Clean energy sector creates 1,400 new jobs

Enel Green Power España Aragon wind farms advance Spain's renewable energy transition, with 90MW under construction in Teruel, Endesa investment of €88 million, 25-50MW turbines, and 2017 auction-backed capacity enhancing grid integration and clean power.

Key Points

They are three Teruel wind projects totaling 90MW, part of Endesa's 2017-awarded plan expanding Spain's clean energy.

✅ 90MW across Sierra Costera I, Allueva, and Sierra Pelarda

✅ €88m invested; 14+7+4 turbines; Endesa-led build in Teruel

✅ Part of 2017 tender: 540MW wind, 339MW solar, nationwide

Enel Green Power Espana, part of Enel's wind projects worldwide, has started constructing three wind farms in Aragon, north-east Spain, which are due online by the end of the year.

The projects, all situated in the Teruel province, are worth a total investment of €88 million.

The biggest of the facilities, Sierra Costera I, will have a 50MW and will feature 14 turbines.

The wind farm is spread across the municipalities of Mezquita de Jarque, Fuentes Calientes, Canada Vellida and Rillo.

The Allueva wind facility will feature seven turbines and will exceed 25MW.

Sierra Pelarda, in Fonfria, will have four turbines and a capacity of 15MW, as advances in offshore wind turbine technology continue to push scale elsewhere.

The projects bring the total number of wind farms that Enel Green Power Espana has started building in the Teruel province to six, equal to an overall capacity of 218MW.

Endesa chief executive Jose Bogas said: “These plants mark the acceleration on a new wave of growth in the renewable energy space that Endesa is committed to pursue in the next years, driving the energy transition in Spain.”

The six wind farms under construction in Teruel are part of the 540MW that Enel Green Power Espana was awarded in the Spanish government's renewable energy tender held in May 2017.

In Aragon, the company will invest around €434 million euros, reflecting broader European wind power investment trends in recent years, to build 13 wind farms with a total installed capacity of more than 380MW.

The remaining 160MW of wind capacity will be located in Andalusia, Castile-Leon, Castile La Mancha and Galicia, even as some Spanish turbine factories closed during pandemic restrictions.

Enel Green Power Espana was also awarded 339MW of solar capacity in the Spanish government's auction held in July 2017, while other Spanish developers advance CSP projects abroad in markets like Chile.

Once all wind and solar under the 2017 tender are complete they will boost the company’s capacity by around 52%.

Atlantic Canada EV adoption lags, a new poll finds, as fewer buyers consider electric vehicles amid limited charging infrastructure, lower provincial rebates, and affordability pressures in Nova Scotia and Newfoundland compared to B.C. and Quebec.

Key Points

Atlantic Canada EV adoption reflects demand, shaped by rebates, charging access, costs, and the regional energy mix.

✅ Poll shows lowest purchase intent in Atlantic Canada

✅ Lack of rebates and charging slows EV consideration

✅ Income and energy mix affect affordability and benefits

Atlantic Canadians are the least likely to buy a car, truck or SUV in the next year and the most skittish about going electric, according to a new poll. 

Only 31 per cent of Nova Scotians are looking at buying a new or used vehicle before December 2021 rolls around. And just 13 per cent of Newfoundlanders who are planning to buy are considering an electric vehicle. Both those numbers are the lowest in the country. Still, 47 per cent of Nova Scotians considering buying in the next year are thinking about electric options, according to the numbers gathered online by Logit Group and analyzed by Halifax-based Narrative Research. That compares to 41 per cent of Canadians contemplating a vehicle purchase within the next year, with 54 per cent of them considering going electric. 

“There’s still a high level of interest,” said Margaret Chapman, chief operating officer at Narrative Research.  

“I think half of people who are thinking about buying a vehicle thinking about electric is pretty significant. But I think it’s a little lower in Atlantic Canada compared to other parts of the country probably because the infrastructure isn’t quite what it might be elsewhere. And I think also it’s the availability of vehicles as well. Maybe it just hasn’t quite caught on here to the extent that it might have in, say, Ontario or B.C., where the highest level of interest is.” 

