Cruise ships may soon be able to cut their engines and plug into the BC Hydro grid when they're docked at Canada Place.
A proposal going to the Metro Vancouver environment and energy committee would make "port electrification" a priority for the region due to ongoing concerns about the effect of ship diesel emissions on local air quality and human health.
At present, seagoing vessels including cruise, container and other cargo ships keep their engines running in port in order to generate electrical power for on-board lights and other systems.
Collectively, ship exhaust emissions comprise one of the biggest sources of air pollution in the Metro-Fraser Valley region — port electrification would allow marine vessels to switch off their engines and plug into the grid instead.
The biggest snag is an absence of federal dollars — $4 million is needed to bolster contributions from the Metro Vancouver port authority, the region, the marine industry and the province.
Port Metro Vancouver hopes to see cruise ships plugged in for the 2009 summer season - Holland America and Princess Cruises already have plug-in ships plying the west coast.
Metro committee chair Joe Trasolini noted that with a federal election underway, it's an opportune time for the locals to lock in a commitment for the cash.
"I've been harping at this for three years, but it seems to be an opportune time now," said Trasolini, who will be standing for reelection as mayor of Port Moody in November's municipal elections.
"We are doing a lot to try to reduce greenhouse gas emissions and particulate matter emissions and so on, all of the things that affect the airshed. Yet there was one area where we saw exponential growth with nothing to abate it. That was emissions originating from marine vessels," Trasolini said in an interview.
"The objective is to have onshore power right across the Metro Vancouver port — but as a first step we have to power up the cruise ship industry, who seem to be more in the public eye and more willing to comply with our requests."
John Hansen, president of the NorthWest CruiseShip Association noted that the first shore plug terminal on the west coast was established at Juno, Alaska, in 2002.
"Since then Seattle has provided shore power plug in for two of their three berths. Holland America and Princess Cruise ships are able to plug-in in Seattle.
"We are certainly aware that there's a lot of interest in California, in Long Beach, in San Pedro, in San Francisco and San Diego to follow suit.
"We're certainly excited about the prospect of having that capability in Vancouver as well."
Hansen said that if you discount the capital investment needed to install a transformer on a ship in order to plug into the grid, the cost of electricity from shore power and diesel generation is roughly equal.
Darryl Desjardins, environmental programs director for Port Metro Vancouver said the port hopes that within 15 years, the capital stock rollover among international shipping lines will lead to all ships coming into the Vancouver port with the capability to plug into the grid.
"In the inner harbour, the Vanterm and Centerm container terminals already have the infrastructure in place to allow for the electrical wiring to go to the dockside, and when the Deltaport third berth project is complete at Roberts Bank, that will also have the infrastructure in place for shore power," Desjardins said in an interview.
He said the port is also looking at projects such as wind and tidal power generation to produce enough electricity to feed ships without drawing on the BC Hydro grid.
The port authority has applied formally to BC Hydro for an interconnecting service, and Hydro must obtain consent from the B.C. Utilities Commission in order to develop a pricing scheme for the seagoing customers.
Hydro spokeswoman Susan Danard said that the power would be provided to ships on an "interruptible" basis — in other words, Hydro will reserve the ability to cut their supply if demand spikes from their regular customers.
Bangladesh Rooppur Nuclear Power Plant advances nuclear energy with IAEA support and ROSATOM construction, boosting energy security, baseload capacity, and grid reliability; 2400 MW units aid development, regulatory compliance, and newcomer infrastructure milestones.
Key Points
A 2400 MW nuclear project in Rooppur, built with IAEA guidance and ROSATOM, to boost Bangladesh's reliable power.
✅ Two units totaling 2400 MW for stable baseload supply
✅ IAEA Milestones and INIR reviews guide safe deployment
✅ ROSATOM builds; national regulator strengthens oversight
The beginning of construction at Bangladesh’s first nuclear power reactor on 30 November 2017 marked a significant milestone in the decade-long process to bring the benefits of nuclear energy to the world’s eighth most populous country. The IAEA has been supporting Bangladesh on its way to becoming the third ‘newcomer’ country to nuclear power in 30 years, following the United Arab Emirates in 2012 and Belarus in 2013.
