Are these minerals even economically viable?

President Donald Trump is going to be talking rocks with his Ukrainian counterpart Volodymyr Zelenskyy during their Friday meeting in Washington, D.C., where they will sign a “very big agreement,” Trump said Wednesday.
As the Trump administration has ramped up talks to end the war in Ukraine, shift America’s strategic priorities away from Europe, and build a new relationship with Russia, it has also become intensely interested in Ukraine’s supposed mineral wealth, with Ukrainian and American negotiators working on a deal to create an investment fund for the country’s reconstruction that would be partially funded by developing the country’s mineral resources.
But exactly what minerals are in Ukraine and if they’re economically viable to extract is a matter of contention.
So-called critical minerals and rare earths have a way of finding themselves in geopolitical hotspots. This is because they’re not particularly rare, but the immense capital required to cost effectively find them, mine them, and process them is.
“A lot of countries have natural resources. We don’t mine everything that exists underground. We look for projects that are economically competitive,” Gracelin Baskaran, director of the critical minerals security program at the Center for Strategic and International Studies, told me.
Baskaran pointed out, it was precisely Russia’s full-scale invasion of Ukraine that kicked the United States’ interest in building up supplies of critical minerals and rare earths outside of China — which dominates the industry — into overdrive.
“It was a fortuitous moment in that way for Ukraine’s resources, because they weren’t necessarily being mined before,” she said.
And Ukraine has done its best to promote and take advantage of its mineral resources, even if there’s some ambiguity about what exactly they are, and if they can be profitably extracted at scale.
While often conflated, critical minerals and rare earths are distinct. The so-called “rare earths” are 17 similar elements, which the U.S. Geological Survey explicitly says are “relatively abundant,” like scandium and yttrium. Critical minerals are a more amorphous group, with the USGS listing out 50 (including the rare earths) as well as commonly known minerals like titanium, nickel, lithium, tin, and graphite, with uses in batteries, alloys, semiconductors, and other high value energy, defense, and technology applications.
When countries are desperate for outside assistance or their patrons are desperate to see some return on their “investments” in military and foreign aid, as Bloomberg’s Javier Blas has pointed out, the minerals tend to show up — just look at the “$1 trillion in untapped mineral deposits” the United States identified in Afghanistan in 2010. Ten years later when the USGS looked at Afghanistan’s mineral industries, the rare earths remained untapped and instead the country was largely exporting talc and crushed marble to its neighbors.
Ukrainians have been eager to show there are economically viable and valuable minerals in the country, including a claim by one Ukrainian official in early 2022 that “about 5% of all the world’s ‘critical raw materials’ are located in Ukraine,” while a pair of Ukrainian researchers claimed there was 500,000 tons of unmined lithium oxide resources. More recently the country has claimed to have rare earths, and that President Trump has taken a special interest in.
Many industry experts doubt there’s any significant reserves of rare earths in the country, with the exception of scandium, which is used in aluminum alloys and fuel cells. Ukraine does have a significant mining industry and has produced substantial amounts of iron ore and manganese, along with reserves of graphite, titanium, cobalt, and uranium, many of which are those so-called “critical minerals” with uses for energy and defense.
“There do not appear to be hardly any economically viable rare earths in the country – that was largely a misuse of a term someone heard,” Morgan Bazillian, director of the Payne Institute and a public policy professor at the Colorado School of Mines, told me in an email.
Blas has documented a game of telephone whereby rare earths and critical minerals are conflated to make it seem like the former exists in abundance underneath Ukraine. Despite the doubts, President Trump said on Wednesday during his cabinet meeting “we’ll be really partnering with Ukraine, [in] terms of rare earth. We very much need rare earth. They have great rare earth.”
While there’s disagreement about exactly what Ukraine has to offer in terms of minerals, the interest in building up supplies of minerals is part and parcel of what is now a bipartisan priority to build up supplies and the ability to process and refine minerals used for a variety of defense, industrial, and energy applications.
