A conversation with Manjula Martin about her new book The Last Fire Season.

When Manjula Martin was growing up in Northern California in the 1980s, wildfires weren’t something she thought about much. She knew about disaster — the magnitude 6.9 Loma Prieta earthquake of 1989, which killed 63 people and injured thousands, hit when she was a teenager — but fire, she thought, was just something that happened up in the mountains in the summer.
Things are different now. In 2017, Martin left the high prices of San Francisco for the redwoods of Sonoma County. The night of their housewarming party, a firestorm swept through Santa Rosa and Sonoma and Napa counties. The next year — 5 years ago this week — the Camp Fire, the deadliest and most destructive fire in the state’s history, destroyed the town of Paradise and killed 85 people.
In her new book, The Last Fire Season (out on January 16 next year), Martin writes about the fires that swept through California in 2020, weaving her personal story with that of fire in California writ large. It’s a beautiful book, and I called her up to talk about her relationship with fire and how we can learn to live with the changing world. Our conversation has been edited for length and clarity.
The book opens in 2020, which was a year of multiple fire complexes. Was that the first time fire made itself known in the immediate vicinity of your home?
No, it wasn’t. But it was the first time that I realized that it wasn’t an anomaly.
We had horrible fires near my area in 2017. In 2018, the Camp Fire happened in Northern California, which was like a four-hour drive away, but the smoke from that fire lingered in the Bay Area for weeks. And then in 2019, the Kincade fire was a huge fire up here in Sonoma, and the entire west of the county was evacuated in basically the course of a night, including ourselves.
Then in 2020, the Lightning Complex fires happened in late August, which is what the book starts with. And that was the moment where I personally was like, “oh, this is going to keep happening.”
Before that a natural disaster to me felt like a thing that happened once and then that’s it, right? It wasn’t connected to larger things for me. But the fact is that the new wildfires that we’re having are bigger and hotter and far more destructive than the previous wildfires we’ve had, and 2020, which is probably far too late, was the year that I personally put that all together under the name of climate change. It wasn’t the first year I knew about fire, but it was the moment I realized that I was going to be living with fire for the rest of my life.
I was struck by your description of the 2020 fires and the ways that COVID complicated your experience of them. It reminded me of the concept of cascading events; it was striking to read about how your go bag was filled with these N95 masks that were there for the sake of the fires, but also, of course, turned out to have utility for this other thing that you’re dealing with at the same time.
That was one of the reasons why I chose to center the book around 2020. I think that was a moment where it became clear for a lot of people that disasters don’t take their turn. When it was happening, I felt it was a historic moment.
You named your book The Last Fire Season. But, of course, it wasn’t the last.
Unfortunately not. The book began as an essay, and since I was writing it in 2021 I thought I was writing about the last fire season I had experienced. But then I realized that it was actually a really great title for a book. It’s pretty commonly acknowledged now that in the North American West, fire season isn’t really a thing anymore. Now fire authorities talk about having a fire year.
That is directly linked to the changing of the weather and the climate. But for me, the deeper meaning of it is this idea that fire being seasonal also sort of implies that it’s temporary, and that it’s going to go away. But really it’s not seasonal, it’s part of this land. And we’re going to be living with it forever.
There’s a point in your book where you write that the California ecosystem was fire-adapted, but also that fire is changing. What do you mean by that?
Since time immemorial, California’s ecosystems — from oak woodlands to redwood forests to grasslands and chaparral — evolved with fire as part of their natural cycle. Fire is actually something that helps the cycle of the landscape reset and continue.
And this was something that Indigenous people knew and really sort of harnessed and used in the way that they tended the lands. But the genocide of Indigenous people in California really sort of stopped that cycle, as is the case with colonialism in most places.
Right, you have a chapter about the Indigenous history of fire in California and the suppression of fire both through violence against Indigenous communities and also a long history of policies against fire.
Yeah, the colonial policies of managing the land in California had been what they call ”total fire exclusion,” which is basically the idea that all fire is bad and we need to extinguish fires right away. There was a policy in place called the 10 AM policy that actually said every new forest fire needs to be extinguished by 10 AM the next morning. And, you know, there are a lot of reasons why that happened, including profits and fear and prioritizing human habitat and recreation over the landscape. But the result is that the landscapes here are actually neglected at this point, 150 years after colonization.
You wrote at one point about going to prescribed burns and there was a section that really stood out to me:
Fire is exuberant. It’s joyous. It dances. I can see why people joke that all firefighters are secret pyros. It’s so much fun.
