A team of scientists at MIT has discovered a new way to generate power with carbon nanotubes.

In a paper titled "Chemically driven carbon-nanotube-guided thermopower waves" published in Nature Materials, they describe how they made "thermopower waves" flow through the nanotubes, generating a significant amount of power relative to the size of the nanotubes. This opens up new areas of research in energy generation and storage.

In the new experiments, each of these electrically and thermally conductive nanotubes was coated with a layer of a reactive fuel that can produce heat by decomposing. This fuel was then ignited at one end of the nanotube using either a laser beam or a high-voltage spark, and the result was a fast-moving thermal wave traveling along the length of the carbon nanotube like a flame speeding along the length of a lit fuse. Heat from the fuel goes into the nanotube, where it travels thousands of times faster than in the fuel itself. As the heat feeds back to the fuel coating, a thermal wave is created that is guided along the nanotube. With a temperature of 3,000 kelvins, this ring of heat speeds along the tube 10,000 times faster than the normal spread of this chemical reaction. The heating produced by that combustion, it turns out, also pushes electrons along the tube, creating a substantial electrical current.

After further development, the system now puts out energy, in proportion to its weight, about 100 times greater than an equivalent weight of lithium-ion battery.

What's surprising about this is that the amount of power released is much higher than what standard thermoelectric calculations predict. Something is going on with carbon nanotubes when they are heated up that isn't happening on the same scale with other semi-conductors.

The researchers suggest that these specially coated carbon nanotubes could be used to power extremely small devices and sensors. These could be used to gather environmental data out in the field and help us better understand our planet and its ecosystems, for example. The beauty would be that unlike regular batteries, the energy would not leak out with time, it would only go down when the device is in use.

The technology could also be scaled up to power larger devices, but this seems technically challenging on many levels. How do you re-coat the nanotubes once the fuel has been used? Would this lead to very energy-dense one-time-use batteries? If the fuel doesn't leave behind toxic by-products and it's not too hard to re-coat the nanotubes, maybe this could make sense. But if the fuel is toxic and the nanotubes are hard to re-coat, do we want this on a large scale?

We'll have to wait to see if the technology can be refined enough to have real-world uses. With some luck, this is just the start of a long chain of discoveries that will lead to a world-changing energy storage solution.

Wind Denmark - Danish electricity generation sets a new green record

Denmark 2019 electricity CO2 intensity shows record-low emissions as renewable energy surges, wind power dominates, offshore wind expands, and coal phase-out accelerates Denmark's energy transition and grid decarbonization, driven by higher CO2 prices and flexibility.

 

Key Points

It is 135 g CO2/kWh, a record low enabled by wind power growth, offshore wind, and a sharp coal decline.

✅ Average emissions fell to 135 g CO2/kWh, the lowest on record

✅ Wind and solar supplied 49.9% of national electricity use

✅ Coal consumption dropped 46% as CO2 allowance prices rose

 

Danish electricity producers set a new green record in 2019, when an average produced kilowatt-hour emitted 135 gr CO2 / kWh.

It is the lowest CO2 emission ever measured in Denmark and about one-seventh of what the electricity producers emitted in 1990.

Never has a kilowatt-hour produced emitted as little CO2 as it did in 2019. And that's according to Energinet's recently published annual Environmental Report on Danish electricity generation and cogeneration, two primary causes.

One reason is that more green power has been produced because the Horns Rev 3 offshore wind farm, which can produce electricity for 425,000 households, was commissioned in 2019. The other is that Danish coal consumption fell by 46 percent from 2018 to 2019, as coal phase-out plans gathered pace across the sector. the dramatic decline in coal consumption is partly due a significant increase in the price of CO2 quotas, and thus also the price of CO2 emissions.

'Historically, 135 gr CO2 / kWh is a really, really low figure, showing the impressive green travel that the Danish electricity system has been on. In 1990, a kilowatt-hour produced emitted over 1000 grams of CO2, ie about seven times as much as today, 'says Hanne Storm Edlefsen, area manager in Energinet Power Systems Responsibility.

Wind energy is the dominant form of electricity generation in Denmark, a pattern the UK wind beat coal in 2016 when shifting away from fossil fuels.