Bangladesh is in the process of implementing an ambitious, multifaceted development programme to become a middle-income country by 2021 and a developed country by 2041. Vastly increased electricity production, with the goal of connecting 2.7 million more homes to the grid by 2021, is a cornerstone of this push for development, and nuclear energy will play a key role in this area, said Mohammad Shawkat Akbar, Managing Director of Nuclear Power Plant Company Bangladesh Limited. Bangladesh is also working to diversify its energy supply to enhance energy security, reduce its dependence on imports and on its limited domestic resources, he added.
#google# In the region, India's nuclear program is taking steps to get back on track, underscoring broader momentum.
“Bangladesh is introducing nuclear energy as a safe, environmentally friendly and economically viable source of electricity generation,” said Akbar. The plant in Rooppur, 160 kilometres north-west of Dhaka, will consist of two units, with a combined power capacity of 2400 MW(e). It is being built by a subsidiary of Russia’s State Atomic Energy Corporation ROSATOM. The first unit is scheduled to come online in 2023 and the second in 2024, reflecting progress similar to the UK's latest nuclear power station developments. “This project will enhance the development of the social, economic, scientific and technological potential of the country,” Akbar said.
The country’s goal of increased electricity production via nuclear energy will soon be a reality, Akbar said. “For 60 years, Bangladesh has had a dream of building its own nuclear power plant. The Rooppur Nuclear Power Plant will provide not only a stable baseload of electricity, but it will enhance our knowledge and allow us to increase our economic efficiency.
Milestones for nuclear
Bangladesh is among around 30 countries that are considering, planning or starting the introduction of nuclear power, with milestones at nuclear projects worldwide offering context for this progress. The IAEA assists them in developing their programmes through the Milestones Approach — a methodology that provides guidance on working towards the establishment of nuclear power in a newcomer country, including the associated infrastructure. It focuses on pointing out gaps, if any, in countries’ progress towards the introduction of nuclear power.
The IAEA has been supporting Bangladesh in developing its nuclear power infrastructure, including in establishing a regulatory framework and developing a radioactive waste-management system. This support has been delivered under the IAEA technical cooperation programme and is partially funded through the Peaceful Uses Initiative.
Nuclear infrastructure is multifaceted, containing governmental, legal, regulatory and managerial components, in addition to the physical infrastructure. The Milestones Approach consists of three phases, with a milestone to be reached at the end of each.
The first phase involves considerations before a decision is taken to start a nuclear power programme and concludes with the official commitment to the programme. The second phase entails preparatory work for the contracting and construction of a nuclear power plant, as seen in Bulgaria's nuclear project planning, ending with the commencement of bids or contract negotiations for the construction. The final phase includes activities to implement the nuclear power plant, such as the final investment decision, contracting and construction. The duration of these phases varies by country, but they typically take between 10 and 15 years.
“The IAEA Milestones Approach is a guiding document and the Integrated Work Plan (IWP) is the important means of bringing all of the stakeholders in Bangladesh together to ensure the fulfilment of all safety, security, and safeguards requirements of the Rooppur NPP project,” said Akbar. “This IWP enabled Bangladesh to develop a holistic approach to implementing IAEA guidance as well as cooperating with national stakeholders and other bilateral partners towards the development of a national nuclear power programme.”

INIR Mission
The Integrated Nuclear Infrastructure Review (INIR) is a holistic peer review to assist Member States in assessing the status of their national infrastructure for introducing nuclear power. The IAEA completed its first INIR mission to Bangladesh in November 2011, making recommendations on how to develop a plan to establish the nuclear infrastructure. Nearly five years later, in May 2016, a follow-up mission was conducted, which noted the progress made — Bangladesh had established a nuclear regulatory body, had chosen a site for the power plant and had completed site characterization and environmental impact assessment.
