The new EPCOR Tower at Station Lands will become the company's downtown Edmonton headquarters. EPCOR Utilities Inc. ("EPCOR") has entered into a 20-year lease at Qualico's Station Lands, commencing January 1, 2012 or earlier.
EPCOR plans to occupy approximately 265,000 square feet on the top floors of the new 28-storey office tower, with options to scale its space requirements up or down during the term of the lease. The 20-year Lease secures enough space to meet EPCOR's current and long-term needs.
"The EPCOR Tower reflects the company's leadership and growth in the power and water business," said President & CEO Don Lowry.
EPCOR Tower will be certified to a Leadership in Energy and Environmental
Design (LEED(R)) Silver standard or higher, reducing energy, water and resource use. EPCOR's EnVest team will work with the developer to design an Environmental Stewardship Program for the building.
The Tower will bring all EPCOR's downtown employees into a single location, and offers a superior combination of environmental leadership, high quality and in-building amenities. "It will help EPCOR attract and retain the talented people the company needs to grow," Lowry continued, "and demonstrates environmental leadership."
Leases at the company's existing Edmonton offices expire at the end of 2011. EPCOR announced earlier in 2007 that it would be considering options for a new headquarters lease in downtown Edmonton. There are currently nearly 1,200 employees at EPCOR's downtown Edmonton offices, with the total projected to rise to 1,367 in 2012.
"EPCOR has more than doubled its revenues and dividend during the past ten years, doubled its employee count, and gone from operating 5 power and water plants to 50 across North America," Lowry explained. "The success to date, and our long-term vision for growth, means that EPCOR needs more space." EPCOR's Long Term Plan calls for capital spending of nearly $4 billion on new power and water projects over the next five years.
The EPCOR Tower will be located on 101st Street, between 104th and 105th Avenue, Northwest of the CN Tower and North of the surface parking lot at the corner of 104 Avenue and 101 Street.
Station Lands is a Qualico project designed by Kasian Architecture Interior Design and Planning Ltd. (Kasian), with construction management services to be provided by Ledcor Construction. The firms, as well as the project sub-consultants, have strong Edmonton roots.
PG&E Public Safety Power Shutoff reduces wildfire risk during extreme winds, triggering de-energization across the North Bay and Sierra Foothills under red flag warnings, with safety inspections and staged restoration to improve grid resilience.
Key Points
A utility protocol to de-energize lines during extreme fire weather, reducing ignition risks and improving grid safety.
✅ Triggered by red flag warnings, humidity, wind, terrain
✅ Temporary de-energization of transmission and distribution lines
✅ Inspections precede phased restoration to minimize wildfire risk
PG&E purposefully shut off electricity to nearly 60,000 Northern California customers Sunday night, aiming to mitigate wildfire risks from power lines during extreme winds.
Pacific Gas and Electric planned to restore power to 70 percent of affected customers in the North Bay and Sierra Foothills late Monday night. As crews inspect lines for safety by helicopter, vehicles and on foot, the remainder will have power sometime Tuesday.
While it was the first time the company shut off power for public safety, PG&E announced its criteria and procedures for such an event in June, said spokesperson Paul Doherty. After wildfires devastated Northern California's wine country last October, he added, PG&E developed its community wildfire safety program division to make power grids and communities more resilient, and prepares for winter storm season through enhanced local response.
Two sagging PG&E power lines caused one of those wildfires during heavy winds, killing four people and injuring a firefighter, the California Department of Forestry and Fire Protection determined earlier this month. Trees or tree branches hitting PG&E power lines started another four wildfires in October 2017. Altogether, the power company has been blamed for igniting 13 wildfires last year.
"We're adapting our electric system our operating practices to improve safety and reliability," Doherty said of the safety program. "That's really the bottom line for us."
Turning off power to so many customers was a "last resort given the extreme fire danger conditions these communities are experiencing," Pat Hogan, senior vice president of electric operations, said in a statement. Conditions that led the company to shut off power included the National Weather Service's red flag fire warnings, humidity levels, sustained winds, temperature, dry fuel and local terrain, Doherty said, amid possible rolling blackouts during grid strain.
