The £220m UK Tritium Blanket Programme has taken a major leap forward with Commonwealth Fusion Systems (CFS) becoming the first overseas company to join its flagship Lithium Breeding Tritium Innovation programme. This international partnership marks a crucial step in accelerating the development of technologies essential for commercialising fusion energy.
LIBRTI, funded by the UK government, aims to demonstrate 'net tritium production' – a vital capability for making fusion a viable energy source. The £220m initiative is establishing a new technology facility at UKAEA's Culham Campus, incorporating a high-flux neutron source, which will provide industry partners with infrastructure to develop and test blanket technologies in simulated full-scale fusion conditions.
Commonwealth Fusion Systems, the most well-funded fusion energy company globally, having raised over US$3 billion in private capital, is actively constructing its SPARC demonstration machine. Their participation in LIBRTI involves joint efforts with UKAEA in designing experimental setups and conducting experiments. CFS will also be responsible for constructing test articles to be used in initial investigations.
UKAEA's CEO, Tim Bestwick, highlighted the importance of global partnerships in fusion research, while Amanda Quadling, Senior Responsible Officer for LIBRTI, described CFS's involvement as a 'defining moment' for the programme. Brandon Sorbom, Co-founder and Chief Science Officer at CFS, underscored the significance of LIBRTI's specialised testing capabilities.
The partnership follows momentum from the King’s Address to the U.S. Congress in April, which highlighted growing international collaboration in fusion energy. UKAEA's collaboration with CFS will add momentum to their efforts, accelerating the global pathway towards demonstrated fusion power plant scale technology.