17.1 TWh. Danish wind turbines and solar cells generated so much electricity in 2019, corresponding to 49.9 per cent. of Danish electricity consumption, reflecting broader EU wind and solar growth trends as well. An increase of 15 per cent. The wind turbines alone produced 16 TWh, which is not only a new green record, but also puts a thick line that wind energy is by far the most dominant form of electricity generation in Denmark.

'Thanks to our large wind resources, turbines are by far the largest supplier of renewable energy in Denmark, and this will be for many years to come. The large price drop in new wind energy in recent years - for both onshore and offshore winds - will ensure that wind energy will drive a large part of the growth in renewable energy in the coming years, as new wind generation records are set in markets like the UK, 'says Soren Klinge, electricity market manager at Wind Denmark.

Conversely, total electricity generation from fossil and bio-based fuels decreased by 26 PJ (petajoule ed.), Corresponding to 34 per cent. from 2018 to 2019, mirroring renewables overtaking coal in Germany. Nevertheless, net electricity generation was just under 30 TWh both years.

'It is worth noting that while fossil fuels are being phased out, Denmark maintains its annual net production of electricity. The green, so to speak, replaces the black. It once again underpins that green conversion, high security of supply and an affordable electricity price can go hand in hand, 'says Hanne Storm Edlefsen.

Danish power system is ready for a green future

Including trade in electricity with neighboring countries, 1 kWh in a Danish outlet generates 145 gr CO2 / kWh.

'There has been a very significant development in the Danish electricity system in recent years, where the electricity system can now be operated solely on the renewable energy. It is a remarkable development, also from an international perspective where low-carbon progress stalled in the UK in 2019, that one would not have thought possible for just a few years ago, 'he says.

More than expected have phased out coal

The electricity from the Danish sockets will be greener , predicts Energinet's environmental report , which expects CO2 intensity in the coming years. This is explained by an expectation of increased electrification of energy consumption, together with a continued expansion with wind and solar.

'Wind energy is the cornerstone of the green transition. With the commissioning of the Kriegers Flak offshore wind farm and several major onshore wind turbine projects within the next few years, we can well expect that only the wind's share of electricity consumption will exceed 50 per cent hopefully as early as 2021,' concludes Soren Klinge.

Green hydrogen, green energy: inside Brazil's $5.4bn green hydrogen plant

Enegix Base One Green Hydrogen Plant will produce renewable hydrogen via electrolysis in Ceara, Brazil, leveraging 3.4 GW baseload renewables, offshore wind, and hydro to scale clean energy, storage, and export logistics.

 

Key Points

A $5.4bn Ceara, Brazil project to produce 600m kg of green hydrogen annually using 3.4 GW of baseload renewables.

✅ 3.4 GW baseload from hydro and offshore wind pipelines

✅ Targets 600m kg green hydrogen per year via electrolysis

✅ Focus on storage, transport, and export supply chains

 

In March, Enegix Energy announced some of the most ambitious hydrogen plans the world has ever seen. The company signed a memorandum of understanding (MOU) with the government of the Brazilian state of Ceará to build the world’s largest green hydrogen plant in the state on the country’s north-eastern coast, and the figures are staggering.

The Base One facility will produce more than 600 million kilograms of green hydrogen annually from 3.4GW of baseload renewable energy, and receive $5.4bn in investment to get the project off the ground and producing within four years.

Green hydrogen, hydrogen produced by electrolysis that is powered by renewables, has significant potential as a clean energy source. Already seeing increased usage in the transport sector, the power source boasts the energy efficiency and the environmental viability to be a cornerstone of the world’s energy mix.

Yet practical challenges have often derailed large-scale green hydrogen projects, from the inherent obstacle of requiring separate renewable power facilities to the logistical and technological challenges of storing and transporting hydrogen. Could vast investment, clever planning, and supportive governments and programs like the DOE’s hydrogen hubs initiative help Enegix to deliver on green hydrogen’s oft-touted potential?

Brazilian billions
The Base One project is exceptional not only for its huge scale, but the timing of its construction, with demand for hydrogen set to increase dramatically over the next few decades. Figures from Wood Mackenzie suggest that hydrogen could account for 1.4 billion tonnes of energy demand by 2050, one-tenth of the world’s supply, with green hydrogen set to be the majority of this figure.