I fully relate to this feeling. Has going to prescribed burns changed your own relationship with fire?
Good fire and cultural fire, which is generally the term we use when we’re talking about Indigenous use of fire, have radically changed my feelings about fire. Humans have evolved with fire, and the more I engage with fire, the more I learn about it, the more I understand its role in both the land and the history of this place, the less afraid I feel.
You write about your own experience with getting a hysterectomy and how that affected your life afterwards, and I thought that was an interesting choice. You could have written a book that was just about fire, and we could have never learned about your hysterectomy. But you chose to include it. Can you tell me a little bit about how that came to happen?
I could have written a straight journalistic look at wildfire right now or at the 2020 fire season specifically. And that was something I toyed with. But I ultimately realized, in thinking about this idea of cascading disasters, that they’re all happening while people are living their lives. Climate change, wars, economic ruin are all happening on top of whatever else is going on in your life. So I thought this part of my life was worth including.
The hysterectomy, and many associated health crises, led me to having chronic pain. And one of the only things that helped me with that was gardening. For me, the physical act of literally touching the land, being in this dialogue with the environment and the ecosystem around me, was the thing that helped me recover from this health crisis. I wasn’t quite well. And more importantly, nature wasn’t quite well. And gardening in this environment is what really made it click for me that this environment is going through a crisis as well.
That garden was partly how you knew about the oncoming fires in 2020, right?
Yeah, when the Lightning Complex fires started, I was out in my garden watering the roses. I saw this little black object on the ground, and when I leaned down and picked it up I saw it was a leaf of a California bay laurel tree. And it was burned black, but it was still whole. It had been blown on the wind and landed in my garden. It was sort of like a messenger, telling me that a few miles away these trees were burning.
Bay trees are a natural part of the forest understory here, but they are highly flammable. They’re basically made of oil, and they serve as what’s called a ladder fuel; if fire gets in that tree, it will shoot up it and then can get into the crowns of taller trees like redwoods or oaks that would normally be more fire resistant. It’s literally a fire spreader. Anyone who lives in the area will tell you that when there’s a fire nearby it rains burnt leaves.
Parts of the book are unexpectedly written in the past tense. You write, for example, that “Northern California was a very large place,” but the depictions of events in the past or future are written in the present tense. Was that intentional? Did you mean to contract the idea of Northern California?
I absolutely did. The convention in nonfiction is to write events in the past tense, but to phrase facts, or things that are still true, in the present tense. I felt like it was important to acknowledge that the things we take as granted, these truths about the way the environment works, might not always remain that way. It was also partly a pragmatic decision, because I didn’t know what would happen before the book came out. What if my house burned down before that, or if I have to move? Things are just so chaotic right now.
The other time I break with convention is when I write about Indigenous nations and Indigenous management practices. I intentionally used the present tense there as a way to push back against the trope of a lot of non-Indigenous writers portraying Indigenous people and worldviews as extinct when in fact they’re very, very alive.
Throughout the book you’re constantly talking to your partner about whether to stay in your home or move away to a “safer” area. I think it can be really hard for people who don’t live in areas under threat to grasp just how hard the concept of migrating really is.
Right, that’s such a common binary: to stay or go. And the reality is actually a lot messier. I’m fortunate to even have the choice of whether to stay or go; I am a person who has a lot of different privileges. I have resources, I have friends, I’m educated, I’m white.
Most people don’t willingly leave their homes unless things are really bad. But it’s never really all bad: Sometimes there’s extreme weather and disasters, and then there isn’t. It’s up and down. There’s a lot of talk around what the perfect solution is, where the safe places are. And the truth is that nowhere is safe because of climate change.
For me, the point of living at this moment on this planet is that it’s messy. It’s full of grief, it’s full of joy and beauty, and it’s also dangerous. There may be a time when I leave this place, for a variety of reasons. But I think the idea that you can run away from climate change is false.
Something I’ve learned a lot from talking with people who are deeply connected to the land here and who work with fire is that you have a responsibility to the place where you live. If I love this place so much, what do I owe it? The idea of tending a place for its overall health, not just for my personal survival, is very powerful.
Right, at one point you write about you and your partner thinking about doing prescribed burns in the woods near you to help reduce the risk of more fires.
We have thought a lot about the idea of reintroducing good fire where we live. Our neighborhood has been getting together and doing work days where we clear fuels from the forest floor together. And it’s really proof of how much work is needed, because you can clear brush and cut dead limbs off trees for a day with a group of 15 people, and then you look at this tiny quarter acre that you’ve worked on, and it still needs so much more work.
