General Fusion: update to October 10, 2023

It seems that Canadian nuclear energy company General Fusion has finally moved from Burnaby to Richmond (both are part of the Metro Vancouver Region). The move first announced in 2021 (see my November 3, 2021 posting for the news and a description of fusion energy; Note: fission is a different form of nuclear energy, fusion is considered clean/green).

I found confirmation of the move in an August 9, 2023 article by Kenneth Chan for the dailyhive.com

If all goes as planned, a major hurdle in fusion-based, zero-emission clean energy innovation could be produced on Sea Island in Richmond in just three years from now.

BC-based General Fusion announced today it has plans to build a new magnetized target fusion (MTF) machine at the company’s global headquarters at 6020-6082 Russ Baker Way [emphasis mine] near the South Terminal of Vancouver International Airport (YVR). [Note: YVR is located in Richmond, BC]

Chan goes on to note (from his August 9, 2023 article), Note: A link has been removed,

This machine will be designed to achieve fusion conditions of over 100,000,000°C by 2025, with “scientific breakeven” conditions by 2026. This will “fast-track” the company’s technical progress.

More specifically, this further proof-of-concept will show General Fusion’s ability to “symmetrically compress magnetized plasmas in a repeatable manner and achieve fusion conditions at scale.”

General Fusion’s technology is designed to be lower cost by avoiding other approaches that require expensive superconducting magnets or high-powered lasers.

The YVR machine is intended to support further work and investment and reduce the risk of General Fusion’s commercial-scale demonstration test plan in Culham Campus of the United Kingdom Atomic Energy Authority (UKAEA) — located just outside of Oxford, west of London. The UK plant has effectively been delayed, [emphasis mine] with the goal now to provide electricity to the grid with commercial fusion energy by the early to mid-2030s.

“Our updated three-year Fusion Demonstration Program puts us on the best path forward to commercialize our technology by the 2030s,” said Greg Twinney, CEO of General Fusion, in a statement. “We’re harnessing our team’s existing strengths right here in Canada and delivering high-value, industry-leading technical milestones in the near term.”

Canada, always a colony

I wonder what happened to the UKAEA deal. In my October 28, 2022 posting (Overview of fusion energy scene) General Fusion was downright effusive in its enthusiasm about the joint path to commercialization with a demonstration machine to be built in the UK. Scroll down to my ‘Fusion energy explanation (2)’ subhead for more details.

It now looks as if the first demonstration will be build and tested in Canada, from an August 9, 2023 General Fusion news release,

General Fusion announced a new Magnetized Target Fusion (MTF) machine that will fast-track the company’s technical progress. To be built at the company’s new Richmond headquarters, this ground-breaking machine is designed to achieve fusion conditions of over 100 million degrees Celsius by 2025, [emphasis mine] and progress toward scientific breakeven by 2026. In addition, the company completed the first close of its Series F raise for a combined $25 million USD (approximately $33.5 million CAD) of funding. The round was anchored by existing investors, BDC Capital and GIC. It also included new grant funding from the Government of British Columbia, which builds upon the Canadian government’s ongoing support through the Strategic Innovation Fund (SIF). 

This machine represents a significant new pillar to accelerate and de-risk [emphasis mine] General Fusion’s Demonstration Program, designed to leverage the company’s recent technological advancements and provide electricity to the grid with commercial fusion energy by the early to mid-2030s.  

Over the next two to three years, General Fusion will work closely with the UK Atomic Energy Authority [UKAEA] to validate the data gathered from [Lawson Machine 26] LM26 and incorporate it into the design of the company’s planned commercial scale demonstration in the UK.

So, the machine is being ‘de-risked’ in Canada first, eh?

September 2023

There was an interesting UK addition to General Fusion’s board of directors according to a September 6, 2023 news release,

Today [September 6, 2023], General Fusion announced the appointment of Norman Harrison to its Board of Directors. Norman is a world-class executive in the energy sector, with 40 years of unique experience providing leadership to both the fusion energy and nuclear fission communities.

His experience includes serving as the CEO of the UK Atomic Energy Authority (UKAEA) from 2006 to 2010 [emphasis mine], when he oversaw the groundbreaking research being conducted by the Joint European Torus (JET), the world’s largest fusion experiment and the only one operating using deuterium-tritium fuel, as it pushed the frontiers of fusion science. Norman’s expertise will support General Fusion as the company completes its Magnetized Target Fusion (MTF) demonstration, LM26 [scroll up to August 9, 2023 news release in the above for details] , at its Canadian headquarters. LM26 is targeting fusion conditions of 100 million degrees Celsius by 2025 and is charting a path to scientific breakeven equivalent by 2026. The results achieved by LM26 will be validated by the UKAEA and incorporated into the design of the company’s near-commercial machine, which is planned to be built at the UKAEA’s Culham Campus. 

