Engineering commercial fusion

A compact approach
to fusion energy

Kinetic Fusion is developing a compact hybrid fusion reactor to unlock the potential of fusion energy; our goal is simple: make fusion practical, scalable, and commercially viable

Commercial by designDesigned for production, scale and operation

One technology, two applications

A first product for medicine
A foundation for fusion power

The technology is being developed first for a commercial medical application, creating a pathway to revenue and technical validation before being adapted for our fusion reactor

First planned application

Medicine

A system for medical isotope production

A standalone system for medical isotope production, providing a first commercial application before full fusion power reactor development

Future reactor application

Energy

A system for fusion power

The same underlying system design will be adapted for use in a compact fusion power reactor, supporting the long-term goal of electricity generation

The physics

Small particles
A powerful reaction

Fusion combines two light atomic nuclei, releasing energy that a future power plant could turn into electricity

NeutronCarries energy

D–T

Two forms of hydrogen

Deuterium and tritium are the fuel for the proposed reactor, and their nuclei fuse to release energy

3.5 MeV

A helium nucleus

The reaction produces a helium nucleus with an energy of 3.5 MeV

14.1 MeV

A high energy neutron

The neutron carries energy that a future power plant would capture and convert into electricity

Inside the hybrid reactor

Three technologies,
One compact reactor

Inside the reactor, the fusion fuel is heated into a plasma: a gas of charged particles. Our Magnetic & Electrostatic Confinement system confines this plasma, creating the conditions required for sustained nuclear fusion

Deliver the fuel

Our standalone medical isotope production system is adapted for use in the fusion reactor

Fuel supply

Deliver and replenish nuclear fuel

Electrostatic confinement

Help form an electron cloud that creates the electric potential well

Reactor diagram with the electron cloud and potential well highlighted

Draw fuel ions inward
Sustain confinement

The electron cloud creates an electric potential well that draws positively charged fuel ions towards the centre

Confinement

Keep the fuel ions confined away from the reactor walls, helping to maintain a dense plasma

Fusion conditions

Create the conditions required for nuclear fusion

Reactor diagram with the superconducting magnets highlighted

Help hold the electron
cloud in place

High-temperature superconducting magnets generate magnetic fields that help confine the plasma

Electron confinement

Magnetic fields primarily confine the electrons, whose smaller gyroradius enables tighter confinement

Combined confinement

The combination of electrostatic and magnetic confinement helps create a dense, stable plasma core

A smaller core
A more practical path to deployment

The design aims to concentrate fusion power in a compact core, with the commercial objective of lower capital requirements and a shorter route to deployment

~60 kV

Potential Well

Electrostatic well depth, for plasma confinement, supporting a high fusion probability and reaction rate

Vessel and first wall diameter

The diameter of the reactor chamber, excluding surrounding plant and supporting systems

The development pathway

Advance towards power

Four planned stages take the underlying technology from its first commercial application to a compact fusion power system; each stage addresses a distinct technical and commercial milestone

01 / MEDICINE

04 / FUSION POWER

Scale towards
commercial power

Develop a system that produces more energy than is required to sustain the reaction, enabling practical power generation