Provincial rebates
Provincial rebates also serve to create more interest, she said, citing New Brunswick's rebate program as an example in the region. 

“There’s a $7,500 rebate on top of the $5,000 you get from the feds in B.C. But in Nova Scotia there’s no provincial rebate,” Chapman said. “So I think that kind of thing actually is significant in whether you’re interested in buying an electric vehicle or not.” 

The survey was conducted online Nov. 11–13 with 1,231 Canadian adults. 

Of the people across Canada who said they were not considering an electric vehicle purchase, 55 per cent said a provincial rebate would make them more likely to consider one, she said.  

In Nova Scotia, that number drops to 43 per cent. 

Nova Scotia families have the lowest median after-tax income in the country, according to numbers released earlier this year.  

The national median in 2018 was $61,400, according to Statistics Canada. Nova Scotia was at the bottom of the pack with $52,200, up from $51,400 in 2017. 

So big price tags on electric vehicles might put them out of reach for many Nova Scotians, and a recent cost-focused survey found similar concerns nationwide. 

“I think it’s probably that combination of cost and infrastructure,” Chapman said. 

“But you saw this week in the financial update from the federal government that they’re putting $150 million into new charging station, so were some of that cash to be spread in Atlantic Canada, I’m sure there would be an increase in interest … The more charging stations around you see, you think ‘Alright, it might not be so hard to ensure that I don’t run out of power for my car.’ All of that stuff I think will start to pick up. But right now it is a little bit lagging in Atlantic Canada, and in Labrador infrastructure still lags despite a government push in N.L. to expand EVs.” 

'Simple dollars and cents'
The lack of a provincial government rebate here for electric vehicles definitely factors into the equation, said Sean O’Regan, president and chief executive officer of O'Regan's Automotive Group.  

“Where you see the highest adoption are in the provinces where there are large government rebates,” he said. “It’s a simple dollars and cents (thing). In Quebec, when you combine the rebates it’s up to over $10,000, if not $12,000, towards the car. If you can get that kind of a rebate on a car, I don’t know that it would matter much what it was – it would help sell it.” 

A lot of people who want to buy electric cars are trying to make a conscious decision about the environment, O’Regan said. 

While Nova Scotia Power is moving towards renewable energy, he points out that much of our electricity still comes from burning coal and other fossil fuels, and N.L. lags in energy efficiency as the region works to improve.  

“So the power that you get is not necessarily the cleanest of power,” O’Regan said. “The green advantage is not the same (in Nova Scotia as it is in provinces that produce a lot of hydro power).” 

Compared to five years ago, the charging infrastructure here is a lot better, he said. But it doesn’t compare well to provinces including Quebec and B.C., though Newfoundland recently completed its first fast-charging network for electric car owners. 

“Certainly (with) electric cars – we're selling more and more and more of them,” O'Regan said, noting the per centage would be in the single digits of his overall sales. “But you're starting from zero a few years ago.” 

The highest number of people looking at buying electric cars was in B.C., with 57 per cent of those looking at buying a car saying they’d go electric, and even in southern Alberta interest is growing; like Bob Dylan in 1965 at the Newport Folk Festival.  

“The trends move from west to east across Canada,” said Jeff Farwell, chief executive officer of the All EV Canada electric car store in Burnside.  

“I would use the example of the craft beer market. It started in B.C. about 15 years before it finally went crazy in Nova Scotia. And if you look at Vancouver right now there’s (electric vehicles) everywhere.” 

Expectations high
Farwell expects electric vehicle sales to take off faster in Atlantic Canada than the craft beer market. “A lot faster.” 

His company also sells used electric vehicles in Prince Edward Island and is making moves to set up in Moncton, N.B. 

