Investor brief

Avalanche proton-boron fusion via ultra-short pulses

Executive Summary

HB11 Energy, a University of New South Wales spin-out, uses non-thermal, ultra-short-pulse lasers and avalanche reactions to ignite proton-boron fusion without bulk plasma heating. The company reported avalanche p-¹¹B fusion reactions at the PALS facility in Prague in 2022 — a result that, if independently reproduced, would collapse the ignition energy requirement by orders of magnitude.

Strategic Thesis

If avalanche multiplication of p-¹¹B is real, ignition energy collapses by orders of magnitude — true table-top fusion becomes possible.

How HB11 Energy sits vs peers

Reported avalanche p-¹¹B reactions at Prague's PALS facility (2022). Pursues chain-reaction fusion without bulk thermal heating — if validated, the path collapses the entire ICF driver capex problem.

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

HB11 Energy is built entirely upon the lifetime theoretical physics of Professor Heinrich Hora, a global pioneer in laser-plasma interactions. Hora discovered that ultra-short, petawatt-intensity pulses could accelerate hydrogen nuclei directly into boron targets via non-thermal forces, entirely bypassing the need for multi-million-degree temperatures. To commercialize this elegant breakthrough, Hora teamed up with materials scientist Dr. Warren McKenzie and veteran deep-tech venture builders Jan Kirchhoff and Lukasz Gadowski, creating a powerhouse team dedicated to realizing laser-driven, completely radiation-free proton-boron fusion.

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.

Avalanche p-¹¹B Inertial Fusion

A picosecond laser pulse drives a high-energy proton beam into a boron target. If the reaction self-amplifies via secondary reactions (the avalanche), the driver energy collapses to table-top scale.

Ultra-Short Pulse Laser

Picosecond / femtosecond laser pulses on dense targets generate the energetic proton populations needed to initiate p-¹¹B.

Avalanche Multiplication

Secondary reactions amplify the initial fusion yield — the central claim under investigation.

International Facility Access

HB11 conducts experiments at the largest pulsed laser facilities worldwide.

Fuel Strategy

Category

Target efficiency

Direct — no Carnot limit

Laser-triggered avalanche p-¹¹B reaction producing only charged alpha particles, collected directly on biased grids — no neutrons, no steam, no turbine.

Conversion chain

  1. 1Petawatt laser pulse on boron target
  2. 2Non-equilibrium p-¹¹B avalanche reaction
  3. 3Three alpha particles per fusion event
  4. 4Electrostatic collection on biased grids → DC

Pure aneutronic fuel + pure direct conversion = the simplest theoretical fusion power plant: no radioactivity, no thermal cycle, no tritium handling. The unsolved question is whether the laser-avalanche ignition route can be scaled and made energy-positive.

Economic Vision

If avalanche fusion is real, the unit economics of inertial fusion collapse — turning fusion into a table-top energy source.

Vision

True table-top aneutronic fusion power.

Mission

Independently validate the avalanche claim and build the first reactor on it.

Engineering Bottlenecks

  • Independent reproduction of avalanche fusion claims
  • Driver wall-plug efficiency

The description above reflects HB11 Energy'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.
