First Light Fusion

Energy · Yarnton, United Kingdom · Founded 2011

Inspired by the only natural example of inertial confinement on Earth, First Light Fusion is developing a practical pathway to fusion energy using the simplest machine possible MoreLess

First Light Fusion is a groundbreaking startup that operates in the energy sector, specifically focusing on fusion power. Their unique approach, known as projectile fusion, aims to provide a simpler, more energy-efficient solution to fusion power. This technology has been proven through a world-first result, demonstrating fusion with a projectile for the first time.

The company's mission is to create the simplest machine possible to solve the problem of fusion power. They aim to develop a technology that can scale and fit with existing power plant engineering. Their unique target designs, consisting of an amplifier and a fuel capsule, are the key to their technology. The amplifier increases the pressure of the projectile impact and creates convergence, focusing shockwaves onto the fuel capsule.

To test their target designs, First Light Fusion uses two-stage gas guns. However, to achieve higher velocities, they rely on electromagnetic launch, similar to a railgun, achieved with their pulsed power machines. Their research is supported by simulation tools that allow for rapid design optimization, and they place a strong emphasis on verification and validation.

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

In terms of their business model, First Light Fusion is a research and development company. They make money by developing and potentially licensing or selling their technology to larger energy companies or governments interested in cleaner, more efficient power sources.
