A conversation with the most interesting man on the Federal Energy Regulatory Commission.
It’s not every day that a top regulator calls into question the last few decades of policy in the area they help oversee. But that’s exactly what Mark Christie, a commissioner on the Federal Energy Regulatory Commission, the interstate power regulator, did earlier this year.
In a paper enticingly titled “It’s Time To Reconsider Single-Clearing Price Mechanisms in U.S. Energy Markets,” Christie gave a history of deregulation in the electricity markets and suggested it may have been a mistake.
While criticisms of deregulation are by no means new, that they were coming from a FERC commissioner was noteworthy — a Republican no less. While there is not yet a full-scale effort to reverse deregulation in the electricity markets, which has been going on since the 1990s, there is a rising tide of skepticism of how electricity markets do — and don’t — reward reliability, let alone the effect they have on consumer prices.
Christie’s criticisms have a conservative bent, as you’d expect from someone who was nominated by former President Donald Trump to the bipartisan commission. He is very concerned about existing generation going offline and has called activist drives against natural gas pipelines and other transportation infrastructure for the fossil-fuel-emitting power sources a “national campaign of legal warfare…[that] has prevented the construction of vitally needed natural gas transportation infrastructure.”
Since renewables have become, at times, among the world’s cheapest sources of energy and thus quite competitive in deregulated markets with fossil fuels (especially when subsidized), this kind of skepticism is a growing issue in the Republican Party, which has deep ties to oil and gas companies. The Texas state legislature, for instance, responded to Winter Storm Uri, which almost destroyed Texas’ electricity grid in 2021, with its own version of central planning: billions in low cost loans for the construction of new gas-fired power plants. Former Texas Governor Rick Perry, as secretary of energy in the Trump administration, even proposed to FERC a plan to explicitly subsidize coal and nuclear plants, citing reliability concerns. (FERC rejected it.) Some regions that didn’t embrace deregulation, like the Southeast and Southwest, also have some of the most carbon-intensive grids.
But Christie is not so much a critic of renewable resources like wind and solar, per se, as he is very focused on the benefits to the grid of ample “dispatchable” resources, i.e. power sources that can power up and down on demand.
This doesn’t have to mean uncritical acceptance of existing fossil fuel infrastructure. The idea that markets don’t reward reliability enough can help explain the poor winterization for fossil fuel generation that was so disastrous during Winter Storm Uri. And in California, the recognition that renewables alone can’t power the grid 24 hours a day has led to a massive investment in energy storage, which can help approximate the on-demand nature of natural gas or coal without the carbon pollution.
But Christie is primarily interested in the question of just how the planning is done for a system that links together electric generation and consumers. He criticized the deregulated system in much of the country where power is generated by companies separate from the utilities that ultimately sell and distribute that power to customers and where states have less of a role in overall planning, despite ultimately approving electricity rates.
Instead, these markets for power are mediated through a system where utilities pay independent generators a single price for their power at a given time that is arrived at through bidding, often in the context of sprawling multi-state regional transmission organizations like PJM Interconnection, which covers a large swath of the Midwest and Mid-Atlantic region, or the New England Independent System Operator. He says this set-up doesn’t do enough to incentivize dispatchable power, which only comes online when demand spikes, thus making the system overall less reliable, while still showing little evidence that costs have gone down for consumers.
Every year, grid operators and their regulators — including Christie — warn of reliability issues. What Christie argues is that these reliability issues may be endemic to the deregulated system.
Here is where there could be common ground between advocates for an energy transition and conservative deregulation skeptics like Christie. While the combination of deregulation and subsidies has been great for getting solar and wind from zero to around 13 percent of the nation’s utility-scale electricity generation, any truly decarbonized grid will likely require intensive government supervision and planning. Ultimately, political authorities who are guiding the grid to be less carbon-intensive will be responsible for keeping the lights on no matter how cold, warm, sunny, or windy it happens to be. And that may not be something today’s electricity “markets” are up for.
I spoke with Christie in late June about how FERC gave us the electricity market we have today, why states might be better managers than markets, and what he’s worried about this summer. Our conversation has been edited for length and clarity.
