An anonymous reader quotes a report from The Register: Renewable energy sources could power datacenters at a lower cost than relying on nuclear generation from small modular reactors (SMRs), claims a recently revealed study. ... [A]nalysis from the Centre for Net Zero (CNZ) says it would cost 43 percent less to power a 120 MW data facility with renewables and a small amount of gas-generated energy, when compared with an SMR. It claims that a microgrid comprising offshore wind, solar, battery storage, and backed up by gas generation, would be significantly cheaper to run annually than procuring power sourced from a nuclear SMR.

[...] CNZ describes itself as an open research institute, founded by Octopus Energy Group in the UK, and claims to advise the State of California and Europe's International Energy Agency as well as the British government. While CNZ's study applies to the UK sector, where energy costs are among the highest in the industrialized world, it is likely that the overall conclusion would still be valid in other countries as well. Its analysis shows that renewables can meet 80 percent of the constant demand from a large datacenter over the course of a year. Offshore wind can provide the majority of load requirements, with gas generation backed by battery storage as a stopgap source of power representing the most cost-optimal mix.

Greater capacity in the on-site battery storage system would reduce the reliance on gas power, and this would likely happen over time as the cost of such systems is expected to come down, the report claims. But perhaps the real kicker is that CNZ estimates that microgrids powered largely by renewables could be built in approximately five years, while operational SMRs are not expected to be widely available until sometime in the next decade. CNZ says that it calculated the typical yearly resource cost (capex and opex) of powering a datacenter with a nuclear SMR, and modeled this using Python for Power System Analysis (PyPSA), an open source energy modeling tool, against two renewable energy scenarios. One was the wind, solar, battery, and gas mix, while the other omitted solar.

Liquefied CO2 will be transported by ship to "the world's first carbon shipping port," reports the Washington Post — an island in the North Sea where it will be "buried in a layer of spongy rock a mile and a half beneath the seabed."

Norway's government is covering 80% of the $1 billion first phase, with another $714 million from three fossil fuel companies toward an ongoing expansion (with an additional $150 million E.U. subsidy). As Europe's top oil and gas producer, Norway is using its fossil fuel income to see if they can make "carbon dumping" work. The world's first carbon shipment arrived this summer, carrying 7,500 metric tons of liquefied CO2 from a Norwegian cement factory that otherwise would have gone into the atmosphere... If all goes as planned, the project's backers — Shell, Equinor and TotalEnergies, along with Norway — say their facility could pump 5 million metric tons of carbon dioxide underground each year, or about a tenth of Norway's annual emissions...

[At the Heidelberg Materials cement factory in Brevik, Norway], when hot CO2-laden air comes rushing out of the cement kilns, the plant uses seawater from the neighboring fjord to cool it down. The cool air goes into a chamber where it gets sprayed with amine, a chemical that latches onto CO2 at low temperatures. The amine mist settles to the bottom, dragging carbon dioxide down with it. The rest of the air floats out of the smokestack with about 85 percent less CO2 in it, according to project manager Anders Pettersen. Later, Heidelberg Materials uses waste heat from the kilns to break the chemical bonds, so that the amine releases the carbon dioxide. The pure CO2 then goes into a compressor that resembles a giant steel heart, where it gets denser and colder until it finally becomes liquid. That liquid CO2 remains in storage tanks until a ship comes to carry it away. At best, operators expect this system to capture half the plant's CO2 emissions: 400,000 metric tons per year, or the equivalent of about 93,000 cars on the road...

[T]hree other companies are lined up to follow: Ørsted, which will send CO2 from two bioenergy plants in Denmark; Yara, which will send carbon from a Dutch fertilizer factory; and Stockholm Exergi, which will capture carbon from a Swedish bioenergy plant that burns wood waste. All of these projects have gotten significant subsidies from national governments and the European Union — essentially de-risking the experiment for the companies. Experts say the costs and headaches of installing and running carbon-capture equipment may start to make more financial sense as European carbon rules get stricter and the cost of emitting a ton of carbon dioxide goes up. Still, they say, it's hard to imagine many companies deciding to invest in carbon capture without serious subsidies...

The first shipments are being transported by Northern Pioneer, the world's biggest carbon dioxide tanker ship, built specifically for this project. The 430-foot ship can hold 7,500 metric tons of CO2 in tanks below deck. Those tanks keep it in a liquid state by cooling it to minus-15 degrees Fahrenheit and squeezing it with the same pressure the outside of a submarine would feel 500 feet below the waves. While that may sound extreme, consider that the liquid natural gas the ship uses for fuel has to be stored at minus-260 degrees. "CO2 isn't difficult to make it into a liquid," said Sally Benson, professor of energy science and engineering at Stanford University. Northern Pioneer is designed to emit about a third less carbon dioxide than a regular ship — key for a project that aims to eliminate carbon emissions. The ship burns natural gas, which emits less CO2 than marine diesel produces (though gas extraction is associated with methane leaks). The vessel uses a rotor sail to capture wind power. And it blows a constant stream of air bubbles to reduce friction as the hull cuts through the water, allowing it to burn less fuel. For every 100 tons of CO2 that Northern Lights pumps underground, it expects to emit three tons of CO2 into the atmosphere, mainly by burning fuel for shipping.
Eventually the carbon flows into a pipeline "that plunges through the North Sea and into the rocky layers below it — an engineering feat that's a bit like drilling for oil in reverse..." according to the article.