He’s been talking to Nova Scotia’s Department of Energy and Mines about creating rebates here for new and used electric vehicles. 

 “I guess they’re interested, but nothing’s happened,” Farwell said.  

Electric vehicles require “a bit of a lifestyle change,” he said. 

“The misconception is it takes a lot longer to charge a vehicle if it’s electric and gas only takes me 10 minutes to fill up at the gas station,” Farwell said.  

“The reality is when I go home at night, I plug my vehicle in,” he said. “I get up in the morning and I unplug it and I never have to think about it. It takes two seconds.”

Waste-to-Graphene uses flash joule heating to convert carbon-rich trash into turbostratic graphene for composites, asphalt, concrete, and flexible electronics, delivering scalable, low-cost, high-quality material from food scraps, plastics, and tires with minimal processing.

Key Points

A flash heating method converting waste carbon into turbostratic graphene for scalable, low-cost industrial uses.

✅ Converts food scraps, plastics, and tires into graphene

✅ Produces turbostratic flakes that disperse well in composites

✅ Scalable, low-cost process via flash joule heating

Science doesn’t usually take after fairy tales. But Rumpelstiltskin, the magical imp who spun straw into gold, would be impressed with the latest chemical wizardry. Researchers at Rice University report today in Nature that they can zap virtually any source of solid carbon, from food scraps to old car tires, and turn it into graphene—sheets of carbon atoms prized for applications ranging from high-strength plastic to flexible electronics, and debates over 5G electricity use continue to evolve. Current techniques yield tiny quantities of picture-perfect graphene or up to tons of less prized graphene chunks; the new method already produces grams per day of near-pristine graphene in the lab, and researchers are now scaling it up to kilograms per day.

“This work is pioneering from a scientific and practical standpoint” as it promises to make graphene cheap enough to use to strengthen asphalt or paint, says Ray Baughman, a chemist at the University of Texas, Dallas. “I wish I had thought of it.” The researchers have already founded a new startup company, Universal Matter, to commercialize their waste-to-graphene process, while others are digitizing the electrical system to modernize infrastructure.

With atom-thin sheets of carbon atoms arranged like chicken wire, graphene is stronger than steel, conducts electricity and heat better than copper, and can serve as an impermeable barrier preventing metals from rusting, while advances such as superconducting cables aim to cut grid losses. But since its 2004 discovery, high-quality graphene—either single sheets or just a few stacked layers—has remained expensive to make and purify on an industrial scale. That’s not a problem for making diminutive devices such as high-speed transistors and efficient light-emitting diodes. But current techniques, which make graphene by depositing it from a vapor, are too costly for many high-volume applications. And higher throughput approaches, such as peeling graphene from chunks of the mineral graphite, produce flecks composed of up to 50 graphene layers that are not ideal for most applications.

Graphene comes in many forms. Single sheets, which are ideal for electronics and optics, can be grown using a method called chemical vapor deposition. But it produces only tiny amounts. For large volumes, companies commonly use a technique called liquid exfoliation. They start with chunks of graphite, which is just myriad stacked graphene layers. Then they use acids and solvents, as well as mechanical grinding, to shear off flakes. This approach typically produces tiny platelets each made up of 20 to 50 layers of graphene.

In 2014, James Tour, a chemist at Rice, and his colleagues found they could make a pure form of graphene—each piece just a few layers thick—by zapping a form of amorphous carbon called carbon black with a laser. Brief pulses heated the carbon to more than 3000 kelvins, snapping the bonds between carbon atoms; for comparison, researchers have also generated electricity from falling snow using triboelectric effects. As the cloud of carbon cooled, it coalesced into the most stable structure possible, graphene. But the approach still produced only tiny qualities and required a lot of energy.

