YouTube Plans Lower-Priced, Ad-Free Version of Paid Video Tier 48

According to Bloomberg, YouTube plans to introduce a lower-priced, ad-free version of its paid video service. From the report: The package, dubbed "premium lite," will be announced soon in the US, Australia, Germany and Thailand, according to a person familiar with the plans. The service will target viewers who primarily want to watch programs other than music videos. While YouTube may be best known for the free videos uploaded by users, the company also offers a variety of paid services. YouTube Premium is a $13.99-a-month package in the US that lets subscribers watch everything on the service, including music videos, without ads.

"As part of our commitment to provide our users with more choice and flexibility, we've been testing a new YouTube Premium offering with most videos ad-free in several of our markets," a YouTube spokesperson said in a statement. "We're hoping to expand this offering to even more users in the future with our partners' support."

Rare Genetic Disorder Treated in Womb For the First Time (nature.com) 30

A two-and-a-half-year-old girl shows no signs of a rare genetic disorder, after becoming the first person to be treated for the motor-neuron condition while in the womb. Nature: The child's mother took the gene-targeting drug during late pregnancy, and the child continues to take it. The "baby has been effectively treated, with no manifestations of the condition," says Michelle Farrar, a paediatric neurologist at UNSW Sydney in Australia. The results were published in the New England Journal of Medicine yesterday. The child was conceived with a genetic condition known as spinal muscular atrophy, which affects motor neurons that control movement, and leads to progressive muscle weakening.

About one in every 10,000 births have some form of the condition -- making it a leading genetic cause of death in infants and children. In its most severe form, as in the case of this child, individuals lack both copies of the SMN1 gene, and have only one or two copies of a neighbouring gene, SMN2, that partially compensates for that deficiency. As a result, the body does not produce enough of the protein required for maintaining motor neurons in the spinal cord and brainstem. This protein is most important in the second and third trimesters, and the first few months of life. Babies with severe disease don't usually live past their third birthday.

DeepSeek Removed from South Korea App Stores Pending Privacy Review (france24.com) 3

Today Seoul's Personal Information Protection Commission "said DeepSeek would no longer be available for download until a review of its personal data collection practices was carried out," reports AFP. A number of countries have questioned DeepSeek's storage of user data, which the firm says is collected in "secure servers located in the People's Republic of China"... This month, a slew of South Korean government ministries and police said they blocked access to DeepSeek on their computers. Italy has also launched an investigation into DeepSeek's R1 model and blocked it from processing Italian users' data. Australia has banned DeepSeek from all government devices on the advice of security agencies. US lawmakers have also proposed a bill to ban DeepSeek from being used on government devices over concerns about user data security.
More details from the Associated Press: The South Korean privacy commission, which began reviewing DeepSeek's services last month, found that the company lacked transparency about third-party data transfers and potentially collected excessive personal information, said Nam Seok [director of the South Korean commission's investigation division]... A recent analysis by Wiseapp Retail found that DeepSeek was used by about 1.2 million smartphone users in South Korea during the fourth week of January, emerging as the second-most-popular AI model behind ChatGPT.

Trust in AI is Much Higher in China Than in the US (axios.com) 67

Trust in AI is significantly higher in China than in the United States, according to new data from the Edelman Trust Barometer. Axios: Edelman's latest research found that 72% of people in China trust AI, compared with just 32% in the United States. Not only is trust higher in China, it's higher in much of the developing world than it is in the United States, according to Edelman's research.

Trust in AI was highest in India, at 77%, followed by Nigeria at 76%, Thailand at 73% and then China. Only six of the surveyed countries ranked lower than the U.S. in their trust in the new technology: Canada (30%), Germany (29%), the Netherlands (29%), United Kingdom (28%), Australia (25%) and Ireland (24%). Globally, 52% of men said they trusted AI vs. 46% of women, with younger people significantly more trusting of the technology than older folks. In the U.S., AI was trusted more by Democrats (38%) than Republicans (34%) or independents (23%). Higher-income respondents were also more trusting (51%) than those with middle (45%) or low (36%) incomes.

