Energy costs remain high — and early voting has begun.
Fossil fuels are the real October surprise.
Even the smallest wave, tidal, and river-current projects are currently licensed as if they were 1,000-megawatt dams.
Tucked inside the Senate’s ambitious new permitting bill, the Bipartisan American Affordability and Jobs Act, is a major win for an energy technology that often flies under the radar: marine power. Small-scale wave, tidal, and river-current projects could help power everything from remote communities and military installations to ocean sensors and coastal desalination systems — at least in theory.
Drawing largely from the bipartisan FLOWS Act, introduced in the Senate last December but never brought to a floor vote, BAAJA aims to streamline the licensing pathway for so-called micro hydrokinetic projects, which harness moving water without dams or reservoirs and have a capacity of 5 megawatts or less. The bill would give the Federal Energy Regulatory Commission one year to act on commercial license applications for these projects, while exempting them from full review under the National Environmental Policy Act. It would also allow FERC to issue 10- to 20-year licenses, giving projects a pathway to long-term commercial operation, as opposed to relying on pilot licenses designed for temporary testing.
The bill wouldn’t eliminate environmental oversight altogether. Small-scale marine energy projects would still undergo basic environmental screenings as a part of FERC licensing, and would still require state and local permits, which can trigger their own environmental reviews. They’d also remain subject to the Endangered Species Act and the Clean Water Act — though the bill would expedite reviews under both of those laws, too. On the whole, the reforms are intended to give developers and investors alike a quicker, more predictable timeline.
“Taking a 1-megawatt marine energy project and trying to license it like it’s a 1,000-megawatt conventional dam just wasn’t working. It was apples to oranges,” Matthew Allen, senior director of legislative affairs at the National Hydropower Association, told me. “Recognizing that it deserves its own process could be a tremendous market signal for the technology.”
After all, this tech certainly doesn’t look like large-scale hydropower, where colossal dams unleash thousands of tons of water per second that rush through electricity-generating turbines to the river below. Such gargantuan infrastructure projects typically require favorable geography — think big rivers running through steep, mountainous terrain, where a dam can create a sharp drop in elevation. And with most of the best sites in the U.S. already developed, the country is unlikely to build many new greenfield hydro projects anytime soon.
But less-developed marine energy technologies have barely scratched the surface of their potential. Some look like large buoys, bobbing with the ocean swells and converting that motion into electricity. Others use turbines anchored to the seafloor or riverbed, spinning as tides ebb and flow or river currents rush past. While these devices generate essentially zero power for the grid today, in theory the resource is enormous: The National Renewable Energy Laboratory estimates that wave, tidal, and river-current projects have the technical potential to generate a staggering 2,300 terawatt-hours of electricity annually — more than half of the country’s total electricity generation last year. Wave energy alone accounts for about 60% of that number.
Of course, technical potential is a long way from practical reality. Economic constraints, environmental regulations, competing water uses, and public acceptance could limit uptake of these technologies. NREL suggests that we would be lucky to eventually tap even 10% of marine energy’s potential. Meanwhile, most of the tech remains in the pilot or demonstration stage in the U.S. — which is exactly why expediting permitting for small-scale projects stands to have significant impact.
“Marine energy is so new and still so novel that a 5-megawatt device, it doesn’t even exist right now,” Jennifer Garson, former director of the Water Power Technologies Office during the Biden administration, told me. “So you’re still talking about a good amount of headroom for being able to deploy smaller-scale marine energy devices in rivers and nearshore.”
Early deployments have largely served remote or island communities. In the 70-person Alaska Native village of Igiugig, for example, Ocean Renewable Power Company installed two 35-kilowatt turbine systems on a local riverbed, designed to supply nearly half the village’s power and thus reduce reliance on expensive diesel generators. While the project’s pilot license expires in three years, the permitting bill could offer a pathway to continued power generation.
The lack of a commercial licensing pathway has already led to the demise of one promising project, National Hydropower Association senior program manager Kelly Rogers told me. Verdant Power’s tidal energy pilot in New York City’s East River — the first project of its type to receive a license in the U.S. — officially shuttered in 2021 when said pilot license expired. By then, its turbines had delivered over 312 megawatt-hours of total electricity to the grid, harnessing the tides as they flowed in and out of the saltwater channel.
Other companies in this space include wave energy startups Oscilla Power and CalWave, which make surface-floating and submerged wave energy converters, respectively, with the goal of selling to utility customers and remote communities alike. C-Power, another early-stage wave energy company, is focused on powering off-grid equipment like ocean sensors. And while all have received at least some venture backing, a significant portion of their funding comes from Department of Energy grants.