Norman’s background also includes leading the construction and operations of large-scale power plants. As a result, his guidance will benefit General Fusion as it progresses to commercializing its MTF technology by the early to mid-2030s.

“I’ve been a part of the fusion energy industry for many years now. General Fusion’s unique technology stands out and has exciting promise to put fusion energy onto the electricity grid,” said Norman Harrison. “I am thrilled to join the General Fusion team and be a part of the company’s progress.”

“Norman’s wealth of expertise in advancing fusion technology and operating large electricity infrastructure provides us with meaningful insight into what is required to effectively bring Magnetized Target Fusion to the energy grid in a cost-effective, practical way,” said Greg Twinney, CEO, General Fusion. “We look forward to working with him as General Fusion transforms the commercial power industry with reliable fusion power.”

About General Fusion

General Fusion is pursuing a fast and practical approach to commercial fusion energy and is headquartered in Richmond, B.C. The company was established in 2002 and is funded by a global syndicate of leading energy venture capital firms, industry leaders and technology pioneers. …

So, after postponing plans to build a build a demonstration plant with UKAEA and deciding to build it in Canada where it can be ‘de-risked’ here first, General Fusion adds a former UKAEA CEO to their company board. This seems a little strategic to me.

October 2023

Here’s the latest from an October 10, 2023 news release,

Today [October 11, 2023], General Fusion and Kyoto Fusioneering announced a Memorandum of Understanding (MOU) to accelerate the commercialization of General Fusion’s proprietary Magnetized Target Fusion (MTF) technology, aiming for grid integration in the early to mid-2030s. The companies will collaborate to advance critical systems for MTF commercialization, including the tritium fuel cycle, liquid metal balance of plant, and power conversion cycle.

Tritium, a hydrogen isotope and key fusion fuel, does not occur naturally and must be produced or “bred” in the fusion process. General Fusion’s game-changing commercial power plant design features a proprietary liquid metal wall that compresses plasma to fusion conditions, protects the fusion machine’s vessel components, and breeds tritium upon interacting with the fusion products. This design allows the machine to be self-sustaining, generating fuel for the life of the power plant while facilitating efficient energy extraction from the fusion reaction through a liquid metal loop to a heat exchanger.

Kyoto Fusioneering specializes in fusion power plant systems that complement the plasma confinement core, are applicable to various fusion confinement concepts, such as MTF, and are on the critical path for fusion commercialization. The complementary capabilities of both organizations will enable parallel development of key systems supporting MTF commercialization. Initial collaboration under this MOU will focus on liquid metal experimentation and fuel cycle system development at both the General Fusion and Kyoto Fusioneering facilities, such as establishment of balance of plant and power conversion test facilities, liquid metal loops, and vacuum systems.

Quotes:

“Currently, our new machine, LM26, is on-track to achieve fusion conditions by 2025, and progress towards scientific breakeven by 2026,” said Greg Twinney, CEO, General Fusion. “Harnessing the unique technological and engineering expertise of Kyoto Fusioneering will be instrumental as we translate LM26’s groundbreaking results into the world’s first Magnetized Target Fusion power plant.”

“We’re thrilled to join forces with General Fusion. Our combined expertise will accelerate the path to commercial fusion energy, a critical step toward a sustainable, decarbonized future,” said Satoshi Konishi, Co-founder and Chief Fusioneer, Kyoto Fusioneering.

Quick Facts:

Magnetized Target Fusion [prepare yourself for 1 min. 21 secs. of an enthusiastic Michel Laberge, company founder and chief science officer] uniquely sidesteps challenges to commercialization that other technologies face. The proprietary liquid metal liner in the commercial fusion machine is mechanically compressed by high-powered pistons. This enables fusion conditions to be created in short pulses rather than creating a sustained reaction. General Fusion’s design does not require large superconducting magnets or an expensive array of lasers.

General Fusion’s design will use deuterium-tritium fuel for its commercial power plant. Both are isotopes of hydrogen. Deuterium occurs naturally and can be derived from seawater. Tritium needs to be produced, which is why General Fusion’s unique and proprietary technology that breeds tritium as a byproduct of the fusion reaction is a game-changer.

Kyoto Fusioneering was spun out of Kyoto University. It is home to world-class R&D facilities, and its team has a combined total of approximately 800 years of experience [emphasis mine].