What happened to our energy markets in the 1990s and 2000s where you think things started to go wrong?
In the late ‘90s, we had this big push called deregulation. And as I pointed out in the article, it really wasn’t “deregulation” in the sense that in the ‘70s, you know, the trucking and airlines and railroads were deregulated where you remove government price regulation and you let the market set the prices. That’s not what happened. It really was just a change of the price-setting construct and the regulatory construct.
It took what had been the most common form of regulation of utilities, where utilities are considered to be natural monopolies, and said we’re going to restructure these utilities and we’re going to let the generation part compete in these regional markets.
And, you know, from an economic standpoint, okay, so far so good. But there’s been a lot of questioning as to whether there’s really true competition. Many parts of the country also just didn’t do it.
I think there’s a serious question whether that’s benefiting consumers more than the cost of service model where state regulators set the prices.
So if I’m an electricity consumer in one of the markets that’s more or less deregulated, how might reliability become an issue in my own home?
First of all, when you’re in one of these areas that are deregulated, essentially you’re paying the gas price. If it goes up, that’s what you’re going to pay. If it goes down, it looks really good.
But from the reliability standpoint, the question is whether these markets are procuring enough resources to make sure you have the power to keep your lights on 24/7. That is the big question to a consumer in a so-called deregulated state: Are these markets, which are now the main vehicle for buying generation resources, are they getting enough generation resources to make sure that your lights stay on, your heat stays on, and your air conditioning stays on?
Do you think there’s evidence that these deregulated markets are doing a worse job at that kind of procurement?
Well, let’s take, for example, PJM, which came out with an announcement in February that said they were going to lose in the next five years over 40 gigawatts. A gig is 1,000 megawatts, so that’s a lot of power, that’s a lot of generating resources. And the independent market monitor actually has told me it is closer to 50 gigawatts. So all these units are going to retire and they’re going to retire largely for economic reasons. They’re not getting sufficient compensation to stay open.
The essence of restructuring was that generating units are going to have to make their money in the market. They’re not going to get funding through what's called the “rate base,” which is the regulated, traditional cost-of-service model. They have to get it in the markets and theoretically, that sounds good.
But in reality, if they can’t get enough money to pay their cost, they’re going to retire and then you don’t have those resources. Particularly in the RTOs [regional transmission organizations, i.e. the multi-state electricity markets], you’re seeing these markets result in premature retirements of generating resources. And so, now, why is that? It’s more of a problem in the RTOS than non-RTOS because in the non-RTOS, they procure resources under the supervision of a state regulator through what’s called an integrated resource plan or IRP.
The reason I think the advantage and reliability is with the non-RTOS is that those utilities have to prove to a state regulator that their resource plan makes sense, that they’re planning to buy generating resources. Whether they’re buying wind or solar or gas, whatever, they have to go to a state regulator and say, “Here’s our plan” and then seek approval from that regulator. And if they’re shutting down units, the state regulator can say, “Wait a minute, you’re shutting down units that a few years ago you told us were needed for reliability, and now you’re telling us you want to shut them down.” So the state regulator can actually say , “No, you’re not going to shut that unit down. You’re going to keep running it.”
That’s why I think you have more accountability in the non-RTOS because the state regulators can tell the utility, “you need more resources, go build it or buy it,” or “you already have resources, you’re not going to shut them down, we’re not going to let you.”
You don’t have that in an RTO. In an RTO, it’s all done through the market. The market decides, to the extent it has a mind. You know, it’s all the result of market operations. It’s not anybody saying whether it’s a good idea or not for a certain unit to shut down.
I find it interesting that a lot of the criticism of the deregulated system — and a lot of places that are not deregulated — come from more conservative states that would generally not think of themselves as having this kind of strong state role in economic policy. What’s different about electricity? Why do you think the politics of this line up differently than it would on other issues?
I don’t know. That’s an interesting question. I haven’t even thought about it in those terms.
I think it goes back to when deregulation took place in the mid-to-late ‘90s. Other than Texas, which went all the way, the states that probably went farthest on it were in the Northeast. Part of the reason why is because they already had very high consumer prices. I think deregulation was definitely sold as a way to reduce prices to consumers. It hasn’t worked out that way.