The company de-energized more than 78 miles of transmission lines and more than 2,150 miles of distribution power lines Sunday night. Many schools in the area were closed Monday because of the planned power outage, highlighting unequal access to electricity across communities.
Late Saturday and early Sunday, PG&E warned 97,000 customers in 12 counties that the shut off might go into effect. Through automated calls, texts and emails, the company encouraged customers to have drinking water, canned food, flashlights, prescriptions and baby supplies on hand.
Power was also turned off in Southern California on Monday.
San Diego Gas & Electric turned off service to about 360 customers near Cleveland National Forest, where multiple fires have scorched large swaths of land in recent years.
SDG&E has pre-emptively shut off power to customers in the past, most recently in December when 14,000 customers went without power.
Southern California Edison, the primary electric provider across Southern California — including Los Angeles — has a similar power shutoff program. As of Monday night, SCE had yet to turn off power in any of its service areas, a spokesperson told USA TODAY.
Hurricane Michael Statistics track catastrophic wind speed, storm surge, rainfall totals, power outages, evacuations, and fatalities across Florida and the Southeast, detailing Category 4 intensity, Saffir-Simpson scale impacts, and emergency response resources.
Key Points
Hurricane Michael statistics detail wind speed, storm surge, rainfall, outages, and deaths from Category 4 landfall.
✅ 155 mph landfall winds; 14 ft storm surge; 12 in rainfall max
✅ 1.6M without power; 30,000 restoring crews; 6 states emergency
✅ 325k ordered evacuations; 32 deaths; FEMA and Guard deployed
Hurricane Michael, a historic Category 4 storm, struck the Florida Panhandle early Wednesday afternoon, unleashing heavy rain, high winds and a devastating storm surge.
Here is a look at the dangerous storm by the numbers:
155 mph: Wind speed -- nearly the highest possible for a Category 4 hurricane -- with which Michael made landfall near Mexico Beach and Panama City. A hurricane with 157 mph or higher is a Category 5, the strongest on the Saffir-Simpson hurricane wind scale.
129 mph: Peak wind gust reported Wednesday at Tyndall Air Force Base, which is about 12 miles southeast of Panama City, Florida.
32: Number of storm-related deaths attributed to Michael thus far, including an 11-year-old girl who local officials say was killed when part of a metal carport crashed into her family's mobile home in Lake Seminole, Georgia, and a 38-year-old man who was killed when a tree fell onto his moving car in Statesville, North Carolina.
Waves take over a house as Hurricane Michael comes ashore in Alligator Point, Fla., Oct. 10, 2018.
14 feet: Maximum height forecast for the storm surge when Michael's strong winds pushed the ocean water onto land. A storm surge just over 9 feet was reported Wednesday in Apalachicola, Florida.
12 inches: Isolated maximum amount of rain that Michael was expected to dump across the Florida Panhandle and the state's Big Bend region, as well as in southeast Alabama and parts of southwest and central Georgia.
9 inches: Maximum amount of rain that Michael could bring to isolated areas from Virginia to North Carolina.
1.6 million: Number of homes and businesses without power in Florida, Alabama, Georgia, South Carolina, North Carolina and Virginia as of Friday morning, a reminder that extended outages can persist after major disasters.
30,000: Number of workers mobilized from across the country to help restore power, underscoring the risks of field repairs such as line crew injuries during recovery.
6: Number of states that had emergency declarations in anticipation of Michael: Florida, Alabama, Georgia, South Carolina, North Carolina and Virginia.
325,000: Estimated number of people in the storm's path who were told to evacuate by local authorities.
6,000: Approximate number of people who stayed in the roughly 80 shelters across Florida, Alabama, Georgia, South Carolina and North Carolina on Wednesday night, while those sheltering at home were urged to avoid overheated power strips that can spark fires.
3,000: Number of personnel the Federal Emergency Management Agency deployed ahead of landfall, while utilities prepared on-site staffing plans to maintain operations during widespread disruptions.
35: Number of counties in Florida, of the state's 67, where Gov. Rick Scott declared a state of emergency prior to landfall, and grid reliability warnings often underscore systemic risks during national emergencies.
