Scientists develop extremely thin material that could usher in next-gen fuel source: 'Taking into account the global challenges'

Yahoo2 days ago
Norwegian experts are making an already thin component for hydrogen fuel cells even slimmer to reduce the cost of the cleaner energy source, according to a news release on the breakthrough.
The research is happening at SINTEF, an independent institute in Norway.
Fuel cells work sort of like a battery, with similar parts. They convert hydrogen's chemical energy into electricity, water, and heat, according to the U.S. Department of Energy.
As part of its criticism of the fuel, Sierra Club has noted that using hydrogen in a cell instead of burning it to produce energy eliminates harmful fume pollution. Cleaner hydrogen made through renewably powered electrolysis is also more planet-friendly than the standard production process that uses fossil fuels.
However, fuel cells are expensive to produce, in large part because of costly components that include platinum. The Norwegian team addressed the issue with smaller parts, per the release.
"By reducing the amount of platinum in the fuel cell, we're not only helping to reduce costs, we're also taking into account the global challenges regarding the supply of important raw materials and sustainability," researcher Patrick Fortin said in the release.
The membrane and catalyst account for 41% of a fuel cell's cost, which is why the team focused on them. The membrane being studied is made of a polymer that is considered a PFAS, or forever chemical, that can have a lasting, negative impact on people and the environment. The researchers cut membrane thickness by 33% — making a sheet of paper seem like cardboard by comparison — reducing pollution as well as 20% of the costs, per the release.
On the platinum front, the team figured out a better way to arrange the costly metal's particles to produce the most energy with the least amount of material. Platinum particles are like microscopic reactors "that [convert] hydrogen into electricity," the experts added. They were able to cut platinum content by more than 62% with some rearranging.
Fuel cells are already powering superyachts, larger ships, and even helicopters. Researchers elsewhere are also working to make the tech more accessible.
If fuel cells can replace combustion engines across multiple sectors, it could greatly help to clear the air. Transportation accounts for nearly 30% of U.S. planet-warming fume output, and tailpipe exhaust increases the risk of cancer and other health problems, per the Environmental Protection Agency.
Should the U.S. invest more in battery innovations?

Battery-powered electric vehicles are a great, reliable switch already available. Better yet, tax breaks remain to offset up to $7,500 of the cost. You can also plan to save around $1,500 annually in gas and maintenance expenses. Even driving more efficiently, by eliminating idling, can cut pollution and save you cash.
In Norway, the experts think their invention can soon have a big impact for scaling fuel cells.
"If the innovations are put into practice, our research will contribute to making future clean energy technologies — like powerful … fuel cells — cheaper and more sustainable," Fortin said in the release.

How the Trump tax bill could help China win at A.I.