“The IAEA and other bodies, including those from experienced countries, can and do provide support, but the responsibility for safety and security will lie with the Government,” said Dohee Hahn, Director of the IAEA’s Division of Nuclear Power, at the ceremony for the pouring of the first nuclear safety-related concrete at Rooppur on 30 November 2017. “The IAEA stands ready to continue supporting Bangladesh in developing a safe, secure, peaceful and sustainable nuclear power programme.”

"Exciting times for nuclear power," IAEA Director General Says
Germany Hydrogen Import Strategy outlines reliance on green hydrogen imports, expanded electrolysis capacity, IPCEI-funded pipelines, and industrial decarbonization for steel and chemicals to reach climate-neutral goals by 2045, meeting 2030 demand of 95-130 TWh.
Key Points
A plan to import 50-70% of hydrogen by 2030, backing green hydrogen, electrolysis, pipelines, and decarbonization.
✅ Imports cover 50-70% of 2030 hydrogen demand
✅ 10 GW electrolysis target with state aid and IPCEI
✅ 1,800 km H2 pipelines to link hubs by 2030
Germany will have to import up to 70% of its hydrogen demand in the future as Europe's largest economy aims to become climate-neutral by 2045, an updated government strategy published on Wednesday showed.
The German cabinet approved a new hydrogen strategy, setting guidelines for hydrogen production, transport infrastructure and market plans.
Germany is seeking to expand reliance on hydrogen as a future energy source to bolster energy resilience and cut greenhouse emissions for highly polluting industrial sectors that cannot be electrified such as steel and chemicals and cut dependency on imported fossil fuel.
Produced using solar and wind power, green hydrogen is a pillar of Berlin's plan to build a sustainable electric planet and transition away from fossil fuels.
But even with doubling the country's domestic electrolysis capacity target for 2030 to at least 10 gigawatts (GW), Germany will need to import around 50% to 70% of its hydrogen demand, forecast at 95 to 130 TWh in 2030, the strategy showed.
"A domestic supply that fully covers demand does not make economic sense or serve the transformation processes resulting from the energy transition and the broader global energy transition overall," the document said.
The strategy underscores the importance of diversifying future hydrogen sources, including potential partners such as Canada's clean hydrogen sector, but the government is working on a separate strategy for hydrogen imports whose exact date is not clear, a spokesperson for the economy ministry said.
"Instead of relying on domestic potential for the production of green hydrogen, the federal government's strategy is primarily aimed at imports by ship," Simone Peter, the head of Germany's renewable energy association, said.
Under the strategy, state aid is expected to be approved for around 2.5 GW of electrolysis projects in Germany this year and the government will earmark 700 million euros ($775 million) for hydrogen research to optimise production methods, research minister Bettina Stark-Watzinger said.
But Germany's limited renewable energy space will make it heavily dependent on imported hydrogen from emerging export hubs such as Abu Dhabi hydrogen exports gaining scale, experts say.
"Germany is a densely populated country. We simply need space for wind and photovoltaic to be able to produce the hydrogen," Philipp Heilmaier, an energy transition researcher at Germany energy agency, told Reuters.
The strategy allows the usage of hydrogen produced through fossil energy sources preferably if the carbon is split off, but said direct government subsidies would be limited to green hydrogen.
Funds for launching a hydrogen network with more than 1,800 km of pipelines in Germany are expected to flow by 2027/2028 through the bloc's Important Projects of Common European Interest (IPCEI) financing scheme, as the EU plans to double electricity use by 2050 could raise future demand, with the goal of connecting all major generation, import and storage centres to customers by 2030.
Transport Minister Volker Wissing said his ministry was working on plans for a network of hydrogen filling stations and for renewable fuel subsidies.
Environmental groups said the strategy lacked binding sustainability criteria and restriction on using hydrogen for sectors that cannot be electrified instead of using it for private heating or in cars, calling for a plan to eventually phase-out blue hydrogen which is produced from natural gas.
Germany has already signed several hydrogen cooperation agreements with countries such as clean energy partnership with Canada and Norway, United Arab Emirates and Australia.