Yet considering that, prior to the announcement of the Enegix project, global green hydrogen capacity was just 94MW, advances in offshore green hydrogen and the development of a project of this size and scope could scale up the role of green hydrogen by orders of magnitude.

“We really need to [advance clean energy] without any emissions on a completely clean, carbon neutral and net-zero framework, and so we needed access to a large amount of green energy projects,” explains Wesley Cooke, founder and CEO of Enegix, a goal aligned with analyses that zero-emissions electricity by 2035 is possible, discussing the motivation behind the vast project.

With these ambitious goals in mind, the company needed to find a region with a particular combination of political will and environmental traits to enable such a project to take off.


“When we looked at all of these key things: pipeline for renewables, access to water, cost of renewables, and appetite for renewables, Brazil really stood out to us,” Cooke continues. “The state of Ceará, that we’ve got an MOU with the government in at the moment, ticks all of these boxes.”

Ceará’s own clean energy plans align with Enegix’s, at least in terms of their ambition and desire for short-term development. Last October, the state announced that it plans to add 5GW of new offshore wind capacity in the next five years. With BI Energia alone providing $2.5bn in investment for its 1.2GW Camocim wind facility, there is significant financial muscle behind these lofty ambitions.

“One thing I should add is that Brazil is very blessed when it comes to baseload renewables,” says Cooke. “They have an incredibly high percentage of their country-wide energy that comes from renewable sources and a lot of this is in part due to the vast hydro schemes that they have for hydro dams. Not a lot of countries have that, and specifically when you’re trying to produce hydrogen, having access to vast amounts of renewables [is vital].”

Changing perceptions and tackling challenges
This combination of vast investment and integration with the existing renewable power infrastructure of Ceará could have cultural impacts too. The combination of state support for and private investment in clean energy offsets many of the narratives emerging from Brazil concerning its energy policies and environmental protections, even as debates over clean energy's trade-offs persist in Brazil and beyond, from the infamous Brumadinho disaster to widespread allegations of illegal deforestation and gold mining.

“I can’t speak for the whole of Brazil, but if we look at Ceará specifically, and even from what we’ve seen from a federal government standpoint, they have been talking about a hydrogen roadmap for Brazil for quite some time now,” says Cooke, highlighting the state’s long-standing support for green hydrogen. “I think we came in at the perfect time with a very solid plan for what we wanted to do, [and] we’ve had nothing but great cooperation, and even further than just cooperation, excitement around the MOU.”

This narrative shift could help overcome one of the key challenges facing many hydrogen projects, the idea that its practical difficulties render it fundamentally unsuitable for baseload power generation. By establishing a large-scale green hydrogen facility in a country that has recently struggled to present itself as one that is invested in renewables, the Base One facility could be the ultimate proof that such clean hydrogen projects are viable.

Nevertheless, practical challenges remain, as is the case with any energy project of this scale. Cooke mentions a number of solutions to two of the obstacles facing hydrogen production around the world: renewable energy storage and transportation of the material.

“We were looking at compressed hydrogen via specialised tankers [and] we were looking at liquefied hydrogen, [as] you have to get liquefied hydrogen very cool to around -253°, and you can use 30% to 40% of your total energy that you started with just to get it down to that temperature,” Cooke explains.

“The other aspect is that if you’re transporting this internationally, you really have to think about the supply chain. If you land in a country like Indonesia, that’s wonderful, but how do you get it from Indonesia to the customers that need it? What is the supply chain? What does that look like? Does it exist today?”

The future of green hydrogen
These practical challenges present something of a chicken and egg problem for the future of green hydrogen: considerable up-front investment is required for functions such as storage and transport, but the difficulties of these functions can scare off investors and make such investments uncommon.

Yet with the world’s environmental situation increasingly dire, more dramatic, and indeed risky, moves are needed to alter its energy mix, and Enegix is one company taking responsibility and accepting these risks.

“We need to have the renewables to match the dirty fuel types,” Cooke says. “This [investment] will really come from the decisions that are being made right now by large-scale companies, multi-billion-euro-per-year revenue companies, committing to building out large scale factories in Europe and Asia, to support PEM [hydrolysis].”

