On deep-sea mining, New York nuclear, and kestrel symbiosis

Current conditions: Winter Storm Fern buried broad swaths of the country, from Oklahoma City to Boston • Intense flooding in Zimbabwe and Mozambique have killed more than 100 people • South Australia’s heat wave is raging on, raising temperatures as high as 113 degrees Fahrenheit.
The United States’ aging grid infrastructure faces a test every time the weather intensifies, whether that’s heat domes, hurricanes, or snow storms. The good news is that pipeline winterization efforts that followed the deadly blackouts in 2021’s Winter Storm Uri made some progress in keeping everything running in the cold. The bad news is that nearly a million American households still lost power amid the storm. Tennessee, Mississippi, and Louisiana were the worst hit, with hundreds of thousands of households left in the dark, according to live data on the Power Outage tracker website. Georgia and Texas followed close behind, with roughly 75,000 customers facing blackouts. Kentucky had the next-most outages, with more than 50,000 households disconnected from the grid, followed by South Carolina, West Virginia, North Carolina, Virginia, and Alabama. Given the prevalence of electric heating in the typically-warmer Southeast, the outages risked leaving the blackout region without heat. Gas wasn’t entirely reliable, however. The deep freeze in Texas halted operations at roughly 10% of the Gulf Coast’s petrochemical facilities and refineries, Bloomberg reported.
On Saturday, right before Winter Storm Fern began, the Department of Energy issued its first emergency order of the year to deploy backup generation in Texas in hopes of avoiding a repeat of Uri. As of Sunday evening, data from Electric Reliability Council of Texas, the state’s grid operator, showed natural gas providing nearly 60% of the electricity on the wires, with coal and wind neck-and-neck for second place and solar in a close fourth. It’s a relief that the grid is holding. But the overreliance on fossil fuels isn’t a good long-term strategy. While “climate change deniers love to use major winter storms as ‘proof’ that global warming isn’t real,” my colleague Jeva Lange wrote last week, “in the case of this weekend’s polar vortex, there is evidence that Arctic warming is responsible for the record cold temperature projections across the United States.”

The National Oceanic and Atmospheric Administration finalized a rule last week clearing the way for companies to apply for the right to mine the deep ocean floor. Under the new rules, applications for commercial and exploratory licenses are streamlined into a single process, cutting the number of required environmental assessments and public comment hearings in half. The day after the final rule came out, The Metals Company, the leading startup racing to collect mineral-rich nodules from largely unexplored depths of international waters, submitted an application to mine an area roughly twice the size of its original plans. “Nearly 50 years after this industry took shape, it’s ready to move forward,” the company told The New York Times. But opposition to deep-sea mining is mounting as environmentalists highlight the risk the industry poses to a scarcely understood and still remarkably untouched ecosystem. A corporate campaign to oppose deep sea mining just added the solar giant Sunrun to its petition, as I told you last week.
Tesla has officially discontinued Autopilot, its basic self-driving software, in the U.S. and Canada. All new car purchases now come with standard Traffic-Aware Cruise Control, Sawyer Merritt, a self-described Tesla investor with a prolific social media presence, wrote in a post on X. The move, according to TechCrunch, is designed to boost adoption of Tesla’s more advanced Full Self-Driving setting. But it’s also in response to a courtroom loss in the company’s biggest market. Last month, a judge in California ruled that Tesla engaged in deceptive marketing by overstaying the capabilities of both Autopilot and FSD for years. The California Department of Motor Vehicles, which originally brought the case, gave Tesla two months to comply with the ruling by dropping the Autopilot name.

New York Governor Kathy Hochul is going all in on nuclear power. She started off last year at the helm of a new multi-state alliance working on building more reactors. Over the summer, she directed the state-owned power authority to oversee construction of New York’s first new reactor since the 1980s. More recently, she inked a deal with Ontario to work together on building new plants and expanded her target fivefold to 5 gigawatts of new atomic energy in the state. Now she’s backed something a little more traditional but no less important. Last week, the state’s utility regulators extended subsidies for existing nuclear plants by another two decades in hopes of keeping aging reactors open until at least 2049.
In Denmark, meanwhile, the government has officially started considering building small modular reactors and lifting the nuclear ban the parliament put into effect 40 years ago. “Green energy from solar and wind is now and will continue to be the backbone of the Danish energy supply, but we can also see that it cannot stand alone,” Lars Aagaard, Denmark’s climate, energy and utilities minister, said in a statement. “We must be open to examining whether other technologies can provide us with green energy in the future. Small modular nuclear reactors may be an option.”
Standard Nuclear, a startup producing TRISO atomic fuel required by several of the nation’s leading small modular reactor designs, has raised $140 million in Series A funding. The investment round was led by Decisive Point, with first-time backing from Chevron Technology Ventures, StepStone Group, and XTX Ventures. Several existing investors, including Fundomo, Andreessen Horowitz, and Crucible Capital, increased their stakes. The financing will support Standard Nuclear’s plans to expand TRISO production to over 2 metric tons per year at multiple sites across the country. The timeline, the company said, is “rapid” and will take place by mid-2026. “With this funding, we are positioned to accelerate our roadmap, scale operations, and deliver on the promise to fuel the next generation of reactors powering industry, defense, and space,” Kurt Terrani, Standard Nuclear’s chief executive, said in a statement.
While TRISO was invented decades ago, the fuel — which has extra layers of ceramic coating that are meant to make a meltdown virtually impossible — is making a comeback as the go-to material for next-generation reactors designed to reach higher temperatures by using coolants other than water. Standard Nuclear has also inked a deal with the nuclear recycling company SHINE Technologies to work on reprocessing radioactive waste into fresh fuel.
Years ago, at a lecture about the spread of Lyme disease in the New York area, I learned that opossums eat thousands of ticks every season. That information totally changed my perception of a rodent that previously creeped me out. Well, it turns out kestrels — colorful, predatory birds — serve a similar function on fruit farms. New research in the Journal of Applied Ecology suggests kestrels keep harmful pathogens off fruit by eating and scaring off small birds that carry those diseases. Orchards that housed the birds in nest boxes saw fewer cherry-eating birds than orchards without, translating to what Inside Climate News described as a 81% reduction in crop damage.

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.
