Commonwealth Fusion Systems (CFS), the largest fusion energy company, will be the first international company to participate in UKAEA’s flagship Lithium Breeding Tritium Innovation programme (LIBRTI). LIBRTI is a £220 million UK government initiative that aims to demonstrate net tritium production – a vital capability for commercialising fusion energy that means fusion power plants can produce enough of this fuel component to cover their own use. CFS and UKAEA will work together, designing the experimental setup, developing testing protocols, and conducting experiments at the LIBRTI facility. CFS will build the test articles to be used in the first investigations.