This idea of large-scale green hydrogen is also highly ambitious, considering the current state of the energy source. The International Renewable Energy Agency reports that around 95% of hydrogen comes from fossil fuels, so hydrogen has a long ways to go to clean up its own carbon footprint before going on to displace fossil fuel-driven industries.

Yet this displacement is exactly what Enegix is targeting. Cooke notes that the ultimate goal of Enegix is not simply to increase hydrogen production for use in a single industry, such as clean vehicles. Instead, the idea is to develop green hydrogen infrastructure to the point where it can replace coal and oil as a source of baseload power, leapfrogging other renewables to form the bedrock of the world’s future energy mix.

“The problem with [renewable] baseload is that they’re intermittent; the wind’s not always blowing and the sun’s not always shining and batteries are still very expensive, although that is changing. When you put those projects together and look at the levelised cost of energy, this creates a chasm, really, for baseload.

“And for us, this is really where we believe that hydrogen needs to be thought of in more detail and this is what we’re really evangelising about at the moment.”

A more hydrogen-reliant energy mix could also bring social benefits, with Cooke suggesting that the same traits that make hydrogen unwieldy in countries with established energy infrastructures could make hydrogen more practically viable in other parts of the world.

“When you look at emerging markets and developing markets at the moment, the power infrastructure in some cases can be quite messy,” Cooke says. “You’ve got the potential for either paying for the power or extending your transmission grid, but rarely being able to do both of those.

“I think being able to do that last mile piece, utilising liquid organic hydrogen carrier as an energy vector that’s very cost-effective, very scalable, non-toxic, and non-flammable; [you can] get that power where you need it.

“We believe hydrogen has the potential to be very cost-effective at scale, supporting a vision of cheap, abundant electricity over time, but also very modular and usable in many different use cases.”

Biden's Announcement of a 100% Tariff on Chinese-Made Electric Vehicles

U.S. 100% Tariff on Chinese EVs aims to protect domestic manufacturing, counter subsidies, and reshape the EV market, but could raise prices, disrupt supply chains, invite retaliation, and complicate climate policy and trade relations.

 

Key Points

A 100% import duty on Chinese EVs to boost U.S. manufacturing, counter subsidies, and address supply chain risks.

✅ Protects domestic EV manufacturing and jobs

✅ Counters alleged subsidies and IP concerns

✅ May raise prices, limit choice, trigger retaliation

 

President Joe Biden's administration recently made headlines with its announcement of a 100% tariff on Chinese electric vehicles (EVs), marking a significant escalation in trade tensions between the two economic powerhouses. The decision, framed as a measure to protect American industries and promote domestic manufacturing, has sparked debates over its potential impact on the EV market, global supply chains, and bilateral relations between the United States and China.

The imposition of a 100% tariff on Chinese-made EVs reflects the Biden administration's broader efforts to revitalize the American automotive industry and promote the transition to electric vehicles as part of its climate agenda and tighter EPA emissions rules that could accelerate adoption. By imposing tariffs on imported EVs, particularly those from China, the administration aims to incentivize domestic production and create jobs in the growing green economy, and to secure critical EV metals through allied supply efforts. Additionally, the tariff is seen as a response to concerns about unfair trade practices, including intellectual property theft and market distortions, allegedly perpetuated by Chinese companies.

However, the announcement has triggered a range of reactions from various stakeholders, with both proponents and critics offering contrasting perspectives on the potential consequences of such a policy. Proponents argue that the tariff will help level the playing field for American automakers, who face stiff competition from Chinese companies benefiting from government subsidies and lower production costs. They contend that promoting domestic manufacturing of EVs will not only create high-quality jobs but also enhance national security by reducing dependence on foreign supply chains at a time when an EV inflection point is approaching.

On the other hand, critics warn that the 100% tariff on Chinese-made EVs could have unintended consequences, including higher prices for consumers, as seen in the UK EV prices and Brexit debate, disruptions to global supply chains, and retaliatory measures from China. Chinese EV manufacturers, such as NIO, BYD, and XPeng, have been gaining momentum in the global market, offering competitive products at relatively affordable prices. The tariff could limit consumer choice at a time when U.S. EV market share dipped in Q1 2024, potentially slowing the adoption of electric vehicles and undermining efforts to combat climate change and reduce greenhouse gas emissions.

