A hydro vault fire has left many homes in the Yonge St. and Eglinton Ave. E. area without power.

Police say the vault burst into flames at around 5:40 a.m., near a cluster of apartment buildings on Erskine Ave., west of Mt. Pleasant Rd.

Fire crews quickly extinguished the blaze, but power was out in the area until late in the morning.

The affected area runs north of Eglinton Ave. to Alexandra Blvd, and just west of Yonge St. to about Mt. Pleasant Rd.

“Hydro is aware of it and they’re working overtime to rectify it,” said Toronto police Const. Marc Kalteis.

No injuries were reported but a few thousand people have been affected by the outage.

A set of downed power lines near Chaplin Cres. and Eglinton Ave. W. could also be contributing to the problem, according to Toronto Hydro.

The Chaplin-area outage began at around 5:30 a.m. and is affecting roughly 265 people. That area is bordered by Forest Hill Rd. and Spadina Rd. on the east, and running southeast along Dunvegan Rd. until about Frybrook Rd.

Investigators are currently looking into the cause of the outages, a process that may take several days.

Carbon capture: How can we remove CO2 from the atmosphere?

CO2 Removal Technologies address climate change via negative emissions, including carbon capture, reforestation, soil carbon, biochar, BECCS, DAC, and mineralization, helping meet Paris Agreement targets while managing costs, land use, and infrastructure demands.

 

Key Points

Methods to extract or sequester atmospheric CO2, combining natural and engineered approaches to limit warming.

✅ Includes reforestation, soil carbon, biochar, BECCS, DAC, mineralization

✅ Balances climate goals with costs, land, energy, and infrastructure

✅ Key to Paris Agreement targets under 1.5-2.0 °C warming

 

The world is, on average, 1.1 degrees Celsius warmer today than it was in 1850. If this trend continues, our planet will be 2 – 3 degrees hotter by the end of this century, according to the Intergovernmental Panel on Climate Change (IPCC).

The main reason for this temperature rise is higher levels of atmospheric carbon dioxide, which cause the atmosphere to trap heat radiating from the Earth into space. Since 1850, the proportion of CO2 in the air has increased, with record greenhouse gas concentrations documented, from 0.029% to 0.041% (288 ppm to 414 ppm).

This is directly related to the burning of coal, oil and gas, which were created from forests, plankton and plants over millions of years. Back then, they stored CO2 and kept it out of the atmosphere, but as fossil fuels are burned, that CO2 is released. Other contributing factors include industrialized agriculture and slash-and-burn land clearing techniques, and emissions from SF6 in electrical equipment are also concerning today.

Over the past 50 years, more than 1200 billion tons of CO2 have been emitted into the planet's atmosphere — 36.6 billion tons in 2018 alone, though global emissions flatlined in 2019 before rising again. As a result, the global average temperature has risen by 0.8 degrees in just half a century.


Atmospheric CO2 should remain at a minimum
In 2015, the world came together to sign the Paris Climate Agreement which set the goal of limiting global temperature rise to well below 2 degrees — 1.5 degrees, if possible.

The agreement limits the amount of CO2 that can be released into the atmosphere, providing a benchmark for the global energy transition now underway. According to the IPCC, if a maximum of around 300 billion tons were emitted, there would be a 50% chance of limiting global temperature rise to 1.5 degrees. If CO2 emissions remain the same, however, the CO2 'budget' would be used up in just seven years.

According to the IPCC's report on the 1.5 degree target, negative emissions are also necessary to achieve the climate targets.


Using reforestation to remove CO2
One planned measure to stop too much CO2 from being released into the atmosphere is reforestation. According to studies, 3.6 billion tons of CO2 — around 10% of current CO2 emissions — could be saved every year during the growth phase. However, a study by researchers at the Swiss Federal Institute of Technology, ETH Zurich, stresses that achieving this would require the use of land areas equivalent in size to the entire US.

Reforestation has potential to tackle the climate crisis by capturing CO2. But it would require a large amount of space


More humus in the soil
Humus in the soil stores a lot of carbon. But this is being released through the industrialization of agriculture. The amount of humus in the soil can be increased by using catch crops and plants with deep roots as well as by working harvest remnants back into the ground and avoiding deep plowing. According to a study by the German Institute for International and Security Affairs (SWP) on using targeted CO2 extraction as a part of EU climate policy, between two and five billion tons of CO2 could be saved with a global build-up of humus reserves.