Are PhDs Losing Their Lustre? Why Fewer Students Are Enrolling in Doctoral Degrees (nature.com) 110

Several countries are seeing a decline in PhD enrollments as high living costs, stagnant stipends and limited job prospects deter students from pursuing doctoral degrees. Australia recorded an 8% drop in domestic PhD enrollments from 2018 to 2023 despite population growth of 7%, while Japan's numbers fell to 15,014 in 2023 from 18,232 in 2003, data from education authorities showed.

PhD stipends have failed to keep pace with rising costs. In Australia, doctoral students receive about A$32,000 ($20,000) annually, below minimum wage, while Brazil only increased its graduate grants last year after a decade-long freeze.

The trend reflects broader concerns about academic careers becoming increasingly precarious, said Claudia Sarrico, a project lead at the Organisation for Economic Co-operation and Development in Paris. Some countries are taking steps to address the issue. Japan's education ministry plans to provide additional funding for doctoral students, while Brazil's 40% increase in graduate grants in 2023 has led to a slight uptick in enrollments.

After Copilot Trial, Government Staff Rated Microsoft's AI Less Useful Than Expected (theregister.com) 31

An anonymous reader shares a report: Australia's Department of the Treasury has found that Microsoft's Copilot can easily deliver return on investment, but staff exposed to the AI assistant came away from the experience less confident it will help them at work.

The Department conducted a 14-week trial of Microsoft 365 Copilot during 2024 and asked for volunteers to participate. 218 put up their hands and then submitted to surveys about their experiences using Microsoft's AI helpers. Those surveys are the basis of an evaluation report published on Tuesday. The report reveals that after the trial participants rated Copilot less useful than they hoped it would be, as it was applicable to fewer workloads than they hoped would be the case.

Workers' views on Copilot's ability to improve their work also fell. Usage of Copilot was lower than expected, with most participants using it two or three times a week, or less. reported using Copilot 2-3 times per week or less. Treasury thinks it probably set unrealistically high expectations before the trial, and noted that participants often suggested extra training would be valuable.

AUKUS Blasts Holes In LockBit's Bulletproof Hosting Provider (theregister.com) 11

The US, UK, and Australia (AUKUS) have sanctioned Russian bulletproof hosting provider Zservers, accusing it of supporting LockBit ransomware operations by providing secure infrastructure for cybercriminals. The sanctions target Zservers, its UK front company XHOST Internet Solutions, and six individuals linked to its operations. The Register reports: Headquartered in Barnaul, Russia, Zservers provided BPH services to a number of LockBit affiliates, the three nations said today. On numerous occasions, affiliates purchased servers from the company to support ransomware attacks. The trio said the link between Zservers and LockBit was established as early as 2022, when Canadian law enforcement searched a known LockBit affiliate and found evidence they had purchased infrastructure tooling almost certainly used to host chatrooms with ransomware victims.

"Ransomware actors and other cybercriminals rely on third-party network service providers like Zservers to enable their attacks on US and international critical infrastructure," said Bradley T Smith, acting under secretary of the Treasury for terrorism and financial intelligence. "Today's trilateral action with Australia and the United Kingdom underscores our collective resolve to disrupt all aspects of this criminal ecosystem, wherever located, to protect our national security." The UK's Foreign, Commonwealth & Development Office (FCDO) said additionally that the UK front company for Zservers, XHOST Internet Solutions, was also included in its sanctions list. According to Companies House, the UK arm was incorporated on January 31, 2022, although the original service was established in 2011 and operated in both Russia and the Netherlands. Anyone found to have business dealings with either entity can face criminal and civil charges under the Sanctions and Anti-Money Laundering Act 2018.

The UK led the way with sanctions, placing six individuals and the two entities on its list, while the US only placed two of the individuals -- both alleged Zservers admins -- on its equivalent. Alexander Igorevich Mishin and Aleksandr Sergeyevich Bolshakov, both 30 years old, were named by the US as the operation's heads. Mishin was said to have marketed Zservers to LockBit and other ransomware groups, managing the associated cryptocurrency transactions. Both he and Bolshakov responded to a complaint from a Lebanese company in 2023 and shut down an IP address used in a LockBit attack. The US said, however, it was possible that the pair set up a replacement IP address that LockBit could carry on using, while telling the Lebanese company that they complied with its request. The UK further sanctioned Ilya Vladimirovich Sidorov, Dmitry Konstantinovich Bolshakov (no mention of whether he is any relation to Aleksandr), Igor Vladimirovich Odintsov, and Vladimir Vladimirovich Ananev. Other than that they were Zservers employees and thus were directly or indirectly involved in attempting to inflict economic loss to the country, not much was said about either of their roles.