Two years ago, Luong Xuan Duy, one of Tour’s graduate students, read that other researchers had created metal nanoparticles by zapping a material with electricity, creating the same brief blast of heat behind the success of the laser graphene approach. “I wondered if I could use that to heat a carbon source and produce graphene,” Duy says. So, he put a dash of carbon black in a clear glass vial and zapped it with 400 volts, similar in spirit to electrical weed zapping approaches in agriculture, for about 200 milliseconds. Initially he got junk. But after a bit of tweaking, he managed to create a bright yellowish white flash, indicating the temperature inside the vial was reaching about 3000 kelvins. Chemical tests revealed he had produced graphene.

It turned out to be a type of graphene that is ideal for bulk uses. As the carbon atoms condense to form graphene, they don’t have time to stack in a regular pattern, as they do in graphite. The result is a material known as turbostatic graphene, with graphene layers jumbled at all angles atop one another. “That’s a good thing,” Duy says. When added to water or other solvents, turbostatic graphene remains suspended instead of clumping up, allowing each fleck of the material to interact with whatever composite it’s added to.

“This will make it a very good material for applications,” says Monica Craciun, a materials physicist at the University of Exeter. In 2018, she and her colleagues reported that adding graphene to concrete more than doubled its compressive strength. Tour’s team saw much the same result. When they added just 0.05% by weight of their flash-produced graphene to concrete, the compressive strength rose 25%; graphene added to polydimethylsiloxane, a common plastic, boosted its strength by 250%.

As digital control spreads across energy networks, research to counter ransomware-driven blackouts is increasingly important for grid resilience.

Those results could reignite efforts to use graphene in a wide range of composites. Researchers in Italy reported recently that adding graphene to asphalt dramatically reduces its tendency to fracture and more than doubles its life span. Last year, Iterchimica, an Italian company, began to test a 250-meter stretch of road in Milan paved with graphene-spiked asphalt. Tests elsewhere have shown that adding graphene to paint dramatically improves corrosion resistance.

These applications would require high-quality graphene by the ton. Fortunately, the starting point for flash graphene could hardly be cheaper or more abundant: Virtually any organic matter, including coffee grounds, food scraps, old tires, and plastic bottles, can be vaporized to make the material. “We’re turning garbage into graphene,” Duy says.

IVECO BUS is making significant strides in the French public transportation sector, recently securing contracts for the delivery of hydrogen and battery electric buses. This development underscores the growing commitment of cities and regions in France to transition to cleaner, more sustainable public transportation options, even as electric bus adoption challenges persist. With these new contracts, IVECO BUS is poised to strengthen its position as a leader in the electric mobility market.

Expanding the Green Bus Fleet

The contracts involve the supply of various models of IVECO's hydrogen and electric buses, highlighting a strategic shift towards sustainable transport solutions. France has been proactive in its efforts to reduce carbon emissions and promote environmentally friendly transportation. As part of this initiative, many local authorities are investing in clean bus fleets, which has opened up substantial opportunities for manufacturers like IVECO.

These contracts will provide multiple French cities with advanced vehicles designed to minimize environmental impact while maintaining high performance and passenger comfort. The move towards hydrogen and battery electric buses reflects a broader trend in public transportation, where cities are increasingly adopting green technologies, with lessons from TTC's electric bus fleet informing best practices to meet both regulatory requirements and public demand for cleaner air.

The Role of Hydrogen and Battery Electric Technology

Hydrogen and battery electric buses represent two key technologies in the transition to sustainable transport. Battery electric buses are known for their zero tailpipe emissions, making them ideal for urban environments where air quality is a pressing concern, as demonstrated by the TTC battery-electric rollout in North America. IVECO's battery electric models come equipped with advanced features, including fast charging capabilities and longer ranges, making them suitable for various operational needs.

On the other hand, hydrogen buses offer the advantage of rapid refueling and extended range, addressing some of the limitations associated with battery electric vehicles, as seen with fuel cell buses in Mississauga deployments across transit networks. IVECO’s hydrogen buses utilize cutting-edge fuel cell technology, allowing them to operate efficiently in urban and intercity routes. This flexibility positions them as a viable solution for public transport authorities aiming to diversify their fleets.

