On vulnerable batteries, Canada’s about face, and France’s double down

Current conditions: New York City is digging out from upward of six inches of snow • Storm Emilia is deluging Spain with as much as 10 inches of rain • South Africa and Southern Australia are both at high risk of wildfires.
Last month, I told you about China’s latest attempt at fusion diplomacy, uniting more than 10 countries including France and the United Kingdom in an alliance to work together on the holy grail energy source. Over the weekend, The New York Times published a sweeping feature on China’s domestic fusion efforts, highlighting just how much Beijing is outspending the West on making the technology long mocked as “the energy source of tomorrow that always will be” a reality today. China went from spending nothing on fusion energy in 2021 to making investments this year that outmatch the rest of the world’s efforts combined. Consider this point of comparison: The Chinese government and private investors poured $2.1 billion into a new state-owned fusion company just the summer. That investment alone, the Times noted, is two and half times the U.S. Department of Energy’s annual fusion budget.
Still, the race between the two countries is heating up. Cumulative investment in fusion energy soared 30% between June and September to $15 billion, up from a little over $11 billion, according to a report by the European Union’s F4E Fusion Observatory written up by NucNet. That fusion is, as Heatmap's Katie Brigham has written, “finally, possibly, almost” arriving at the same time that data centers to power artificial intelligence are driving up electricity demand is fortuitous. Or, it would be, if AI doesn’t end up proving to be inflated by hype. On Friday, Wall Street showed jitters over the possibility that the bubble may burst, sending shares of companies such as Oracle and Nvidia plunging. It begs the question Katie raised in another story in September: What if we get fusion, but we don’t need it?
The South Korean battery manufacturer SK On canceled its partnership to work on electric vehicles with the Ford Motor Company, throwing the fate of the two companies’ three factories in the American Southeast into jeopardy. The announcement, E&E News reported, also casts doubt over the $9.6 billion loan the Biden administration gave the joint venture, known as Blue Oval SK. The collaboration came as American automakers teamed up with Korean battery companies to hasten the establishment of an EV supply chain. General Motors inked a deal with LG Energy Solution and Ford with SK On. But as sales of EVs flatline — due in part to President Donald Trump axing the federal tax credit for purchases of new electric vehicles — the nascent supply networks are withering on the vine. Ford isn’t down for the count, however. In August, as I wrote in the newsletter at the time, the company unveiled what it billed as its “Model T moment” for EVs, a whole new assembly line structure meant to scale up and iron out production of battery-powered cars.

Prime Minister Mark Carney has scrapped Canada’s carbon tax, inked major oil and gas deals, and pumped the brakes on a scheme to boost electric vehicle sales. Now the leader of the Liberal Party is facing blowback from allies and sustainability-minded executives who say the reversals put Canada’s net-zero goals out of reach. The former environment minister, Steven Guilbeault, quit the cabinet in protest, as have two founding members of the federal government’s Net Zero Advisory Body. “From a climate-science standpoint, this risks undermining the urgency of emissions reduction,” Paul Polman, the former chief executive of home-goods giant Unilever and a campaigner for sustainable capitalism, told the Financial Times. “Betting heavily on unproven massive-scale CCS [carbon capture and storage] and a cleaner-oil narrative while accelerating production ... seems like a gamble with global emissions targets, and with the credibility of net zero by 2050. Gambling with firm science does not seem smart to me.”

Utility-scale battery storage systems are facing increased risk of cyberattack from hackers working either for governments or criminal groups. That’s according to a white paper from the consultancies Brattle Group and Dragos. Battery deployments are expected to grow by as much as 45% in the next five years, raising the need for new protections against digital meddling. “Battery storage systems are being used across the grid to enable the deployment of variable demand sources such as solar and wind,” Phil Tonkin, field chief technology officer at Dragos, told Utility Dive’s sister publication Cybersecurity Dive. “This growing dependence makes them an attractive target.” Even relatively small-scale attacks can have devastating consequences. A single outage involving a 100-megawatt system for four hours in the U.S. would cost up to $1.2 million in revenue, the report found. A large-scale cyber attack that takes out 3,000 megawatts for a day would take a $39 million toll on the economy. Dragos is currently tracking as many as 18 groups that “are known to pose a threat to the electrical grid.”
Canada may be taking a U turn on climate policy, but France just updated its National Low-Carbon Strategy with an end date for using fossil fuels. The document “foresees the end of oil use between 2040 and 2045,” France24 reported, with natural gas phasing out by 2050. France is far ahead of most developed countries toward decarbonizing its power system since the nation has generated the majority of its electricity from nuclear reactors since the late 20th century. Under the plan, the French government expected electricity consumption to increase as heat pumps replace furnaces and electric vehicles swap in for diesel cars. Renewables are expected to cover the increase in electricity production.