Global Decarbonization Strategies align renewable energy, electrification, clean air policies, IMO sulfur cap, LNG fuels, and the EU 2050 roadmap to cut carbon intensity and meet Paris Agreement targets via EVs and efficiency.
Key Points
Frameworks that cut emissions via renewables, EVs, efficiency, cleaner marine fuels, and EU policy roadmaps.
✅ Renewables scale as wind and solar outcompete new coal and gas.
✅ Electrification of transport grows as EV costs fall and charging expands.
✅ IMO 2020 sulfur cap and LNG shift cut shipping emissions and particulates.
Are we doing enough to save the planet? Silly question. The latest prognosis from the United Nations’ Intergovernmental Panel on Climate Change made for gloomy reading. Fundamental to the Paris Agreement is the target of keeping global average temperatures from rising beyond 2°C. The UN argues that radical measures are needed, and investment incentives for clean electricity are seen as critical by many leaders to accelerate progress to meet that target.
Renewable power and electrification of transport are the pillars of decarbonization. It’s well underway in renewables - the collapse in costs make wind and solar generation competitive with new build coal and gas.
Renewables’ share of the global power market will triple by 2040 from its current level of 6% according to our forecasts.
The consumption side is slower, awaiting technological breakthrough and informed by efforts in countries such as New Zealand’s electricity transition to replace fossil fuels with electricity. The lower battery costs needed for electric vehicles (EVs) to compete head on and displace internal combustion engine (ICE) cars are some years away. These forces only start to have a significant impact on global carbon intensity in the 2030s. Our forecasts fall well short of the 2°C target, as does the IEA’s base case scenario.
Yet we can’t just wait for new technology to come to the rescue. There are encouraging signs that society sees the need to deal with a deteriorating environment. Three areas of focus came out in discussion during Wood Mackenzie’s London Energy Forum - unrelated, different in scope and scale, each pointing the way forward.
First, clean air in cities. China has shown how to clean up a local environment quickly. The government reacted to poor air quality in Beijing and other major cities by closing older coal power plants and forcing energy intensive industry and the residential sector to shift away from coal. The country’s return on investment will include a substantial future health care dividend.
European cities are introducing restrictions on diesel cars to improve air quality. London’s 2017 “toxicity charge” is a precursor of an Ultra-Low Emission Zone in 2019, and aligns with UK net-zero policy changes that affect transport planning, to be extended across much of the city by 2020. Paris wants to ban diesel cars from the city centre by 2025 and ICE vehicles by 2030. Barcelona, Madrid, Hamburg and Stuttgart are hatching similar plans.
College Promise In California: Community-Wide Efforts To Support Student Success
Second, desulphurisation of global shipping. High sulphur fuel oil (HSFO) meets around 3.5 million barrels per day (b/d) of the total marine market of 5 million b/d. A maximum of 3.5% sulphur content is allowed currently. The International Maritime Organisation (IMO) implements a 0.5% limit on all shipping in 2020, dramatically reducing the release of sulphur oxides into the atmosphere.
Some ships will switch to very low sulphur fuel oil, of which only around 1.4 million b/d will be available in 2020. Others will have to choose between investing in scrubbers or buying premium-priced low sulphur marine gas oil.
Longer-term, lower carbon-intensity gas is a winner as liquefied natural gas becomes fuel of choice for many newbuilds. Marine LNG demand climbs from near zero to 50 million tonnes per annum (tpa) by 2040 on our forecasts, behind only China, India and Japan as a demand centre. LNG will displace over 1 million b/d of oil demand in shipping by 2040.
Third, Europe’s radical decarbonisation plans. Already in the vanguard of emissions reductions policy, the European Commission is proposing to reduce carbon emissions for new cars and vans by 30% by 2030 versus 2020. The targets come with incentives for car manufacturers linked to the uptake of EVs.
The 2050 roadmap, presently at the concept stage, envisages a far more demanding regime, with EU electricity plans for 2050 implying a much larger power system. The mooted 80% reduction in emissions compared with 1990 will embrace all sectors. Power and transport are already moving in this direction, but the legacy fuel mix in many other sectors will be disrupted, too.