Moreover, the tariff announcement comes at a sensitive time for U.S.-China relations, which have been strained by various issues, including trade disputes, human rights concerns, and geopolitical tensions. The imposition of tariffs on Chinese-made EVs could further exacerbate bilateral tensions, potentially leading to retaliatory measures from China and escalating trade frictions. As the world's two largest economies, the United States and China have significant economic interdependencies, and any escalation in trade tensions could have far-reaching implications for global trade and economic stability.

In response to the Biden administration's announcement, Chinese officials have expressed concerns and called for dialogue to resolve trade disputes through negotiation and mutual cooperation. China has also emphasized its commitment to fair trade practices and compliance with international rules and regulations governing trade.

Moving forward, the Biden administration faces the challenge of balancing its domestic priorities with the need to maintain constructive engagement with China and other trading partners, even as EV charging networks scale under its electrification push. While promoting domestic manufacturing and protecting American industries are legitimate policy goals, achieving them without disrupting global trade and undermining diplomatic relations requires careful deliberation and strategic foresight.

In conclusion, President Biden's announcement of a 100% tariff on Chinese-made electric vehicles reflects his administration's commitment to revitalizing American industries and promoting domestic manufacturing. However, the decision has raised concerns about its potential impact on the EV market, global supply chains, and U.S.-China relations. As policymakers navigate these complexities, finding a balance between protecting domestic interests and fostering international cooperation will be crucial to achieving sustainable economic growth and addressing global challenges such as climate change.

Multi-billion-dollar hydro generation project proposed for Meaford military base

Meaford Pumped Storage Project aims to balance the grid with hydro-electric generation, a hilltop reservoir, and transmission lines near Georgian Bay, pending environmental assessment, permitting, and federal review of impacts on fish and drinking water.

 

Key Points

TC Energy proposal to pump water uphill off-peak and generate 1,000 MW at peak, pending studies and approvals.

✅ Balances grid by storing off-peak energy and generating at peak.

✅ Requires reservoir, break wall, transmission lines, generating station.

✅ Environmental studies and federal review underway before approvals.

 

Plans for a $3.3 billion hydro-electric project in Meaford are still in the early study stages, but some residents have concerns about what it might mean for the environment, as past Site C stability issues have illustrated for large hydro projects.

A one-year permit was granted for TC Energy Corporation (TC Energy) to begin studies on the proposed location back in May, and cross-border projects like the New England Clean Power Link require federal permits as well to proceed. Local municipalities were informed of the project in June.

TC Energy is proposing to have a pumped storage project at the 4th Canadian Division Training (4CDTC) Meaford property, which is on federal lands.

A letter sent to local municipalities explains that the plan is to balance supply and demand on the electrical grid by pumping water uphill during off-peak hours. It would then release the water back into Georgian Bay during peak periods, generating up to 1,000 megawatts of electricity.

The project is expected to create 800 jobs over four years of construction, in addition to long-term operational positions.


 

According to the company's website, the proposed pump station would require a large reservoir on the military base, a generating station, transmission lines infrastructure, and a break wall 850 metres from shore.

Some residents fear the project will threaten the bay and the fish, echoing Site C dam concerns shared with northerners, and the region's drinking water.

Meaford's mayor says the town has no jurisdiction on federal lands, but that a list of concerns has been forwarded to the company, while Ontario First Nations have urged government action on urgent transmission needs elsewhere.

TC Energy will tackle preliminary engineering and environmental studies to determine the feasibility of the proposed location, which could take up to two years.

Once the assessments are done, they need to be presented to the government for further review and approval, as seen when Ottawa's Site C stance left work paused pending a treaty rights challenge.

TC Energy's website states that the company anticipates construction to begin in 2022 if it gets all the go-ahead, with the plant to begin operations four years later.

Input from residents is being collected until April 2020, similar to when the National Energy Board heard oral traditional evidence on the Manitoba-Minnesota transmission line.

The Banker Trying to Fix the UK's Electricity Grid

UK power grid bottleneck is stalling renewable energy, with connection queues, planning delays, and transmission infrastructure gaps raising costs, slowing decarbonization, and deterring investment as government considers reforms led by a new chief adviser.