To the extent the United States is able to jumpstart any new mineral operations in postwar Ukraine, it would require first repairing the country’s greatly damaged infrastructure, which has been wrecked by the very conflict that has spiked interest in the country’s mineral sector.
“Their infrastructure is decimated. Rebuilding it will be the priority, getting industry moving again will take time – including from basic services like electricity,” Bazillian told me.
And after that, much basic work needs to be done before any mining can happen, like an updated geological survey of the country, which hasn’t been done since the country was part of the Soviet Union. And all that’s before starting the process for opening a mine, something that on average takes 18 years to do.
“You need to have a geological mapping. You need to identify investors who want to go in. You need to build infrastructure,” Baskaran said.
“Ukraine has undeveloped or untapped potential that could be utilized. And the question is whether that untapped potential is economically viable, and we don’t know yet.”

Current conditions: The Pacific Northwest’s second atmospheric river in a row is set to pour up to 8 inches of rain on Washington and Oregon • A snow storm is dumping up to 6 inches of snow from North Dakota to northern New York • Warm air is blowing northeastward into Central Asia, raising temperatures to nearly 80 degrees Fahrenheit at elevations nearly 2,000 feet above sea level.
Heatmap’s Jael Holzman had a big scoop last night: The three leading Senate Democrats on energy and permitting reform issues are a nay on passing the SPEED Act. In a joint statement shared exclusively with Jael, Senate Energy and Natural Resources ranking member Martin Heinrich, Environment and Public Works ranking member Sheldon Whitehouse, and Hawaii senator Brian Schatz pledged to vote against the bill to overhaul the National Environmental Policy Act unless the legislation is updated to include measures to boost renewable energy and transmission development. “We are committed to streamlining the permitting process — but only if it ensures we can build out transmission and cheap, clean energy. While the SPEED Act does not meet that standard, we will continue working to pass comprehensive permitting reform that takes real steps to bring down electricity costs,” the statement read. To get up to speed on the legislation, read this breakdown from Heatmap’s Emily Pontecorvo.

In June, Heatmap’s Matthew Zeitlin explained how New York State was attempting to overcome the biggest challenge to building a new nuclear plant — its deregulated electricity market — by tasking its state-owned utility with overseeing the project. It’s already begun staffing up for the nuclear project, as I reported in this newsletter. But it’s worth remembering that the New York Power Authority, the second-largest government-controlled utility in the U.S. after the federal Tennessee Valley Authority, gained a new mandate to invest in power plants directly again when the 2023 state budget passed with measures calling for public ownership of renewables. On Tuesday, NYPA’s board of trustees unanimously approved a list of projects in which the utility will take 51% ownership stakes in a bid to hasten construction of large-scale solar, wind, and battery facilities. The combined maximum output of all the projects comes to 5.5 gigawatts, nearly double the original target of 3 gigawatts set in January.
But that’s still about 25% below the 7 gigawatts NYPA outlined in its draft proposal in July. What changed? At a hearing Tuesday morning, NYPA officials described headwinds blowing from three directions: Trump’s phaseout of renewable tax credits, a new transmission study that identified which projects would cost too much to patch onto the grid, and a lack of power purchase agreements from offtakers. One or more of those variables ultimately led private developers to pull out at least 16 projects that NYPA would have co-owned.

During World War II, the Lionel toy train company started making components for warships, the Ford Motor Company produced bomber planes, and the Mattatuck Manufacturing Company known for its upholstery nails switched to churning out cartridge clips for Springfield rifles. In a sign of how severe the shortfall of equipment to generate gas-powered electricity has become, would-be supersonic jet startups are making turbines. While pushing to legalize flights of the supersonic jets his company wants to build, Blake Scholl, the chief executive of Boom Supersonic, said he “kept hearing about how AI companies couldn’t get enough electricity,” and how companies such as ChatGPT-maker OpenAI “were building their own power plants with large arrays of converted jet engines.” In a thread on X, he said that, “under real world conditions, four of our Superpower turbines could do the job of seven legacy units. Without the cooling water required by legacy turbines!”