Whereas you look at the Southeast, which never went in for deregulation. The Southeastern states, which are still non-RTO states, had relatively very low rates, so they didn’t see a problem to be fixed.
The other big trend since the 1990s and 2000s is the explosive growth of renewables, especially wind and solar. Is there something about deregulated electricity markets, the RTO system, that makes those types of resources economically more favorable than they would be under a different system?
Well, if you’re getting a very high subsidy, like wind and solar are getting, it means you can bid into the energy markets effectively at zero. So if you can bid in at zero offering, you’re virtually guaranteed to be a winner. In a non-RTO state, a state that's doing it through an integrated resource plan, the state regulator reviews the plan. That's why I think an IRP approach is better actually for implementing wind and solar because you can implement and deploy wind and solar as part of an integrated plan that includes enough balancing resources to make sure you keep the lights on.
To me an Integrated Resource Plan is a holistic process, where you can look at all the resources at your disposal: wind, solar, gas, as well as the demand side. And you can balance them all in a way that you think, “Okay, this balance is appropriate for us for the next three years, or four years, or five years.” Because you’re typically doing an IRP every three to five years anyway. And so I think it’s a good way to make sure you balance these resources.
In a market there’s no balancing. In a market it’s just winners and losers. And so wind and solar are almost always going to win because they have such massive subsidies that they’re going to get to offer in at a bid price of zero. The problem with that is they’re not going to get paid zero. They’re going to get paid the highest price [that all electricity suppliers get]. So they offer in at zero, but they get paid the highest price, which is going to be a gas price. It’s probably going to be the last gas unit to clear, that’s usually the one that’s the highest price unit. And yet because of the single clearing price mechanism, everybody gets that price. So you can offer it at zero to guarantee you clear, but then you’re going to get the highest price, usually a gas combustion turbine peaker.
Do you think we would see as much wind and solar on the grid if it weren’t for the fact that a lot of the resources are benefiting from the pricing mechanism you describe?
I don’t think you can draw that conclusion because there are non-RTO states that have what’s called a mandatory RPS, mandatory renewable portfolio standard. And so you can get there through a mandatory RPS and a cost to service model just as you can end up in a market. And actually, again, I think you can get there in a more balanced way to make sure that the reliability is not being threatened in the meantime.
To get back to what we’re talking about in the beginning, my understanding is that FERC, where you are now, played a large role in encouraging deregulation in the formation of RTOs. Is this something that your staff or other commissioners disagree with you about? How do you see the role you’re playing, where you’re doing public advocacy and reshaping this conversation around deregulation?
First of all, we always have to give the standard disclaimer, you never talk about a pending case. But FERC was really the driving force behind a lot of this deregulation. So obviously, they decided that that’s what they wanted to push, and they did. And so I think it’s appropriate as a FERC regulator to raise questions. I think raising questions about the status quo is an important thing that we do and should do. Ultimately, you advocate for what you think it ought to be and if the votes come eventually, it might take several years, but it’s important.
One of the things I try to do is, I put the consumer at the center of everything I do. It is absolutely my priority. And I think that it should be every regulator’s priority, particularly in the electric area because most consumers in America — in fact, almost all consumers in America — are captive customers. By captive. I mean, they don’t get to choose their electric supplier.
Like, where do you live, Matthew?
I live in New York City.
You don’t get to choose, right? You’re getting electricity from ConEd. And you don’t have any choice. So you’re a captive customer. And most consumers in America are captive customers. We tried this retail choice in a few states that didn’t work. You know, they’re still doing it. I’m not going to say whether it’s working or not, but I know we tried it in Virginia, and it didn’t work at all because of a lot of reasons.
I always put customers first and say, “Look, these customers are captive. We have to protect them. We have to protect the captive customers by making sure they’re not getting overcharged.” So that’s why I care about these issues. And that’s why I wrote this article. I think that customers in a lot of ways in America are not getting treated fairly. They’re getting overcharged and I think they’re not getting what they should be getting. And so I think a big part of it is some of this stuff that FERC's been pushing for the last 25 years.
