The small hydrogen plant at the Port of Stockton illustrates a key challenge for the energy transition.
Officials at the Port of Stockton, an inland port in the Central Valley of California, were facing a problem. Under pressure from California regulators to convert all port vehicles to zero-emissions models over the next decade or so, they had made some progress, but had hit a wall.
“Right now we only have one tool, and that is to electrify everything,” Jeff Wingfield, the port’s deputy director, told me. The Port of Stockton has actually been something of a national leader in electrifying its vehicles, having converted about 40% of its cargo-handling equipment from diesel-powered to battery-electric machines to date. But there aren’t electric alternatives available for everything yet, and the electric machines they’ve purchased have come with challenges. Sensors have malfunctioned due to colder weather or moisture in the air. Maintenance can’t be done by just any mechanic; the equipment is computerized and requires knowledge of the underlying code. “We’ve had a lot of downtime with the equipment unnecessarily. And so when we’re trying to sell that culture change, you know, these things can set back the mindset and just the overall momentum,” said Wingfield.
The port also needs its tenant companies to make the switch, but according to Wingfield, they are hesitant to invest in the electric truck models available today. They’re more interested in hydrogen fuel-cell trucks, he said, which are also zero-emissions, and there’s even a vendor selling them right down the street. The problem was there was no source of hydrogen within an hour and a half of the port.
It was these conditions that got Wingfield and his colleagues excited about BayoTech, a company that wanted to build a new hydrogen plant there — even though BayoTech was going to make hydrogen from methane, the main component of natural gas, in a carbon emissions-intensive process. Hydrogen fuel-cell powered trucks don’t release any of the carbon or toxic pollutants that diesel trucks release, but the process of making the hydrogen fuel can still be dirty.
While the port was considering BayoTech’s proposal, California leadership was committing the state to building out a climate-friendly hydrogen industry. In July, the Biden administration awarded California $1.2 billion for a $12.6 billion plan to build new, zero-emissions hydrogen supply chains. “California is revolutionizing how a major world economy can clean up its biggest industries,” Governor Gavin Newsom said. “We’re going to use clean, renewable hydrogen to power our ports and public transportation – getting people and goods where they need to go, just without the local air pollution.”
Nonetheless, the port approved the fossil fuel-based hydrogen plant in August.
The case illustrates the complexities of this moment in the energy transition. At its center is a question: Should we gamble with higher emissions today on the premise that it could help lower emissions in the future? It’s a gamble that many climate advocates, guided by warnings from scientists about the consequences of continued fossil fuel use, fear will do more harm than good.
The port, which was the lead agency for the environmental review process, estimated that if all of the fuel BayoTech produced was used as a replacement for diesel, it would result in a net decrease in emissions of 4,317 metric tons of CO2 per year, which is like taking 1,000 cars off the road. Still, the plant will emit about 18 kilograms of carbon for every kilogram of hydrogen it produces — more than four times higher than the Department of Energy’s standard for “clean” hydrogen.
Climate and environmental groups in Stockton oppose the project. They’ve raised a number of concerns about it and the conditions under which it was approved, but one is the missed opportunity. “At a time when incentives are lining up for cleaner production methods,” Davis Harper, the carbon and energy program manager at the local group Restore the Delta, told me, “and at a time when the state in particular is really trying to transition away from methane, to approve a new steam methane reforming project in a community that’s already suffering from so many cumulative impacts of industrial pollution — it’s a major regression.”
Between operations at the port, highways, warehouses, and other industrial activity, Stockton ranks in the 96th percentile for pollution burden in California, and in the 100th percentile for cases of asthma. In addition to carbon dioxide, the BayoTech plant will release nitrogen oxides, carbon monoxide, and particulate matter. Harper and other local advocates want the community to have more of a say in shaping regional economic development and defining what its hydrogen future looks like. “I think it puts a stain on what the opportunity for hydrogen might be in the community,” he said.