Biochar shows promise
Some scientists see biochar as a promising technology for keeping CO2 out of the atmosphere. Biochar is created when organic material is heated and pressurized in a zero or very low-oxygen environment. In powdered form, the biochar is then spread on arable land where it acts as a fertilizer. This also increases the amount of carbon content in the soil. According to the same study from the SWP, global application of this technology could save between 0.5 and two billion tons of CO2 every year.


Storing CO2 in the ground
Storing CO2 deep in the Earth is already well-known and practiced on Norway's oil fields, for example. However, the process is still controversial, as storing CO2 underground can lead to earthquakes and leakage in the long-term. A different method is currently being practiced in Iceland, in which CO2 is sequestered into porous basalt rock to be mineralized into stone. Both methods still require more research, however, with new DOE funding supporting carbon capture, utilization, and storage.

Capturing CO2 to be held underground is done by using chemical processes which effectively extract the gas from the ambient air, and some researchers are exploring CO2-to-electricity concepts for utilization. This method is known as direct air capture (DAC) and is already practiced in other parts of Europe.  As there is no limit to the amount of CO2 that can be captured, it is considered to have great potential. However, the main disadvantage is the cost — currently around €550 ($650) per ton. Some scientists believe that mass production of DAC systems could bring prices down to €50 per ton by 2050. It is already considered a key technology for future climate protection.

Carbon capture facilities are still very expensive and take up a huge amount of space

Another way of extracting CO2 from the air is via biomass. Plants grow and are burned in a power plant to produce electricity. CO2 is then extracted from the exhaust gas of the power plant and stored deep in the Earth, with new U.S. power plant rules poised to test such carbon capture approaches.

The big problem with this technology, known as bio-energy carbon capture and storage (BECCS) is the huge amount of space required. According to Felix Creutzig from the Mercator Institute on Global Commons and Climate Change (MCC) in Berlin, it will therefore only play "a minor role" in CO2 removal technologies.


CO2 bound by rock minerals
In this process, carbonate and silicate rocks are mined, ground and scattered on agricultural land or on the surface water of the ocean, where they collect CO2 over a period of years. According to researchers, by the middle of this century it would be possible to capture two to four billion tons of CO2 every year using this technique. The main challenges are primarily the quantities of stone required, and building the necessary infrastructure. Concrete plans have not yet been researched.


Not an option: Fertilizing the sea with iron
The idea is use iron to fertilize the ocean, thereby increasing its nuturient content, which would allow plankton to grow stronger and capture more CO2. However, both the process and possible side effects are very controversial. "This is rarely treated as a serious option in research," concludes SWP study authors Oliver Geden and Felix Schenuit.

Fire in manhole leaves thousands of Hydro-Québec customers without power

Montreal Power Outage linked to Hydro-Que9bec infrastructure after an underground explosion and manhole fire in Rosemont–La Petite–Patrie, disrupting the STM Blue Line and forcing strategic, cold-weather grid restoration on Be9langer Street.

 

Key Points

Outage from an underground blast and manhole fire disrupted STM service; Hydro-Que9bec restored the grid in cold weather.

✅ Peak impact: 41,000 customers; 10,981 still without power by 7:00 p.m.

✅ STM Blue Line restored after afternoon shutdown; Be9langer Street reopened.

✅ Hydro-Que9bec pacing restoration to avoid grid overload in cold weather.

 

Hydro-Québec says a power outage affecting Montreal is connected to an underground explosion and a fire in a manhole in Rosemont—La Petite–Patrie. 

The fire started in underground pipes belonging to Hydro-Québec on Bélanger Street between Boyer and Saint-André streets, according to Montreal firefighters, who arrived on the scene at 12:18 p.m.

The electricity had to be cut so that firefighters could get into the manhole where the equipment was located.

At the peak of the shutdown, nearly 41,000 customers were without power across Montreal.  As of 7:00 p.m., 10,981 clients still had no power.

In similar storms, Toronto power outages have persisted for hundreds, underscoring restoration challenges.

Hydro-Québec spokesperson Louis-Olivier Batty said the utility is being strategic about how it restores power across the grid. 

Because of the cold, and patterns seen during freezing rain outages, it anticipates that people will crank up the heat as soon as they get their electricity back, and that could trigger an overload somewhere else on the network, Batty said.

The Metro's Blue line was down much of the afternoon, but the STM announced the line was back up and running just after 4:30 p.m.