Our time is running out. So I will leave with a question that is topical: It’s already been quite hot in Texas, but outside of Texas and in FERC-land, where are you concerned about reliability issues this summer?
Well, I’m concerned about everywhere. It’s not a flippant remark. I read very closely the reliability reports that we get from NERC and we have reliability challenges in many, many places. It’s not just in the RTOs. I think we have reliability challenges in the South. Fortunately, the West this year, which has been a problem the last couple of years, is actually looking pretty good because all the rain last winter — even flooding — really was great for hydropower.
I’m from California, and I think it’s the first time in my adult life that I remember stories about dams being 100 percent, if not more than 100 percent, full.
The rains and snowfall were so needed. It’s filled up reservoirs that have been really dry for years. And from an electrical standpoint, it’s been really good for hydro. So they’re looking at really good hydro availability this summer in ways they haven't been for the last several years. So the West actually, because of all the rain and the greater available of hydro, I think is in fairly good shape.
There’s a problem in California with the duck curve, the problem is still there. If you have such a high solar content, when the sun goes down, obviously the solar stops generating and so what do you do you know for the next four to five hours? Because the air conditioners are still running, it’s still hot, but that solar production has just dropped off the table. So they’ve been patching with some battery storage and some gas backup.
But I’m worried about everywhere. I watch very closely the reports that come out of the RTOs and you can’t be shutting down dispatchable resources at the rate we’re doing when you’re not replacing them one to one with wind or solar. The arithmetic doesn’t work and it’s going to catch up to us at some point.

On a new report from the Energy Institute, high-stakes legislating, and accelerating nuclear development
Current conditions: Monsoon rains hit the southwestern U.S., with flash floods in Roswell, New Mexico, and flooding in El Paso, Texas • The Forsyth Fire in Utah has spread to 9,000 acres and is only 5% contained • While temperatures are falling into the low 80s in much of the Northeast, a high of 96 degrees Fahrenheit is forecast for Washington, D.C., where Republicans in the Senate seek to finish their work on the “One Big, Beautiful Bill.”
The world used more of just about every kind of energy source in 2024, including coal, oil, gas, renewables, hydro, and nuclear, according to the annual Statistical Review of World Energy, released by the Energy Institute. Here are some of the key numbers from the report:
You can read the full report here.
Virginia Republican Jen Kiggans is a vice chair of the Conservative Climate Caucus and a signatory of several letters supporting the preservation of clean energy tax credits in the Inflation Reduction Act, including one letter she co-authored with Pennsylvania’s Brian Fitzpatrick criticizing the House reconciliation bill’s rough approach to slashing the credits. On Wednesday, however, she said on X that the Senate language “responsibly phases out certain tax credits while preserving American investment and innovation in our energy sector.”
The Senate is still pushing to have the reconciliation bill on President Trump’s desk by July 4, and is expected to work through the weekend to get it done. But as Sahil Kapur of NBC News reported Wednesday, House and Senate leaders have been attempting to hash out yet another version of the bill that could pass both chambers quickly, meaning the legislation is still very much in flux.
Shell is in early talks to acquire fellow multinational oil giant BP, the Wall Street Journal reported. While BP declined to comment to the Journal, Shell called the story “market speculation” and said that “no talks are taking place.”
BP is currently valued at $80 billion, which would make a potential tie-up the largest corporate oil deal since the Exxon Mobil merger, according to the Journal.
Both Shell and BP have walked back from commitments to and investments in decarbonization and green energy in recent months. BP said in September of last year that it would divest from its U.S. wind business, while Shell said in January that it would “pause” its investment in the U.S. offshore wind industry and took an accompanying charge of $1 billion.
The combined company would be better positioned to compete with supermajors like Exxon, which is now worth over $450 billion, while Shell and BP have a combined valuation around $285 billion.