"Over the centuries, it should chemically react with the rock, eventually being locked away in minerals."

An anonymous reader quotes a report from Bloomberg: CoreWeave is expanding a data center that is projected to double the electricity needs of a city near Dallas, another example of the strains that artificial intelligence workloads are placing on the US power supply. Local officials have grappled with how to handle the increased stress on the electricity grid from the project, according to a late 2024 presentation and emails seen by Bloomberg. The site is being developed by Core Scientific and will be used by OpenAI in Denton, Texas. Last week, CoreWeave announced it would acquire Core Scientific for about $9 billion, in part, to gain direct control of its data centers aimed at supplying AI work.

Denton, about 50 miles northwest of Dallas, has almost doubled its population in the last 25 years to about 166,000 residents. To meet the spike in AI-related power demand, the city is passing on any extra costs to the data center operator and constructing additional grid infrastructure, Antonio Puente, general manager of local utility Denton Municipal Electric, said in an interview. "To serve the entire load from Core Scientific, we do have some transmission challenges," Puente said. "We will have to make some additional transmission investments." [...] Like some other large AI data center projects, the site in Denton was focused on cryptocurrency mining before pivoting to AI workloads in December. This transition means unrelenting power consumption -- the site will no longer curtail operations when power prices are high -- which will increase grid strain. "Now you're talking about a facility that has to have energy 24 hours a day, 365 days a year," Puente said. That challenge will be mitigated by the addition of backup generators and batteries, he added.

Unlike many large projects, the Denton data center didn't receive local tax exemptions. Officials expect more than $600 million in property and sales tax from the data center expansion, more than double the costs it plans to incur, according to an analysis document seen by Bloomberg. It also anticipates that 135 new jobs will be created, according to the document. The Denton site, which is already being rented by CoreWeave, is Core Scientific's largest planned project at about 390 megawatts of power. It's "utilizing the majority of extra system capacity" in the city, wrote a utility executive in a January email seen by Bloomberg. Any additional large power users will exacerbate overloads on the grid, the executive added. "When fully built out, it will host one of the largest GPU clusters in North America," Core Scientific Chief Executive Officer Adam Sullivan said of the site during a May call. "Denton is a flagship facility."

The report notes that Texas could face electricity shortages as soon as 2026 due to surging power demand from data centers, oil and gas operations, and crypto mining.

Hackers have stolen hundreds of millions of dollars from cryptocurrency holders and disrupted major retailers by targeting outsourced call centers used by American corporations to reduce costs, WSJ reported Thursday. The attackers exploit low-paid call center workers through bribes and social engineering to bypass two-factor authentication systems protecting bank accounts and online portals.

Coinbase faces potential losses of $400 million after hackers compromised data belonging to 97,000 customers by bribing call center workers in India with payments of $2,500. The criminals also used malicious tools that exploited vulnerabilities in Chrome browser extensions to collect customer data in bulk.

TaskUs, which handled Coinbase support calls, shut down operations at its Indore, India facility and laid off 226 workers. Retail attacks targeted Marks & Spencer and Harrods with hackers impersonating corporate executives to pressure tech support workers into providing network access. The same technique compromised MGM Resorts systems in 2023. Call center employees typically possess sensitive customer information including account balances and recent transactions that criminals use to masquerade as legitimate company representatives.

It's a nonprofit that's provide hosting for the Linux Foundation, the Apache Software Foundation, Drupal, Firefox, and 160 other projects — delivering nearly 430 terabytes of information every month. (It's currently hosting Debian, Fedora, and Gentoo Linux.) But hosting only provides about 20% of its income, with the rest coming from individual and corporate donors (including Google and IBM). "Over the past several years, we have been operating at a deficit due to a decline in corporate donations," the Open Source Lab's director announced in late April.

It's part of the CS/electrical engineering department at Oregon State University, and while the department "has generously filled this gap, recent changes in university funding makes our current funding model no longer sustainable. Unless we secure $250,000 in committed funds, the OSL will shut down later this year."

But "Thankfully, the call for support worked, paving the way for the OSU Open Source Lab to look ahead, into what the future holds for them," reports the blog It's FOSS.

"Following our OSL Future post, the community response has been incredible!" posted director Lance Albertson. "Thanks to your amazing support, our team is funded for the next year. This is a huge relief and lets us focus on building a truly self-sustaining OSL." To get there, we're tackling two big interconnected goals:

1. Finding a new, cost-effective physical home for our core infrastructure, ideally with more modern hardware.
2. Securing multi-year funding commitments to cover all our operations, including potential new infrastructure costs and hardware refreshes.