Stewardship is a constant act.
Absolutely. And it might not be perfect, and honestly it might not make a difference. These woods might still burn. But if and when they do burn, they are going to be healthier afterwards because the fire is going to be healthier.

Risk-averse but deep-pocked institutional investors join the party.
When the Fusion Industry Association surveyed the sector earlier this month, it found that the industry’s 56 active companies had collectively raised more than $14.2 billion over the past five years. But an ever-larger share of that money is ending up in the hands of one startup: Commonwealth Fusion Systems.
With its latest $1 billion funding round, announced today, the MIT spinout now accounts for nearly 30% of all capital in the industry. The new financing, led by a wave of institutional investors entering the sector for the first time, will support construction of the company’s first commercial power plant in Chesterfield County, Virginia, which CEO Bob Mumgaard says is on track to come online in the early 2030s.
In a media briefing, Mumgaard noted that this latest raise marks “the largest single funding round among fusion energy companies since our last large round of $1.8 billion in 2021.” It brings the total capital raised by CFS to an even $4 billion as the company races to complete construction of SPARC, its demo reactor. If all goes according to plan, it should begin operating sometime next year, proving out the physics and engineering approach underpinning ARC, the planned commercial plant.
The new financing deviates from the typical venture capital round, as it brings in a broad but unnamed mix of “large pension funds, sovereign wealth funds, infrastructure funds doing project finance, and industrial corporates.” These risk-averse investors would typically steer clear of expensive, first-of-a-kind facilities, demonstrating the degree to which CFS has succeeded in building confidence in an industry long critiqued for overpromising and underdelivering.
The company credits the trust it built to its extensive peer-reviewed research as well as its decision to build a tokamak — widely regarded as the most mature fusion reactor design. “I don’t think there’s any other company that’s been as transparent and open with their physics and how it actually works,” Katie Rae, CEO and managing partner at Engine Ventures, told me. Rae has participated in every one of CFS’s funding rounds, and while she says her firm has evaluated virtually every startup in the sector, the company remains its only fusion investment.
But even flush with institutional capital, Mumgaard is clear that the company will need billions more to fully finance ARC and the numerous reactors to follow. It’s unclear where exactly that money will come from, though he’s pushing for government involvement. Alongside the Fusion Industry Association, Mumgaard is advocating for a one-time, roughly $10 billion federal infusion of cash into the broader industry to expand public-private partnerships, build shared research infrastructure, and help finance first-of-a-kind plants in an effort to keep pace with China’s rapidly growing fusion program.
According to reporting from Politico, a Department of Energy official told CFS and other fusion companies that such a level of federal funding is “unrealistic in this environment.” But though insiders argue it’s what the industry needs to scale, Rae says CFS doesn’t depend on it. “I think it is the right kind of investment to make, but we didn’t count on it from an investor perspective,” she told me.
One obvious alternative is the public markets. The IPO window for climate tech has reopened, with geothermal giant Fervo and nuclear fission startup X-energy both completing successful public offerings in recent months. SPACs have also made a comeback, as numerous nuclear companies are opting for this faster, though riskier, path to the public markets. But CFS’s newly appointed CFO, Lorence Kim, said during the briefing that this latest round proves “that the private markets have a lot of capital to deploy toward our mission.” Whether an IPO is in the company’s near future remains an open question, though he cautioned against interpreting his hiring as any indication of “IPO prep in a specific way.”
For what it’s worth though, Kim has taken another high-profile, pre-revenue startup public before: Moderna. As CFO from 2014 to 2020, he helped the company scale its mRNA platform and lead its blockbuster $600 million IPO in late 2018 — the largest ever in the biotech industry at the time. Notably, this all happened before Moderna had an approved product or the Covid pandemic made its signature vaccine a household name, similar to where Commonwealth finds itself today.
“Moderna was in this moment in time where the science worked, and the strategy was focused on execution and scale and deploying capital in a way that could enable real impact on the world,” Kim explained. CFS is now at the same juncture, he said. “And so in the same way that Moderna industrialized mRNA and made it inevitable and made it ubiquitous, it was really clear to me that CFS could do the same for fusion.”
Of course, CFS is not alone in its confidence — other fusion companies are equally bullish on their own approach. Take Inertia Enterprises, a Lawrence Livermore National Laboratory spinout, which last week unveiled its own commercial roadmap for a laser-driven fusion reactor. The company emphasized it’s the only one to have definitively demonstrated the viability of its underlying physics in a real-world experiment, rather than through theoretical work or simulations.