Bélanger Street was blocked to traffic much of the afternoon, however, it has now been reopened.

Batty said once the smoke clears, Hydro-Québec workers will take a look at the equipment to see what failed.

State-sponsored actors 'very likely' looking to attack electricity supply, says intelligence agency

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.

Opinion: Nuclear Beyond Electricity

Nuclear decarbonization leverages low-carbon electricity, process heat, and hydrogen from advanced reactors and SMRs to electrify industry, buildings, and transport, supporting net-zero strategies and grid flexibility alongside renewables with dispatchable baseload capacity.

 

Key Points

Nuclear decarbonization uses reactors to supply low-carbon power, heat, and hydrogen, cutting emissions across industry.

✅ Advanced reactors and SMRs enable high-temperature process heat

✅ Nuclear-powered electrolysis and HTSE produce low-carbon hydrogen

✅ District heating from reactors reduces pollution and coal use

 

By Dr Henri Paillere, Head of the Planning and Economics Studies Section of the IAEA

Decarbonising the power sector will not be sufficient to achieving net-zero emissions, with assessments indicating nuclear may be essential across sectors. We also need to decarbonise the non-power sectors - transport, buildings and industry - which represent 60% of emissions from the energy sector today. The way to do that is: electrification with low-carbon electricity as much as possible; using low-carbon heat sources; and using low-carbon fuels, including hydrogen, produced from clean electricity.
The International Energy Agency (IEA) says that: 'Almost half of the emissions reductions needed to reach net zero by 2050 will need to come from technologies that have not reached the market today.' So there is a need to innovate and push the research, development and deployment of technologies. That includes nuclear beyond electricity.

Today, most of the scenario projections see nuclear's role ONLY in the power sector, despite ongoing debates over whether nuclear power is in decline globally, but increased electrification will require more low-carbon electricity, so potentially more nuclear. Nuclear energy is also a source of low-carbon heat, and could also be used to produce low-carbon fuels such as hydrogen. This is a virtually untapped potential.

There is an opportunity for the nuclear energy sector - from advanced reactors, next-gen nuclear small modular reactors, and non-power applications - but it requires a level playing field, not only in terms of financing today's technologies, but also in terms of promoting innovation and supporting research up to market deployment. And of course technology readiness and economics will be key to their success.

On process heat and district heating, I would draw attention to the fact there have been decades of experience in nuclear district heating. Not well spread, but experience nonetheless, in Russia, Hungary and Switzerland. Last year, we had two new projects. One floating nuclear power plant in Russia (Akademik Lomonosov), which provides not only electricity but district heating to the region of Pevek where it is connected. And in China, the Haiyang nuclear power plant (AP1000 technology) has started delivering commercial district heating. In China, there is an additional motivation to reducing emissions, namely to cut air pollution because in northern China a lot of the heating in winter is provided by coal-fired boilers. By going nuclear with district heating they are therefore cutting down on this pollution and helping with reducing carbon emissions as well. And Poland is looking at high-temperature reactors to replace its fleet of coal-fired boilers and so that's a technology that could also be a game-changer on the industry side.

There have also been decades of research into the production of hydrogen using nuclear energy, but no real deployment. Now, from a climate point of view, there is a clear drive to find substitute fuels for the hydrocarbon fuels that we use today, and multiple new nuclear stations are seen by industry leaders as necessary to meet net-zero targets. In the near term, we will be able to produce hydrogen with electrolysis using low-carbon electricity, from renewables and nuclear. But the cheapest source of low-carbon power is from the long-term operation of existing nuclear power plants which, combined with their high capacity factors, can give the cheapest low-carbon hydrogen of all.

In the mid to long term, there is research on-going with processes that are more efficient than low-temperature electrolysis, which is high temperature steam electrolysis or thermal splitting of water. These may offer higher efficiencies and effectiveness but they also require advanced reactors that are still under development. Demonstration projects are being considered in several countries and we at the IAEA are developing a publication that looks into the business opportunities for nuclear production of hydrogen from existing reactors. In some countries, there is a need to boost the economics of the existing fleet, especially in the electricity systems where you have low or even negative market prices for electricity. So, we are looking at other products that have higher values to improve the competitiveness of existing nuclear power plants.

The future means not only looking at electricity, but also at industry and transport, and so integrated energy systems. Electricity will be the main workhorse of our global decarbonisation effort, but through heat and hydrogen. How you model this is the object of a lot of research work being done by different institutes and we at the IAEA are developing some modelling capabilities with the objective of optimising low-carbon emissions and overall costs.

