General Fusion and UK Atomic Energy Authority (UKAEA) announce collaborative agreement to advance commercial fusion energy

General Fusion and the UK Atomic Energy Authority (UKAEA) kicked off projects to advance the commercialization of magnetized target fusion energy as part of a collaborative agreement. The results will hone the design of General Fusion’s demonstration machine being built at the Culham Campus, part of the UK fusion cluster. Ultimately, the company expects the projects will support its efforts to provide low-cost and low-carbon energy to the electricity grid.

General Fusion’s approach to fusion maximizes the reapplication of existing industrialized technologies, bypassing the need for expensive superconducting magnets, significant new materials, or high-power lasers. The demonstration machine is to designed to demonstrate General Fusion’s Magnetized Target Fusion technology, creating fusion conditions in a power-plant-relevant environment.

General Fusion benefits from the UKAEA’s expertise in building polychromators, which are used in an industry-standard diagnostic called Thomson Scattering that measures electron temperature. The UKAEA will be building a new, larger Thomson Scattering system, which will be installed on General Fusion’s fusion demonstration machine at Culham. Electron temperature measurements are used for thermal confinement calculations, a fundamental calculation to determine experiment success.

Since its founding, General Fusion has formed more than 200,000 hydrogen plasmas, averaging 100 neutron-generating plasmas per day. In its collaboration with the UKAEA, the company will harness UKAEA’s extensive neutron modeling software and expertise to simulate the neutron flux distribution from General Fusion’s operational large-scale plasma injector (PI3) as well as future machines. The simulation results from PI3 will be used to develop higher level physics models that will inform the design of neutron diagnostics on future machines, including the fusion demonstration and commercial power plants.

In the past 20 years, enabling technologies, such as advanced composite materials and additive manufacturing, have offered innovative new pathways to resolve historical barriers to fusion energy. In General Fusion’s fusion demonstration, the design will use special steel that can withstand the high temperatures and compressive forces found in a fusion vessel. The UKAEA will use its vacuum facilities to test the specific steel that General Fusion will use and help inform the demonstration facility’s final design.

General Fusion is based in Vancouver, Canada, with locations in London, UK, and Oak Ridge, Tennessee, USA. The company was established in 2002 and is funded by a global syndicate of leading energy venture capital firms, industry leaders, and technology pioneers.



There is no overwhelming evidence we are anywhere near long-period, sustained, positive-energy, low-cost (comparatively), upscalable, grid-scale power output on a fusion source.
Though, I suppose the vast number of demonstration projects must somehow be finding financing and staff. Best to them.


Interesting. Hope it works but I am not holding my breath.

more than 200,000 hydrogen plasmas, averaging 100 neutron-generating plasmas per day.
... is pathetic.

Jer, you are right.  This is NOTHING close to an energy-positive system, let alone something that willl save us.


Mr Fusion is just a few decades away! Lots of uses are waiting!
Super low cost batteries, solar, wind... will make anything with LCOE more than a few cents per kW-hr noncompetitive except for very limited niche markets.