3,500: Number of Florida National Guard troops activated for pre-landfall coordination and planning, with an emphasis on high water and search-and-rescue operations.
600: Number of Florida state troopers assigned to the Panhandle and Big Bend region to assist with response and recovery efforts, including public reminders about downed line safety in affected communities.
500: Number of disaster relief workers that the American Red Cross was sending to affected areas in the Sunshine State.
200: Approximate number of patients being evacuated from at least two hospitals in Florida due to damage from the hurricane, highlighting how critical facilities depend on staff who have raised workforce safety concerns during other crises. Bay Medical Center Sacred Heart in Panama City said in a statement Thursday that its facility was damaged during the storm and thus is transferring more than 200 patients, including 39 who are critically ill, to regional hospitals. Gulf Coast Regional Medical Center, also in Panama City, announced in a statement Thursday that it's evacuating its roughly approximately patients, starting with the most critically ill, "because of the infrastructure challenges in our community."
MARVEL microreactor debuts at Idaho National Laboratory as a 100 kW, liquid-metal-cooled, zero-emissions generator powering a nuclear microgrid, integrating wind and solar for firm, clean energy in advanced nuclear applications research.
Key Points
A 100 kW, liquid-metal-cooled INL reactor powering a nuclear microgrid and showcasing zero-emissions clean energy.
✅ 100 kW liquid-metal-cooled microreactor at INL
✅ Powers first nuclear microgrid for applications testing
✅ Integrates with wind and solar for firm clean power
Inside the Transient Reactor Test Facility, a towering, windowless gray block surrounded by barbed wire, researchers are about to embark on a mission to solve one of humanity’s greatest problems with a tiny device.
Next year, they will begin construction on the MARVEL reactor. MARVEL stands for Microreactor Applications Research Validation and EvaLuation. It’s a first-of-a-kind nuclear power generator with a mini-reactor design that is cooled with liquid metal and produces 100 kilowatts of energy. By 2024, researchers expect MARVEL to be the zero-emissions engine of the world’s first nuclear microgrid at Idaho National Laboratory (INL).
“Micro” and “tiny,” of course, are relative. MARVEL stands 15 feet tall, weighs 2,000 pounds, and can fit in a semi-truck trailer. But it's minuscule compared to conventional nuclear power plants, which span acres, produces gigawatts of electricity to power whole states, and can take more than a decade to build.
For INL, where scientists have tested dozens of reactors over the decades across an area three-quarters the size of Rhode Island, it’s a radical reimagining of the technology. This advanced reactor design could help overcome the biggest obstacles to nuclear energy: safety, efficiency, scale, cost, and competition. MARVEL is an experiment to see how all these pieces could fit together in the real world.
“It’s an applications test reactor where we’re going to try to figure out how we extract heat and energy from a nuclear reactor and apply it — and combine it with wind, solar, and other energy sources,” said Yasir Arafat, head of the MARVEL program.
The project, however, comes at a time when nuclear power is getting pulled in wildly different directions, from phase-outs to new strategies like the UK’s green industrial revolution that shapes upcoming reactors.
Germany just shut down its last nuclear reactors. The U.S. just started up its first new reactor in 30 years, underscoring a shift. France, the country with the largest share of nuclear energy on its grid, saw its atomic power output decline to its lowest since 1988 last year. Around the world, there are currently 60 nuclear reactors under construction, with 22 in China alone.
But the world is hungrier than ever for energy. Overall electricity demand is growing: Global electricity needs will increase nearly 70 percent by 2050 compared to today’s consumption, according to the Energy Information Administration. At the same time, the constraints are getting tighter. Most countries worldwide, including the U.S., have committed to net-zero goals by the middle of the century, even as demand rises.
To meet this energy demand without worsening climate change, the U.S. Energy Department’s report on advanced nuclear energy released in March said, “the U.S. will need ~550–770 [gigawatts] of additional clean, firm capacity to reach net-zero; nuclear power is one of the few proven options that could deliver this at scale.”