Trump Orders Treasury Secretary To Stop Minting Pennies 509

President Donald Trump has ordered Treasury Secretary Scott Bessent to halt penny production to cut government spending, according to a Truth Social post on Sunday. The U.S. Mint spent 3.69 cents to produce and distribute each penny last year, resulting in a $85.3 million loss on over three billion new pennies.

The one-cent coin accounts for more than half of all U.S. coin production despite having about 250 billion pieces already in circulation. Canada, Australia and several other countries have eliminated their lowest-denomination coins citing costs over recent decades.

Free 'T-Mobile Starlink' for Six Months Announced During Super Bowl. Also Available to Verizon and AT&T Customers 211

Today T-Mobile announced what they're calling "the next big thing in wireless" — T-Mobile Starlink. But the real surprise is "The beta is now open for absolutely everyone — yes, even Verizon and AT&T customers — to register for free access until July."

And, as they explained to Americans watching the Super Bowl, "If you can see the sky you're connected." Now in public beta, this breakthrough service, developed in partnership with Starlink, uses straight-out-of-a-sci-fi-movie satellite and mobile communications technology to help keep people connected — even you, Verizon and AT&T customers — in the more than 500,000 square miles of the country unreached by any carrier's earth-bound cell towers. That's nearly the size of two Texases...! The beauty of the service is its simplicity: users don't need to do anything out of the ordinary. When a user's cell phone gets out of range of a cell tower, the phone automatically connects to the T-Mobile Starlink network. No need to manually connect. Messages are sent and received just as they are today on a traditional network, even group texts and reactions. And it works on most smartphones from the last four years. It's not limited to a few smartphones or operating systems...

The beta is free until July at which point T-Mobile Starlink will be included at no extra cost on Go5G Next (including variations like Go5G Next 55+), T-Mobile's best plan. Business customers will also get T-Mobile Starlink at no extra cost on Go5G Business Next, first responder agencies on T-Priority plans and other select premium rate plans. T-Mobile customers on any other plan can add the service for $15/month per line. Through February, T-Mobile customers who have registered for the beta can secure a $10/month per line Early Adopter Discount, 33% off the full price.

AT&T and Verizon customers hate dead zones, too

When your service is amazing and different, you want as many people to try it as possible. T-Mobile is giving AT&T and Verizon customers the opportunity to try out T-Mobile Starlink satellite service on their existing phones... During the beta period, Verizon and AT&T customers can experience T-Mobile Starlink text messaging for free, and once the service launches in July, it will be available for $20/month per line... More details and consumer registration can be found here.

A Vision for Universal Coverage

As T-Mobile and Starlink continue to work towards eliminating mobile deadzones, the companies welcome wireless providers from around the world to join their growing alliance, which aims to provide reciprocal roaming for all participating carriers. So far, KDDI (Japan), Telstra (Australia), Optus (Australia), One NZ (New Zealand), Salt (Switzerland), Entel (Chile & Peru), Rogers (Canada) and Kyivstar (Ukraine) are among the providers that have signed on to join the cause and launch satellite-to-mobile technology.

The Enshittification Hall of Shame 249

In 2022, writer and activist Cory Doctorow coined the term "enshittification" to describe the gradual deterioration of a service or product. The term's prevalence has increased to the point that it was the National Dictionary of Australia's word of the year last year. The editors at Ars Technica, having "covered a lot of things that have been enshittified," decided to highlight some of the worst examples the've come across. Here's a summary of each thing mentioned in their report: Smart TVs: Evolved into data-collecting billboards, prioritizing advertising and user tracking over user experience and privacy. Features like convenient input buttons are sacrificed for pushing ads and webOS apps. "This is all likely to get worse as TV companies target software, tracking, and ad sales as ways to monetize customers after their TV purchases -- even at the cost of customer convenience and privacy," writes Scharon Harding. "When budget brands like Roku are selling TV sets at a loss, you know something's up."