About Kyoto Fusioneering

Kyoto Fusioneering, established in 2019 [emphasis mine], is a privately funded technology startup with facilities in Tokyo and Kyoto (Japan), Reading (UK), and Seattle (USA). The company specialises in developing advanced technologies for commercial fusion power plants, such as gyrotron systems, tritium fuel cycle technologies, and breeding blankets for tritium production and power generation. Working collaboratively with public and private fusion developers around the world, Kyoto Fusioneering’s mission is to make fusion energy the ultimate sustainable solution for humanity’s energy needs.

800 years of experience seems to be a bit of a stretch for a company established four years ago with 96 employees as of July 1, 2023 (see Kyoto Fusioneering’s Company Profile webpage) but hat’s off for the sheer gutsiness of it.

Limitless energy and the International Thermonuclear Experimental Reactor (ITER)

Over 30 years in the dreaming, the International Thermonuclear Experimental Reactor (ITER) is now said to be 1/2 way to completing construction. A December 6, 2017 ITER press release (received via email) makes the joyful announcement,

WORLD’S MOST COMPLEX MACHINE IS 50 PERCENT COMPLETED
ITER is proving that fusion is the future source of clean, abundant, safe and economic energy_

The International Thermonuclear Experimental Reactor (ITER), a project to prove that fusion power can be produced on a commercial scale and is sustainable, is now 50 percent built to initial operation. Fusion is the same energy source from the Sun that gives the Earth its light and warmth.

ITER will use hydrogen fusion, controlled by superconducting magnets, to produce massive heat energy. In the commercial machines that will follow, this heat will drive turbines to produce electricity with these positive benefits:

* Fusion energy is carbon-free and environmentally sustainable, yet much more powerful than fossil fuels. A pineapple-sized amount of hydrogen offers as much fusion energy as 10,000 tons of coal.

* ITER uses two forms of hydrogen fuel: deuterium, which is easily extracted from seawater; and tritium, which is bred from lithium inside the fusion reactor. The supply of fusion fuel for industry and megacities is abundant, enough for millions of years.

* When the fusion reaction is disrupted, the reactor simply shuts down-safely and without external assistance. Tiny amounts of fuel are used, about 2-3 grams at a time; so there is no physical possibility of a meltdown accident.

* Building and operating a fusion power plant is targeted to be comparable to the cost of a fossil fuel or nuclear fission plant. But unlike today’s nuclear plants, a fusion plant will not have the costs of high-level radioactive waste disposal. And unlike fossil fuel plants,
fusion will not have the environmental cost of releasing CO2 and other pollutants.

ITER is the most complex science project in human history. The hydrogen plasma will be heated to 150 million degrees Celsius, ten times hotter than the core of the Sun, to enable the fusion reaction. The process happens in a donut-shaped reactor, called a tokamak(*), which is surrounded by giant magnets that confine and circulate the superheated, ionized plasma, away from the metal walls. The superconducting magnets must be cooled to minus 269°C, as cold as interstellar space.

The ITER facility is being built in Southern France by a scientific partnership of 35 countries. ITER’s specialized components, roughly 10 million parts in total, are being manufactured in industrial facilities all over the world. They are subsequently shipped to the ITER worksite, where they must be assembled, piece-by-piece, into the final machine.

Each of the seven ITER members-the European Union, China, India, Japan, Korea, Russia, and the United States-is fabricating a significant portion of the machine. This adds to ITER’s complexity.

In a message dispatched on December 1 [2017] to top-level officials in ITER member governments, the ITER project reported that it had completed 50 percent of the “total construction work scope through First Plasma” (**). First Plasma, scheduled for December 2025, will be the first stage of operation for ITER as a functional machine.

“The stakes are very high for ITER,” writes Bernard Bigot, Ph.D., Director-General of ITER. “When we prove that fusion is a viable energy source, it will eventually replace burning fossil fuels, which are non-renewable and non-sustainable. Fusion will be complementary with wind, solar, and other renewable energies.

“ITER’s success has demanded extraordinary project management, systems engineering, and almost perfect integration of our work.

“Our design has taken advantage of the best expertise of every member’s scientific and industrial base. No country could do this alone. We are all learning from each other, for the world’s mutual benefit.”

The ITER 50 percent milestone is getting significant attention.

“We are fortunate that ITER and fusion has had the support of world leaders, historically and currently,” says Director-General Bigot. “The concept of the ITER project was conceived at the 1985 Geneva Summit between Ronald Reagan and Mikhail Gorbachev. When the ITER Agreement was signed in 2006, it was strongly supported by leaders such as French President Jacques Chirac, U.S. President George W. Bush, and Indian Prime Minister Manmohan Singh.