Three Mile Island Unit 1 will restart a year early, its owner Constellation said Wednesday. When Constellation and Microsoft announced the plan to restart the nuclear facility last fall they gave a target date of 2028. More recently, however, PJM Interconnection, the interstate electricity market that includes Pennsylvania, approved a request made from the state’s governor, Josh Shapiro, to fast-track the plant’s interconnection, the company said, meaning it could open as soon as 2027.
Constellation reported “significant progress” on hiring and training new workers, with around 400 workers either hired or due to start new jobs soon. “We’re on track to make history ahead of schedule, helping America achieve energy independence, supercharge economic growth, and win the global AI race,” Constellation’s chief executive Joe Dominguez said.
The Chinese electric carmarker BYD is addressing rising inventory and lower prices by cutting back its production plans. The company “has slowed its production and expansion pace in recent months by reducing shifts at some factories in China and delaying plans to add new production lines,” Reuters reported.
The slowdown comes “as it grapples with rising inventory even after offering deep price cuts in China's cutthroat auto market,” according to the Reuters report.
In 2024, BYD beat out Tesla in annual sales, with over 4 million cars sold, for a total annual revenue over $100 billion. Tesla’s revenue was just short of $100 billion last year.
While BYD’s factories may be slowing down, it is still looking to expand, especially overseas. In April, more than 7,000 BYD battery electric cars were registered in Europe, according to Bloomberg. This more-than-doubling since last year slingshotted BYD past Tesla on the continent, where its sales have fallen by almost 50%.
“Where does the power sector go from here?” an audience member asked at our exclusive Heatmap subscriber event in New York on Wednesday, referring to a potential future without the Inflation Reduction Act. “Higher costs,” Emily Pontecorvo answered. There is one potential bright spot, however, as Robinson Meyer explained: “If I were a Democrat considering running an affordability campaign or a cost-of-living campaign in ’26 or ’28, there’s lots of openings to talk about clean energy — the policy that’s happening right now — utility rates, and energy affordability.”
The science is still out — but some of the industry’s key players are moving ahead regardless.
The ocean is by far the world’s largest carbon sink, capturing about 30% of human-caused CO2 emissions and about 90% of the excess heat energy from said emissions. For about as long as scientists have known these numbers, there’s been intrigue around engineering the ocean to absorb even more. And more recently, a few startups have gotten closer to making this a reality.
Last week, one of them got a vote of confidence from leading carbon removal registry Isometric, which for the first time validated “ocean alkalinity enhancement” credits sold by the startup Planetary — 625.6 to be exact, representing 625.6 metric tons of carbon removed. No other registry has issued credits for this type of carbon removal.
When the ocean absorbs carbon, the CO2 in the air reacts with the water to form carbonic acid, which quickly breaks down into hydrogen ions and bicarbonate. The excess hydrogen increases the acidity of the ocean, changing its chemistry to make it less effective at absorbing CO2, like a sponge that’s already damp. As levels of atmospheric CO2 increase, the ocean is getting more acidic overall, threatening marine ecosystems.
Planetary is working to make the ocean less acidic, so that it can take in more carbon. At its pilot plant in Nova Scotia, the company adds alkalizing magnesium hydroxide to wastewater after it’s been used to cool a coastal power plant and before it’s discharged back into the ocean. When the alkaline substance (which, if you remember your high school chemistry, is also known as a base) dissolves in the water, it releases hydroxide ions, which combine with and neutralize hydrogen ions. This in turn reduces local acidity and raises the ocean’s pH, thus increasing its capacity to absorb more carbon dioxide. That CO2 is then stored as a stable bicarbonate for thousands of years.
“The ocean has just got such a vast amount of capacity to store carbon within it,” Will Burt, Planetary’s vice president of science and product, told me. Because ocean alkalinity enhancement mimics a natural process, there are fewer ecosystem concerns than with some other means of ocean-based carbon removal, such as stimulating algae blooms. And unlike biomass or soil-related carbon removal methods, it has a very minimal land footprint. For this reason, Burt told me “the massiveness of the ocean is going to be the key to climate relevance” for the carbon dioxide removal industry as a whole.
But that’s no guarantee. As with any open system where carbon can flow in and out, how much carbon the ocean actually absorbs is tricky to measure and verify. The best oceanography models we have still don’t always align with observational data.
