The United Kingdom has launched an industrial joint venture with the American company TAE Technologies to locally produce neutral beams, critical components of future fusion reactors. The project receives an initial public funding of GBP5.6mn ($7.1mn) and is based on technology already supported by Alphabet, Google’s parent company, which participated in a USD150mn funding round alongside Chevron.
A transatlantic alliance at the heart of the fusion value chain
The joint venture is part of the Technology Prosperity Deal between the United Kingdom and the United States, a bilateral agreement aimed at aligning industrial efforts in advanced nuclear. TAE Technologies brings its technology developed for its field-reversed configuration reactors, while the UK Atomic Energy Authority (UKAEA) provides the Culham site infrastructure and experienced technical teams.
Neutral beams, or NBI (neutral beam injection), are heating systems essential to plasma confinement in tokamaks. They allow temperatures to exceed 100 million °C without material contact and are considered among the most complex and expensive subsystems to industrialise for fusion.
Revenue targets in healthcare and security ahead of electricity
TAE Technologies has already adapted its particle accelerators for medical applications through its subsidiary TAE Life Sciences. TAE Beam UK plans to deliver a first generation of short-pulse beams within 18 to 24 months, targeting immediate applications such as radiotherapy, food sterilisation, or security imaging, ahead of grid-connected fusion plants.
This strategy aims to generate revenue quickly while validating the technologies in regulated environments. It also allows the United Kingdom to convert expertise from the JET project into an exportable industrial base, with job creation and the structuring of a local supply chain.
An architecture designed for Western technological control
Google’s backing places the joint venture within a technology ecosystem aligned with American and British strategic priorities. The core intellectual property remains under US control, while industrialisation is located in the United Kingdom, allowing for risk distribution and tight export controls.
The components developed by TAE Beam UK are considered dual-use: applicable in both civilian fusion reactors and certain security or defence areas. This position could benefit from the regulatory accelerations outlined in new transatlantic nuclear agreements.
Expected impact for partners and the market
For TAE Technologies, the joint venture turns an internally developed capacity into a revenue-generating line independent of its own fusion projects. Google’s presence in the capital strengthens the technological visibility of the initiative and its credibility with industrial or institutional clients.
For the United Kingdom, the joint venture strengthens its post-Brexit position in advanced nuclear by establishing an export-oriented cluster in Culham focused on a high-value component. The leverage effect of public funding could also attract new investment to the region, particularly for specialised subcontractors.