Our current data center is over 20 years old and needs to be replaced soon. With Oregon State University evaluating the future of this facility, it's very likely we'll need to relocate in the near future. While migrating to the State of Oregon's data center is one option, it comes with significant new costs. This makes finding free or very low-cost hosting (ideally between Eugene and Portland for ~13-20 racks) a huge opportunity for our long-term sustainability. More power-efficient hardware would also help us shrink our footprint.

Speaking of hardware, refreshing some of our older gear during a move would be a game-changer. We don't need brand new, but even a few-generations-old refurbished systems would boost performance and efficiency. (Huge thanks to the Yocto Project and Intel for a recent hardware donation that showed just how impactful this is!) The dream? A data center partner donating space and cycled-out hardware. Our overall infrastructure strategy is flexible. We're enhancing our OpenStack/Ceph platforms and exploring public cloud credits and other donated compute capacity. But whatever the resource, it needs to fit our goals and come with multi-year commitments for stability. And, a physical space still offers unique value, especially the invaluable hands-on data center experience for our students....

[O]ur big focus this next year is locking in ongoing support — think annualized pledges, different kinds of regular income, and other recurring help. This is vital, especially with potential new data center costs and hardware needs. Getting this right means we can stop worrying about short-term funding and plan for the future: investing in our tech and people, growing our awesome student programs, and serving the FOSS community. We're looking for partners, big and small, who get why foundational open source infrastructure matters and want to help us build this sustainable future together.
The It's FOSS blog adds that "With these prerequisites in place, the OSUOSL intends to expand their student program, strengthen their managed services portfolio for open source projects, introduce modern tooling like Kubernetes and Terraform, and encourage more community volunteers to actively contribute."

Thanks to long-time Slashdot reader I'm just joshin for suggesting the story.

Yahoo Finance shares an interesting prediction. Amazon has an "under-the-radar robot push" that "could boost its profit margins big-time, Morgan Stanley managing director Brian Nowak said." Nowak said Amazon has quietly developed six significant next-generation fulfillment centers in the past three years that bring automation front and center... Amazon now has industrial robots that can increase efficiencies across the storage, inventory management, pick and packing, and sorting order fulfillment processes.

Fulfillment costs make up about 20% of Amazon's retail revenue, so he reasoned that automation could have a significant impact on long-term operating profit potential. Nowak says if 30% to 40% of Amazon's US units were fulfilled through next-generation robotics-enabled warehouses by 2030, it could lead to $10 billion-plus of savings... The investments in robots may already be paying off. Amazon's North America retail operating margins on a trailing 12-month basis have risen for five straight quarters. North America operating margins improved to 6.2% from 4.6% a year ago.
Nowak made the remarks on a Yahoo Finance podcast (at the top of their article) after touring one of Amazon's robot-enhanced sites in Louisiana. He believes robotics can drive down Amazon's costs compared to other retailers like Target (which he sees as lagging behind Amazon on robotics).

Meanwhile workers at an Amazon facility in North Carolina held a vote Saturday on whether to unionize. But roughly 75% of the workers voted against unionization.

An anonymous reader quotes a report from the Boston Globe: Every weekday morning at 8:30, Preston Thorpe makes himself a cup of instant coffee and opens his laptop to find the coding tasks awaiting his seven-person team at Unlocked Labs. Like many remote workers, Thorpe, the nonprofit's principal engineer, works out in the middle of the day and often stays at his computer late into the night. But outside Thorpe's window, there's a soaring chain-link fence topped with coiled barbed wire. And at noon and 4 p.m. every day, a prison guard peers into his room to make sure he's where he's supposed to be at the Mountain View Correctional Facility in Charleston, Maine, where he's serving his 12th year for two drug-related convictions in New Hampshire, including intent to distribute synthetic opioids.

Remote work has spread far and wide since the pandemic spurred a work-from-home revolution of sorts, but perhaps no place more unexpectedly than behind prison walls. Thorpe is one of more than 40 people incarcerated in Maine's state prison system who have landed internships and jobs with outside companies over the past two years -- some of whom work full time from their cells and earn more than the correctional officers who guard them. A handful of other states have also started allowing remote work in recent years, but none have gone as far as Maine, according to the Alliance for Higher Education in Prison, the nonprofit leading the effort.

Unlike incarcerated residents with jobs in the kitchen or woodshop who earn just a few hundred dollars a month, remote workers make fair-market wages, allowing them to pay victim restitution fees and legal costs, provide child support, and contribute to Social Security and other retirement funds. Like inmates in work-release programs who have jobs out in the community, 10 percent of remote workers' wages go to the state to offset the cost of room and board. All Maine DOC residents get re-entry support for housing and job searches before they're released, and remote workers leave with even more: up-to-date resumes, a nest egg -- and the hope that they're less likely to need food or housing assistance, or resort to crime to get by.

This week a Florida-based Bitcoin-tech company named MARA Holdings announced it had bought a 114-megawatt Texas wind farm, reports Chron.com, "and will subsequently take it off the power grid and use it to energize its mining operations."