Republicans in Congress produced a surprise winner this week when they axed hundreds of billions of dollars in federal clean-energy subsidies: China's artificial intelligence industry. China is pouring money into energy production to support its bid to dominate AI. America's tech industry, meanwhile, has been scrounging for more energy to run power-hungry AI data centers and strongly urged Congress not to wipe out solar and wind tax credits. Subscribe to The Post Most newsletter for the most important and interesting stories from The Washington Post. Solar panels and windmills are the fastest-growing sources of power in the United States, accounting for 80 percent of new energy being added to the grid. Yet Republican lawmakers and Trump administration officials remain intent on stifling clean energy progress in America, calling it Biden-era folly. Now the consequences of the massive cuts in the GOP tax and budget bill are coming into focus. Modeling of the package by energy economists shows they will substantially reduce the amount of electricity added to the U.S. power grid in the coming years, even as China races ahead. Wind and solar power 'is critical in the near term,' said Ben King, director of the U.S. energy program at the Rhodium Group, a research firm that has developed projections of the bill's impact. 'This creates a risk that energy projects just won't get built. At the same time, China is adding staggering electricity capacity.' The wind and solar electricity that China added to its power grid in just the first five months of this year is more than quadruple all the new electricity the U.S. added to its grid from all sources in 2024. China is simultaneously rapidly expanding its fleet of fossil fuel and nuclear plants. The Trump administration plans to accelerate new electricity generation from natural gas and nuclear power, but those efforts will take years, experts warn. There are no major new nuclear plants under construction, and they can take a decade or more to build. A global backlog of gas turbines means it can take five years just to build a single gas-powered plant. 'We need a huge amount of electricity after 20 years in which we did not have to deal with rising demand,' said Jason Bordoff, director of the Center on Global Energy Policy at Columbia University. 'Other countries are moving fast and being quite innovative. If we are not adding new power to the grid, companies are going to have to get it from other places.' According to the think tank Energy Innovation, the cuts in the Senate's version of the bill, which survived the House vote intact Thursday, would reduce the amount of new electricity the U.S. is able to bring online over the next decade by 344 gigawatts - enough to power nearly half the homes in the country. The loss of such generation would create an immense challenge for not just AI companies, but other industries needing to power factories as well as residential customers struggling with rising utility costs. The models are built on the premise that the loss of tax credits will boost development costs, which would require solar and wind operators to force up rates, rattling investors and risking the viability of projects. The 344 gigawatts in new power that Energy Innovation estimates would be lost is based on an assumption that solar and wind development drops 50 percent by 2035. The Trump administration waves away such warnings as overblown. The president says the tax credits that have propelled the growth of renewable energy in the U.S. are a 'scam,' arguing that wind and solar installations are a blight on the landscape. The administration contends intermittent energy produced by wind and solar, despite advances in battery technology, don't meet the needs of industry, especially the enormous, 24/7 demands of AI data centers. Energy Secretary Chris Wright calls renewable energy a 'parasite' on the power grid, undermining its stability and consuming transmission-line capacity that could be delivering more stable gas or nuclear energy. "Winning the AI race will require a significantly larger supply of around-the-clock, reliable, and uninterrupted power – unfortunately, this was not a priority of the last administration,' he said in a statement Wednesday night. Tech firms and their industry groups say eliminating the tax incentives for clean power hamstrings their ability to compete with Chinese AI development. They also say it could lead to soaring electricity prices in the United States. Both the Data Center Coalition and the Clean Energy Buyers Association, industry groups led by tech firms, warned lawmakers that the imperiled tax credits are needed for domestic AI growth. The key tax credits for large wind and solar installations will be phased out for projects not under construction by the end of June 2026 under the bill, which Trump hoped to sign Friday following expected House passage. The Biden-era incentives would have extended into the 2030s. There are thousands of eligible projects that have been announced but not yet started, amounting to a half-trillion dollars in planned investment, according to Energy Innovation. Now the question is how many of those projects can start construction before the deadline. Depending on how many projects can get shovels in the ground quickly, said Aaron Zubaty, chief executive of Eolian, a large clean energy developer, 'the U.S. has a fighting chance to keep major data center developments domestic and not lose them to the Middle East.' But, he said, China's advantage is nonetheless cemented by the budget bill. 'I've had multiple people I work with in Europe say to me that it is pretty clear who is going to be the dominant superpower in a decade, and that it will not be the U.S.,' he said. 'Dominance now depends on who has the most electricity. And by only building new gas, coal, and nuclear power plants you are not going to be able to grow U.S. supply quickly enough.' Industry officials say countries like Saudi Arabia, Qatar and the United Arab Emirates are aggressively courting American AI projects, offering plentiful, cheap power from renewables and gas. But locating major U.S. AI infrastructure in a region where alliances are constantly shifting and enemy combatants are an arm's length away 'is not good for America's national security interests or its economy,' Bordoff said. To keep up with the demands of AI and other industries, federal regulators say the United States needs to add to its grid by 2035 the amount of power used by all of California, Texas and New York combined. Many companies are feeling burned by the abrupt reversal of clean energy incentives, said Jason Grumet, chief executive of the American Clean Power Association, which represents several large companies heavily invested in both gas and renewables. As the Trump administration encourages investment in gas plants, companies are left to wonder if the federal support will still be there after a new president is in office. 'Every part of the energy economy is worried that they will make investments that in four years will be disfavored by the next administration,' Grumet said. 'We need durable energy policy.'

Psychologists now know exactly what makes someone cool. Turns out, the definitions are universal 3% mortgage rates aren't dead—housing market sees 127% increase in buyers taking over old loans There's a reason your Sam's Club rotisserie chicken looks different Tally is the best free tool for creating surveys. They're better-looking and more flexible than Google Forms, and they're just as easy to create in 60 seconds. Use it for any kind of survey, whether you're getting feedback from clients or students, collecting RSVPs, or gathering ideas. Get Started: Pick a template or a blank page. Add questions: multiple choice, open text, ranking, or many others. You can ask respondents to upload a file or make a payment. To enhance your design, add text blocks, images, or videos between questions. Free. 99% of the features are available without paying. I haven't upgraded because the free offering is so complete. . Based in Belgium, the company complies with Europe's strict GDPR rules. Its software respects people's privacy. Easy. No complicated menus or settings. As this 30-second video demo illustrates, you can just start typing on a blank page and press ' / ' to add a question from a list of options. For non-techies it's easier than Typeform, Survey Monkey or Qualtrics. Flexible. Works for any kind of form, quiz or survey. Tally is superb for feedback, market research, even selling something, as in these templates: Flexible design. Incorporate video, images or descriptions to create the feel of a readable page that's less bureaucratic than traditional forms. Add a cover image and logo. The forms look great, like Notion pages. They're less generically corporate than Microsoft Forms or Google Forms. Easily shareable. Email your survey, share a link to it—as I did above—or embed it within a site. Connect Tally to other tools. Check a box to easily share whatever data your form collects to Google Sheets, Notion, Slack, or Airtable. These simple integrations help you analyze responses easily. Shortcut: type ' in your browser bar to start a new form, if you're logged in. Aim for 5 to 8 questions. That's the survey sweet spot requiring just 5 to 10 minutes of a respondent's time. Learn from other good surveys. Check examples of others using Tally, a pack of survey templates for growth, and lessons from newsletter surveys cited by Dan Oshinsky's excellent Inbox Collective. Incorporate , sending people to a question based on a prior answer. I tested that in my new Wonder Tools feedback survey above. That ensures people only see questions relevant to them. Use to categorize or summarize text replies. AI can help spot patterns. That's useful when you have hundreds of responses to analyze.