The gas turbine crisis, as Matthew wrote in September, may be moving into a new phase as industrial giants race to meet the surging demand. In general, investors have rewarded the effort. “But,” as Matthew posed, “what happens when the pressure to build doesn’t come from customers but from competitors?” We may soon find out.
It is, quite literally, the stuff of science fiction, the kind of space-based solar power plant that Isaac Asimov imagined back in 1940. But as Heatmap’s Katie Brigham reported in an exclusive this morning, the space solar company Overview Energy has emerged from stealth, announcing its intention to make satellites that will transmit energy via lasers directly onto Earth’s power grids. The company has raised $20 million in a seed round led by Lowercarbon Capital, Prime Movers Lab, and Engine Ventures, and is now working toward raising a Series A. The way the technology would work is by beaming the solar power to existing utility-scale solar projects. As Katie explained: “The core thesis behind Overview is to allow solar farms to generate power when the sun isn’t shining, turning solar into a firm, 24/7 renewable resource. What’s more, the satellites could direct their energy anywhere in the world, depending on demand. California solar farms, for example, could receive energy in the early morning hours. Then, as the sun rises over the West Coast and sets in Europe, ‘we switch the beam over to Western Europe, Morocco, things in that area, power them through the evening peak,’” Marc Berte, the founder and CEO of Overview Energy, told her. He added: “It hits 10 p.m., 11 p.m., most people are starting to go to bed if it’s a weekday. Demand is going down. But it’s now 3 p.m. in California, so you switch the beam back.”
In bigger fundraising news with more immediate implications for our energy system, next-generation geothermal darling Fervo Energy has raised another $462 million in a Series E round to help push its first power plants over the finish line, as Matthew wrote about this morning.
When Sanae Takaichi became the first Japanese woman to serve as prime minister in October, I told you at the time how she wanted to put surging energy needs ahead of lingering fears from Fukushima by turning the country’s nuclear plants back on and building more reactors. Her focus isn’t just on fission. Japan is “repositioning fusion energy from a distant research objective to an industrial priority,” according to The Fusion Report. And Helical Fusion has emerged as its national champion. The Tokyo-based company has signed the first power purchase agreement in Japan for fusion, a deal with the regional supermarket chain Aoki Super Co. to power some of its 50 stores. The Takaichi administration has signaled plans to increase funding for fusion as the new government looks to hasten its development. While “Japan still trails the U.S. and China in total fusion investment,” the trade newsletter reported, “the policy architecture now exists to close that gap rapidly.”
Another day, another emerging energy or climate technology gets Google’s backing. This morning, the carbon removal startup Ebb inked a deal with Google to suck 3,500 tons of CO2 out of the atmosphere. Ebb’s technology converts carbon dioxide from the air into “safe, durable” bicarbonate in seawater and converting “what has historically been a waste stream into a climate solution,” Ben Tarbell, chief executive of Ebb, said in a statement. “The natural systems in the ocean represent the most powerful and rapidly scalable path to meaningful carbon removal … Our ability to remove CO2 at scale becomes the natural outcome of smart business decisions — a powerful financial incentive that will drive expansion of our technology.”
The Series E round will fund the enhanced geothermal company’s flagship Cape Station project.
The enhanced geothermal company Fervo is raising another $462 million, bringing on new investors in its Series E equity round.
The lead investor is a new one to the company’s books: venture capital firm B Capital, started by Facebook co-founder Eduardo Saverin. Fervo did not disclose a valuation, but Axios reported in March that it had been discussing an IPO in the next year or two at a $2 billion to $4 billion valuation.