MARA's CEO tells the site they're "leveraging renewable resources that would have otherwise been curtailed" while "reducing our bitcoin production costs through vertical integration, and demonstrating MARA's commitment to environmental stewardship." The wind farms were not a part of the Electric Reliability Council of Texas (ERCOT) grid, but instead they were located within the Southwest Power Pool, which manages the market for the central U.S., including but not limited to most or parts of Oklahoma, Kansas, Nebraska, South Dakota and North Dakota... A 114-MW facility could power somewhere between 20,000 and 100,000 homes, depending on who you ask...

Historically, the facilities use up a lot of power and have generated backlash from neighbors who have complained about the noise of the machines inside. Texas has been a haven for cryptocurrency tech companies, primarily because of the state's space, deregulated power market and friendly business climate. Two weeks ago, the Public Utilities Commission adopted a rule requiring crypto and other virtual currency miners within the ERCOT grid to register their locations, ownership information and electricity demands, to further ensure that they could be watchful of this emerging source of energy consumption.
"Crypto mining operations currently consume around 2.3 percent of US electricity, and it requires roughly 155,000kWh to mine one Bitcoin," notes the site Data Centre Dynamics. This is the second off-grid power deal MARA has signed over the last few months. In October, it launched a 25MW micro data center operation across oil wellheads in Texas and North Dakota. The data center will be powered exclusively by excess natural gas from oilfield production that would have otherwise been flared. The operation will be distributed across wellheads in Texas and North Dakota, with operational status expected by January 2025.
Some context from Bloomberg: A few years ago Bitcoin miners took part in a global scramble for electricity to power their specialized computers... But the rise of AI, with its insatiable demand for electricity, dwarfed the needs of crypto and upended energy markets worldwide. Miners must now compete with much-larger tech firms for connections to electrical grids and power contracts. "Bitcoin miners are being forced to go look at marginal generation," said [MARA CEO Fred] Thiel. "The AI guys can afford to pay a much higher amount for energy than a Bitcoin miner"... MARA's plan to mine only when the wind is blowing makes economic sense because its mine will house last-generation computers that would otherwise have been retired, Thiel said.
"Thiel said he'd be interested to potentially buy more wind farms over time."

Slashdot reader echo123 shared this report from Ars Technica: The NASA program to develop a new upper stage for the Space Launch System rocket is seven years behind schedule and significantly over budget, a new report from the space agency's inspector general finds. However, beyond these headline numbers, there is also some eye-opening information about the project's prime contractor, Boeing, and its poor quality control practices... "We found an array of issues that could hinder SLS Block 1B's readiness for Artemis IV including Boeing's inadequate quality management system, escalating costs and schedules, and inadequate visibility into the Block 1B's projected costs," states the report, signed by NASA's deputy inspector general, George A. Scott.

There are some surprising details in the report about Boeing's quality control practices at the Michoud Assembly Facility in southern Louisiana, where the Exploration Upper Stage is being manufactured. Federal observers have issued a striking number of "Corrective Action Requests" to Boeing. "According to Safety and Mission Assurance officials at NASA and DCMA officials at Michoud, Boeing's quality control issues are largely caused by its workforce having insufficient aerospace production experience," the report states. "The lack of a trained and qualified workforce increases the risk that the contractor will continue to manufacture parts and components that do not adhere to NASA requirements and industry standards."

This lack of a qualified workforce has resulted in significant program delays and increased costs. According to the new report, "unsatisfactory" welding operations resulted in propellant tanks that did not meet specifications, which directly led to a seven-month delay in the program.

Last week America's energy secretary cheered the startup of a fourth nuclear reactor at a Georgia power plant, calling it "the largest producer of clean energy, and the largest producer of electricity in the United States" after a third reactor was started up there in December.

From the U.S. Energy Department's transcript of the speech: Each year, Units 3 and 4 are going to produce enough clean power to power 1 million homes and businesses, enough energy to power roughly 1 in 4 homes in Georgia. Preventing 10 million metric tons of carbon dioxide pollution annually. That, by the way, is like planting more than 165 million trees every year!

And that's not to mention the historic investments that [electric utility] Southern has made on the safety front, to ensure this facility meets — and exceeds — the highest operating standards in the world....

To reach our goal of net zero by 2050, we have to at least triple our current nuclear capacity in this country. That means we've got to add 200 more gigawatts by 2050. Okay, two down, 198 to go! In building [Unit] 4, we've solved our greatest design challenges. We've stood up entire supply chains.... And so it's time to cash in on our investments by building more. More of these facilities. The Department of Energy's Loan Programs Office stands ready to help, with hundreds of billions of dollars in what we call Title 17 loans... Since the President signed the Inflation Reduction Act and the Bipartisan Infrastructure Law, companies across the nation have announced 29 new or expanded nuclear facilities — across 16 states — representing about 1,600 potential new jobs. And the majority of those projects will expand the domestic uranium production and fuel fabrication, strengthening these critical supply chains...