“More recently, President Macron and U.S. President Donald Trump exchanged letters about ITER after their meeting this past July. One month earlier, President Xi Jinping of China hosted Russian President Vladimir Putin and other world leaders in a showcase featuring ITER and fusion power at the World EXPO in Astana, Kazakhstan.

“We know that other leaders have been similarly involved behind the scenes. It is clear that each ITER member understands the value and importance of this project.”

Why use this complex manufacturing arrangement?

More than 80 percent of the cost of ITER, about $22 billion or EUR18 billion, is contributed in the form of components manufactured by the partners. Many of these massive components of the ITER machine must be precisely fitted-for example, 17-meter-high magnets with less than a millimeter of tolerance. Each component must be ready on time to fit into the Master Schedule for machine assembly.

Members asked for this deal for three reasons. First, it means that most of the ITER costs paid by any member are actually paid to that member’s companies; the funding stays in-country. Second, the companies working on ITER build new industrial expertise in major fields-such as electromagnetics, cryogenics, robotics, and materials science. Third, this new expertise leads to innovation and spin-offs in other fields.

For example, expertise gained working on ITER’s superconducting magnets is now being used to map the human brain more precisely than ever before.

The European Union is paying 45 percent of the cost; China, India, Japan, Korea, Russia, and the United States each contribute 9 percent equally. All members share in ITER’s technology; they receive equal access to the intellectual property and innovation that comes from building ITER.

When will commercial fusion plants be ready?

ITER scientists predict that fusion plants will start to come on line as soon as 2040. The exact timing, according to fusion experts, will depend on the level of public urgency and political will that translates to financial investment.

How much power will they provide?

The ITER tokamak will produce 500 megawatts of thermal power. This size is suitable for studying a “burning” or largely self-heating plasma, a state of matter that has never been produced in a controlled environment on Earth. In a burning plasma, most of the plasma heating comes from the fusion reaction itself. Studying the fusion science and technology at ITER’s scale will enable optimization of the plants that follow.

A commercial fusion plant will be designed with a slightly larger plasma chamber, for 10-15 times more electrical power. A 2,000-megawatt fusion electricity plant, for example, would supply 2 million homes.

How much would a fusion plant cost and how many will be needed?

The initial capital cost of a 2,000-megawatt fusion plant will be in the range of $10 billion. These capital costs will be offset by extremely low operating costs, negligible fuel costs, and infrequent component replacement costs over the 60-year-plus life of the plant. Capital costs will decrease with large-scale deployment of fusion plants.

At current electricity usage rates, one fusion plant would be more than enough to power a city the size of Washington, D.C. The entire D.C. metropolitan area could be powered with four fusion plants, with zero carbon emissions.

“If fusion power becomes universal, the use of electricity could be expanded greatly, to reduce the greenhouse gas emissions from transportation, buildings and industry,” predicts Dr. Bigot. “Providing clean, abundant, safe, economic energy will be a miracle for our planet.”

** “Total construction work scope,” as used in ITER’s project performance metrics, includes design, component manufacturing, building construction, shipping and delivery, assembly, and installation.

It is an extraordinary project on many levels as Henry Fountain notes in a March 27, 2017 article for the New York Times (Note: Links have been removed),

At a dusty construction site here amid the limestone ridges of Provence, workers scurry around immense slabs of concrete arranged in a ring like a modern-day Stonehenge.

It looks like the beginnings of a large commercial power plant, but it is not. The project, called ITER, is an enormous, and enormously complex and costly, physics experiment. But if it succeeds, it could determine the power plants of the future and make an invaluable contribution to reducing planet-warming emissions.

ITER, short for International Thermonuclear Experimental Reactor (and pronounced EAT-er), is being built to test a long-held dream: that nuclear fusion, the atomic reaction that takes place in the sun and in hydrogen bombs, can be controlled to generate power.

ITER will produce heat, not electricity. But if it works — if it produces more energy than it consumes, which smaller fusion experiments so far have not been able to do — it could lead to plants that generate electricity without the climate-affecting carbon emissions of fossil-fuel plants or most of the hazards of existing nuclear reactors that split atoms rather than join them.

Success, however, has always seemed just a few decades away for ITER. The project has progressed in fits and starts for years, plagued by design and management problems that have led to long delays and ballooning costs.