Much of the capital will be devoted to further investments in its Cape Station facility in Utah, which is due to start generating 100 megawatts of grid power by the end of 2026. A smaller project in Nevada came online in 2023.
Fervo’s last equity round was early last year, when it raised $255 million led by oil and gas company Devon. It also raised another $206 million this past summer in debt and equity to finance the Cape Station project, specifically, and reported faster, deeper drilling numbers.
“I think putting pedal to the metal is a good way to put it. We are continuing to make progress at Cape station, which is our flagship project in Southwest Utah, and some of the funding will also be used for early stage development at other projects and locations to expand Fervo’s reach across the Western U.S.,” Sarah Jewett, Fervo’s senior vice president of strategy, told me
“Enhanced geothermal” refers to injecting fluid into hot, underground rocks using techniques borrowed from hydraulic fracturing for oil and gas. Along with the geothermal industry as a whole, Fervo has found itself in the sweet spot of energy politics. It can provide power for technology companies with sustainability mandates and states with decarbonization goals because it produces carbon-free electricity. And it can host Republican politicians at its facilities because the power is 24/7 and employs labor and equipment familiar to the oil and gas industry. While the Trump administration has been on a warpath against solar and (especially) wind, geothermal got a shoutout in the White House’s AI Action Report as an electricity source that should be nurtured.
“Being clean and operating around the clock is just a really strong value proposition to the market,” Jewett said. “Utilizing an oil and gas workforce is obviously a big part of that story; developing in rural America to serve grids across the West; producing clean, emissions-free energy. It's just a really nice, well-rounded value proposition that has managed to maintain really strong support across the aisle in Washington despite the administration shift.”
But bipartisan support on its own can’t lead to gigawatts of new, enhanced geothermal powering the American west. For that Fervo, like any venture-backed or startup energy developer, needs project finance, money raised for an individual energy project (like a solar farm or a power plant) that must be matched by predictable, steady cashflows. “That is, obviously the ultimate goal, is to bring the cost of capital down for these projects to what we call the ‘solar standard,’’’ Jewett said, referring to a minimum return to investors of below 10%, which solar projects can finance themselves at.
While solar power at this point is a mature technology using mass-manufactured, standardized parts having very good foreknowledge of where it will be most effective for generating electricity (it’s where the sun shines), enhanced geothermal is riskier, both in finding places to drill and in terms of drilling costs. Project finance investors tend to like what they can easily predict.
“We are well on our way to do it,” Jewett said of bringing down the perceived risk of enhanced geothermal. “This corporate equity helps us build the track record that we need to attract” project finance investors.
Whether enhanced geothermal is price competitive isn’t quite clear: Its levelized cost of energy is estimated to be around twice utility scale solar's, although that metric doesn’t give it credit for geothermal’s greater reliability and lack of dependence on the weather.
While Cape Station itself is currently covered in snow, Jewett said, construction is heating up. The facility has three power plants installed, a substation and transmission and distribution lines starting to be put up, putting the facility in line to start generating power next year, Jewett said.By the time it starts generating power for customers, Fervo hopes to have reduced costs even more.
“Cost reductions happen through learning by doing — doing it over and over and over again. We have now drilled over 30 wells at the Cape Station field and we’re learning over time what works best,” Jewett said.
Overview Energy has raised $20 million already and is targeting a Series A early next year.
When renowned sci-fi author Isaac Asimov first wrote about space-based solar power in the 1940s, it helped inspire engineers and the federal government alike to take the idea seriously. By the 1970s, a design had been patented and feasibility studies were underway. But those initial efforts didn’t get far — challenges with launch costs, constructing the necessary structures in space, and energy conversion efficiency proved too much for scientists to overcome.
Now the idea is edging ever closer to reality.
The space solar company Overview Energy emerged from stealth today, announcing its intention to make satellites that will transmit energy via lasers directly onto the Earth’s grid, targeting preexisting utility-scale solar installations. The startup has already raised $20 million in a seed round led by Lowercarbon Capital, Prime Movers Lab, and Engine Ventures, and is now working on raising a Series A.