 

Key Points

Delays and capacity gaps that hinder connecting new generation and demand, raising costs and slowing decarbonization.

✅ Connection queues delay projects for years

✅ Planning and NIMBY barriers stall transmission builds

✅ Investment costs on bills risk political pushback

 

During his three decades at investment bank Morgan Stanley, Franck Petitgas developed a reputation for solving problems that vexed others. Fixing the UK’s creaking power grid could be his most challenging task yet.

Earlier this year, Prime Minister Rishi Sunak appointed Petitgas as his chief business adviser, and the former financier has been pushing to tackle the gridlock that’s left projects waiting endlessly for a connection, an issue he sees as one of the biggest problems for industry.

But there are no easy solutions to tackle the years-long queue to get on the grid or the drawn-out planning process for building clean power generation, with the energy transition stalled by supply delays compounding the problem. And sluggish progress in expanding and improving the electricity network is preventing the construction of new housing developments and offices, as well as slowing the transition to greener power.

That transition has already taken a knock after Sunak last week controversially watered down some of the UK’s climate ambitions, citing in part the cost to consumers. He also acknowledged the issues surrounding the grid and promised the “most transformative plans” in response, drawing on lessons from Europe’s power crisis where applicable. Those are due to be unveiled within weeks. 

Shortly after his appointment, Petitgas offered reassurances to business leaders at a meeting in Downing Street that solutions were being worked on, according to people familiar with the matter. But there’s a lack of confidence across business that enough will be done.

Cost is a big factor in the expansion of the electricity grid, and some argue a state-owned generation model could ease bills over time. Improving the onshore network alone could require investment of between £100 billion and £240 billion ($122-$293 billion) by 2050, according to a government analysis last year. 

With network expansion funded through power bills, that’s a big ask, particularly with Sunak trailing in polls ahead of an election expected next year.

“It’s very difficult for politicians to say more money should be on bills,” said Emma Pinchbeck, chief executive of Energy UK, a trade body. “So you get to a situation where no one wants to pay for the infrastructure investment until it’s really sticky, and that’s where we’ve got to with the grid.”

There are huge competitive and economic implications if the UK falls further behind. With US President Joe Biden spending an estimated $370 billion on climate measures through his Inflation Reduction Act, and China already a world leader in electric vehicles, Britain’s grid inaction is holding it back in the global race to decarbonize, said Jess Ralston, an analyst at the Energy and Climate Intelligence Unit think tank.

“The UK is dithering and delaying, and not making any strategic decisions,” she said. “You can see companies just saying ‘I’m going to the US, or I’m going to China’.” 

In a statement, the government said it’s a “priority to speed up the time taken to connect new power generators and power consumers to the grid.” It added that it’s taking “significant steps to accelerate grid infrastructure,” including support for new Channel interconnectors announced this year.

The government expects demand for electricity to double by 2035 and that will mean more generation that needs to be linked up to the network by cables and pylons. Local grids will also have to expand to accommodate more connection points for electric vehicles and homes, and invest in large-scale energy storage capacity to balance supply.

But so far, the rapid rise in renewable energy investment has not been accompanied by matching spend on the power network, according to BloombergNEF, a pattern seen in Germany’s grid expansion woes as well.

“The pace and scale of what we now have to deliver is significantly different from the last few decades,” said Carl Trowell, president of UK strategic infrastructure at National Grid. “It’s a national endeavor.”

In June, Electricity Networks Commissioner Nick Winser sent the government recommendations for how to accelerate construction of more transmission infrastructure. He said efforts to decarbonize the power sector will be “wasted if we cannot get the power to homes and businesses.”

“We need a seriously stronger sense of urgency,” said Kevin O’Donovan, country manager for Statkraft UK, which is holding off investment in four wind farms and two solar projects due to grid connection delays.

In addition to cost, the other major stumbling block is planning. Politicians in the governing Conservative Party are wary of angering voters with new infrastructure in rural areas that typically vote Tory. Across the country, “Not In My Back Yard” campaigners – NIMBYs — pose a major challenge to projects.