But Wingfield told me it wasn’t an either/or scenario. “I mean, nobody was approaching us with a green hydrogen project,” he said. Even if someone was, Wingfield said green hydrogen was still too expensive and that no one would buy it. The port is supporting state-wide efforts to develop a more sustainable supply of hydrogen in the future, he said, “but it is slow, and for us, we need something now.”
There’s a chicken-and-egg challenge to getting a clean hydrogen economy going. In addition to a new supply of fuel, it will require investments in new vehicles, fueling stations, and modes of delivering the gas — and that’s just for trucking. Decarbonization experts also see potential to use hydrogen for cargo ships, steelmaking, and aviation. “I agree, you know, don’t wait around for the green projects that are being planned to come online,” Lew Fulton, the director of the energy futures research program at the U.C. Davis Institute of Transportation Studies, told me. “There’s a whole bunch of things we need to learn by doing. And so from that point of view, you could argue, well, in the first few years, it doesn’t matter that much what kind of hydrogen it is.”
When I asked Catharine Reid, BayoTech’s chief marketing officer, what brought the company to Stockton, she told me California is a key market and the San Joaquin Valley is currently a dead-zone for the fuel. The Regional Transit District recently purchased five new fuel-cell buses, but to fuel them, it will have to truck in hydrogen from other parts of the state. BayoTech’s business model is designed to address this kind of local need. The company builds small, modular plants and sites them as close to the point of consumption as possible to avoid the cost and emissions associated with transporting the fuel. The project in Stockton will produce just 2 tons of hydrogen per day, or enough to fill the tanks of about 50 trucks. By contrast, the average hydrogen plant in California, which mostly delivers the gas to oil refineries and fertilizer plants, produces closer to 200 tons per day. “We anticipate that that demand will be snapped up quickly,” said Reid.
The port approved the plant using an abbreviated environmental review process — another aspect that troubled the advocates I spoke to — which required BayoTech to mitigate some of its most significant impacts. To reduce pollution, the company will install equipment that cuts the plant’s nitrogen oxide emissions. It has also committed to using zero-emissions vehicles for at least 50% of deliveries. But the biggest pollutant that will come out of the plant is carbon dioxide — just over 12,000 metric tons of it per year. That’s not much compared to the average hydrogen plant. The smallest existing hydrogen plant in California, Air Products’ Sacramento facility, has the capacity to produce more than twice as much hydrogen as BayoTech will, but emitted nearly four times as much carbon in 2021, according to state data. One of BayoTech’s selling points is its technology’s efficiency.
The company has also committed to developing a community benefits plan, which is still in the works, though BayoTech has already signed an agreement to use local union labor and committed to donate $200,000 over the next four years to the community.
Part of BayoTech’s agreement with the port is that it will lower its emissions by purchasing carbon credits from producers of so-called “renewable natural gas,” or RNG, which can mean methane captured from landfills or from cow manure pits. It’s considered low-carbon because the methane would otherwise be released into the atmosphere, where it would warm the planet far more than carbon dioxide. In theory, credit sales help finance systems to capture the gas and use it for energy instead.
I asked Reid why, when there was so much focus on and funding available for clean hydrogen, like California’s $12.6 billion initiative and lucrative new federal tax credits, the company was investing in the fossil-fueled kind. She suggested that once the federal tax credit rules are finalized, the plant may in fact be eligible for the subsidies. That’s because the guidelines might allow hydrogen plants that buy RNG credits to qualify. “It’s a well established system that’s validated,” Reid said of the credits, “and the environmental benefits are there.”
It’s true that this system of RNG credits is well-established. It’s already written into California climate policy. The state has a low carbon fuel standard designed to drive down the average carbon intensity of transportation fuels over time. When it comes to calculating the carbon intensity of hydrogen for the regulations, there’s a workaround. If the hydrogen is made from natural gas, but the supplier purchases RNG credits, they can report their hydrogen as having a very low or even negative carbon intensity.