The core thesis behind Overview is to allow solar farms to generate power when the sun isn’t shining, turning solar into a firm, 24/7 renewable resource. What’s more, the satellites could direct their energy anywhere in the world, depending on demand. California solar farms, for example, could receive energy in the early morning hours. Then, as the sun rises over the West Coast and sets in Europe, “we switch the beam over to Western Europe, Morocco, things in that area, power them through the evening peak,” Marc Berte, the founder and CEO of Overview Energy, explained. “It hits 10 p.m., 11 p.m., most people are starting to go to bed if it’s a weekday. Demand is going down. But it’s now 3 p.m. in California, so you switch the beam back.”
That so-called “geographic untethering” will be a key factor in making all of this economically feasible one day, Berte told me. The startup is targeting between $60 and $100 per megawatt-hour by 2035, when it aims to be putting gigawatts of commercial space solar on the grid. “It’s 5 o’clock somewhere,” Berte told me. “You’re profitable at $100 bucks a megawatt-hour somewhere, instantaneously, all the time.”
Making the math pencil out has also meant developing super-efficient lasers and eliminating all power electronics on its custom spacecraft. The type of light Overview beams to earth — called “near-infrared” and invisible to the naked eye — is also very efficiently converted into electricity on a solar cell. While pure sunlight is only converted at 20% efficient, near-infrared light is converted at 50% efficiency. Thus, Overview enables solar panels to operate even more efficiently during the night than during the day.
Today, the startup also announced the successful demonstration of its ability to transmit energy from a moving aircraft to a ground receiver three miles below — the first time anyone has beamed high power from a moving source. Although Overview’s satellites will eventually need to transmit light from much farther away — around 22,000 miles from Earth — the test proved that the fundamental technical components work together as planned.
“There’s no functional difference from what we just did from an airplane to what we’re going to do in 10 years at gigawatts from space,” Berte told me. “The same beacon, the same tracking, the same mirror, the same lasers, all the same stuff, just an airplane instead of space.”
Overview’s ultimate goal is ambitious to say the least: It’s aiming to design a system that can deliver the equivalent of 10% to 20% of all global electricity use by 2050. To get there, it’s aiming to put megawatts of power on the grid by 2030 and gigawatts by the mid-2030s. Its target customers include independent power producers, utilities, and data centers, and the company currently has a SpaceX launch booked for early 2028. At this point, Berte says Overview will likely be starting up its own prototype production line, which it will scale in the years to follow.
That certainly won’t be a simple undertaking. To produce a gigawatt of power, Overview will need to deploy 1,000 huge satellites, each measuring around 500 to 600 feet across and weighing about 8 to 10 tons. The largest satellites currently in space are about 100 to 150 feet across, and roughly 5 to 10 tons. “No one really mass-manufactures satellites in the kind of quantities required,” Berte explained, and nobody is producing the design and form factor that Overview requires. “So we are going to have to in-source a lot of the integration for that.”
But while the startup’s satellites will span the length of about two football fields, they fold up neatly into a package about the size of a shipping container, making it possible for them to fit on a SpaceX rocket, for example. When the satellites beam their power down to Earth, they’ll target a beacon — also shipping container-sized — that will be placed in the middle of the solar farm.
Initially, Berte told me, Overview will target deployment in places where logistical challenges make energy particularly expensive — think Alaska or island states and territories such as Guam, Hawaii, and Puerto Rico. But first, the company must demonstrate that its tech works from thousands of miles away. That’s what the funding from its forthcoming Series A, which Berte expects to close in spring of next year, is intended for.
“That is to take us to the next step, which is now do it in space. And after that, it’s now do it in space, but big,” he told me. “So it’s crawl, walk, run, but most importantly, the technology and how you do it doesn’t change.”