Near zero-energy buildings and homes might be possible with energy efficiency improvements, renewables and heat pumps. Electrification, recycling and bioenergy could reduce fossil fuel use in energy intensive sectors like steel and aluminium, and Europe’s oil majors going electric illustrates how incumbents are adapting. Some sectors will cite the risk decarbonisation poses to Europe’s global competitiveness. If change is to come, industry will need to build new partnerships with society to meet these targets.
The 2050 roadmap signals the ambition and will be game changing for Europe if it is adopted. It would provide a template for a global roll out that would go a long way toward meeting UN’s concerns.
Manitoba Hydro unpaid leave plan offers unpaid days off to curb workforce costs amid COVID-19, avoiding temporary layoffs and pay cuts, targeting $5.7M savings through executive, manager, and engineer participation, with union options under discussion.
Key Points
A cost-saving measure offering unpaid days off to avert layoffs and pay cuts, targeting $5.7M savings amid COVID-19.
✅ 3 unpaid days for executives, managers, engineers
✅ Targets $5.7M total; $1.4M from non-union staff
✅ Avoids about 240 layoffs over a four-month period
The Manitoba government's Crown energy utility is offering workers unpaid days off as an alternative to temporary layoffs or pay cuts, even as residential electricity use rises due to more working from home.
In an email to employees, Manitoba Hydro president Jay Grewal says executives, managers, and engineers will take three unpaid days off before the fiscal year ends next March.
She says similar options are being discussed with other employee groups, which are represented by unions, as the Saskatchewan COVID-19 crisis reshaped workforces across the Prairies.
The provincial government ordered Manitoba Hydro to reduce workforce costs during the COVID-19 pandemic, as some power operators considered on-site staffing plans, and at one point the utility said it was looking at 600 to 700 temporary layoffs.
The organization said it’s looking for targeted savings of $5.7 million, down from $11 million previously estimated, while peers like BC Hydro’s Site C began reporting COVID-19 updates.
A spokesperson for Manitoba Hydro said non-unionized staff taking three days of unpaid leave will save $1.4 million of the $5.7 million savings.
“Three days of unpaid leave for every employee would eliminate layoffs entirely,” the spokesperson said in an email. “For comparison, approximately 240 layoffs would have to occur over a four-month period, while measures like Alberta's worker transition fund aim to support displaced workers, to achieve savings of $4.3 million.”
Grewal says the unpaid days off were a preferred option among the executives, managers, and engineers in an industry that recently saw a Hydro One worker injury case.
She says unions representing the other workers have been asked to respond by next Wednesday.
Smart Meter Texas real-time pricing faces rollback as utilities limit on-demand reads, impacting demand response, home area networks, ERCOT wholesale tracking, and thermostat automation, reducing efficiency gains promised through deregulation and smart meter investments.
Key Points
A plan linking smart meters to ERCOT prices, enabling near real-time usage alignment and automated demand response.
✅ Twice-hourly reads miss 15-minute ERCOT price spikes.
✅ Less than 1% of 7.3M meters use HAN real-time features.
✅ Limits hinder automation for HVAC, EV charging, and pool pumps.
Utilities made a promise several years ago when they built Smart Meter Texas that they’d come up with a way for consumers to monitor their electricity use in real time. But now they’re backing out of the deal with the approval of state regulators, leaving in the lurch retail power companies that are building their business model on the promise of real time pricing and denying consumers another option for managing their electricity costs.
Texas utilities collected higher rates to finance the building of a statewide smart meter network that would allow customers to track their electricity use and the quickly changing prices on wholesale power markets almost as they happened. Some retailers are building electricity plans around this promise, providing customers with in-home devices that would eventually track pricing minute-by-minute and allow them to automatically turn down or shut off air conditioners, pool pumps and energy sucking appliances when prices spiked on hot summer afternoons and turn them back on when they prices fell again.
The idea is to help save consumers money by allowing them to shift their electricity consumption to periods when power is cheaper, typically nights and weekends, even as utility revenue in a free-power era remains a debated topic.