Conspiracy theorists who think condensation trails from airplanes are some kind of population-control chemical may have their hands full with the paranoia fodder that geoengineering efforts represent. But actual scientists at Leipzig University have made a discovery about contrails’ effect on warming. The researchers found that “hidden” contrails within naturally forming cirrus clouds — previously not factored into assessments — contribute up to 10% of the warming all contrails cause. “We now know that not only the visible contrails we see in the sky but also those that form within clouds need to be taken into account when assessing the impact of aviation on the climate,” Torsten Seelig, the study's lead author, said in a statement.

Climate tech investors talk investing in moonshots at SF Climate Week.
Three climate investors walked onto a boat.
That’s not the start of a joke — it’s a description of a panel at Heatmap House, a day of conversations and roundtables with leading policymakers, executives, and investors at San Francisco Climate Week (at the Klamath, a venue made out of an old ship).
Heatmap’s Katie Brigham moderated the roundtable conversation with Prelude Ventures Managing Director Gabriel Kra, Azolla Ventures co-founder Matthew Nordan, and Toba Capital Partner Susan Su. Many of their investments are in moonshot climate technologies that other financial players might avoid.
“Things that look contrarian is kind of what we do,” said Kra. “Occasionally, there’s an idea that looks bad that’s actually a good idea.”
Prelude Ventures funds early-stage climate companies that are “weird, or non-consensus, or counter cyclical, or just ahead of the curve,” according to Kra.
Nordan, for instance, said he backs cultivated meat despite some doubts that the category will achieve widespread popularity.
“I’m presently leading an investment in a company called Pythag Technologies,” said Nordan, talking about the generative AI company focused on lab-grown meat. “It’s actually a really interesting time to invest counter-cyclically in a field like that.”
Like Nordan, Su described her firm as one that is open to unconventional choices.
“We are very weird in that we invest across lots of different categories and lots of different stages,” said Su.
One of her personal investments is in Xeno. “This company does electric motorbikes for commercial drivers, as well as swapping and energy networks in emerging markets, starting in East Africa,” she explained.
The panelists told Katie that opting for less popular investments can be rewarding because they may help fund a major breakthrough.
“We placed a couple of bets on fusion before this current melée occurred that sort of had everybody thinking that, you know, fusion was the next hot thing,” said Kra (who claimed that he intended the pun).
Nordan emphasized the gap that venture can fill, left by larger institutional investors who may shy away from high-risk technologies.
“If there are true breakthroughs out there that just may not be investable by mainstream finance at the earliest stages,” Nordan said, “not because people don’t think they’re really good ideas, but they may be crazy early-stage or kind of weird, or non-consensus, or counter-cyclical, or just ahead of the curve, it would be a real shame.”
Noise ordinances won’t necessarily stop a multi-resonant whine from permeating the area.
What did you do for Earth Day this year? I spent mine visiting a notoriously loud artificial intelligence campus in Virginia’s Data Center Alley. The experience brought home to me just how big a problem noise can be for the communities adjacent to these tech campuses – and how much further local officials have to go in learning how to deal with them.
The morning of April 22, I jumped into a Toyota Highlander and drove it out to the Vantage VA2 data center campus in Sterling, Virginia, smack dab in the middle of a large residential community. The sensation when I got out of the car was unignorable – imagine an all-encompassing, monotonous whoosh accompanied by a low rumble you can feel in your body. It sounds like a jet engine that never stops running or a household vacuum amplified to 11 running at all hours. It was rainy the day I visited and planes from nearby Dulles International Airport were soaring overhead, but neither sound could remotely eclipse the thudding, multi-resonant hum.
If you want to hear the sound for yourself, this video accurately sums it up.
After parking nearby I walked to one of the residential enclaves adjacent to VA2. One resident of a home across the street, who declined to give me her name, said she moved there before the project was completed. When asked how she felt about the noise, she told me, “It’s not as bad as it could be on the other side [of the data center], where all the equipment is.” (While the sound does get louder on the other side, I could clearly hear VA2 from her driveway.)
VA2’s noise has been causing problems for months, as documented by numerous social media posts, local news clips, and a feature published in Politico. It’s doubtful many of those living near the data center wanted it there. The project was built quite quickly – so quickly that Google Earth still shows undeveloped woodlands on the site. Per public filings, Vantage first proposed the facility in 2022 under the county’s fast-track commercial incentive program, an expedited permitting process for specific preferred industries. It was under construction as recently as October 2024, according to images captured by Google Street View.