Given this, is it too soon for Planetary to issue credits? It’s just not possible right now for the startup — or anyone in the field — to quantify the exact amount of carbon that this process is removing. And while the company incorporates error bars into its calculations and crediting mechanisms, scientists simply aren’t certain about the degree of uncertainty that remains.
“I think we still have a lot of work to do to actually characterize the uncertainty bars and make ourselves confident that there aren’t unknown unknowns that we are not thinking about,” Freya Chay, a program lead at CarbonPlan, told me. The nonprofit aims to analyze the efficacy of various carbon removal pathways, and has worked with Planetary to evaluate and inform its approach to ocean alkalinity enhancement.
Planetary’s process for measurement and verification employs a combination of near field observational data and extensive ocean modeling to estimate the rate, efficiency, and permanence of carbon uptake. Close to the point where it releases the magnesium hydroxide, the company uses autonomous sensors at and below the ocean’s surface to measure pH and other variables. This real-time data then feeds into ocean models intended to simulate large-scale processes such as how alkalinity disperses and dissolves, the dynamics of CO2 absorption, and ultimately how much carbon is locked away for the long-term.
But though Planetary’s models are peer-reviewed and best in class, they have their limits. One of the largest remaining unknowns is how natural changes in ocean alkalinity feed into the whole equation — that is, it’s possible that artificially alkalizing the ocean could prevent the uptake of naturally occurring bases. If this is happening at scale, it would call into question the “enhancement” part of alkalinity enhancement.
There’s also the issue of regional and seasonal variability in the efficiency of CO2 uptake, which makes it difficult to put any hard numbers to the efficacy of this solution overall. To this end, CarbonPlan has worked with the marine carbon removal research organization [C]Worthy to develop an interactive tool that allows companies to explore how alkalinity moves through the ocean and removes carbon in various regions over time.
As Chay explained, though, not all the models agree on just how much carbon is removed by a given base in a given location at a given time. “You can characterize how different the models are from each other, but then you also have to figure out which ones best represent the real world,” she told me. “And I think we have a lot of work to do on that front.”
From Chay’s perspective, whether or not Planetary is “ready” to start selling carbon removal credits largely depends on the claims that its buyers are trying to make. One way to think about it, she told me, is to imagine how these credits would stand up in a hypothetical compliance carbon market, in which a polluter could buy a certain amount of ocean alkalinity credits that would then allow them to release an equivalent amount of emissions under a legally mandated cap.
“When I think about that, I have a very clear instinctual reaction, which is, No, we are far from ready,”Chay told me.
Of course, we don’t live in a world with a compliance carbon market, and most of Planetary’s customers thus far — Stripe, Shopify, and the larger carbon removal coalition, Frontier, that they’re members of — have refrained from making concrete claims about how their voluntary carbon removal purchases impact broader emissions goals. But another customer, British Airways, does appear to tout its purchases from Planetary and others as one of many pathways it’s pursuing to reach net zero. Much like the carbon market itself, such claims are not formally regulated.
All of this, Chay told me, makes trying to discern the most responsible way to support nascent solutions all the more “squishy.”
Matt Long, CEO and co-founder of [C]Worthy, told me that he thinks it’s both appropriate and important to start issuing credits for ocean alkalinity enhancement — while also acknowledging that “we have robust reason to believe that we can do a lot better” when it comes to assessing these removals.
For the time being, he calls Planetary’s approach to measurement “largely credible.”
“What we need to adopt is a permissive stance towards uncertainty in the early days, such that the industry can get off the ground and we can leverage commercial pilot deployments, like the one that Planetary has engaged in, as opportunities to advance the science and practice of removal quantification,” Long told me.
Indeed, for these early-stage removal technologies there are virtually no other viable paths to market beyond selling credits on the voluntary market. This, of course, is the very raison d’etre of the Frontier coalition, which was formed to help emerging CO2 removal technologies by pre-purchasing significant quantities of carbon removal. Today’s investors are banking on the hope that one day, the federal government will establish a domestic compliance market that allows companies to offset emissions by purchasing removal credits. But until then, there’s not really a pool of buyers willing to fund no-strings-attached CO2 removal.
