Pickering nuclear refurbishment will modernize Ontario's Candu reactors at Pickering B, sustaining 2,000 MW of clean electricity, aiding net-zero goals, and aligning with Ontario Power Generation plans and Canadian Nuclear Safety Commission reviews.

Key Points

An 11-year overhaul of Pickering B Candu reactors to extend life, keep 2,000 MW online, and back Ontario net-zero grid.

✅ 11-year project; 11,000 annual jobs; $19.4B GDP impact.

✅ Refurbishes four Pickering B Candu units; maintains 2,000 MW.

✅ Requires Canadian Nuclear Safety Commission license approvals.

The Ontario government has announced its intention to pursue a Pickering refurbishment at the venerable nuclear power station, which has been operational for over fifty years. This move could extend the facility's life by another 30 years.

This decision is timely, as Ontario anticipates a significant surge in electricity demand and a growing electricity supply gap in the forthcoming years. Additionally, all provinces are grappling with new federal mandates for clean electricity, necessitating future power plants to achieve net-zero carbon emissions.

Todd Smith, the Energy Minister, is expected to endorse Ontario Power Generation's proposal for the plant's overhaul, as per a preliminary version of a government press release.

The renovation will focus on four Candu reactors, known collectively as Pickering B, which were originally commissioned in the early 1980s. This upgrade is projected to continue delivering 2,000 megawatts of power, equivalent to the current output of these units.

According to the press release, the project will span 11 years, create approximately 11,000 annual jobs, and contribute $19.4 billion to Ontario's GDP. However, the total budget for the project remains unspecified.

The project follows the ongoing refurbishment of four units at the nearby Darlington nuclear station, which is more than halfway completed with a budget of $12.8 billion.

The proposal awaits the Canadian Nuclear Safety Commission's approval, and officials face extension request timing considerations before key deadlines.

The Commission is also reviewing a prior request from OPG to extend the operational license of the existing Pickering B units until 2026. This extension would allow the plant to safely continue operating until the commencement of its renovation, pending approval.

Ontario's Ambitious Nuclear Strategy

The announcement regarding Pickering is part of Ontario's broader clean energy plan for an unprecedented expansion of nuclear power in Canada.

Last summer, the province announced its intention to nearly double the output at Bruce Power, currently the world's largest nuclear generating station.

Additionally, Ontario revealed SMR plans to construct three more alongside the existing project at Darlington. These reactors are expected to supply enough electricity to power around 1.2 million homes.

Discussions about revitalizing the Pickering facility began in 2022, after the station had been slated to close as planned amid debate, with Ontario Power Generation submitting a feasibility report to the government last summer.

The Ford government emphasized the necessity of this nuclear expansion to meet the increasing electricity demands anticipated from the auto sector's shift to electric vehicles, the steel industry's move away from coal-fired furnaces, and the growing population in Ontario.

Ontario's capability to attract major international car manufacturers like Volkswagen and Stellantis to produce electric vehicles and batteries is partly attributed to the fact that 90% of the province's electricity comes from non-fossil fuel sources.

Energy Vault Gravity Storage uses crane-stacked concrete blocks to deliver long-duration, grid-scale renewable energy; a SoftBank Vision Fund-backed, pumped-hydro analog enabling baseload power and a lithium-ion alternative with proprietary control algorithms.

Key Points

Gravity-based cranes stack blocks to store and dispatch power for hours, enabling grid-scale, low-cost storage.

✅ 4 MW/35 MWh modules; ~9-hour duration

✅ Estimated $200-$250/kWh; lower LCOE than lithium-ion

✅ Backed by SoftBank Vision Fund; Cemex and Tata support

Energy Vault, the Swiss-U.S. startup that says it can store and discharge electrical energy through a super-sized concrete-and-steel version of a child’s erector set, has landed a $110 million investment from Japan’s SoftBank Vision Fund to take its technology to commercial scale.

Energy Vault, a spinout of Pasadena-based incubator Idealab and co-founded by Idealab CEO and billionaire investor Bill Gross, unstealthed in November with its novel approach to using gravity to store energy.

Simply put, Energy Vault plans to build storage plants — dubbed “Evies” — consisting of a 35-story crane with six arms, surrounded by a tower consisting of thousands of concrete bricks, each weighing about 35 tons.