Or take Helion, which has raised $1.5 billion and secured a highly ambitious power purchase agreement with Microsoft to supply electricity to the tech giant by 2028. Or Pacific Fusion, which netted a staggering $900 million Series A to be doled out in milestone-based tranches. There are dozens of others — many with hundreds of millions in funding — pursuing a range of approaches that some of the field’s brightest minds consider technically feasible.
But when I mused to Rae about how exciting it is that institutional investors now appear willing to back an industry once viewed as bordering on science fiction, she was quick to correct me.
“They’re willing to bet on Commonwealth Fusion — that’s what you mean.”
At least one hyperscaler’s big bets seem to be paying off.
This is an edition of Heatmap Daily, an evening review of the day’s news written by our executive editor. Sign up for it here.
Good evening. Let’s start with the news. Meta and Microsoft released their most recent quarterly earnings this evening, and Wall Street was watching to figure out if their enormous AI spending plans are paying off. We were watching because those proposals are shaping one of the most important energy stories today: the data center boom and the sharp return of electricity demand.
The returns were … mixed. Meta missed analysts’ estimates, and its profit fell 14% from the same quarter a year earlier. It increased the lower bound of how much it plans to spend on capital expenditures such as data centers this year, from $125 billion to $130 billion, but left the upper bound of $145 billion unchanged.
Microsoft, meanwhile, said its AI investments are starting to pay off. Revenue at its cloud business, which uses its data center space, increased by 43%, more than analysts expected. It spent $41 billion on capital expenses in the three months ending in June.
Meta’s stock was down 7% in after-hours trading, while Microsoft is up 8%. When Heatmap surveyed climate insiders last year, they ranked Microsoft as among the most decarbonization-friendly hyperscaler and Meta as among the worst.
Permitting odds up — thanks to Shift Key?
I do not regularly follow such things, but this afternoon I was told that the Kalshi market for “Will permitting reform become law this year?” surged to 77% today after trading for days around 50%:
I have no idea why it budged today, but perhaps what moved the market was our new episode of the Shift Key podcast (Apple, Spotify). On today’s show, I spoke with Daniel Palken, a former Capitol Hill policy staffer now at Arnold Ventures, about the current state of permitting reform negotiations in Congress. While we don’t know the exact shape of a deal yet, permitting reform is likely to be the biggest new policy for clean energy that we could get by the end of the year.
Daniel is a fantastic guide to the negotiations, and if you’re curious about the policy at all, I recommend that you listen. Here are few of my takeaways from the conversation:
1. A permitting reform deal will probably have six buckets.
They are (1) changes to the National Environmental Policy Act and the judicial review process that environmental studies face after completion; (2) reforms to the transmission process; (3) changes to the Clean Water Act; (4) a deal to make it harder for presidents to yank permits from approved projects; (5) changes to the National Historic Preservation Act, and (6) “everything else,” a grab bag of smaller fixes including to geothermal energy.
2. Wonky committee politics are shaping the deal.
The National Historic Preservation Act, for instance, is an archeological law that hasn’t been in the mix for previous reform proposals. It’s up for discussion now because Senator Mike Lee of Utah chairs the Senate Energy and Natural Resources Committee — and the NHPA is the major environmental bill under his jurisdiction. Likewise, observers think that a permitting deal has a much better shot of passing during this Congress (as compared to next year) because of an expected series of changes to committee chairs.
3. It’s way, way better to hook data centers to the power grid than run them off behind-the-meter power plants — even if they run off 100% natural gas.
Any permitting reform proposal will seek to expand the transmission system. That could have big benefits for the emissions intensity of data centers. Why? I’ll let Daniel explain:
If you look at the data centers that are hooking up off grid — when they’re not using repurposed jet engines, they’re using 20% thermally efficient gas plants. Whereas if you’re hooked up to the grid, there’s really two types of gas plants that live on the grid. There’s like 60% efficient combined-cycle gas turbines, which are most of the gas power that’s generated, and then there’s peaker [plants], which have low efficiency, but are run at capacity factors of like 5% — so from an emissions perspective, they don’t matter all that much.
So even if solar and wind didn’t exist at all, and nuclear didn’t exist, and hydro didn’t exist, it would still be a much, much cleaner option [to connect data centers to the power grid]. Like we’re talking factors of three in efficiency to connect your data center to the grid if it was purely powered by gas, which is, I think, an important point to understand.