Petitgas, 62, retired from Morgan Stanley last year after nearly 30 years at the bank, where he led its international division from London. The issues over connections and planning have been repeatedly pointed out to Petitgas by investors and trade groups over a series of meetings this year, according to people familiar with the matter, requesting anonymity discussing private talks.

Yet with a general election looming and the issue plagued by political headaches, many are skeptical that Sunak can find the solutions needed.

One business chief said Downing Street considers the issue too tricky and expensive to tackle in the short-term. Others are concerned that while Petitgas has license from Sunak, he doesn’t have influence across the relevant departments to get grids to the top of the agenda.

 

Wind Farms

Multiple parts of the UK’s climate plans are under pressure. Earlier this month, an auction for contracts to build new wind farms received zero bids from developers, even as wind leads the power mix in many regions, marking yet another green setback. 

The UK is already behind on its target of having 50 gigawatts of offshore wind built by 2030, up from 14 GW today. The challenge is accelerating development without railroading local communities.

Within Sunak’s Conservative Party, some lawmakers are pushing back on new infrastructure in their local areas. A group including Environment Secretary Therese Coffey and former Home Secretary Priti Patel is campaigning against building new pylons across a stretch of eastern England.

According to Adam Bell, director of policy at consultancy Stonehaven, backbench pressure means Sunak is unlikely to take major action on the grid in the near term. He doesn’t see the prime minister accepting Winser’s recommendations, least of all accelerating planning decisions.

“Over the last year, Sunak has favored party management over things that will benefit the country,” Bell said.

Romania enhances safety at Cernavoda, IAEA reports

IAEA OSART Cernavoda highlights strengthened operational safety at Romania’s Cernavoda NPP, citing improved maintenance practices, simulator training, and deficiency reporting, with ongoing actions on spare parts procurement, procedure updates, and chemical control for nuclear compliance.

 

Key Points

An IAEA follow-up mission confirming improved operational safety at Cernavoda NPP, with remaining actions tracked.

✅ Enhanced simulator training and crew performance

✅ Improved field deficiency identification and reporting

✅ Ongoing upgrades to procedures, spares, and chemical control

 

The International Atomic Energy Agency (IAEA) said yesterday that the operator of Romania’s Cernavoda nuclear power plant had demonstrated "strengthened operational safety" by addressing the findings of an initial IAEA review in 2016. The Operational Safety Review Team (OSART) concluded a five-day follow-up mission on 8 March to the Cernavoda plant, which is on the Danube-Black Sea Canal, about 160 km from Bucharest.

The plant's two 706 MWe CANDU pressurised heavy water reactors, reflecting Canadian nuclear projects, came online in 1996 and 2007, respectively.

The OSART team was led by Fuming Jiang, a senior nuclear safety officer at the IAEA, which recently commended China's nuclear security in separate assessments.

"We saw improvements in key areas, such as the procurement of important spare parts, the identification and reporting of some deficiencies, and some maintenance work practices, as evidenced by relevant performance indicators," Jiang said, noting milestones at nuclear projects worldwide this year.

The team observed that several findings from the 2016 review had been fully addressed, including: enhanced operator crew performance during simulator training; better identification and reporting of deficiencies in the field; and improvement in maintenance work practices.

More time is required, it said, to fully implement some actions, including: further improvements in the procurement of important spare parts with relevance to safety; further enhancement in the revision and update of some operating procedures, drawing on lessons from Pickering NGS life extensions undertaken in Ontario; and control and labelling of some plant chemicals.

Dan Bigu, site vice president of Cernavoda NPP, said the 2016 mission had "proven to be very beneficial", adding that the current follow-up mission would "provide further catalyst support to our journey to nuclear excellence".

The team provided a draft report of the mission to the plant's management and a final report will be submitted to the Romanian government, which recently moved to terminate talks with a Chinese partner on a separate nuclear project, within three months.

OSART missions aim to improve operational safety by objectively assessing safety performance, even as the agency reports mines at Ukraine's Zaporizhzhia plant amid ongoing risks, using the IAEA's safety standards and proposing recommendations and suggestions for improvement where appropriate. The follow-up missions are standard components of the OSART programme and, as the IAEA has warned of risks from attacks on Ukraine's power grids, are typically conducted within two years of the initial mission.