This plant will “store” energy by using electricity to run the cranes that lift bricks from the ground and stack them atop of the tower, and “discharge” energy by reversing that process. It’s a mechanical twist on the world’s most common energy storage technology, pumped hydro, which “stores” energy by pumping water uphill, and lets it fall to spin turbines when electricity is needed, even as California funds 100-hour long-duration storage pilots to expand flexibility worldwide.

But behind this simplicity lies some heavy-duty software to orchestrate the cranes and blocks, with a "unique stack of proprietary algorithms" to balance energy supply and demand, volatility, grid stability, weather elements and other variables.

CEO and co-founder Robert Piconi said in a November interview with GTM that the standard array would deliver 4 megawatts/35 megawatt-hours of storage, which translates to nearly 9 hours of duration — the equivalent of building the tower to its height, and then reducing it to ground level. It can be built on-site in partnership with crane manufacturers and recycled concrete material, and can run fully automated for decades with little deterioration, he said.

And the cost, which Piconi pegged in the $200 to $250 per kilowatt-hour range, with room to decline further, is roughly 50 percent below the upfront price of the conventional storage market today, and 80 percent below it on levelized cost, he said, a trend utilities see benefits in as they plan resources.

The result, according to Wednesday’s statement, is a technology that could allow “renewables to deliver baseload power for less than the cost of fossil fuels 24 hours a day,” in applications such as community microgrids serving low-income housing.

Wednesday’s announcement builds on a recent investment from Mexico's Cemex Ventures, the corporate venture capital unit of building materials giant Cemex, along with a promise of deployment support from Cemex's strategic network, and also follows project financing for a California green hydrogen microgrid led by the company. Piconi said in November that the company had sufficient investment from two funding rounds to carry it through initial customer deployments, though he declined to disclose figures.

This is the first energy storage investment for Vision Fund, the $100 billion venture fund set up by SoftBank founder Masayoshi Son. While large by startup standards, it’s in keeping with the capital costs that Energy Vault will face in scaling up its technology to meet its commitments, amid mounting demand in regions like Ontario energy storage that face supply crunches. Those include a 35 megawatt-hour order with Tata Power Company, the energy-producing arm of the Indian industrial conglomerate, first unveiled in November, as well as plans to demonstrate its first storage tower in northern Italy in 2019.

For Vision Fund, it’s also an unusual choice for a storage investment, given that the vast majority of venture capital in the industry today is being directed toward lithium-ion batteries, and even Mercedes-Benz energy storage ventures targeting the U.S. market. Lithium-ion batteries are limited in terms of how many hours they can provide cost-effectively, with about 4 hours being seen as the limit today.

The search for long-duration energy storage has driven investment into flow battery technologies such as grid-scale vanadium systems deployed on utility networks, compressed-air energy storage and variations on gravity-based storage, including a previous startup backed by Gross and Idealab, Energy Cache, whose idea of using a ski lift carrying buckets of gravel up a hill to store energy petered out with a 50-kilowatt pilot project.

Carbon Nanotube Solvent Electricity enables wire-free electrochemistry as organic solvents like acetonitrile pull electrons, powering alcohol oxidation and packed bed reactors, energy harvesting, and micro- and nanoscale robots via redox-driven current.

Key Points

Solvent-driven electron extraction from carbon nanotube particles generates current for electrochemistry.

✅ 0.7 V per particle via solvent-induced electron flow

✅ Packed bed reactors drive alcohol oxidation without wires

✅ Scalable for micro- and nanoscale robots; energy harvesting

MIT engineers have discovered a new way of generating electricity, alongside advances in renewable power at night that broaden what's possible, using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an organic solvent, draws electrons out of the particles, generating a current, unlike devices based on a cheap thermoelectric material that rely on heat, that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.

"This mechanism is new, and this way of generating energy is completely new," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. "This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires."

In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation—an organic chemical reaction that is important in the chemical industry.

Strano is the senior author of the paper, which appears today in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.

Unique properties
The new discovery grew out of Strano's research on carbon nanotubes—hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate "thermopower waves." When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current that exemplifies turning thermal energy into electricity in nanoscale systems.

That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry, distinct from conventional thermoelectric materials approaches, that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.

To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.

When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.

"The solvent takes electrons away, and the system tries to equilibrate by moving electrons," Strano says. "There's no sophisticated battery chemistry inside. It's just a particle and you put it into solvent and it starts generating an electric field."