Economic and Environmental Benefits

The adoption of hydrogen and battery electric buses is not only beneficial for the environment but also presents economic opportunities. By investing in these technologies, local governments can reduce operating costs associated with traditional diesel buses. Electric and hydrogen buses generally have lower fuel costs and require less maintenance, resulting in long-term savings.

Furthermore, the transition to cleaner buses can help stimulate local economies. As cities invest in electric mobility, new jobs will be created in manufacturing, maintenance, and infrastructure development, such as charging stations and hydrogen fueling networks, including the UK bus charging hub model, which supports large-scale operations. This shift can have a positive ripple effect, contributing to overall economic growth while fostering a cleaner environment.

IVECO BUS's Commitment to Sustainability

IVECO BUS's recent successes in France align with the company’s broader commitment to sustainability and innovation. As part of the CNH Industrial group, IVECO is dedicated to advancing green technologies and reducing the carbon footprint of public transportation. The company has been at the forefront of developing environmentally friendly vehicles, and these new contracts further reinforce its leadership position in the market.

Moreover, IVECO is investing in research and development to enhance the performance and efficiency of its electric and hydrogen buses. This commitment to innovation ensures that the company remains competitive in a rapidly evolving market while meeting the changing needs of public transport authorities.

Future Prospects

As more cities in France and across Europe commit to sustainable transportation, including initiatives like the Berlin zero-emission bus initiative, the demand for hydrogen and battery electric buses is expected to grow. IVECO BUS is well-positioned to capitalize on this trend, with a diverse range of products that cater to various operational requirements.

The successful implementation of these contracts will likely encourage other regions to follow suit, paving the way for a greener future in public transportation. As IVECO continues to innovate and expand its offerings, alongside developments like Volvo electric trucks in Europe, it sets a precedent for the industry, illustrating how commitment to sustainability can drive business success.

Canada Critical Infrastructure Cyber Risks include state-sponsored actors probing the electricity grid and ICS/OT, ransomware on utilities, and espionage targeting smart cities, medical devices, and energy networks, pre-positioning for disruptive operations.

Key Points

Nation-state and criminal cyber risks to Canada's power, water, and OT/ICS, aiming to disrupt, steal data, or extort.

✅ State-sponsored probing of power grid and utilities

✅ OT/ICS exposure grows as systems connect to IT networks

✅ Ransomware, espionage, and pre-positioning for disruption

State-sponsored actors are "very likely" trying to shore up their cyber capabilities to attack Canada's critical infrastructure — such as the electricity supply, as underscored by the IEA net-zero electricity report indicating rising demand for clean power, to intimidate or to prepare for future online assaults, a new intelligence assessment warns.

"As physical infrastructure and processes continue to be connected to the internet, cyber threat activity has followed, leading to increasing risk to the functioning of machinery and the safety of Canadians," says a new national cyber threat assessment drafted by the Communications Security Establishment.

"We judge that state-sponsored actors are very likely attempting to develop the additional cyber capabilities required to disrupt the supply of electricity in Canada, even as cleaning up Canada's electricity remains critical for climate goals."

Today's report — the second from the agency's Canadian Centre for Cyber Security wing — looks at the major cyber threats to Canadians' physical safety and economic security.

The CSE does say in the report that while it's unlikely cyber threat actors would intentionally disrupt critical infrastructure — such as water and electricity supplies — to cause major damage or loss of life, they would target critical organizations "to collect information, pre-position for future activities, or as a form of intimidation."

The report said Russia-associated actors probed the networks of electricity utilities in the U.S. and Canada last year and Chinese state-sponsored cyber threat actors have targeted U.S. utility employees. Other countries have seen their industrial control systems targeted by Iranian hacking groups and North Korean malware was found in the IT networks of an Indian power plant, it said.

The threat grows as more critical infrastructure goes high-tech.