In 2022, all three received DOE funding to trial their tech at PacWave, an Oregon-based facility that’s the first grid-connected wave energy test site in the continental U.S. Backed by the DOE, the facility secured all its necessary state and federal approvals in advance so that companies working there could largely bypass the permitting process and get their tech straight into the water. But getting there, Garson told me, involved an arduous 15 years of negotiations among the DOE, the Bureau of Ocean Energy Management, and state and local authorities before the facility could open for testing this August.
The permitting bill can only do so much to accelerate a permitting process like this, Garson explained. Even with a faster FERC licensing process, all projects in federal waters — generally those more than 3 nautical miles from shore — will still need a separate lease from BOEM, a complex process that the bill’s new permitting pathway wouldn’t replace. “One of the complexities of anything that you do with water is you just have so many split jurisdictional challenges and questions,” she told me.
It’s also telling that as of yet, there are no wave energy devices in PacWave’s waters, as the Trump administration’s federal funding freeze has scrambled the plans of some of the marine energy developers who’d originally intended to test there. Oregon startup AquaHarmonics, for example, was on track to deploy its wave energy converter at PacWave but had to shut down last year after the Trump administration withheld its previously allocated grant money.
“A lot of the device deployments, particularly in the United States, have been contingent on or reliant on federal funding,” Garson told me. “You’re dealing with still such early-stage R&D that it really points to a necessity for the federal government to be in this space”
But while the federal budget for emerging marine energy technologies has generally grown year over year, Garson said relatively little of that money is actually reaching developers. When she was still at the DOE, for example, the Water Power Technologies Office launched a funding solicitation offering up to $112.5 million in total for wave energy companies to test their devices at sea, including at PacWave. But while the DOE was supposed to announce the winners last year, Garson said it has yet to do so — and it’s disbursed no funding, either.
“That’s a long time for a lot of these companies to sit and wait for any funding to even be available,” she told me. CalWave, at least, still plans to hook its system up at PacWave, as the startup’s CEO, Marcus Lehmann, told me the company is “now in the construction phase of installing the first grid-connected system” and that it plans to launch at PacWave sometime in 2027 or 2028.
He sees the permitting bill as “really critical” in helping early-stage projects “get online faster, and just to prove it out on a community level or a microgrid level” before scaling up to larger installations and device arrays that would likely exceed the 5-megawatt threshold.
“Regulatory certainty, particularly when you’re dealing with capital-tight startups — great. Anything that makes their lives easier, I am all for,” Garson told me, calling the existing permitting structure for marine energy “byzantine.” But she doesn’t think that if the bill passes we’ll suddenly see a slew of wave, tidal, and river-current projects coming online. “You’re still talking about relatively small outputs of power until we reach more [technological] maturity.”
But it could certainly be a first step toward recognizing the potential of water power technologies beyond conventional hydropower — and giving them a place in the broader clean energy conversation. “This is a meaningful amount of power to a lot of people. We just tend to get so lost in the gigawatt conversation,” Garson told me.
And while developers do measure these projects in kilowatts and megawatts for now, one day they too could help move the needle at the gigawatt level. As Garson put it, “If we can figure out how to unlock the ocean — power for everybody, everywhere.”
On Korea’s Westinghouse wishes, a lithium deal, and British heat pumps
Current conditions: New York City’s temperature is set to rise as high as 80 degrees Fahrenheit this week before plunging as the coldest weather so far this season blows into the Northeast • Temperatures in Denver have been above 80 degrees for the past 11 days straight • Nearly 200,000 households, mostly in Florida, are still without electricity after Hurricane Isaias.
In theory, news of President Donald Trump’s deal with Russia to pump millions of tons of diesel into the global market should have eased oil prices. Instead, all three major crude benchmarks spiked Monday by nearly 1.5%. Only West Texas Intermediate, the U.S. metric that has largely evaded the worst knock-on effects of conflict in the Middle East, remained below $100 per barrel. The hike came as the Houthi attacks on Saudi Arabia over the weekend weighed heavily on investors’ minds, eclipsing whatever impact the diesel deal could have had.
Speaking at an industry summit in Riyadh, from which executives from Western oil majors bowed out at the last minute following missile strikes on the airport in the Saudi capital, the head of the country’s state oil company warned that not even Saudi Arabia had the capacity to protect all the supply routes off its coasts for getting hydrocarbons from the region to the world. “No nation, even one as capable and confident as ours, can safeguard them alone,” Aramco CEO Amin Nasser said, according to Arab News.