I thought that was an interesting point, and while I’d seen some of those ideas in isolation, I’d never seen them laid out in one place. (And even if grid-scale gas plants are much more efficient than behind-the-meter plants, it’s still even better to power data centers with solar, batteries, and other clean firm power plants — which is also easier when they’re hooked up to the grid.)
I’ll stop glossing the episode and just link to it one more time. Thanks for reading.
On nuclear waste, a Nevada solar farm, and lithium-harvesting nanorobots
Current conditions: France just ordered 4,000 more people to evacuate the wildfires that have now displaced a third of a million people across southwestern Europe • The heat dome in the southwestern United States is driving temperatures in Phoenix up to 113 degrees Fahrenheit by the end of the week • Temperatures in Tuscany are topping 100 degrees this week as Europe’s latest heat wave takes hold.
Just yesterday, I told you that China’s dominance over the manufacturing of the inverters needed to patch solar panels and batteries onto the grid and into data centers had peaked two years ago as Europe’s factories began booming. Hours after the newsletter landed in your inbox, the Trump administration unveiled plans to ban imports of Chinese power inverters in a bid to protect the U.S. buildout of artificial intelligence from sabotage and competition. On Tuesday, the Federal Communications Commission told CNBC its new restrictions aimed to safeguard the AI supply chain “from Chinese threats of disruption, data threat, and cyber attacks.” The measures also bar imports of Chinese-made humanoid and quadruped robots. As you may recall, Reuters broke news in May 2025 that the U.S. government had discovered rogue communications devices in the Chinese-made inverters. The story came out just a month after a frequency problem that stemmed from Spain’s struggle to sufficiently patch all of its solar generation on the grid triggered a blackout across Iberia, highlighting the sort of scenario a compromised “killswitch” device could set off in a bid to attack energy systems.
The ban is good news for America’s beleaguered solar manufacturing industry, which the Trump administration has championed with tariffs but hobbled by axing key federal tax credits that included bonuses for projects using domestically produced panels. T1 Energy, shares of which nosedived this week after the latest quarterly earnings showed losses far outpacing revenue, just spent another $135 million on patents from a rival in Singapore in a bid to vertically integrate production of a more efficient type of photovoltaic technology. Tesla, meanwhile, is promising to “multiply” American solar production by “an order of magnitude.” Yet Elon Musk’s behemoth is cutting long-term deals to buy other people’s solar power. The company just inked an agreement with a KKR-backed solar and battery project in Arizona to buy 90% of its output.

Reasonable people debate just how much electricity is needed to satisfy the demands of the data center boom — and the bears are likely to get a boost amid this week’s selloff of AI stocks. But the latest projections from the Rhodium Group forecast U.S. electricity demand growth to accelerate over the next 15 years, “growing faster than it has since the turn of the century.” Data centers will account for between 62% and 77% of the growth in 2030, and between 59% and 66% in 2040, ultimately reaching 17% of total electricity demand that year. Electric vehicles will make up the second-largest source of new demand growth in the low- and mid-emissions scenarios the consultancy outlined through 2040. In the high-emissions scenario, heavy industry will account for a quarter of the demand growth between 2025 and 2040. Overall, the findings show divergent pathways in the 2030s. By 2040, the U.S. will either reduce its greenhouse gas emissions by 41% below 2005 levels — or just 27%. Across all three scenarios, the “historic influx of renewables” coming online between now and 2030 keeps emissions declining. After 2030, however, the grid’s trajectory either continues to deploy nearly 53 gigawatts of renewables per year through 2040 in a low-emissions scenario or drops to 3 gigawatts per year in a high-emissions scenario where cheap natural gas dominates.
For months now, the Greenhouse Gas Protocol, the nonprofit behind a voluntary but widely used corporate standard for carbon accounting rules, has been revising its approach. Last year, my colleague Emily Pontecorvo explained the stakes of the revision process as an “obscure philosophical battle that could reshape the clean energy economy. In April, she broke news from whistleblowers that the changes underway were drumming up controversy. This morning she’s out with a new story on Greenhouse Gas Protocol’s plans to marry its standard to those by the International Organization for Standardization. The short of it is this: the changes are getting a lot of pushback, and credibility of the forthcoming new standard remains an open question.