In the past, the operational technology (OT) used to control dams, boilers, electricity and pipeline operations has been largely immune to cyberattacks — but that's changing as manufacturers incorporate newer information technology in their systems and products and as the race to net-zero drives grid modernization, says the report.

That technology might make things easier and lower costs for utilities already facing debates over electricity prices in Alberta amid affordability concerns, but it comes with risks, said Scott Jones, the head of the cyber centre.

"So that means now it is a target, it is accessible and it's vulnerable. So what you could see is shutting off of transmission lines, you can see them opening circuit breakers, meaning electricity simply won't flow to our homes to our business," he told reporters Wednesday.

While the probability of such attacks remains low, Jones said the goal of Wednesday's briefing is to send out the early warnings.

"We're not trying to scare people. We're certainly not trying to scare people into going off grid by building a cabin in the woods. We're here to say, 'Let's tackle these now while they're still paper, while they're still a threat we're writing down.'"

Steve Waterhouse, a former cybersecurity officer for the Department of National Defence who now teaches at Université de Sherbrooke, said a saving grace for Canada could be the makeup of its electrical systems.

"Since in Canada, they're very centralized, it's easier to defend, and debates about bridging Alberta and B.C. electricity aim to strengthen resilience, while down in the States, they have multiple companies all around the place. So the weakest link is very hard to identify where it is, but the effect is a cascading effect across the country ... And it could impact Canada, just like we saw in the big Northeastern power outage, the blackout of 2003," he said.

"So that goes to say, we have to be prepared. And I believe most energy companies have been taking extra measures to protect and defend against these type of attacks, even as Canada points to nationwide climate success in electricity to meet emissions goals."

In the future, attacks targeting so-called smart cities and internet-connected devices, such as personal medical devices, could also put Canadians at risk, says the report. 

Earlier this year, for example, Health Canada warned the public that medical devices containing a particular Bluetooth chip — including pacemakers, blood glucose monitors and insulin pumps — are vulnerable to cyber attacks that could crash them.

The foreign signals intelligence agency also says that while state-sponsored programs in China, Russia, Iran and North Korea "almost certainly" pose the greatest state-sponsored cyber threats to Canadian individuals and organizations, many other states are rapidly developing their own cyber programs.

Waterhouse said he was glad to see the government agency call out the countries by name, representing a shift in approach in recent years.

"To tackle on and be ready to face a cyber-attack, you have to know your enemy," he said.

"You have to know what's vulnerable inside of your organization. You have to know how ... vulnerable it is against the threats that are out there."

Commercial espionage continues
State-sponsored actors will also continue their commercial espionage campaigns against Canadian businesses, academia and governments — even as calls to make Canada a post-COVID manufacturing hub grow — to steal Canadian intellectual property and proprietary information, says the CSE.

"We assess that these threat actors will almost certainly continue attempting to steal intellectual property related to combating COVID-19 to support their own domestic public health responses or to profit from its illegal reproduction by their own firms," says the "key judgments" section of the report.

"The threat of cyber espionage is almost certainly higher for Canadian organizations that operate abroad or work directly with foreign state-owned enterprises."

The CSE says such commercial espionage is happening already across multiple fields, including aviation, technology and AI, energy and biopharmaceuticals.

While state-sponsored cyber activity tends to offer the most sophisticated threats, CSE said that cybercrime continues to be the threat most likely to directly affect Canadians and Canadian organizations, through vectors like online scams and malware.

"We judge that ransomware directed against Canada will almost certainly continue to target large enterprises and critical infrastructure providers. These entities cannot tolerate sustained disruptions and are willing to pay up to millions of dollars to quickly restore their operations," says the report.

Cybercrime becoming more sophisticated 
According to the Canadian Anti-Fraud Centre, Canadians lost over $43 million to cybercrime last year. The CSE reported earlier this year that online thieves have been using the COVID-19 pandemic to trick Canadians into forking over their money — through scams like a phishing campaign that claimed to offer access to a Canada Emergency Response Benefit payment in exchange for the target's personal financial details.