Google's Voice Assistant (e.g., Nest Hubs): Functionality has degraded over time, with previously working features becoming unreliable. Users report frequent misunderstandings and unresponsiveness. "I'm fine just saying it now: Google Assistant is worse now than it was soon after it started," writes Kevin Purdy. "Even if Google is turning its entire supertanker toward AI now, it's not clear why 'Start my morning routine,' 'Turn on the garage lights,' and 'Set an alarm for 8 pm' had to suffer."

Portable Document Format (PDF): While initially useful for cross-platform document sharing and preserving formatting, PDFs have become bloated and problematic. Copying text, especially from academic journals, is often garbled or impossible. "Apple, which had given the PDF a reprieve, has now killed its main selling point," writes John Timmer. "Because Apple has added OCR to the MacOS image display system, I can get more reliable results by screenshotting the PDF and then copying the text out of that. This is the true mark of its enshittification: I now wish the journals would just give me a giant PNG."

Televised Sports (specifically cycling and Formula 1): Streaming services have consolidated, leading to significantly increased costs for viewers. Previously affordable and comprehensive options have been replaced by expensive bundles across multiple platforms. "Formula 1 racing has largely gone behind paywalls, and viewership is down significantly over the last 15 years," writes Eric Berger. "Major US sports such as professional and college football had largely been exempt, but even that is now changing, with NFL games being shown on Peacock, Amazon Prime, and Netflix. None of this helps viewers. It enshittifies the experience for us in the name of corporate greed."

Google Search: AI overviews often bury relevant search results under lengthy, sometimes inaccurate AI-generated content. This makes finding specific information, especially primary source documents, more difficult. "Google, like many big tech companies, expects AI to revolutionize search and is seemingly intent on ignoring any criticism of that idea," writes Ashley Belanger.

Email AI Tools (e.g., Gemini in Gmail): Intrusive and difficult to disable, these tools offer questionable value due to their potential for factual inaccuracies. Users report being unable to fully opt-out. "Gmail won't take no for an answer," writes Dan Goodin. "It keeps asking me if I want to use Google's Gemini AI tool to summarize emails or draft responses. As the disclaimer at the bottom of the Gemini tool indicates, I can't count on the output being factual, so no, I definitely don't want it."

Windows: While many complaints about Windows 11 originated with Windows 10, the newer version continues the trend of unwanted features, forced updates, and telemetry data collection. Bugs and performance issues also plague the operating system. "... it sure is easy to resent Windows 11 these days, between the well-documented annoyances, the constant drumbeat of AI stuff (some of it gated to pricey new PCs), and a batch of weird bugs that mostly seem to be related to the under-the-hood overhauls in October's Windows 11 24H2 update," writes Andrew Cunningham. "That list includes broken updates for some users, inoperable scanners, and a few unplayable games. With every release, the list of things you need to do to get rid of and turn off the most annoying stuff gets a little longer."

Web Discourse: The rapid spread of memes, trends, and corporate jargon on social media has led to a homogenization of online communication, making it difficult to distinguish original content and creating a sense of constant noise. "[T]he enshittifcation of social media, particularly due to its speed and virality, has led to millions vying for their moment in the sun, and all I see is a constant glare that makes everything look indistinguishable," writes Jacob May. "No wonder some companies think AI is the future."

Indonesia Plans Minimum Age For Social Media Use 19

Indonesia plans to issue a regulation to set a minimum age for users of social media, a move aimed at protecting children, its communications minister has said. From a report: The plans follows Australia's decision to ban children under 16 from accessing social media, with fines for tech giants from Instagram and Facebook owner Meta to TikTok if they failed to prevent children accessing their platforms. Minister Meutya Hafid did not say what the minimum age would be in Indonesia. Her remarks, made late on Jan 13, came after she discussed the plan with President Prabowo Subianto.