But the environmental benefits of these credits are the subject of much debate. Notably, fuel producers can buy credits from all over the country, and they don’t have to prove that their purchase had an additional effect on emissions beyond what might have happened otherwise. Though these credits may have some environmental benefit, they are certainly not causing carbon to be removed from the atmosphere, as implied by a negative carbon intensity. In an op-ed for Heatmap, scholars Emily Grubert and Danny Cullenward urged the Treasury Department not to adopt this same carbon accounting scheme for the federal tax credit, writing that it “would undermine the tax credit’s entire purpose.” They estimate that a fossil hydrogen project could qualify as zero-emissions by offsetting just 25% of its natural gas use. This could make it much harder for truly green hydrogen — like the kind made from electricity and water — to compete.
Interestingly, California’s new $12.6 billion clean hydrogen initiative appears to renounce RNG credits. A frequently asked questions page for the plan says that it “will not include the use of plastics, dairy biogas, or fossil methane paired with biomethane credits.”
Still, the California Governor’s Office of Business and Economic Development praised the BayoTech project in public comments, writing that it would “contribute to achieving California’s ambitious climate and pollution reduction goals.”
The letter seemed to be mistaken about what it was supporting, however, noting that the facility would “utilize woody biomass, helping to address two needs — utilization of a waste stream and production of renewable hydrogen.” When I reached out to the governor’s office, spokesperson Willie Rudman told me the reference to woody biomass was an accident, “resulting from a mix-up with another project.” Still, the office supports the project, he said, due to “commitments made by the developer to utilize renewable natural gas as the feedstock, which can be transported to the production facility via existing natural gas pipelines.”
When I noted that this, too, was a mix-up, and that BayoTech would be buying RNG credits, not using the fuel directly, Rudman responded that this was a cost-effective and perfectly acceptable practice under California’s low-carbon fuel standard.
If you view BayoTech’s plant as a bridge to get the hydrogen economy underway, Ethan Elkind, director of the climate program at the University of California, Berkeley’s Center for Law, Energy and the Environment, told me, it’s important to know how to get to the other side. “Is this just a lifeline for the oil and gas industry, to give them another product that they can sell, which those profits then go back into drilling more oil and gas?” He said he wasn’t categorically opposed to the idea of using natural gas to produce hydrogen for now, as long as there were built-in mechanisms to convert the facility to zero-emissions down the line.
Wingfield of the Port of Stockton asserted that BayoTech’s plant would become cleaner over time, but the port has no such commitment in writing, and it’s also not entirely clear how. BayoTech’s Reid was not sure whether the Stockton plant would find a local source of RNG. She said the company was looking, but that it was rare to find alignment between BayoTech’s business model — putting hydrogen production very close to demand — and RNG suppliers. The only other route to cleaner production, other than completely replacing the plant with one that runs on electricity, would be to install carbon capture equipment. But Reid said the amount of carbon the plant produces will be so small that it may not justify the expense. “We continue to talk to players in the industry and evaluate what they’re bringing out commercially to see if there’s a match with our production units,” she said.
Construction on the plant will begin in a few months, Reid told me, and won’t take long. BayoTech expects to be delivering hydrogen in 2025.

Even as Iran retaliated against U.S. airstrikes, prices have stayed calm.
Oil prices have stayed stable so far following the U.S. strikes on Iranian nuclear facilities over the weekend, and President Donald Trump wants to keep it that way.
In two consecutive posts on Truth Social Monday morning, the president wrote “To The Department of Energy: DRILL, BABY, DRILL!!! And I mean NOW!!!” and “EVERYONE, KEEP OIL PRICES DOWN. I’M WATCHING! YOU’RE PLAYING RIGHT INTO THE HANDS OF THE ENEMY. DON’T DO IT!”
