision
Bring aneutronic inertial fusion from the lab to the grid.
Mission
Prove p-¹¹B ignition with short-pulse lasers on nanostructured targets.
Engineering Bottlenecks
- Picosecond laser energy at fusion-relevant fluence
- Nanostructured target mass production

The description above reflects Marvel Fusion's publicly stated technology goals, roadmap and architecture. Many elements — particularly net-energy gain at scale, advanced fuel cycles, and grid-relevant economics — remain ambitious objectives that have not yet been demonstrated commercially anywhere in the fusion industry. Forward-looking statements should be treated as engineering targets, not certainties.