Australian Open Avatars Helping Tennis Reach New Audience 25

The Australian Open has introduced a project called AO Animated -- "near-live, commentated coverage of the Australian Open, free to anyone across the world via YouTube, enhanced via a stream of comments from a like-minded online community," reports The Guardian. Blending real-world data with virtual avatars, the animated coverage has garnered significant viewer interest, especially among gamers and tech enthusiasts. From the report: [I]t's no surprise a project called AO Animated has taken off at this year's grand slam tournament at Melbourne Park. The catch? The players, ball and court are all computer-generated. That hasn't dissuaded hundreds of thousands of viewers from tuning into this vision of the Australian Open, featuring video game-like avatars but using real-world data in an emerging category of sports broadcasting helping tennis reach new fans.

The loophole allows the Australian Open to show a version of live events at the tournament on its own channels, despite having sold lucrative exclusive broadcast rights to partners across the globe. The technology made its debut at the grand slam last year and audiences peaked for the men's final, the recording of which has attracted almost 800,000 views on YouTube. Interest appears to be trending up this year and the matches are attracting roughly four times as many viewers than the equivalent time in 2024.

The director of innovation at Tennis Australia, Machar Reid, said although the technology was far from polished it was developing quickly. "Limb tracking is complex, you've got 12 cameras trying to process the silhouette of the human in real time, and stitch that together across 29 points in the skeleton," he said. "It's not as seamless as it could be -- we don't have fingers -- but in time you can begin to imagine a world where that comes." The data from sensors on the court is ingested and fed into a system that can produce the graphic reproduction with a two-minute delay. The same commentary and arena noises that would otherwise be heard on the television -- as well as interstitial vision direct from the broadcast -- are synced with the virtual representation of the match.

TikTok, Facing a US Ban, Is Also Waging Legal Battles Around the World (msn.com) 38

An anonymous reader shared this report from the New York Times: Russia fined TikTok for not removing prohibited content. The results of a presidential election in Romania were thrown out over concerns the app had been used to spread foreign influence. Albania banned TikTok for a year following the stabbing death of a teenager by another one after the two quarreled online... That was all in just the last month...

TikTok has confronted legal and political scrutiny around the world in recent years, facing outright or partial bans in at least 20 countries, as governments have grown alarmed by its ties to China and its wide influence, especially among young people... [A]s TikTok's algorithm captured attention spans around the world, it alarmed lawmakers, who say TikTok has quickly turned from a domain of cat videos and dance trends into a potentially disruptive social, political and economic force. Officials from Montana to New Zealand have warned that TikTok could be used to incite violence, spread false information and worsen mental health. Lawmakers also worry TikTok could share user data like location and browsing history with the Chinese government. Young people need to be protected from "the frightening pitfalls of the algorithm," [Albania prime minister Edi] Rama said.

TikTok lost its largest audience (India) "after India's simmering geopolitical conflict with China boiled over into hand-to-hand combat along their shared border" — resulting in a total ban in the world's single most-populous country. And the article notes TikTok is also blocked on government devices in Taiwan, Britain, Australia, France, and Canada, "as well as the executive arm of the European Union and New Zealand's Parliament..."

But "Despite the mounting scrutiny, TikTok remains incredibly popular worldwide. More than a billion people use the app every month."

Could a Sponge Made from Squid Bones Help Remove Microplastics? (cnn.com) 27

While microplastics seem to be everywhere, CNN reports that scientists in China "have come up with a possible solution: a biodegradable sponge made of squid bones and cotton" (which contain two organic compounds "known for eliminating pollution from wastewater...") They then tested the sponge in four different water samples, taken from irrigation water, pond water, lake water and sea water, and found it removed up to 99.9% of microplastics, according to a study published last month in Science Advances... The sponge created by the Wuhan researchers was able to absorb microplastics both by physically intercepting them and through electromagnetic attraction, the study said.

Previously studied methods for absorbing plastics tend to be expensive and difficult to make, limiting their scalability. Last year, researchers in Qingdao, China developed a synthetic sponge made of starch and gelatin designed to remove microplastics from water, though its efficacy varied depending on water conditions. The low cost and wide availability of both cotton and squid bones mean [the Chinese researchers' sponge] "has great potential to be used in the extraction of microplastic from complex water bodies," according to the study.

