SIXTY YEARS OF FUSION FUN

Fusion sector says now is time for firms to join supply chain

The Fusion22 conference in the UK was told that there is a huge potential fusion industry and businesses were urged to get involved in the supply chain now.

At a session entitled How will fusion make the transition to an industry? at the event held in the Science Museum in London, there was talk of 10,000 or more fusion power plants being required in the future.

Ross Morgan, from Tokamak Energy, said that his company, and others, were designing and aiming to build prototype plants in the 2020s, with pilot plant demonstrations in the early 2030s and using that as a platform to deploy commerical fusion within that decade.

Asked when he thought the supply chain needed to develop to support fusion, he said: "I think from our perspective it needs to start now ... we want to to engage with partners and suppliers who are going to work with us through that journey and help deliver commercial fusion power plants in the future."

Heike Freund, chief operating officer of Marvel Fusion, cited Bloomberg's asessment of the fusion industry potentially being as big as USD40 trillion and also said that in her view the two dominating topics for the next decade would be artifical intelligence in software and fusion in hardware. "We need to build this industry but I'm convinced that people will want to go into this industry, especially the younger generation - people want to work on topics that have impact, they want to work on purposeful topics" such as fusion energy tackling climate change.

She added that the development of prototype fusion plants being developed now is "an amazing opportunity for suppliers ... if you are already involved in those prototype stages you have a good chance of also being the go-to partner for the later steps to come, so I think now is really the moment in time when companies should get engaged."

Greg Willetts, vice president for Technology & Cyber Solutions within Jacobs' Energy, Security and Technology business, said his company was committed to energy transition and said, with its project management, technical solutions and engineering experience, the aim was to help make the fusion industry real.

He said that as an industry there was the "opportunity to design a new industry and make it how we want to ... a golden opportunity to make it more diverse, more inclusive, more rooted in social value into the community, we can design that in by the way thiongs are procured".

The aim of the conference was to bring together the whole fusion sector to demonstrate the sector’s potential, and was organisated by the UK Atomic Energy Agency's Fusion Cluster and came alongside a number of announcements, including Canada’s General Fusion and the UKAEA agreeing to collaborate on projects to "advance the commercialisation of magnetised target fusion energy", including 'honing' General Fusion’s demonstration machine being built at Culham, near Oxford.

Earlier this month the UKAEA announced that its newly completed GBP10 million (USD11.4 million) extension has doubled the size of its Materials Research Facility (MRF) at Culham. Specialist materials that can withstand extreme conditions are a critical part of delivering fusion energy as a safe, sustainable, low-carbon energy supply, the UKAEA said. They are also essential in the development of STEP (Spherical Tokamak for Energy Production), the UK's prototype fusion power plant. The investment has seen an additional 12 shielded research rooms, used to hold high-end analytical instrumentation, added to the facility, as well as extensive new active chemical laboratory space, for scientists and engineers to develop more neutron-tolerant materials.

The UK also recently announced the selection of a site at West Burton in Nottinghamshire to host the STEP demonstration plant, which is due to begin operating by 2040. And last week the UKAEA and Tokamak Energy signed a five-year framework agreement for closer collaboration "on developing spherical tokamaks as a route to commercial fusion energy".

General Fusion and UKAEA outline further fusion collaboration

The projects will help "hone" the design of General Fusion’s demonstration machine being built at the UK’s "fusion cluster" at Culham, near Oxford.

Greg Twinney, CEO of General Fusion, said: "The leading-edge fusion researchers at UKAEA have proven experience building, commissioning, and successfully operating large fusion machines. Partnering with UKAEA’s incredible team will fast-track work to advance our technology and achieve our mission of delivering affordable commercial fusion power to the world."

Ian Chapman, CEO of UKAEA, said: "Fusion energy is one of the greatest scientific and engineering quests of our time. This collaboration will enable General Fusion to benefit from the ground-breaking research being done in the UK and supports our shared aims of making fusion part of the world’s future energy mix for generations to come."

Since its founding in 2002, General Fusion has formed more than 200,000 hydrogen plasmas. In its collaboration with the UKAEA the company will "harness UKAEA’s extensive neutron modelling software and expertise to simulate the neutron flux distribution from General Fusion’s operational large-scale plasma injector as well as future machines".

General Fusion is based in Vancouver, Canada, with locations in Oak Ridge, Tennessee in the USA and in London in the UK. In announcing the collaboration it said it benefits from the UKAEA’s expertise in building polychromators, used to measure 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," it added.

The UKAEA carries out fusion energy research on behalf of the UK government, overseeing the country’s fusion programme, including the MAST Upgrade (Mega Amp Spherical Tokamak) experiment as well as hosting the JET - Joint European Tourus - at Culham, which is operated for scientists from around Europe.

General Fusion's Magnetised Target Fusion approach involves injecting hydrogen plasma into a liquid metal sphere, where it is compressed and heated so that fusion occurs. The heat from the fusion of the hydrogen atoms is transferred into the liquid metal. This is different to the tokamak approach, which is used in JET and MAST Upgrade, but General Fusion and UKAEA said, when they announced last year that General Fusion was going to build its demonstration plant at Culham, that they intend to collaborate on a range of fusion energy technologies for power plant design and operation.

General Fusion says its approach to fusion "maximises the reapplication of existing industrialised technologies, bypassing the need for expensive superconducting magnets, significant new materials, or high-power lasers".

The announcement coincided with the first day of Fusion22, a conference for the industry organised by the UKAEA in London, which is focusing on the steps needed to develop a fusion industry, with the UK seeking to build on its established fusion research and resources and help make fusion energy a reality within the next few years.

Earlier this month the UKAEA announced that its newly completed GBP10 million (USD11.4 million) extension has doubled the size of its Materials Research Facility (MRF) at Culham. Specialist materials that can withstand extreme conditions are a critical part of delivering fusion energy as a safe, sustainable, low carbon energy supply, the UKAEA said.