Particle power
The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This "packed bed" reactor, unlike thin-film waste-heat harvesters for electronics, generates enough energy to power a chemical reaction called an alcohol oxidation, in which an alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.

"Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor," Zhang says. "The particles can be made very small, and they don't require any external wires in order to drive the electrochemical reaction."

In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy and informed by devices that generate electricity at night as a complement. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.

In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano's lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment, including approaches that produce electricity 'out of thin air' in ambient conditions, to power these kinds of robots is appealing, he says.

"It means you don't have to put the energy storage on board," he says. "What we like about this mechanism is that you can take the energy, at least in part, from the environment."

France Nuclear Heatwave Output Restrictions signal reduced reactor capacity along the Rhone River, as EDF curbs output to meet cooling-water rules, balance the grid, integrate solar peaks, and limit impacts on power prices.

Key Points

EDF limits reactor output during heat to protect rivers and keep the grid stable under cooling-water rules.

✅ Cuts likely at midday/weekends when solar peaks

✅ Bugey, Saint Alban maintain minimum grid output

✅ France net exporter; price impact expected small

The high temperature warning has come early this year but will affect fewer nuclear power plants, amid a broader France-Germany nuclear dispute over atomic power policy that shapes regional energy flows.

High temperatures could halve nuclear power production at plants along France's Rhone River this week, as European power hits records during extreme heat. 

Output restrictions are expected at two nuclear plants in eastern France due to high temperature forecasts, nuclear operator EDF said, which may limit energy output during heatwaves. It comes several days ahead of a similar warning that was made last year but will affect fewer plants.

The hot weather is likely to halve the available power supply from the 3.6 GW Bugey plant from 13 July and the 2.6 GW Saint Alban plant from 16 July, the operator said.

However, production will be at least 1.8 GW at Bugey and 1.3 GW at Saint Alban to meet grid requirements, and may change according to grid needs, the operator said.

Kpler analyst Emeric de Vigan said the restrictions were likely to have little effect on output in practice. Cuts are likely only at the weekend or midday when solar output was at its peak so the impact on power prices would be slim.

During recent lockdowns, power demand held firm in Europe, offering context for current price dynamics.

He said the situation would need monitoring in the coming weeks, however, noting it was unusually early in the summer for such restrictions to be imposed.

Water temperatures at the Bugey plant already eclipsed the initial threshold for restrictions on 9 July, underscoring France's outage risks under heat-driven constraints. They are currently forecast to peak next week and then drop again, Refinitiv data showed.

"France is currently net exporting large amounts of power – single nuclear units' supply restrictions will not have the same effect as last year," Refinitiv analyst Nathalie Gerl said.

The Garonne River in southern France has the highest potential for critical levels of warming, but its Golfech plant is currently offline for maintenance until mid-August, the data showed, highlighting how Europe is losing nuclear power during critical periods.

"(The restrictions were) to be expected and it will probably occur more often," Greenpeace campaigner Roger Spautz said.

"The authorities must stick to existing regulations for water discharges. Otherwise, the ecosystems will be even more affected," he added.

Electric weed-zapping farm robots enable precision agriculture, using autonomous mapping, per-plant targeting, and robotics to reduce pesticides, improve soil health, boost biodiversity, and lower costs with data-driven, selective weeding and seed-planting workflows.

Key Points

Autonomous machines that map fields, electrocute weeds per plant, and plant seeds, cutting pesticides, inputs, and costs.

✅ Precision agriculture: per-plant targeting reduces pesticide use up to 95%.

✅ Autonomous mapping robot surveys 20 hectares per day for weed data.

✅ Electric weeding and seeding improve soil health, biodiversity, and ROI.

On a field in England, three robots have been given a mission: to find and zap weeds with electricity, as advances in digitizing the electrical system continue to modernize power infrastructure, before planting seeds in the cleared soil.

The robots — named Tom, Dick and Harry — were developed by Small Robot Company to rid land of unwanted weeds with minimal use of chemicals and heavy machinery, complementing emerging options like electric tractors that aim to cut on-farm emissions.
The startup has been working on its autonomous weed killers since 2017, and this April launched Tom, its first commercial robot which is now operational on three UK farms. The other robots are still in the prototype stage, undergoing testing.