TotalEnergies took more than $1 billion from the Trump administration to kill off its offshore wind projects. But don’t take that as a sign the French energy behemoth is abandoning American renewables. The company’s joint venture with private equity giant KKR announced a deal to add 700 megawatts of solar to its portfolio of 1.4 gigawatts. The $1.2 billion acquisition includes three utility-scale solar farms in Texas and Ohio that are expected to reach commercial operation in the first quarter of next year.

South Korea is in a bind. The Korea Electric Power Corporation, through its subsidiary Korea Hydro & Nuclear Power, represents the most competent financier and builder of nuclear reactors anywhere in the democratic world, having constructed the United Arab Emirates’ debut atomic power stations relatively on time and on budget compared to U.S., French, and British projects. But the leading Korean reactor, the APR1400, allegedly borrowed from the American nuclear champion Westinghouse’s pressurized water reactor design. A yearslong legal feud ended last year with a settlement that bars the Koreans from bidding on projects in Europe or North America. In a deal this month with the Trump administration to stave off tariffs, Seoul has agreed to help finance and construct six Westinghouse AP1000s and two of its own APR1400s in the U.S., giving the Americans a leg up on nuclear construction and the Koreans a foothold in North America.
In South Korea, where the Westinghouse settlement has widely been considered unfair, the government is signaling other plans to gain more leverage. For starters, KEPCO’s chief executive Kim Dong-cheol said the claim that the settlement requires the company to pay Westinghouse $2 billion per nuclear plant to use its technology was misunderstood. “It is true that $2 billion is the ceiling, but it does not mean we will pay all of it,” he said. But the more eyebrow-raising detail in his interview with the financial newspaper Business Korea is that KEPCO is considering a plan to acquire an equity stake of between 5% and 10% in Westinghouse. Rumors of a potential deal to buy part of Westinghouse have been circulating in the Korean press for weeks now. Anything seems to be on the table these days, but when I have asked multiple sources on the U.S. side about it, all of them shrugged off the possibility to me.

When The New York Times ran a glowing profile of the lithium startup EnergyX back in 2021, industry sources at the time mocked the coverage to me as too credulous — a sign of how unsophisticated the popular American press was at writing about critical minerals at the time. The Wall Street Journal glazed the firm’s chief executive, Teague Egan, in its own profile three years later. So it was with light surprise and amusement that I read Reuters reporter Ernest Scheyder’s latest story about the company: EnergyX just signed a $2 billion binding offtake to supply the commodities giant Trafigura with the battery metal from Chile and the U.S. It’s one of the largest deals ever tied to direct lithium extraction, the technology EnergyX is trying to commercialize, which uses less water than standard methods of mining the metal. The 10-year contract comes amid growing demand from the stationary battery storage market as the grid and data centers eat what unsteady sales of electric vehicles has left on the plate.
The British government plans to cut hundreds of millions of dollars from the national program to upgrade boilers in England and Wales, providing £9,000, or nearly $12,000, to finance the switch to heat pumps. The cuts, which the Financial Times reported Monday had drawn a backlash against the ruling Labour Party, are part of a broader bid by Prime Minister Andy Burnham to slash £2 billion in the budget to make way for more military spending. The reductions began in June under former Prime Minister Keir Starmer with a study to identify potential cuts. Starmer singled out the Department of Energy Security and Net Zero, particularly after the agency received a 16% annual increase to fund projects such as the nuclear buildout at Sizewell C, carbon capture infrastructure, and insulation to make homes more energy efficient.
The move is sure to ripple across the climate policy world. Roughly a week ago, Daniel Aldana Cohen, an assistant professor at the University of California at Berkeley, was extolling the benefits of ramping up U.S. production of heat pumps in response to soaring heating prices this winter due to the fossil fuel supply crunch. “Every year that we don’t do a wartime mobilization on heat pumps, we’re ruining people’s lives,” the early advocate of a Green New Deal wrote in a post on X. “Heat pumps will always outperform heating oil, cut costs, add summer AC. And would be fantastic for labor, small businesses, worker co-ops.”
As quickly as a spark of atmospheric electricity strikes, the Ford F-150 Lightning disappeared, with the final model of the all-electric pickup truck rolling off the assembly line last year. Now, Bloomberg reports, “it has become one of the most coveted cars in America and a glowing ember in the red-hot market for used electric vehicles.” The price of a used Lightning is 50% to 60% of the sticker price, which one expert told the newswire “is really a sweet spot.”