For charts or detailed visuals, you'll need a different tool. No AI summaries or adaptation. Google Forms can now summarize responses for you with AI assistance. Tally doesn't yet have that capability. New tools like Parliant and BetterFeedback can even adapt questions based on prior responses. Typeform AI helps word questions for you. No mid-range subscription. You can use most Tally features for free, but the pro price of $29/monthly is a big jump for premium features. These include customized confirmation emails, custom domains, and unlimited team collaboration. You can also accept large file uploads (over 10mb) and remove Tally branding. I'm fine with the free plan, which includes unlimited forms and question types. Tally has published its own comparisons with other tools. But here's my take on other good survey tools to consider the next time you're making a form. Free & Fast: works with your existing Google account. It's functional for registration forms or simple feedback surveys, but its features and design have stagnated over the past decade. Elegant and Professional: presents questions one by one, making it less overwhelming for survey respondents than traditional survey tools. It remains superb for multiple reasons. It's expensive, though, and the advanced features are complex. Flexible and Easy: now lets you embed surveys export data to multiple places. They're more flexible than Survey Monkey or Microsoft Forms, which have the stiff design feel of enterprise tools made for mass-market feedback. Premium for Businesses: is another premium alternative for businesses. You can customize fonts and colors, and integrate a form into your CRM or any database. Or trying make an AI agent. For DIY flexibility: works well both for forms and documents. That helps you organize survey responses within existing docs. For team : , like Coda, lets you create forms with responses that flow directly into tables. That helps you sort, filter, analyze and share results efficiently. For preference ranking: is another specialized survey tool I've used and recommend for stack rankings—assessing customer preferences. Ask people to compare a series of paired options to help set priorities. Live polling: is what I prefer for quick live polling during events.

Night Sky: How noctilucent clouds are made and Wales' space progress

This week saw a wonderful display of noctilucent clouds across the region as last Sunday evening's skies took on a dramatic and eerie appearance. Nick Edwards managed to capture the event over Newport, as the sun's rays reaching out from far below the horizon lit up tiny frozen water droplets high up in the Earth's atmosphere, creating the shimmering effect of wispy white clouds tinged with blue. Taken from the Latin for 'night-shining', we can expect further activity throughout the summer. We have a full moon on Thursday, July 10. This particular full moon is often referred to as a 'Buck Moon' because of the emergence of antlers on a deer buck's forehead during this part of the season. In Celtic folklore, terms such as 'Mead' or 'Herb' Moon can be found, with the Anglo-Saxons referring to it as a 'Hay Moon.' Space news and the proposed cuts to NASA's budget by the Trump administration will more than likely impact Europe's ExoMars rover mission which is already behind schedule. With the aim of placing a rover to explore the surface of Mars, it would seem the European Space Agency, (ESA), may have to go it alone. Recently, the Snowdonia Space Centre opened its Space Test and Training Centre, (STTC), with a day of demonstrations including rocket launches and the upward despatching of a high-altitude balloon. In a move to stay competitive with the rest of the UK and indeed Europe, the day signified Wales' intent to be at the forefront of enabling those interested in having their high-tech payloads delivered into space via rockets. It's a bold and innovative concept which is slowly gathering momentum but for those who lived during a Wales that was sustained by the coal industry and in more recent times the steel industry, a stark reminder that the shift in economic focus now lies firmly with the likes of such technology as 'microgravity manufacturing.' Attended by Rebecca Evans, MS, Welsh Government cabinet secretary for economy, energy, and planning, the new centre has received £820,000 of funding from the UK Space Agency with Matt Archer, its launch director, also in attendance. All told, with other financial contributions, £1.3 million has been invested with a view to boost the local economy and employment opportunities. With six other such Spaceports at sites including Argyll in western Scotland and Newquay in Cornwall, there has to be an exercise in caution following the announcement last week that the SaxaVord Spaceport in Lamba Ness, Shetlands Islands, (which appears to be further down the operational line than others), has delayed its first satellite launch from 2025 to 2026. Finally this week, the Earth's rotation during July and August is set to speed up with Wednesday, July 9, expected to be 1.30 milliseconds shorter than the usual length of a day. The speeding up over the two months is down to several factors, including sea levels, bucking the trend that overall rotation of the Earth is slowly down.