For decades, the U.S. plan to deal with nuclear waste has focused on building a highly controversial repository in the Nevada desert. But that effort, as I explained yesterday, was put on indefinite hiatus in 2010 when the Obama administration canceled funding on behalf of then-Senate Majority Leader Harry Reid, a Nevada Democrat. In the meantime, states such as Texas and New Mexico have demonstrated that both Republican and Democratic governments are still willing to fight efforts to build intermediate-term storage facilities for nuclear waste in their states. On Tuesday, five states officially stepped up and made bids to host what the Department of Energy is calling its Nuclear Lifecycle Innovation Campuses, which will house startups that recycle spent nuclear waste into fresh fuel and medical isotopes. The Energy Department named Utah, Tennessee, Oklahoma, Louisiana, and Idaho as finalists for the facilities. “I’m pleased to announce that after reviewing 28 applications from 26 states, the Energy Department has selected five initial contenders to further explore building Nuclear Lifecycle Innovation Campuses,” Secretary of Energy Chris Wright said in a statement. “These campuses will be massive generators of economic growth, create thousands of high-paying jobs, and be crucial to unleashing America’s nuclear renaissance.”
Just last week, the Energy Department opened the door to nuclear projects sited on floating offshore platforms. It’s a novel idea for the U.S., but Russia launched its Akademik Lomonosov, a floating nuclear station, in 2019 in what is widely recognized as the world’s first real small modular reactor and only operating non-land nuclear plant. A new peer-reviewed study the World Nuclear Association conducted on the Rosatom-owned plant ranked it “on par with Russia’s top units,” World Nuclear News reported.
Trump’s permitting freeze for renewables projects started to thaw for solar in particular earlier this year as the administration faced mounting pressure to stop thwarting the fastest-growing source of power in a country increasingly starved for new and swiftly available sources of electricity. The easing, as my colleague Jael Holzman wrote, was also part of a legal strategy. Regardless of the reasoning, the thaw is continuing — and not just because of the literal heat dome pushing temperatures in the Southwest into the triple digits. On Tuesday, the Department of the Interior’s Bureau of Land Management announced plans to advance a solar project in the Nevada desert. The Mosey solar farm, which would produce enough power at maximum output for 200,000 homes, is now under evaluation at the agency’s Nevada office, the agency notified the Federal Register. The regulator plans to conduct an environmental analysis and a resource management plan tweak needed for a project in a utility corridor. E&E News credited the administration’s shift on this particular project to lobbying by the state’s Republican governor, Joe Lombardo.
The project is part of developer Clearway’s larger efforts in Nevada. Separately, the company has volunteered to scrap one of its other solar projects in favor of building a gas plant, Jael reported this week.
Yesterday, I told you the board of PJM Interconnection had scheduled an emergency auction to drum up 7 gigawatts of additional capacity to supply the electricity demand from data centers starting in 2028. It’s just one incremental way the nation’s largest grid system is “lurching toward reforms,” as my colleague Matthew Zeitlin wrote. It’s also inching toward more actual power infrastructure. On Wednesday, the developer Eolian Energy started construction on Flint Grid, a 1 gigawatt-hour storage project outside Columbus, Ohio. Located near a hub of data center and industrial power users, the Flint Grid project is “the first large-scale battery energy storage system to qualify for the PJM capacity market.” If it comes online in spring 2027 as promised on the project’s new website, it will represent more than half the new battery storage capacity in PJM’s line up for 2027 to 2028. The project is also the first grid-scale battery project permitted by the Ohio Power Siting Board and the largest in the PJM territory to date.
“There’s growing consternation about how the US can rapidly scale infrastructure to support America’s growing electricity demand, but not nearly enough conversation about how to use existing technology to unlock the wasted capacity that already exists on the grid,” Eolian founder and CEO Aaron Zubaty said in a statement. “This project requires hundreds of millions of dollars to construct, and we committed the necessary capital and resources years before today’s demand forecasts became headline news. As policymakers consider changes to competitive electricity markets, it’s critical that they avoid undermining the long-term investments already.”
Lithium production typically involves either mining hard rocks or extracting salts through brines. Both are water intensive processes with considerable environmental tolls. Scientists at Texas A&M University are now developing a new approach involving the deployment of tiny, fish-like swimming nanorobots that capture lithium ions from seawater. Backed by a $1 million Energy Department grant, it’s among more than a dozen projects the agency is supporting in a bid to bolster domestic critical mineral supplies. “Unlike traditional mining that digs up land or pumps brine from underground and requires massive amounts of energy, these autonomous micro/nanorobots move freely through seawater to harvest lithium with virtually zero infrastructure footprint,” Jingjing Qiu, one of the mechanical engineers leading the research, said in a statement.
