Our Technology

Fusion Demonstration Program

A groundbreaking fusion demonstration designed to connect energy and ecology.

The Fusion Demo Program

Explore the Fusion Demonstration Facility.

Where fusion energy happens.

With engineering work underway, the fusion demonstration has been designed to demonstrate our Magnetized Target Fusion technology, creating fusion conditions in a power-plant-relevant environment. Based in the UK with support from investors across the globe, the demonstration facility will become the world’s largest and most capable prototype for a Magnetized Target Fusion power plant – a prototype intended to demonstrate a massive step forward in practical fusion energy.

Our Impact

Propelling Fusion Forward One Milestone After Another.

With our core technologies in place, our UK facility is the next big test. Rapid progress is underway. The fusion demonstration facility will provide important insights to support our commercialization of fusion energy. By demonstrating our integrated core technologies in a power-plant-relevant fusion machine, the demonstration validates the economics of commercial fusion power and our readiness to deliver.