While Iran, of course, does not yet have an actual nuclear weapon, it does have a kind of “nuclear option” to retaliate: closing off the Strait of Hormuz, which separates the oil-rich countries like Qatar, Bahrain, Kuwait, and Iraq (and Iran’s own largest ports) from the Indian Ocean, and by extension all of global shipping. Iran’s parliament approved closing off the strait, but any real effort to do so would have to come from Iran’s most senior leadership, which has not so far seemed inclined to torpedo its own economy.
Markets, at least so far, do not see much more risk today than they did before the U.S. airstrikes. West Texas Intermediate oil price benchmark sat at just over $74 a barrel Monday morning, up substantially from its low of just over $57 in early May, but up only mildly from its $68 a barrel level on June 12, the day before Israel began bombing Iran. Prices are basically flat since Friday, even after Iran said it had launched a strike on an American base in Qatar.
“Multiple oil tankers crossing the Strait of Hormuz this morning, both in and outbound,” Bloomberg’s Javier Blas wrote on X Monday morning. “No[t] even a hint of disruption. Oil loading across multiple ports in the Persian Gulf appears normal. If anything, export rates over the last week are higher than earlier in June.”
As Greg Brew, an analyst at the Eurasia Group, told me, “The Hormuz risk is generally overstated. The Iranian threats are mostly rhetoric and meant for domestic political consumption. Hardliners in particular will use threats to close the strait as a means of letting off steam following the U.S. bombing of Fordow.”
“In reality,” he went on, “Iran faces a massive disparity in forces in the Gulf. A move to close Hormuz would be near suicidal as it would expand the scope of the war, drag in the Gulf states as well as the U.S., and imperil Iran’'s own energy exports at a time when the regime will need every financial and economic lifeline it can get.”
Inasmuch as oil prices have moved in the past few weeks, it’s been in response to the perceived increased risk of some kind of cataclysm to the world oil trade — even if the actual chances of the strait being entirely closed to tanker traffic remains low.
“Prices remain elevated on account of the regional risk, and are likely to remain in the $70s or low $80s until we see a pathway toward broader de-escalation,” Brew said.
For the American oil industry, however, a more nervous market might be a more profitable one.
Aniket Shah, an analyst at Jefferies, wrote a note to clients over the weekend attributing the increase since May to “rising tensions around the Strait of Hormuz, which channels ~20% of global oil shipments.”
“While the US imports less Middle Eastern oil than in past decades, global price shocks still drive up domestic fuel and transport costs,” he wrote.
In the months running up to the recent oil price increase, American drillers were facing an unpleasant combination of tariffs, increased production overseas (encouraged by Trump), and low prices at home, which wrecked their capital planning. Some domestic oil and gas drillers like Matador in April and Diamondback in May told their investors they planned to decrease their planned capital expenditures; over the past two months, drillers have been slowly but steadily taking rigs offline, according to the widely watched Baker Hughes rig count.
Conflict in the Middle East could therefore provide some relief (at least for the oil and gas industry) at home. “U.S. producers are among the winners here,” Brew told me. “A few months of higher prices will offer a nice hedge for shale drillers and ease their plans to reduce expenditure and output for the year.”
But higher profits for oil drillers will not necessarily translate into increased production, as Trump has commanded. “Since this is all based on risk premium and does not reflect a change in fundamentals, shale drillers are likely to deliver the gains to shareholders rather than pumping the money back into production,” Brew explained. “An overall drop in U.S. onshore output in 2025 is probably still in the cards.”
In that scenario, oil company profits would rise while production would fall year-over-year. And that would likely mean an even more infuriated Trump, who has also recently reignited his campaign to push Federal Reserve Chair Jerome Powell to cut interest rates, citing several months of low inflation.
“Elevated oil prices risk stalling recent disinflation trends and complicates the Fed’s path to rate cuts,” Shah wrote.
Even if the strait remains open, if oil prices don’t fall, expect more Truths.
On record-breaking temperatures, oil prices, and Tesla Robotaxis
Current conditions: Wildfires are raging on the Greek island of Chios • Forecasters are monitoring a low-pressure system in the Atlantic that could become a tropical storm sometime today • Residents in eastern North Dakota are cleaning up after tornadoes ripped through the area over the weekend, killing at least three people.