Bottom line is, in short, we are determined to build a world-class nuclear industry in the United States, and we're putting our money where our mouth is.
America's Energy Secretary told the Washington Post that "Whether it happens through small modular reactors, or AP1000s, or maybe another design out there worthy of consideration, we want to see nuclear built." The Post notes the Energy department gave a $1.5 billion loan to restart a Michigan power plant which was decommissioned in 2022. "It would mark the first time a shuttered U.S. nuclear plant has been reactivated."

"But in this country with 54 nuclear plants across 28 states, restarting existing reactors and delaying their closure is a lot less complicated than building new ones." When the final [Georgia] reactor went online at the end of April, the expansion was seven years behind schedule and nearly $20 billion over budget. It ultimately cost more than twice as much as promised, with ratepayers footing much of the bill through surcharges and rate hikes...

Administration officials say the country has no choice but to make nuclear power a workable option again. The country is fast running short on electricity, demand for power is surging amid a boom in construction of data centers and manufacturing plants, and a neglected power grid is struggling to accommodate enough new wind and solar power to meet the nation's needs...

As the administration frames the narrative of the plant as one of perseverance and innovation that clears a path for restoring U.S. nuclear energy dominance, even some longtime boosters of the industry question whether this country will ever again have a vibrant nuclear energy sector. "It is hard for me to envision state energy regulators signing off on another one of these, given how badly the last ones went," said Matt Bowen, a nuclear scholar at the Center on Global Energy Policy at Columbia University, who was an adviser on nuclear energy issues in the Obama administration.
The article notes there are 19 AP1000 reactors (the design used at the Georgia plant) in development around the world. "None of them are being built in the United States."

An anonymous reader quotes a report from Ars Technica: When used to generate power or move vehicles, fossil fuels kill people. Particulates and ozone resulting from fossil fuel burning cause direct health impacts, while climate change will act indirectly. Regardless of the immediacy, premature deaths and illness prior to death are felt through lost productivity and the cost of treatments. Typically, you see the financial impacts quantified when the EPA issues new regulations, as the health benefits of limiting pollution typically dwarf the costs of meeting new standards. But some researchers from Lawrence Berkeley National Lab have now done similar calculations -- but focusing on the impact of renewable energy. Wind and solar, by displacing fossil fuel use, are acting as a form of pollution control and so should produce similar economic benefits. Do they ever. The researchers find that, in the U.S., wind and solar have health and climate benefits of over $100 for every Megawatt-hour produced, for a total of a quarter-trillion dollars in just the last four years. This dwarfs the cost of the electricity they generate and the total of the subsidies they received. [...]

As a result, the environmental and health benefits of wind in 2022 are estimated as being $143 for each Mw-hr, with solar providing $100/Mw-hr in benefits. Given the amount of power generated by wind and solar that year, that works out to a total of $62 billion and $12 billion, respectively. For the entire 2019-2022 period, they total up to $250 billion. Due to the uncertainties in various estimates, the researchers estimate that the real value for wind is somewhere between $91 and $183 per Mw-hr, with solar having a proportionate uncertainty. For comparison, they note that the unsubsidized costs of the electricity produced by wind and solar range from $20 to $60 per Mw-hr, depending on where the facility is sited. So, in some ways, the companies that own these plants are only receiving a very small fraction of the benefits of their operation. Wind and solar do receive subsidies, but even the most generous ones provided by the Inflation Reduction Act max out below $35/Mw-hr -- again, far less than the health and environmental benefits. The researchers note that most of these benefits (about 75 percent) come from the reduction in carbon dioxide emissions. Still, the nitrogen and sulfur emissions reductions were also substantial: They displaced the equivalent of roughly 20 percent of the power sector's total emissions of these chemicals. That translates into avoiding about 1,400 premature deaths in 2022 alone. The researchers acknowledge a number of limitations to their work. "One big one is that they don't include distributed solar at all, meaning their totals for that form of production are a significant underestimate," reports Ars, noting that the Energy Information Agency estimates that, in the U.S., distributed solar accounts for over 30 percent of total solar production. "It also, as mentioned, doesn't account for the use of storage such as batteries, which are increasingly used to offset the tail-off in solar production in the evenings."

"In addition, their work doesn't account for the intermittency of renewable power sources, which can sometimes result in the use of less efficient fossil fuel plants and so offset some of these benefits. The drop of wind and solar prices are also influencing decisions on what types of fossil fuel plants are getting built, disfavoring coal and increasing investments in natural gas plants that can respond quickly to changes in renewable output. Over the long term, this will result in additional benefits that can't be captured by this sort of short-term analysis."

The study has been published in the journal Cell Reports Sustainability.

Oakland, California is now home to "the first commercial hydrogen fuel station for big-rig trucks in the United States," according to the Los Angeles Times — serving 30 hydrogen fuel-cell trucks.

