Fusion – the untapped energy source

Why Fusion?

Commercial fusion energy has the potential to provide the world with a clean, unlimited and secure source of power. If realised at scale, it could fundamentally transform our global energy system, eliminate energy poverty and provide vital energy security.

Impact fusion

A new approach to Inertial Fusion Energy

Impact fusion is a new approach to Inertial Fusion Energy (IFE) that is simpler, more energy efficient, and has lower physics risk. The key enabler is First Light’s unique new target technology, proven through a world-first result, showing fusion with a projectile for the first time.

Our Mission

Fusion power by the simplest means possible

First Light’s mission: Fusion power by the simplest means possible. Simplicity is a golden thread that runs through all of the company’s technology and commercial strategy.

Amplifier technology

The key technology

First Light’s unique target designs are the key technology. They have two aspects, the amplifier and the fuel capsule. The amplifier boosts the pressure of projectile impact and creates convergence, focusing shockwaves onto the fuel capsule.

Machines

Our experimental capabilities

Our drivers launch the projectile that impacts the target. We use two-stage gas guns to test target designs, but they have a velocity limit. To go faster we rely on electromagnetic launch achieved with our pulsed power machines, similar to a railgun.

Simulations

Rapid iteration

Our simulation tools underpin our research efforts, allowing rapid design optimisation. We place huge emphasis on verification and validation, comparing against an ever-increasing body of experimental data. The two main codes are supported by a large suite of additional tools.

Power plant

Commercialising fusion energy

Our power plant concept uses a liquid first wall, with pure natural lithium as the working fluid. This can be built with existing nuclear technology and avoids some of the big engineering challenges of fusion, like neutron damage and producing enough tritium.