A dangerous heat wave moves from the Midwest toward the East Coast this week, and is expected to challenge long-standing heat records. In many places, temperatures could hit 100 degrees Fahrenheit and feel even warmer when humidity is factored in. “High overnight temperatures will create a lack of overnight cooling, significantly increasing the danger,” according to the National Weather Service. Extreme heat warnings and advisories are in effect from Maine through the Carolinas, across the Ohio Valley and down into southern states like Mississippi and Louisiana. “It’s basically everywhere east of the Rockies,” National Weather Service meteorologist Mark Gehring told The Associated Press. “That is unusual, to have this massive area of high dew points and heat.”
AccuWeather
Regional grid operator PJM Interconnection, which covers 13 states, issued an energy emergency alert for today. The alert urges power transmission and generation owners to delay any planned maintenance so that no grid sources are out of commission as temperatures soar. A heat wave of this nature is rare this early in the summer. The last time temperatures hit 100 degrees in June in New York City, for example, was in 1995, according to AccuWeather. Heat waves are becoming more frequent and more intense as the climate warms. Here’s a look at how these events have changed over the past 60 years or so:
Oil markets are jittery this morning after Iran’s parliament endorsed a measure to block the Strait of Hormuz in response to U.S. strikes on Iranian nuclear facilities. About 20% of the world’s oil and liquified natural gas shipments travel through the shipping route, and as The Wall Street Journalexplains, the supplies “dictate prices paid by U.S. drivers and air travelers.” Oil prices rose to five-month highs this morning on the news. Tehran has long threatened to close the strait, but such a move is seen as unlikely because it would disrupt Iran’s own energy exports, which are its “sole global energy revenue stream,” one analyst told the Journal.
A handful of climate-related provisions in the GOP’s reconciliation bill are in limbo after the Senate parliamentarian advised that the policies violated the “Byrd Rule,” i.e. were deemed extraneous to budgetary matters, and thus were subject to a 60-vote threshold instead of the simple majority allowed for reconciliation. The provisions include:
The Senate Finance Committee is set to meet with the parliamentarian today.
In case you missed it: The Supreme Court on Friday gave the green light for fuel producers to challenge a Clean Air Act waiver issued by the EPA that lets California set tougher vehicle emissions standards than those at the federal level. A lower court rejected the lawsuit from Diamond Alternative Energy and other challengers last year, but as Justice Brett Kavanaugh wrote for the majority, California’s ambitious Zero-Emission Vehicle Program is hurting fuel producers, so they have standing to sue. The vote was 7 to 2, with Justices Sonia Sotomayor and Ketanji Brown Jackson dissenting.
As Heatmap’s Katie Brigham has explained, if the EPA waiver is eliminated, Tesla could take a big financial hit. That’s because the zero-emissions vehicle program lets automakers earn credits based on the number and type of ZEVs they produce, and since Tesla is a pure-play EV company, it has always generated more credits than it needs. “The sale of all regulatory credits combined earned the company a total of $595 million in the first quarter [of 2025] on a net income of just $409 million,” Brigham reported. “That is, they represented its entire margin of profitability. On the whole, credits represented 38% of Tesla’s net income last year.”
Tesla launched its Robotaxi service in Austin, Texas, over the weekend. A small number of rides were doled out to hand-picked influencers and retail investors, and a Tesla employee sat in the front passenger seat of each autonomous Model Y to monitor safety. The rollout was “uncharacteristically low-key,” Bloombergreported, but CEO Elon Musk said the company is being “super paranoid about safety.” San Francisco, Los Angeles, and San Antonio are rumored to be the next cities slated for Robotaxi service. “Tesla is still behind Waymo, by several years,” wrote Jameson Dow at Electrek. “But Waymo has also not been scaling particularly quickly, and certainly both are slower than a lot of techno-optimists would have liked. So we’ll have to see which tortoise wins this race.” The stakes are pretty high: Investment management firm ARK Invest projected that Robotaxis could bring in $951 billion for Tesla by 2029 and make up 90% of the company’s earnings.