This is just a picture of what the future might look like: a low-carbon power system with nuclear lightwater reactors (large reactors, small modular reactors and fast reactors) drawing on the green industrial revolution reactor waves in planning; solar, wind, anything that produces low-carbon electricity that can be used to electrify industry, transport, and the heating and cooling of buildings. But we know there is a need for high-temperature process steam that electricity cannot bring but which can be delivered directly by high-temperature reactors. And there are a number of ways of producing low-carbon hydrogen. The beauty of hydrogen is that it can be stored and it could possibly be injected into gas networks that could be run in the future on 100% hydrogen, and this could be converted back into electricity.

So, for decarbonising power, there are many options - nuclear, hydro, variable renewables, with renewables poised to surpass coal in global generation, and fossil with carbon capture and storage - and it's up to countries and industries to invest in the ones they prefer. We find that nuclear can actually reduce the overall cost of systems due to its dispatchability and the fact that variable renewables have a cost because of their intermittency. There is a need for appropriate market designs and the role of governments to encourage investments in nuclear.

Decarbonising other sectors will be as important as decarbonising electricity, from ways to produce low-carbon heat and low-carbon hydrogen. It's not so obvious who will be the clear winners, but I would say that since nuclear can produce all three low-carbon vectors - electricity, heat and hydrogen - it should have the advantage.
We at the IAEA will be organising a webinar next month with the IEA looking at long-term nuclear projections in a net-zero world, building on IAEA analysis on COVID-19 and low-carbon electricity insights. That will be our contribution from the point of view of nuclear to the IEA's special report on roadmaps to net zero that it will publish in May.

UK Emergency energy plan not going ahead

National Grid Demand Flexibility Service helps stabilise the UK grid during tight supply, offering discounts for smart meter users who shift peak-time electricity use, reducing power cut risks amid low wind and import constraints.

 

Key Points

A National Grid scheme paying smart homes to cut peak-time use, easing supply pressure and avoiding power cuts.

✅ Pays volunteers with smart meters to reduce peak demand.

✅ Credits discounts for shifting use to off-peak windows.

✅ Manages tight margins and helps avert UK power cuts.

 

National Grid has decided not to activate a scheme on Tuesday to help the UK avoid power cuts after being poised to do so.

It would have seen some households offered discounts on their electricity bills if they cut peak-time use.

National Grid had been ready to trigger the scheme following a warning that Britain's energy supplies were looking tighter than usual this week.

However, it decided that the measure was not required.

Alerts are sent out automatically when expected supplies drop below a certain level. But they do not mean that blackouts are likely, or that the situation is critical.

National Grid said it was "confident" it would be able to manage margins and "demand is not at risk".

Discounts
Earlier on Monday, the grid operator said it was considering whether to pay households across Britain to reduce their energy use to help out on Tuesday evening.

Under the Demand Flexibility Service (DFS), announced earlier this month, customers that have signed up could get discounts on their bills if they use less electricity in a given window of time.

That could mean delaying the use of a tumble-dryer or washing machine, or cooking dinner in the microwave rather than the oven.

Major suppliers such as Octopus and British Gas are taking part, but only customers that have an electricity smart meter and that have volunteered are eligible. About 14 million UK homes have an electricity smart meter.

The DFS has already been tested twice but has not yet run live.

Octopus, the supplier with the most customers signed up, said that some households had earned more than £4 during the hour-long tests, while the average saving was "well over £1".

It came after forecasts projected a large drop in the amount of power that Britain will be able to import from French nuclear power stations on Monday and Tuesday evenings.

The lack of strong winds to power turbines has also affected how much power can be generated within the UK, and efforts to fast-track grid connections aim to ease constraints.

Such warnings are not unusual - around 12 have been issued and cancelled without issue in the last six years, and other regions such as Canada are seeing grids strained by harsh weather as well.

However, they have become more common this year due to the energy crisis, and the most recent notice was sent out last week.

The situation means that the UK will have to import electricity from other sources on Monday and Tuesday evening.

Supplies are also expected be tight in France, forecasters say.

France has been facing months of problems with its nuclear power plants, which generate around three-quarters of the country's electricity.

More than half of the nuclear reactors run by state energy company EDF have closed due to maintenance problems and technical issues.

It has added to a massive energy crisis in Europe which is facing a winter without gas supplies from Russia.