“We’re throwing away a large part of (what) ratepayers paid for,” said John Werner, CEO of GridPlus Texas, one of the companies offering consumers a real-time pricing plan that is scheduled to begin testing next month. “They made the smart meters dumb meters.”
When Smart Meter Texas was launched a decade ago by a consortium of the state’s biggest utilities, it was considered an important part of deregulation. The competitive market for electricity held the promise that consumers would eventually have the technology to control their electricity use through a home area network and cut their power bills.
Regulators and legislators also were enticed by the possibility of making the electric system more efficient and relieving pressure on the power grid as consumers responded to high prices and cut consumption when temperatures soared, with ongoing discussions about Texas grid reliability informing policy choices.
One study found that smart meters coupled with smart real time consumption monitors could reduce electricity use between 3 percent and 5 percent, according to Call Me Power, a website sponsored by the European electricity price shopping service Selectra.
But utilities complained that the home area network devices were expensive to install and not used very often, and, with flat electricity demand weighing on growth, they questioned further investment. CenterPoint manager Esther Floyd Kent filed an affidavit with the commission in May that it costs the utility about $30,000 annually to support the network devices, plus maintenance.
Over a six-year period, CenterPoint paid $124,500, or about $20,000 a year, to maintain the system. As of April, there were only 4,067 network devices in CenterPoint’s service area, meaning the utility pays about $30.70 each year to maintain each device.
Centerpoint last year generated $9.6 billion in revenues and earned a $1.8 billion profit, according to its financial filings. CenterPoint officials did not respond to requests for comment.
Other utilities that are part of the Smart Meter consortium also complained to the Public Utility Commission that, up to now, the system hasn’t developed. All told, Texas has 7.3 million meters connected to Smart Meter Texas, but less than 1 percent are using the networking functions to track real-time prices and consumption, according to the testimony of Donny R. Helm, director of technology strategy and architecture for the state’s largest utility Oncor Electric Delivery Co. in Dallas.
The isssue was resolved recently through a settlement agreement that limits on-demand readings to twice an hour that Smart Meter Texas must provide customers. The price of power changes every 15 minutes, so a twice an hour reading may miss some price spikes.
The Public Utility Commission signed off on the deal, and so did several other groups including several retail electricity providers and the Office of Public Utility Counsel which represents residential customers and small businesses.
Michele Gregg, spokeswoman for the Public Utility Counsel, testified in December that the consumer advocate supported the change because widespread use of the networks never materialized. Catherine Webking, an Austin lawyer who represents the Texas Energy Association for Marketers, a group of retail electric providers, said she believes the deal was a reasonable resolution of providing the benefits of Smart Meter Texas while not incurring too much cost.
But Griddy, an electricity provider that offers customers the opportunity to pay wholesale power prices, which also issued a plea to customers during a price surge, said the state hasn’t given the smart-meter networks a chance and could miss out on its potential. Griddy was counting on the continued adoption of real time pricing as the next step for customers wanting to control their electricity costs.
Right now, Griddy sends out price alerts from the grid operator Electric Reliability Council of Texas so businesses like hotels can run washers and dryers when electricity prices are cheapest. But the company was counting on a smart-meter program that would allow customers to track wholesale prices and manage consumption themselves, making Griddy’s offerings attractive to more people.
Wholesale prices are generally cheaper than retail prices, but they can fluctuate widely, especially when the Texas power grid faces another crisis during extreme weather. Last year, wholesale prices averaged less than 3 cents per kilowatt hour, much lower than than retail rates that now are running above 11 cents, but they can spike at times of high demand to as much as $9 a kilowatt hour.
What customers want is to be able to use energy when it’s cheapest, said Greg Craig, Griddy’s CEO, and they want to do it automatically. They want to be able to program their thermostat so that if the price rises they can shut off their air conditioning and if the price falls, they can charge their electric-powered vehicle.
Griddy customers may still save money even without real time data, he said. But they won’t be able to see their usage in real time or see how much they’re spending.
“The big utilities have big investments in the existing way and going to real time and more transparency isn’t really in their best interest,” said Craig.
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.”