A new report from energy think tank Ember concludes that in the world’s sunniest cities, it’s now possible (and economically viable) to get at least 90% of the way to constant solar electricity output for every hour of the day, 365 days a year.
A conversation with Mary King, a vice president handling venture strategy at Aligned Capital
Today’s conversation is with Mary King, a vice president handling venture strategy at Aligned Capital, which has invested in developers like Summit Ridge and Brightnight. I reached out to Mary as a part of the broader range of conversations I’ve had with industry professionals since it has become clear Republicans in Congress will be taking a chainsaw to the Inflation Reduction Act. I wanted to ask her about investment philosophies in this trying time and how the landscape for putting capital into renewable energy has shifted. But Mary’s quite open with her view: these technologies aren’t going anywhere.
The following conversation has been lightly edited and abridged for clarity.
How do you approach working in this field given all the macro uncertainties?
It’s a really fair question. One, macro uncertainties aside, when you look at the levelized cost of energy report Lazard releases it is clear that there are forms of clean energy that are by far the cheapest to deploy. There are all kinds of reasons to do decarbonizing projects that aren’t clean energy generation: storage, resiliency, energy efficiency – this is massively cost saving. Like, a lot of the methane industry [exists] because there’s value in not leaking methane. There’s all sorts of stuff you can do that you don’t need policy incentives for.
That said, the policy questions are unavoidable. You can’t really ignore them and I don’t want to say they don’t matter to the industry – they do. It’s just, my belief in this being an investable asset class and incredibly important from a humanity perspective is unwavering. That’s the perspective I’ve been taking. This maybe isn’t going to be the most fun market, investing in decarbonizing things, but the sense of purpose and the belief in the underlying drivers of the industry outweigh that.
With respect to clean energy development, and the investment class working in development, how have things changed since January and the introduction of these bills that would pare back the IRA?
Both investors and companies are worried. There’s a lot more political and policy engagement. We’re seeing a lot of firms and organizations getting involved. I think companies are really trying to find ways to structure around the incentives. Companies and developers, I think everybody is trying to – for lack of a better term – future-proof themselves against the worst eventuality.
One of the things I’ve been personally thinking about is that the way developers generally make money is, you have a financier that’s going to buy a project from them, and the financier is going to have a certain investment rate of return, or IRR. So ITC [investment tax credit] or no ITC, that IRR is going to be the same. And the developer captures the difference.
My guess – and I’m not incredibly confident yet – but I think the industry just focuses on being less ITC dependent. Finding the projects that are juicier regardless of the ITC.
The other thing is that as drafts come out for what we’re expecting to see, it’s gone from bad to terrible to a little bit better. We’ll see what else happens as we see other iterations.
How are you evaluating companies and projects differently today, compared to how you were maybe before it was clear the IRA would be targeted?
Let’s say that we’re looking at a project developer and they have a series of projects. Right now we’re thinking about a few things. First, what assets are these? It’s not all ITC and PTC. A lot of it is other credits. Going through and asking, how at risk are these credits? And then, once we know how at risk those credits are we apply it at a project level.
This also raises a question of whether you’re going to be able to find as many projects. Is there going to be as much demand if you’re not able to get to an IRR? Is the industry going to pay that?
What gives you optimism in this moment?
I’ll just look at the levelized cost of energy and looking at the unsubsidized tables say these are the projects that make sense and will still get built. Utility-scale solar? Really attractive. Some of these next-gen geothermal projects, I think those are going to be cost effective.
The other thing is that the cost of battery storage is just declining so rapidly and it’s continuing to decline. We are as a country expected to compare the current price of these technologies in perpetuity to the current price of oil and gas, which is challenging and where the technologies have not changed materially. So we’re not going to see the cost decline we’re going to see in renewables.