The U.S. government is now renewing its bets on nuclear power to produce steady electricity without emitting greenhouse gases. The Bipartisan Infrastructure Law included $6 billion to keep existing nuclear power plants running. In addition, the Inflation Reduction Act, the U.S. government’s largest investment in countering climate change, includes several provisions to benefit atomic power, including tax credits for zero-emissions energy.
“It’s a game changer,” said John Wagner, director of INL.
The tech sector is jumping in, too, as atomic energy heats up across startups and investors. In 2021, venture capital firms poured $3.4 billion into nuclear energy startups. They’re also pouring money into even more far-out ideas, like nuclear fusion power. Public opinion has also started moving. An April Gallup poll found that 55 percent of Americans favour and 44 percent oppose using atomic energy, the highest levels of support in 10 years.
Ontario COVID-19 Business Tax Relief outlines permanent Employer Health Tax exemptions, lower Business Education Tax rates, optional municipal property tax cuts, and hydro bill subsidies to support small businesses, industrial and commercial recovery.
Key Points
A provincial package of tax breaks and hydro subsidies to help small, industrial, and commercial businesses recover.
✅ Permanent Employer Health Tax exemption to $1M payroll
✅ Lower Business Education Tax rates for 94% of firms
✅ Hydro subsidies cut medium-large rates by 14-16%
The Ontario government's latest plan to help businesses survive and recover from the COVID-19 pandemic includes a suite of new tax breaks for small businesses and $1.3 billion to subsidize electricity bills for industrial and commercial operations.
The new measures were announced Thursday as part of Ontario's 2020 budget, which sets new provincial records for both spending and deficit projections.
The government of Premier Doug Ford says the budget will address barriers impeding long-term growth, ensuring the province forges a path to a full recovery from the pandemic.
"When the pandemic is over, Ontario will come back with a vengeance, stronger and more prosperous than ever before," Ford said at an afternoon news conference.
Small businesses with payrolls under $1 million will no longer have to pay the Employer Health Tax. The province temporarily raised the exemption from $490,000 to $1 million earlier this year, but the government is now making the change permanent.
The higher exemption means that about 90 per cent of Ontario businesses will no longer have to pay the tax, amounting to about $360 million by 2022, according to the province.
"We have heard from employers across Ontario that this measure helped them keep workers on the job during COVID-19," Finance Minister Rod Phillips told the legislature.
The 2020 budget lowers rates for the Business Education Tax (BET), a property tax earmarked for public education. More than 200,000 Ontario businesses, or 94 per cent, will see a lower rate.
"I believe this budget takes some significant initial steps to help stabilize the economy and help businesses, especially small businesses," said Toronto Mayor John Tory in a statement. Tory's office estimates that reductions to the BET will result in $117 million in lower taxes for commercial properties in Canada's largest city.
Municipal governments will also be permitted to reduce property taxes for small businesses, should they choose to do so. The province says it will "consider matching these reductions," which could amount to $385 million in tax relief by 2023.
Finance Minister Rod Phillips tabled the largest spending plan in Ontario history on Thursday afternoon. (Frank Gunn/The Canadian Press) Municipalities currently have few options to provide targeted relief to local businesses. Guelph Mayor Cam Guthrie, chair of Ontario's Big City Mayors, said the prospect of lowering property taxes will likely be welcomed by local governments across the province.
"I really am looking forward to looking into that because it would give targeted relief to these businesses that have been asking for something from local governments for the past nine months," he said in an interview.
Tax cuts 'won't help a boarded up business,' NDP says The 2020 budget does not contain any new direct funding for small businesses or their employees. NDP leader Andrea Horwath, who has proposed to make hydro public again, said those types of funding would help businesses more than potential tax reductions.
"A future hydro or tax cut won't help a boarded up business and it certainly won't help the folks that used to work there," Horwath said.
"Those measures are great if you're a company that's doing really well ... but let's face it, main streets across Ontario are crumbling."
Ontario did reveal on Thursday more details about a previously announced $300-million fund to support businesses in Toronto, Ottawa, Peel Region and York Region, which were placed under modified Stage 2 restrictions this fall. The money can be used to cover property taxes and energy bills for eligible businesses.
An undetermined amount of the $300 million will also be made available to businesses that are placed under "control" and "lockdown" rules, which are the two most severe restrictions in the province's updated reopening guidelines announced in October.