Isometric — an early-stage startup itself — says its goal is to restore trust in the voluntary carbon market, which has a history of issuing bogus offset credits. By contrast, Isometric only issues “carbon removal” credits, which — unlike offsets — are intended to represent a permanent drawdown of CO2 from the atmosphere, which the company defines as 1,000 years or longer. Isometric’s credits also must align with the registry’s peer-reviewed carbon removal protocols, though these are often written in collaboration with startups such as Planetary that are looking to get their methodologies approved.
The initial carbon removal methods that Isometric dove into — bio-oil geological storage, biomass geological storage, direct air capture — are very measurable. But Isometric has since branched beyond the easy wins to develop protocols for potentially less permanent and more difficult to quantify carbon removal methods, including enhanced weathering, biochar production, and reforestation.
Thus, the core tension remains. Because while Isometric’s website boasts that corporations can “be confident every credit is a guaranteed tonne of carbon removal,” the way researchers like Chay and Long talk about Planetary makes it sound much more like a promising science project that’s being refined and iterated upon in the public sphere.
For his part, Burt told me he knows that Planetary’s current methodologies have room for improvement, and that being transparent about that is what will ultimately move the company forward. “I am constantly talking to oceanography forums about, Here’s how we’re doing it. We know it’s not perfect. How do we improve it?” he said.
While Planetary wouldn’t reveal its current price per ton of CO2 removed, the company told me in an emailed statement that it expects its approach “to ultimately be the lowest-cost form” of carbon removal. Burt said that today, the majority of a credit’s cost — and its embedded emissions — comes from transporting bases from the company’s current source in Spain to its pilot project in Nova Scotia. In the future, the startup plans to mitigate this by co-locating its projects and alkalinity sources, and by clustering project sites in the same area.
“You could probably have another one of these sites 2 kilometers down the coast,” he told me, referring to the Nova Scotia project. “You could do another 100,000 tonnes there, and that would not be too much for the system, because the ocean is very quickly diluted.”
The company has a long way to go before reaching that type of scale though. From the latter half of last year until now, Planetary has released about 1,100 metric tons of material into the ocean, which it says will lead to about 1,000 metric tons of carbon removal.
But as I was reminded by everyone, we’re still in the first inning of the ocean alkalinity enhancement era. For its part, [C]Worthy is now working to create the data and modeling infrastructure that startups such as Planetary will one day use to more precisely quantify their carbon removal benefits.
“We do not have the system in place that we will have. But as a community, we have to recognize the requirement for carbon removal is very large, and that the implication is that we need to be building this industry now,” Long told me.

On mercury rising, climate finance, and aviation emissions
Current conditions: Tropical Storm Andrea has become the first named Atlantic storm of 2025 • Hundreds of thousands are fleeing their homes in southwest China as heavy rains cause rivers to overflow • It’s hot and humid in New York’s Long Island City neighborhood, where last night New York City mayoral candidate Zohran Mamdani delivered his victory speech after defeating former governor and longtime party power broker Andrew Cuomo in the race’s Democratic primary.
The brutal heat dome baking the eastern half of the United States continues today. Cooler weather is in the forecast for tomorrow, but this heat wave has broken a slew of temperature records across multiple states this week:
In Washington, D.C., rail temperatures reached a blistering 135 degrees, forcing the city’s Metro to slow down train service. Meanwhile, in New Jersey, the heat sickened more than 150 people attending a high school graduation ceremony. As power demand surged, the Department of Energy issued an energy emergency in the Southeast to “help mitigate the risk of blackouts.”
As Heatmap’s Matthew Zeitlin pointed out on Tuesday, in terms of what is on the grid and what is demanded of it, this may be the easiest summer for a long time. “Demands on the grid are growing at the same time the resources powering it are changing,” Zeitlin writes. “Electricity load growth is forecast to grow several percent a year through at least the end of the decade. At the same time, aging plants reliant on oil, gas, and coal are being retired (although planned retirements are slowing down), while new resources, largely solar and batteries, are often stuck in long interconnection queues — and, when they do come online, offer unique challenges to grid operators when demand is high.”