Small Robot says robot Tom can scan 20 hectares (49 acres) a day, collecting data, with AI-driven analysis guiding Dick, a "crop-care" robot, to zap weeds. Then it's robot Harry's turn to plant seeds in the weed-free soil.

Using the full system, once it is up and running, farmers could reduce costs by 40% and chemical usage by up to 95%, the company says, and integration with virtual power plants could further optimize energy use on electrified farms.

According to the UN Food and Agriculture Organization six million metric tons of pesticides were traded globally in 2018, valued at $38 billion.

"Our system allows farmers to wean their depleted, damaged soils off a diet of chemicals," says Ben Scott-Robinson, Small Robot's co-founder and CEO.

Zapping weeds
Small Robot says it has raised over £7 million ($9.9 million). Scott-Robinson says the company hopes to launch its full system of robots by 2023, which will be offered as a service at a rate of around £400 ($568) per hectare. The monitoring robot is placed at a farm first and the weeding and planting robots delivered only when the data shows they're needed — a setup that ultimately relies on a resilient grid, where research into preventing ransomware attacks is increasingly relevant.

To develop the zapping technology, Small Robot partnered with another UK-based startup, RootWave, while innovations like electricity from snow highlight the breadth of emerging energy tech.

"It creates a current that goes through the roots of the plant through the soil and then back up, which completely destroys the weed," says Scott-Robinson. "We can go to each individual plant that is threatening the crop plants and take it out."

"It's not as fast as it would be if you went out to spray the entire field," he says. "But you have to bear in mind we only have to go into the parts of the field where the weeds are." Plants that are neutral or beneficial to the crops are left untouched.

Small Robot calls this "per plant farming" — a type of precise agriculture where every plant is accounted for and monitored.

A business case
For Kit Franklin, an agricultural engineering lecturer from Harper Adams University, efficiency remains a hurdle, even as utilities use AI to adapt to electricity demands that could support wider on-farm electrification.

"There is no doubt in my mind that the electrical system works," he tells CNN Business. "But you can cover hundreds of hectares a day with a large-scale sprayer ... If we want to go into this really precise weed killing system, we have to realize that there is an output reduction that is very hard to overcome."

But Franklin believes farmers will adopt the technology if they can see a business case.

"There's a realization that farming in an environmentally friendly way is also a way of farming in an efficient way," he says. "Using less inputs, where and when we need them, is going to save us money and it's going to be good for the environment and the perception of farmers."

As well as reducing the use of chemicals, Small Robot wants to improve soil quality and biodiversity.

"If you treat a living environment like an industrial process, then you are ignoring the complexity of it," Scott-Robinson says. "We have to change farming now, otherwise there won't be anything to farm."

IRENA Climate Investment Platform accelerates renewable energy financing through de-risking, bankable projects, and public-private partnerships, advancing Paris Agreement goals via grid integration, microgrids, and decarbonization while expanding access, jobs, and sustainable economic growth.

Key Points

A global platform linking bankable renewable projects with finance, derisking and partners to scale decarbonization.

✅ Connects developers with banks, funds, and insurers

✅ Promotes de-risking via policy, PPAs, and legal frameworks

✅ Targets Paris goals with grid, microgrids, and off-grid access

The heads-of-state and energy ministers from more than 120 nations just met in Abu Dhabi and they had one thing in common: a passion to increase the use of renewable energy to reduce the threat from global warming — one that will also boost economic output and spread prosperity. Access to finance, though, is critical to this goal. 

Indeed, the central message to emerge from the conference hosted by the International Renewable Energy Agency (IRENA) this week in the United Arab Emirates is that a global energy transition is underway that has the potential to revitalize economies and to lift people out of poverty. But such a conversion requires international cooperation and a common desire to address the climate cause. 

“The renewable energy sector created jobs employing 11 million people in 2019 and provided off-grid solutions, having helped bring the number of people with no access to electricity to under 1 billion,” the current president of the UN General Assembly Tiijani Muhammad-Bande of Nigeria told the audience. 

Today In: Business
While renewables are improving energy access and reducing inequities, they also have the potential to curb CO2 emissions globally. The goal is to shrink them by 45% by 2030 and 90% by 2050, with Canada's net-zero race highlighting the role of renewable energy in achieving those targets. Getting there, though, requires progressive government policies that will help to attract financing. 