The newspaper says the facility "could mark the start of a nationwide network for fuel-cell truck refueling. It could also flop." Hydrogen fuel is expensive — as much as four times more expensive than gasoline or diesel fuel. The fuel cells, which drive electric motors to drive the truck, are enormously expensive as well.... The vehicles themselves are expensive too. Both battery electric and hydrogen fuel-cell trucks can cost three times as much or more than a $120,000 diesel truck. Those buying the trucks can qualify for state and federal subsidies to make up most of the upfront costs.
But government regulations may spark some demand: New diesel truck sales will be outlawed in California by 2036. Only zero-tailpipe-emission new trucks will be allowed. Already, zero-emission requirements are in place for trucks that enter ocean ports. And only two technologies are available to achieve that goal: battery electric trucks and hydrogen fuel-cell trucks. "We believe a good portion of those will be hydrogen vehicles," said Matt Miyasato, chief of public policy for hydrogen fuel distributor FirstElement Fuel. FirstElement, through its True Zero brand fueling stations, is the largest hydrogen vehicle fuel distributor in the U.S...

Battery electric is gaining a strong foothold in the medium-sized delivery truck market, but hydrogen could have a leg up for long-haul trucking. While a fuel cell is comparable in size to a diesel engine, a battery big enough for long-haul trucks adds weight and size and cuts down on the total freight load the truck can deliver. And while an electric truck battery can take hours to recharge, the refill time for hydrogen is more comparable to filling up with diesel fuel.

An anonymous reader shared this report from CNN: On a slice of the ocean front in west Singapore, a startup is building a plant to turn carbon dioxide from air and seawater into the same material as seashells, in a process that will also produce "green" hydrogen — a much-hyped clean fuel.

The cluster of low-slung buildings starting to take shape in Tuas will become the "world's largest" ocean-based carbon dioxide removal plant when completed later this year, according to Equatic, the startup behind it that was spun out of the University of California at Los Angeles. The idea is that the plant will pull water from the ocean, zap it with an electric current and run air through it to produce a series of chemical reactions to trap and store carbon dioxide as minerals, which can be put back in the sea or used on land... The $20 million facility will be fully operational by the end of the year and able to remove 3,650 metric tons of carbon dioxide annually, said Edward Sanders, chief operating officer of Equatic, which has partnered with Singapore's National Water Agency to construct the plant. That amount is equivalent to taking roughly 870 average passenger cars off the road. The ambition is to scale up to 100,000 metric tons of CO2 removal a year by the end of 2026, and from there to millions of metric tons over the next few decades, Sanders told CNN. The plant can be replicated pretty much anywhere, he said, stacked up in modules "like lego blocks...."

The upfront costs are high but the company says it plans to make money by selling carbon credits to polluters to offset their pollution, as well as selling the hydrogen produced during the process. Equatic has already signed a deal with Boeing to sell it 2,100 metric tons of hydrogen, which it plans to use to create green fuel, and to fund the removal of 62,000 metric tons of CO2.
There's other projects around the world attempting ocean-based carbon renewal, CNN notes. "Other projects include sprinkling iron particles into the ocean to stimulate CO2-absorbing phytoplankton, sinking seaweed into the depths to lock up carbon and spraying particles into marine clouds to reflect away some of the sun's energy." But carbon-removal projects are controversial, criticized for being expensive, unproven at scale and a distraction from policies to cut fossil fuels. And when they involve the oceans — complex ecosystems already under huge strain from global warming — criticisms can get even louder. There are "big knowledge gaps" when it comes to ocean geoengineering generally, said Jean-Pierre Gatusso, an ocean scientist at the Sorbonne University in France. "I am very concerned with the fact that science lags behind the industry," he told CNN.

Tobias Mann reports via The Register: The land surrounding a nuclear power plant might not sound like prime real estate, but as more bit barns seek to trim costs, it's poised to become a rather hot commodity. All datacenters are energy-hungry but with more watt-greedy AI workloads on the horizon, nuclear power has fresh appeal, especially for hyperscalers. Such a shift in power also does wonders for greenwashing narratives around net-zero operations. While not technically renewable, nuclear power does have the benefit of being carbon-free, not to mention historically reliable -- with a few notable exceptions of course. All of these are purported benefits cited by startup NE Edge, which has been fighting for more than a year to be able to build a pair of AI datacenters adjacent to a 2GW Millstone nuclear power plant in Waterford, Connecticut.

According to the Hartford Courant, NE Energy has secured $1.6 billion to construct the switching station and bit barns, which will span 1.2 million square feet in total. NE Energy will reportedly spend an equivalent sum on between 25,000 and 35,000 servers. Considering the price of GPU systems from Nvidia, AMD, and Intel, we suspect that those figures probably refer to the number of GPUs. We've asked NE Edge for more information. NE Energy has faced local challenges getting the project approved because residents are concerned the project would end up increasing the cost of electricity. The facilities will reportedly consume as much as 13 percent of the plant's output. The project's president Thomas Quinn attempted to quell concerns, arguing that by connecting directly to the plants, NE Energy will be able to negotiate prices that make building such a power hungry facility viable in Connecticut. NE Energy has also committed to paying a 12.08 percent premium to the town on top of what it pays Dominion for power, along with other payments said to total more than $1 billion over the next 30 years. But after initially denying the sale of land to NE Edge back in January over a lack of information regarding the datacenter project, it's reported that the town council has yet to tell the company what information it is after.