Shima Ziajahromi, a lecturer at Australia's Griffith University who studies microplastics, called the squid-cotton-sponge method "promising" and said it could be an effective way to "clean up the high risk and vulnerable aquatic ecosystem." However, the study's authors did not address whether the sponge can remove microplastics that sink to the sediment, which is the majority of microplastics in our waters, said Ziajahromi, who was not involved in the study. Another "critical issue" is the proper disposal of the sponges, Ziajahromi said. "Although the material is biodegradable, the microplastics it absorbs need to be disposed of properly," she said. "Without careful management, this process risks transferring microplastics from one ecosystem to another."

Ultimately, Ziajahromi added, minimizing plastic pollution is in the first place should remain a "top priority."

Microsoft Is Forcing Its AI Assistant on People - And Making Them Pay (msn.com) 101

Microsoft has integrated its AI assistant Copilot into Microsoft 365 subscriptions in Australia and Southeast Asia, simultaneously raising prices for all users. The move forces customers to pay for AI features regardless of interest, prompting complaints about intrusive pop-ups and price hikes, WSJ reports. From the report: Some users said on social media that Copilot pop-ups reminded them of Clippy, Microsoft's widely derided Office helper from the late 1990s, that would frequently offer unsolicited help.

[...] The change demonstrates the lengths to which Microsoft is going to try to profit from its huge investments in AI. Copilot, which is built with technology from OpenAI, is a key part of Chief Executive Satya Nadella's plan to keep expanding Microsoft's software business for consumer and corporate customers.

Australia Moves To Drop Some Cryptography By 2030 (theregister.com) 31

An anonymous reader shares a report: Australia's chief cyber security agency has decided local orgs should stop using the tech that forms the current cryptographic foundation of the internet by the year 2030 -- years before other nations plan to do so -- over fears that advances in quantum computing could render it insecure.

The Land Down Under's plans emerged last week when the Australian Signals Directorate (ASD) published guidance for High Assurance Cryptographic Equipment (HACE) -- devices that send and/or receive sensitive information -- that calls for disallowing the cryptographic algorithms SHA-256, RSA, ECDSA and ECDH, among others, by the end of this decade.

Bill Buchanan, professor in the School of Computing at Edinburgh Napier University, wrote a blog post in which he expressed shock that the ASD aims to move so quickly. "Basically, these four methods are used for virtually every web connection that we create, and where ECDH is used for the key exchange, ECDSA or RSA is used to authenticate the remote server, and SHA-256 is used for the integrity of the data sent," he wrote. "The removal of SHA-256 definitely goes against current recommendations."

Music Sector Workers Will Lose Nearly a Quarter of Their Income to AI in 4 Years, Study Suggests (theguardian.com) 204

The Guardian reports: People working in the music sector will lose almost a quarter of their income to artificial intelligence within the next four years, according to the first global economic study examining the impact of the emerging technology on human creativity. Those working in the audiovisual sector will also see their income shrink by more than 20% as the market for generative AI grows from €3bn (A$4.9bn) annually to a predicted €64bn by 2028.

The findings were released in Paris on Wednesday by the International Confederation of Societies of Authors and Composers (CISAC), representing more than 5 million creators worldwide. The report concluded that while the AI boom will substantially enrich giant tech companies, creators' rights and income streams will be drastically reduced unless policymakers step in...

The study concluded that under current regulatory frameworks in most countries, creators stand to lose on two fronts. Unauthorised use of their works by generative AI models will eat into remuneration earned through copyright, while at the same time work opportunities will shrink as AI-generated outputs become more competitive against human-made works. The report predicted that by 2028, exponential growth in generative AI music would account for about 20% of traditional music streaming platforms' revenues, and about 60% of music libraries' revenues.

The report warned of revenue "derived directly from the unlicensed reproduction of creators' works, representing a transfer of economic value from creators to AI companies," according to the article.