A group of 21 Democrat-led states including New Jersey, Massachusetts, New York, Arizona, and California, is suing the Trump administration for cutting billions of dollars in federal funding, including grants related to climate change initiatives. The lawsuit says federal agencies have been “unlawfully invoking a single subclause” to cancel grants that the administration deems no longer align with its priorities. The clause in question states that federal agencies can terminate grants “pursuant to the terms and conditions of the federal award, including, to the extent authorized by law, if an award no longer effectuates the program goals or agency priorities.” The states accuse the administration of leaning on this clause for “virtually unfettered authority to withhold federal funding any time they no longer wish to support the programs for which Congress has appropriated funding.”
The rollback has gutted projects across states and nonprofits that support diversity, equity, and inclusion, as well as climate change preparation programs and research. The states say the clause is being used unlawfully, and hope a judge agrees. “These cuts are simply illegal,” said New York Attorney General Letitia James. “Congress has the power of the purse, and the president cannot cut billions of dollars of essential resources simply because he doesn’t like the programs being funded.”

A brief update from the Bonn Climate Change Conference in Germany: A group of 44 “Least Developed Countries” have called for rich countries to triple the financing goal for climate change adaptation by 2030 compared to 2022 levels. The current target sits at $40 billion a year by 2025, a number set back in 2021 at COP26. According toClimate Home News, tripling the financing goal on 2022 levels would bring in a little less than $100 billion annually. That’s far short of the $160 billion to $340 billion that the United Nations estimates will be needed by 2030. The Indian Express also reports that developing countries have “managed to force a reopening of discussions on the obligations of developed nations to ‘provide’ finance, and not just make efforts towards ‘mobilising’ financial resources, for climate action.” The issue will also be discussed at COP30 in Brazil later this year. The Bonn conference has been running since June 16 and ends tomorrow.
In the UK, aviation is now a bigger source of greenhouse gas emissions than the power sector, according to a new report from the Climate Change Committee. The independent climate advisors say that demand for leisure travel is boosting demand for international flights, and “continued emissions growth in this sector could put future targets at risk.” Meanwhile, the UK power sector has been rapidly decarbonizing, and is now the sixth largest source of emissions. (In the U.S., electricity production is the second-largest source of emissions, behind transportation.) The report also found that heat pump installations increased by 56% in 2024, and that nearly 20% of new vehicles sold were electric. UK emissions were down 50% last year compared to 1990.
The committee applauded the progress but urged more action from the government to cut electricity prices to help speed up the transition to clean technologies. “Our country is among a leading group of economies demonstrating a commitment to decarbonise society,” said Piers Forster, interim chair of the committee. “This is to be celebrated: delivering deep emissions reduction is the only way to slow global warming.”
Voters in North Carolina want Congress to leave the Inflation Reduction Act well enough alone, a new poll from Data for Progress finds. The survey, which asked North Carolina voters specifically about the clean energy and climate provisions in the bill, presented respondents with a choice between two statements: “The IRA should be repealed by Congress” and “The IRA should be kept in place by Congress.” (“Don’t know” was also an option.) The responses from voters broke down predictably along party lines, with 71% of Democrats preferring to keep the IRA in place compared to just 31% of Republicans, with half of independent voters in favor of keeping the climate law. Overall, half of North Carolina voters surveyed wanted the IRA to stick around, compared to 37% who’d rather see it go — a significant spread for a state that, prior to the passage of the climate law, was home to little in the way of clean energy development.
North Carolina now has a lot to lose with the potential repeal of the Inflation Reduction Act, as Heatmap’s Emily Pontecorvo has pointed out. The IRA brought more than 17,000 jobs to the state, along with $20 billion in investment spread out over 34 clean energy projects. Electric vehicle and charging manufacturers in particular have flocked to the state, with Toyota investing $13.9 billion in its Liberty EV battery manufacturing facility, which opened this past April.
As a fragile ceasefire between Israel and Iran takes hold, oil prices are now lower than they were before the conflict began on June 13.