An anonymous reader shares a report: About 6,000 older Bitcoin mining machines in the US will soon be idled and sent to a warehouse in Colorado Springs where they'll be refreshed and resold to buyers overseas looking to profit from mining in lower-cost environs. Wholesaler SunnySide Digital operates the 35,000 square-foot facility taking in the equipment from a mining client. The outdated machines are among several hundred-thousand it expects to receive and refurbish around a major quadrennial update in the Bitcoin blockchain.

Known as the halving, the late April event will slash the reward that's the main revenue stream for miners, who will try to lessen the impact by upgrading to the latest and most efficient technology. With electricity the biggest expense, mining companies including publicly traded giants Marathon Digital Holdings and Riot Platforms need to lower usage costs to maintain a positive margin. Their older computers may still bring a profit, just not likely in the US.

Some 600,000 S19 series computers, which account for a majority of machines currently in use, are moving out of the US mostly to Africa and South America, according to an estimate by Ethan Vera, chief operating officer at crypto-mining services and logistics provider Luxor Technology in Seattle. In Bitcoin mining, specialized machines are used to validate transactions on the blockchain and earn operators a fixed token reward. Anonymous Bitcoin creator Satoshi Nakamoto baked in the once-every-four-years halving to maintain the hard cap of 21 million tokens. Next month's event is the fourth since 2012 and the reward will drop to 3.125 Bitcoin from 6.25 now.

After producing a nuclear fusion reaction last year that released more energy than it used, scientists at the National Ignition Facility at the Lawrence Livermore National Laboratory in California (LLNL) say they have successfully replicated the process at least three times this year. "This marks another significant step in what could one day be an important solution to the global climate crisis, driven primarily by the burning of fossil fuels," reports CNN. The announcement appears in a December report (PDF) from the LLNL. From the report: After making their historic net energy gain last year, the next important step was to prove the process could be replicated. Brian Appelbe, a research fellow from the Centre for Inertial Fusion Studies at Imperial College London, said the ability to replicate demonstrates the "robustness" of the process, showing it can be achieved even when conditions such as the laser or fuel pellet are varied. Each experiment also offers an opportunity to study the physics of ignition in detail, Appelbe told CNN. "This provides valuable information to the scientists in addressing the next challenge to be overcome: how to maximize the energy that can be obtained."

There are different ways of creating energy from fusion, but at NIF, scientists fire an array of nearly 200 lasers at a pellet of hydrogen fuel inside a diamond capsule the size of a peppercorn, itself inside a gold cylinder. The lasers heat up the cylinder's outside, creating a series of very fast explosions, generating large amounts of energy collected as heat. The energy produced in December 2022 was small -- it took around 2 megajoules to power the reaction, which released a total of 3.15 megajoules, enough to boil around 10 kettles of water. But it was sufficient to make it a successful ignition and to prove that laser fusion could create energy.

Since then, the scientists have done it several more times. On July 30, the NIF laser delivered a little over 2 megajoules to the target, which resulted in 3.88 megajoules of energy -- their highest yield achieved to date, according to the report. Two subsequent experiments in October also delivered net gains. "These results demonstrated NIF's ability to consistently produce fusion energy at multi-megajoule levels," the report said. There is still a very long way to go, however, until nuclear fusion reaches the scale needed to power electric grids and heating systems. The focus now is on building on the progress made and figuring out how to dramatically scale up fusion projects and significantly bring down costs.

Thousands of people in Oregon have signed up to experience tripping on magic mushrooms at America's first license psilocybin service center. The Associated Press reports: Epic Healing Eugene -- America's first licensed psilocybin service center -- opened in June, marking Oregon's unprecedented step in offering the mind-bending drug to the public. The center now has a waitlist of more than 3,000 names, including people with depression, PTSD or end-of-life dread. No prescription or referral is needed, but proponents hope Oregon's legalization will spark a revolution in mental health care. The Oregon Psilocybin Services Section, charged with regulating the state's industry, has received "hundreds of thousands of inquiries from all over the world," Angela Allbee, the agency's manager, said in an interview. "So far, what we're hearing is that clients have had positive experiences," she said.

First, customers must have a preparation session with a licensed facilitator who stays with clients as they experience the drug. The facilitator can deny access to those who have active psychosis, thoughts of harming anyone, or who have taken lithium, which is used to treat mania, in the past month. The clients can't buy mushrooms to go, and they must stay at the service center until the drug wears off. Oregon Psilocybin Services spent two years establishing regulations and began accepting license applications in January. There are now 10 licensed service centers, four growers, two testing labs and dozens of facilitators. [...] The report notes that costs can be high, with some clients paying over $2,000 and annual licenses for service centers and growers costing $10,000, with a half-price discount for veterans.