According to IRENA, investment in the clean energy sector is now at $330 billion a year. But if the 2050 goals are to be reached, those levels must nearly double to $750 billion annually. The green energy sector does not want to compete with the oil and gas sectors but rather, it is seeking to diversify fuel sources — a strategy that could help make electricity systems more resilient to climate risks. To hit the Paris agreement’s targets, it says that renewable energy deployment must increase by a factor of six.  

To that end, IRENA is forming a “climate investment platform” that will bring ideas to the table and then introduce prospective parties. It will focus on those projects that it believes are “bankable.”

It’s about helping project developers find banks, private companies and pension funds to finance their worthy projects, IRENA Director General Francesco La Camera said in response to this reporter’s question. Moreover, he said that the platform would work to ensure there is a sound legal structure and that there is legislative support to “de-risk” the investments. 

“Overcoming investment needs for energy transformation infrastructure is one of the most notable barriers to the achievement of national goals,” La Camera says. “Therefore, the provision of capital to support the adoption of renewable energy is key to low-carbon sustainable economic development and plays a central role in bringing about positive social outcomes.”

If the monies are to flow into new projects, governments have to create an environment where innovation is to be rewarded: tax incentives for renewables along with the design and implementation of transition plans. The aim is to scale up which in turn, leads to new jobs and greater economic productivity — a payback of three-to-seven times the initial investment.  

The path of least resistance, for now, is off-grid green energy solutions, or providing electricity to rural areas by installing solar panels that may connect to localized microgrids. Africa, which has a half-billion people without reliable electricity, would benefit. However, “If you want to go to scale and have bankable projects, you have to be connected to the grid,” Moira Wahba, with the UN Development Program, told this writer. “That requires large capital and private enterprise.”

Public policy must thus work to create the knowledge base and the advocacy to help de-risk the investments. Government’s role is to reassure investors that they will not be subject to arbitrary laws or the crony allocation of contracts. Risk takers know there are no guarantees. But they want to compete on a level playing. 

Analyzing Risk Profiles

He is speaking during the World Energy Future Summit.

How do foreign investors square the role of utilities that are considered safe and sound with their potential expansion into new fields such as investing in carbon-free electricity and in new places? The elimination of risk is not possible, says Mohamed Jameel Al Ramahi, chief executive officer of UAE-based Masdar. But the need to decarbonize is paramount. The head of the renewable energy company says that every jurisdiction has its own risk profile but that each one must be fully transparent while also properly structuring their policies and regulations. And there needs to be insurance for political risks. 

The United States and China, for example, are already “de-risked,” because they are deploying “gigawatts of renewables,” he told this writer. “When we talk about doubling the amount of needed investment, we have to take into account the risk profile of the whole world. If it is a high-risk jurisdiction, it will be difficult to bring in foreign capital.” 

The most compelling factor that will drive investment is whether the global community can comply with the Paris agreement, says Dr. Thani Ahmed Al Zeyoudi, Minister of the Ministry of Climate Change and the Environment for the United Arab Emirates. The goal is to limit increases to 2 degrees Celsius by mid-century, with the understanding that the UN’s latest climate report emphasizes that positive results are urgently needed. 

One of the most effective mechanisms is the public-private model. Governments, for example, are signing long-term power purchase agreements, giving project developers the necessary income they need to operate, and in the EU plans to double electricity use by 2050 are reinforcing these commitments. They can also provide grants and bring in international partners such as the World Bank. 

“We are seeing the impact of climate change with the various extreme events: the Australian fires, the cyclones and the droughts,” the minister told reporters. “We can no longer pass this to future generations to deal with.” 

The United Arab Emirates is not just talking about it, adds Sultan Al Jabber, chief executive of Abu Dhabi’s national oil company, Adnoc, who is also the former head of subsidiary Masdar. It is acting now, and across Europe Big Oil is turning electric as traditional players pivot too. His comments came during Abu Dhabi’s Sustainability Week at the World Future Energy Summit. The country is “walking the walk” by investing in renewable projects around the globe and it is growing its own green energy portfolio. Addressing climate change is “right” while it is also making “perfect economic sense.” 

The green energy transition has taken root in advanced economies while it is making inroads in the developing world — a movement that has the twin effect of addressing climate change and creating economic opportunities, and one that aligns with calls to transform into a sustainable electric planet for long-term prosperity. But private investment must double, which requires proactive governments to limit unnecessary risks and to craft the incentives to attract risk-takers.