Noise is one of the most common issues associated with data centers. At least a third of all conflicts over data centers are over noise complaints, and noise is the number one reason for opposition in cases where projects were ultimately canceled, according to Heatmap Pro data.
This issue goes back almost a decade. In 2019, residents of the Phoenix ex-urb Chandler, Arizona, became irate after a loud monotonous hmmmm began emanating from a CyrusOne data center. In that case, CyrusOne traced the noise back to chilling fans, and the company reduced the sound with muffling devices.
Chandler wound up adopting a new ordinance in 2023 requiring sound mitigation measures to prevent companies from exceeding certain ambient noise levels in the surrounding areas. That did nothing to improve the mood of the people who live there, however. Now Chandler, once known as a potential data center development hub, is now firmly in the anti- camp. The city council unanimously rejected a proposed $2.5 billion data center campus in December over noise concerns, despite an expensive lobbying push backed by former Arizona Senator Kyrsten Sinema.
As data centers spread across the U.S., noise is becoming an ever-more-common complaint. You can hear the familiar hum at a DataOne data center project in Vineland, New Jersey. DataOne told us they “understand concerns about ambient noise in the area” and are operating within the limits of local noise ordinances.
The hum is also in Dowegiac, Michigan, where people living nearby are calling their new Hyperscale Data facility a “noise trap,” with little explanation to date for the issue. Hyperscale Data did not respond to a request for comment.
And the hum is in Mount Pleasant, Wisconsin, where the sound from a new Microsoft data center campus rises above any din from rain. The hyperscaling giant is doing more to mitigate the issue than I’m used to seeing from data center developers, however.
On April 15, the company published an update on its own internal investigations into noise complaints. “Although the facility noise levels meet the requirements set by local ordinance, we take this feedback seriously and understand the impact this has had on our neighbors,” the update read. “We anticipated that our systems would need adjustments and create some noise as part of the datacenter startup, but we did not expect the tonal quality of the sound to travel as far as it has.”
To address the noise, Microsoft said it was “manually adjusting the cooling fans” to reduce noise, and that “we expect this change to address community concerns about the tonal humming.” On top of that, the company said it will install “additional sound reduction components” to “provide even further reductions in measured sound levels.” A Microsoft spokesperson told me in an email: “We’ve identified the source of the noise concerns and have implemented changes to significantly reduce sound from our facility.”
It isn’t cooling fans causing the noise at Vantage’s VA2 in Virginia, however. The sound, according to media reports, is coming from gas turbines powering the data center.
VA2 is one of the first in Virginia to function entirely off-grid, a design companies are adopting in order to avoid lengthy grid connection processes. Company spokesman Mark Freeman told me the facility is “fully compliant with all local noise ordinances, and this has been verified by third-party sound studies.”
“Additionally, in line with our commitment, we are actively working with third-party engineers to explore additional sound mitigation options,” Freeman continued. Freeman said “Our goal is to further reduce noise levels where possible and continue to foster a positive environment for everyone.”
Here’s the thing, though: I visited the Vantage campus after initially hearing from the company, and it was loud. Very loud.
I did not bring a decibel meter with me, so I cannot know whether they were operating within legal limits that day. What I do know is that noise ordinances struggle to properly capture sounds in multiple frequency ranges, making high and low frequencies challenging to regulate, according to the Environmental and Energy Study Institute, a bipartisan non-profit think tank. Officials representing Loudon County, where VA2 is located, have acknowledged that the local ordinance may need to change in order to address the most distressing frequencies from the data center campus.
“We can change the zoning ordinance and noise ordinance,” Loudon County supervisor Mike Turner told local TV station WUSA9 last week. “Noise can be mitigated. I just don’t believe that the noise problem cannot be solved.”
I wrote Freeman, the Vantage spokesman, to tell him I had visited the VA2 campus and found the noise to be “quite foul.” He replied soon after, telling me that Vantage is going “above and beyond what is required in order to address concerns from nearby residents.” The company is using “targeted enhancements to turbine-related equipment such as dampening equipment, enclosure inlets and enclosure exhausts.” These measures “represent meaningful progress and will help us better evaluate the effectiveness of the broader solutions under consideration.” Freeman also said the company is “actively assessing additional options” focused on “targeted frequency ranges.”
As we continue to track local regulation of data centers, I’m we’ll see many more cases like VA2, in which obtrusive sound prompts forms of regulation we may have never seen before.
Or, people will just hear these noises and say no to more data centers.
Plus more of the week’s biggest project development fights.