As for doses, state regulations allow up to 50 milligrams but it will ultimately depend on the facility and client. One of the facility's first clients took 35 milligrams and described seeing a "kind of infinite-dimension fractal that just kept turning and twisting."

When it comes to reducing American dependence on Taiwan, the TSMC Arizona chip plant will be little more than a useless paperweight, says an analyst at one chip research firm. "The TSMC Arizona fab is effectively a paperweight in any geopolitical tension or war [with China over Taiwan] due to the fact that it still requires sending the chips back to Taiwan for packaging," said Dylan Patel, chief analyst at SemiAnalysis. 9to5Mac reports: A new report in The Information says while Apple chips may be made in the U.S., they will still need to be sent back to Taiwan before they get anywhere near an Apple device: "The Arizona factory -- which has been a focal point of the Biden plan and will cost $40 billion to build -- will do little to make the U.S. self-reliant in chips. That's because many advanced chips made in Arizona for Apple or other customers such as Nvidia, AMD and Tesla will still require assembly in Taiwan in a process known as packaging, according to interviews with multiple TSMC engineers and former Apple employees."

Given that TSMC has been struggling even to build a chip fab for older tech, there seems no prospect that it would ever attempt to set up chip packaging facilities in the U.S. "Building this type of facility is a huge expenditure of [capital], time, and effort, and it does not seem likely that TSMC will want to do this anytime soon in the desert in Arizona, particularly given all the problems the firm has encountered with construction, costs and personnel so far," said Paul Triolo, senior vice president for China at consultancy DGA-Albright Stonebridge Group.

"France and Germany lead the camps in disagreeing on the future of nuclear in Europe," write two climate policy journalists. On the Energy Post blog they explore why — citing energy experts and politicians.

Germany "ultimately completed its nuclear exit in April 2023," while France "has the highest share of nuclear in the energy mix of any country in the world." [A] major concern is that more nuclear means less renewables, at a time when wind and solar need all the scale they can get... In a joint attempt to provide greater technical clarity on the nuclear power debate, French think tank IDDRI and German Agora Energiewende set out in 2018 to understand how nuclear energy will influence the transformation of energy systems in both countries. They found that if a high share of coal or nuclear based conventional power capacity stays online in both countries, this will likely to delay the time when market prices allow renewable power operators to cover their production costs and run the operations at a profit. They also found that exporting surplus electricity with conventional plants bites into renewable power investments abroad. At the same time, the growing share of renewables would eventually render most conventional plants unprofitable. "In order to avoid stranded assets, it is essential to gradually reduce conventional capacities," the bi-national report concluded...

Xavier Moreno, president of French think tank Ecological Realities and Energy Mix Study Circle (Cereme) and former vice president of French utility company Suez, said the all-renewables approach was complicated by a lack of viable electricity storage technologies. "Technically speaking, it would be necessary to store up to 20 percent to be able to smoothen renewable power supply." Those who believe that this will be possible through a combination of different storage options are chasing "a dream," Moreno argued.
The issue comes up when trading power in Europe's integrated energy market: should gate closure times be based on a decentralised, flexible renewables-based system, or a centralised grid based on nuclear baseloads? Rainer Hinrichs-Rahlwes, European policy expert for the German Renewable Energy Federation lobby group, says "Nuclear power plants and their inflexible output can cause grid congestion, the opposite of what is needed to accommodate large shares of wind and solar in a modern and flexible grid system."

The article notes that France plans to eliminate coal use by 2038, and already has one of the lowest emissions per head of any rich country. But "In mid-2023, 800 French scientists warned against the risks of the country's new nuclear programme, pointing to unresolved questions of radioactive waste management, which remain largely unresolved in most of the EU, including in France. The scientists also warned against risks of accidental contamination or meltdown."

American retailers see opportunities in the primary-care business. From a report: With his long white coat, stethoscope, genially soothing manner and wonky eagerness to discuss "population health management" and "patient-centred" medicine, Ronald Searcy seems the Platonic ideal of a primary-care doctor. The most unusual thing about him is where he works: a compact facility complete with examination rooms, dentist's office, phlebotomy lab and X-ray room tucked into a Walmart in north-west Arkansas. Since 2019, Walmart has opened 32 of these "health centres" in five states; by the end of next year it plans to more than double that number, and expand into two more states. Walmart is not the only big company expanding its medical offerings.

[...] What do these companies see in the medical business? The answer, befitting America's Byzantine and rent-filled health-care system, is both simple and complex. The simple answer is money. Americans spend a stunning amount of it on health: roughly 18% of GDP in 2021, far exceeding the rich-country average of about 10% and more than double the ratio of some, such as South Korea, with healthier and longer-lived populations. Americans' spending is forecast to rise by 5.4% per year over the next eight years, outpacing economic growth and accounting for almost 20% of GDP by 2031. The bulk of that spending will come from Medicaid and Medicare, federal programmes that cover health-care costs for, respectively, poor people and over-65s. The complex part reflects changes in how insurers, including Medicaid and Medicare, pay for coverage; as well as changes in how consumers are willing to get it.