ITER is moving ahead now, with a director-general, Bernard Bigot, who took over two years ago after an independent analysis that was highly critical of the project. Dr. Bigot, who previously ran France’s atomic energy agency, has earned high marks for resolving management problems and developing a realistic schedule based more on physics and engineering and less on politics.

The site here is now studded with tower cranes as crews work on the concrete structures that will support and surround the heart of the experiment, a doughnut-shaped chamber called a tokamak. This is where the fusion reactions will take place, within a plasma, a roiling cloud of ionized atoms so hot that it can be contained only by extremely strong magnetic fields.

Here’s a rendering of the proposed reactor,

It seems the folks at the New York Times decided to remove the notes which help make sense of this image. However, it does get the idea across.

If I read the article rightly, the official cost in March 2017 was around 22 B Euros and more will likely be needed. You can read Fountain’s article for more information about fusion and ITER or go to the ITER website.

I could have sworn a local (Vancouver area) company called General Fusion was involved in the ITER project but I can’t track down any sources for confirmation. The sole connection I could find is in a documentary about fusion technology,

Here’s a little context for the film from a July 4, 2017 General Fusion news release (Note: A link has been removed),

A new documentary featuring General Fusion has captured the exciting progress in fusion across the public and private sectors.

Let There Be Light made its international premiere at the South By Southwest (SXSW) music and film festival in March [2017] to critical acclaim. The film was quickly purchased by Amazon Video, where it will be available for more than 70 million users to stream.

Let There Be Light follows scientists at General Fusion, ITER and Lawrenceville Plasma Physics in their pursuit of a clean, safe and abundant source of energy to power the world.

The feature length documentary has screened internationally across Europe and North America. Most recently it was shown at the Hot Docs film festival in Toronto, where General Fusion founder and Chief Scientist Dr. Michel Laberge joined fellow fusion physicist Dr. Mark Henderson from ITER at a series of Q&A panels with the filmmakers.

Laberge and Henderson were also interviewed by the popular CBC radio science show Quirks and Quarks, discussing different approaches to fusion, its potential benefits, and the challenges it faces.

It is yet to be confirmed when the film will be release for streaming, check Amazon Video for details.

Brief final comment

ITER is a breathtaking effort but if you’ve read about other large scale projects such as building a railway across the Canadian Rocky Mountains, establishing telecommunications in an  astonishing number of countries around the world, getting someone to the moon, eliminating small pox, building the pyramids, etc., it seems standard operating procedure both for the successes I’ve described and for the failures we’ve forgotten. Where ITER will finally rest on the continuum between success and failure is yet to be determined but the problems experienced so far are not necessarily a predictor.

I wish the engineers, scientists, visionaries, and others great success with finding better ways to produce energy.

New energy (nuclear) with fusion at TED 2014′s Session 3: Reshape

Michel Laberge, plasma physicist and founder and Chief Scientist of company General Fusion, describes how his company is working to change our energy sources from fossil fuels to nuclear power (I wrote about General Fusion in a Dec. 2, 2011 posting).

He and his company are currently involved in a large international collaboration, ITER (China. European Union, India, Korea, Russia, and USA as per the website tagline) in the south of France. From the ITER project page (images not included),

ITER is a large-scale scientific experiment that aims to demonstrate that it is possible to produce commercial energy from fusion.

The Q in the formula on the right symbolizes the ratio of fusion power to input power. Q ≥ 10 represents the scientific goal of the ITER project: to deliver ten times the power it consumes. From 50 MW of input power, the ITER machine is designed to produce 500 MW of fusion power—the first of all fusion experiments to produce net energy.

During its operational lifetime, ITER will test key technologies necessary for the next step: the demonstration fusion power plant that will prove that it is possible to capture fusion energy for commercial use.

The science going on at ITER—and all around the world in support of ITER—will benefit all of mankind.

We firmly believe that to harness fusion energy is the only way to reconcile huge conflicting demands which will confront humanity sooner or later.

The issue at stake is how to reconcile the imperative, constantly growing demand of the majority of the world’s population to raise their standard of living … with the enormous environmental hazards resulting from the present energy supply …

… In our opinion, the use of fusion energy is a “must” if we want to be serious about embarking on sustainable development for future generations.

Laberge is speaking very quickly and since I’m not at all familiar with his area of expertise all I can say is he’s clearly very excited about his work and its potential to shift how we produce energy. He provides more than one technical explanation and I look forward to viewing his presentation again when it’s made public.

As for other speakers in this session. they were very interesting but as I noted yesterday I am am trying to focus on speakers whose topics have been covered here in one fashion or another.