No regions are currently under these restrictions.
Government to subsidize hydro bills for industrial businesses The Ford government, which earlier oversaw a Hydro One leadership overhaul, is also taking aim at what it calls "job-killing electricity prices" in Ontario's industrial and commercial sectors.
The budget includes a $1.3 billion investment over three years to subsidize their hydro bills, a move praised by Canadian Manufacturers & Exporters as supportive of industry, which the province says have been inflated due to contracts signed by the previous Liberal government to purchase electricity generated by wind, solar and bioenergy.
"This is the legacy that is making our businesses uncompetitive," Phillips told reporters Thursday afternoon.
Ontario says its $1.3-billion investment to subsidize electricity bills will offset expensive contracts for green energy signed by the previous Liberal government. (Patrick Pleul/dpa via Associated Press) The investment will lower rates for medium- and large-sized business by between 14 and 16 per cent, and follows an OEB decision on Hydro One rates that affects transmission and distribution costs, according to Ontario's calculations. Phillips said those rates will be among the lowest of any jurisdiction in the Great Lakes region.
The provincial government said the investment is necessary for Ontario to recover from the COVID-19 downturn. The Ford government expects that no further subsidies will be required by around 2040.
Hydro-Quebec Crypto Mining Pause signals a temporary halt as blockchain power requests surge; energy regulator review will weigh electricity demand, winter peak constraints, tariffs, investments, and local jobs to optimize grid stability and revenues.
Key Points
A provincial halt on new miner power requests as Hydro-Quebec sets rules to safeguard demand, winter peaks, and rates.
✅ Temporary halt on new electricity sales to crypto miners
✅ Regulator to rank projects by jobs, investment, and revenue
✅ Winter peak demand and tariffs central to new framework
Major Canadian electricity provider Hydro-Québec will temporarily stop processing requests from cryptocurrency miners in order for the company to fulfil its obligations to supply energy to the entire province, while its global ambitions adjust to changing demand, according to a press release published June 7.
Hydro-Québec is experiencing “unprecedented” demand from blockchain companies, which reportedly exceeds the electric utility’s short and medium-term capacity. In this regard, the Quebec provincial government has ordered Hydro-Québec to halt electric power sales to cryptocurrency miners, and, following the New Hampshire rejection of Northern Pass announced a new framework for this category of electricity consumers.
In the coming days, Hydro-Québec will reportedly file an application to local energy regulator Régie de l'énergie, proposing a selection process for blockchain industry projects so as “not to miss the opportunities offered by this industry.” Regulators will reportedly target companies which can offer the province the most profitable economic advantages, including investments and local job creation.
#google#
Régie de l'énergie is instructed to consider “the need for a reserved block of energy for this category of consumers, the possibility of maximizing Hydro-Québec's revenues, and issues related to the winter peak period” as well as interprovincial arrangements like the Ontario-Québec electricity deal under discussion. Éric Filion, President of Hydro-Québec Distribution, said:
"The blockchain industry is a promising avenue for Hydro-Québec. Guidelines are nevertheless required to ensure that the development of this industry maximizes spinoffs for Québec without resulting in rate increases for our customers. We are actively participating in the Régie de l'énergie's process so that these guidelines can be produced as quickly as possible."
With this move, the government of Québec deviates from its decision to reportedly open the electricity market to miners at the end of last month, even as an Ontario-Quebec energy swap helps manage electricity demands. In March, the government said it was not interested in providing cheap electricity to Bitcoin miners, stating that cryptocurrency mining at a discount without any sort of “added value” for the local economy was unfavorable.
ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.
Key Points
ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.
✅ Tokamak magnetic confinement with high-temp superconducting coils
✅ Deuterium-tritium fuel cycle with on-site tritium breeding
✅ Targets net energy gain and grid-scale, low-carbon electricity
It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.
Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.
But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.
“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.
Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.
Constructing a nuclear fusion reactor ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.
The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.
When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.
Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.
In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.
A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.
One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat
The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.
“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.
The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.
“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.
Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.
Choosing a fuel Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.
Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.
At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.
The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.
“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”