On a hopeful note, it adds that the CISAC's president also applauded Australia and New Zealand for their thoughtful response to the issue. "By setting a gold standard in AI policy, one that protects creators' rights while fostering responsible and innovative technological development, Australia and New Zealand can ensure that AI serves as a tool to enhance human creativity rather than replace it."

Australia Struggling With Oversupply of Solar Power (abc.net.au) 203

Mirnotoriety writes: Amid the growing warmth and increasingly volatile weather of an approaching summer, Australia passed a remarkable milestone this week. The number of homes and businesses with a solar installation clicked past 4 million -- barely 20 years since there was practically none anywhere in the country. It is a love affair that shows few signs of stopping.

And it's a technology that is having ever greater effects, not just on the bills of its household users but on the very energy system itself. At no time of the year is that effect more obvious than spring, when solar output soars as the days grow longer and sunnier but demand remains subdued as mild temperatures mean people leave their air conditioners switched off.

Such has been the extraordinary production of solar in Australia this spring, the entire state of South Australia has -- at various times -- met all of its electricity needs from the technology.

[...] [T]here is, at times, too much solar power in Australia's electricity systems to handle.

Utilities Are Trying Enormous 'Flow' Batteries Big Enough to Oust Coal Power Plants (yahoo.com) 143

To help replace power plants, Japan's northernmost island, Hokkaido, "is turning to a new generation of batteries designed to stockpile massive amounts of energy," reports the Washington Post.

"The Hokkaido Electric Power Network (HEPCO Network) is deploying flow batteries, an emerging kind of battery that stores energy in hulking tanks of metallic liquid." [F]low batteries are making their debut in big real-world projects. Sumitomo Electric, the company that built the Hokkaido plant, has also built flow batteries in Taiwan, Belgium, Australia, Morocco and California. Hokkaido's flow battery farm was the biggest in the world when it opened in April 2022 — a record that lasted just a month before China built one that is eight times bigger and can deliver as much energy as an average U.S. natural gas plant. "It looks like flow batteries are finally about to take off with interest from China," said Michael Taylor, an energy analyst at the International Renewable Energy Agency, an international group that studies and promotes green energy. "When China starts to get comfortable with a technology and sees it working, then they will very quickly scale their manufacturing base if they think they can drive down the costs, which they usually can...."

Lithium-ion batteries are perfect for smartphones because they're lightweight and fit in small spaces, even if they don't last long and have to be replaced frequently. Utilities have a different set of priorities: They need to store millions of times more energy, and they have much more room to work with. "If you think about utility-scale stationary applications, maybe you don't need lithium-ion batteries. You can use another one that is cheaper and can provide the services that you want like, for example, vanadium flow batteries," said Francisco Boshell, a researcher at the International Renewable Energy Agency...

Flow batteries are designed to tap giant tanks that can store a lot of energy for a long time. To boost their storage capacity, all you have to do is build a bigger tank and add more vanadium. That's a big advantage: By contrast, there's no easy way to adjust the storage capacity of a lithium-ion battery — if you want more storage, you have to build a whole new battery... One major barrier to building more of these battery farms is finding enough vanadium. Three-quarters of the world's supply comes as a by-product from 10 steel mills in China and Russia, according to Kara Rodby [a battery analyst at the investment firm Volta Energy Technologies] who got her PhD at the Massachusetts Institute of Technology studying the design and market for flow batteries. Australia, South Africa and the United States also produce vanadium, but in much smaller quantities. Mines that have been proposed could boost supply. And some flow battery start-ups are trying to sidestep the vanadium problem entirely by using different materials that are easier to buy.

The other hurdle is their up-front cost. Vanadium flow batteries are at least twice as expensive to build as lithium-ion batteries, Rodby said, and banks are hesitant to lend money to fund an unfamiliar technology. But experts say flow batteries can be cheaper in the long run because they're easier to maintain and last longer. A lithium-ion battery might have to be replaced after 10 years, but Rodby says flow batteries can last much longer. "There really is no finite lifetime for a flow battery in the way there is for lithium-ion," Rodby said.

Here's an interesting statistic from the article. "Over the next six years, utilities will have to build 35 times as many batteries as there are today to soak up all extra renewable energy that will come online, according to the International Energy Agency."