Online foreign influence activities — a dominant theme in the CSE's last threat assessment briefing — continue and constitute "a new normal" in international affairs as adversaries seek to influence domestic and international political events, says the agency.

"We assess that, relative to some other countries, Canadians are lower-priority targets for online foreign influence activity," it said.

"However, Canada's media ecosystem is closely intertwined with that of the United States and other allies, which means that when their populations are targeted, Canadians become exposed to online influence as a type of collateral damage."

According to the agency's own definition, "almost certainly" means it is nearly 100 per cent certain in its analysis, while "very likely" means it is 80-90 per cent certain of its conclusions. The CSE says its analysis is based off of a mix of confidential and non-confidential intelligence and sources.

Fukushima Daiichi decommissioning delay highlights TEPCO's revised timeline, spent fuel removal at Units 1 and 2, safety enclosures, decontamination, fuel debris extraction by robot arm, and contaminated water management under stricter radiation control.

Key Points

A government revised schedule pushing back spent fuel removal and decommissioning milestones at Fukushima Daiichi.

✅ TEPCO delays spent fuel removal at Units 1 and 2 for safety.

✅ Enclosures, decontamination, and robotics mitigate radioactive risk.

✅ Contaminated water cut target: 170 tons/day to 100 by 2025.

The Japanese government decided Friday to delay the removal of spent fuel from the Fukushima Daiichi nuclear power plant's Nos. 1 and 2 reactors by as much as five years, casting doubt on whether it can stick to its timeframe for dismantling the crippled complex.

The process of removing the spent fuel from the units' pools had previously been scheduled to begin in the year through March 2024.

In its latest decommissioning plan, the government said the plant's operator, Tokyo Electric Power Company Holdings Inc., will not begin the roughly two-year process (a timeline comparable to major reactor refurbishment programs seen worldwide) at the No. 1 unit at least until the year through March 2028 and may wait until the year through March 2029.

Work at the No. 2 unit is now slated to start between the year through March 2025 and the year through March 2027, it said.

The delay is necessary to take further safety precautions such as the construction of an enclosure around the No. 1 unit to prevent the spread of radioactive dust, and decontamination of the No. 2 unit, even as authorities have begun reopening previously off-limits towns nearby, the government said. It is the fourth time it has revised its schedule for removing the spent fuel rods.

"It's a very difficult process and it's hard to know what to expect. The most important thing is the safety of the workers and the surrounding area," industry minister Hiroshi Kajiyama told a press conference.

The government set a new goal of finishing the removal of the 4,741 spent fuel rods across all six of the plant's reactors by the year through March 2032, amid ongoing debates about the consequences of early nuclear plant closures elsewhere.

Plant operator TEPCO has started the process at the No. 3 unit and already finished at the No. 4 unit, which was off-line for regular maintenance at the time of the disaster. A schedule has yet to be set for the Nos. 5 and 6 reactors.

While the government maintained its overarching timeframe of finishing the decommissioning of the plant 30 to 40 years from the 2011 crisis triggered by a magnitude 9.0 earthquake and tsunami, there may be further delays, even as milestones at other nuclear projects are being reached worldwide.

The government said it will begin removing fuel debris from the three reactors that experienced core meltdowns in the year through March 2022, starting with the No. 2 unit as part of broader reactor decommissioning efforts.

The process, considered the most difficult part of the decommissioning plan, will involve using a robot arm, reflecting progress in advanced reactors technologies, to initially remove small amounts of debris, moving up to larger amounts.

The government also said it will aim to reduce the pace at which contaminated water at the plant increases. Water for cooling the melted cores, mixed with underground water, amounts to around 170 tons a day. That number will be brought down to 100 tons by 2025, it said.

The water is being treated to remove the most radioactive materials and stored in tanks on the plant's grounds, but already more than 1 million tons has been collected and space is expected to run out by the summer of 2022.
