Reinventing industry: Carbon capture technologies lead the charge against climate change

Researchers are testing a new method of capturing CO2 from energy-intensive industries and converting it into valuable chemicals and fuels.
In a potential game-changer for heavy industry, a magnesium-oxide mine in Greece received seven special containers in November 2024 with equipment designed to capture CO₂ and transform it into a valuable chemical, right there on site.
Long blamed for driving up the planet’s temperature, CO2 could now be converted into jet fuel for passenger aircraft—cutting emissions from both mining and transport.
“We just started capturing CO2, which is an amazing milestone,” said Dr. Haris Yiannoulakis, research and development manager at Grecian Magnesite, the producer of magnesium oxide.
The containers came from the Petrobrazi oil refinery in Romania. There, the carbon capture technology had been tried out as part of a project called ConsenCUS, involving seven countries and three test sites.
Getting down
The EU has set its sights on slashing greenhouse gas emissions by 55% by 2030, compared to 1990 levels. The ultimate goal: climate neutrality for industry by 2050.
ConsenCUS brings together new technologies to trap CO₂ from three notoriously hard-to-abate industries: oil refining, mining and cement production. These sectors face a double challenge, as CO₂ is generated both from burning fossil fuels and from the raw materials themselves.
For example, at the Grecian Magnesite mine site, raw material magnesite—a natural mineral found in rocks—is mined and heated up to 2,000°C to yield magnesium oxide. This material is crucial to a wide range of European industries, from steel and glass to fertilizers, animal feed and pharmaceuticals.
The downside, however, is that the thermal treatment releases CO2 both from the decomposition of magnesite and the fuel required for the process.
Three steps
The pilot plant in Greece is now tackling CO₂ conversion in three steps, explains Sara Vallejo Castaño, a chemical engineer at Wetsus research institute in the Netherlands.
First, a capture column separates CO₂ from factory gases, mixing it with water and potassium hydroxide. The CO₂ dissolves and reacts, forming potassium carbonate, which locks the gas in liquid form.
The second step uses electricity to raise the acidity of the solution, which releases CO2.
This method is simpler and greener than traditional heating or hazardous chemicals because it uses only electricity and water as resources.
A third step turns the CO2 into formic acid (or formate), a simple, naturally occurring chemical that can be found in nettles and ant bites.
“Formic acid is a well-known molecule used in the chemical sector,” said Dirk Koppert, the coordinator of ConsenCUS at New Energy Coalition, a nonprofit organization in the Netherlands.
One Dutch company, Coval Energy, already produces formic acid in this way from CO2. The acid is then fed to microbes to make fats and proteins. The proteins could be ingredients in cattle and fish feed, while the fatty acids could one day be used as a replacement for jet fuel.
Tough cement
The first testing site for the new technology was at Aalborg Portland in northern Denmark. This is one of the largest cement manufacturers in Europe, producing up to 1.8 million tons of gray cement and 0.8 million tons of white cement annually and operating since 1889.
Sustainability is a major selling point for its cement. The factory now uses non-fossil fuels for more than 30% of its heating needs for gray cement production, for example.
“We are reducing our dependence on fossil fuels and reducing CO2 emissions,” said Jesper Damfoft, sustainability director at the company.
But the manufacturing of cement still releases CO2 in the process.
The main cement ingredients in Aalborg are sand, dredged from the Limfjord waterway, and chalk from a local quarry. This calcium-rich chalk is heated to temperatures of about 1,500°C to produce lime (calcium oxide), which is essential for manufacturing cement.
When heated, the chalk’s carbon and oxygen atoms combine to form CO₂ gas, making cement production a major source of global emissions—by some estimates, accounting for 7%–8% of the world’s total.
A way forward is to capture and store CO2 underground, or put it to other uses, such as by making formic acid.
Under the EU’s emissions trading scheme, the price per excess ton of CO2 that companies have to pay stood at around €73 in June 2025, but it is expected to rise.
“Carbon prices are relatively low, but are predicted to be €150 per ton in 2030, and who knows what they will be beyond that,” said Yiannoulakis. Clearly, European industries must prepare.
The new capture technology remained in Greece until June for testing. The hope is to move the technology closer to a commercial plant and put it to work to capture CO2.
Working out the technicalities of how to capture CO2 gas and produce a desirable chemical required a dozen industry and research partners to come together, including those from universities in Canada and China.
“Without EU funds, we would not be able to build this project and test these technologies,” said Koppert.
Bringing communities on board
However, technical expertise is only part of the story.
Jacob Nielsenat from Robert Gordon University in Scotland has been investigating how to give citizens a voice in these new technologies.
He quickly realized that “lots of people didn’t know what carbon capture is, so we were asking people to give us their opinion on something they didn’t know anything about.”
Along with his colleague Kostas Stavrianakis, he invented a card game to prompt discussions on carbon capture. Both believe that results will come. “Most citizens are perfectly able to understand the complexities around these technologies,” said Stavrianakis.
He emphasized that the industry needs to talk to local people. “If you want a project to go ahead, it is always better to involve communities so they can feel part of it.”

Want to Start a Website? These Are the Best Website Builders

Top Website Builders
Publishing a website is still more complicated than it has any right to be, but the best website builders streamline the process. Instead of juggling a bunch of files on a server and learning the ins and outs of networking, website builders do exactly what’s written on the tin. Piece by piece, using a drag-and-drop interface, you can design your website the way you want with immediate feedback, rather than spending time buried in code and hoping it comes out on the other end.
There are dozens of website builders, and most of them range from decent to straight-up bad. Any web host with a bit of ambition has a website builder floating around, even if it’s slow, clunky, and lacking features. I focused on finding the best tools for building your website that go beyond just an add-on, and these are my favorites. If you’re after something simpler than a full-blown website, check out our list of the Best Portfolio Websites.

Best Website Builder for Most
You’ve heard of Squarespace over and over again, I’m sure, and that’s not an accident. It’s an inviting website builder that made a name for itself with bold, striking templates. Beneath the veneer of attractive, but seemingly simple, websites, you’ll find one of the most capable website builders on the market. That balance of power and usability is what sets Squarespace apart.
It feels like a creative tool. Where other website builders lag and stutter to get a new element on your page, Squarespace feels fluid. Your dashboard gives you quick access to edit your site, and around every corner, Squarespace feels designed so you never have to look up a tutorial. I started a simple photography website, and within an hour, I had a custom course page set up, an appointment schedule with automated confirmation emails, and services (with pricing and the ability to accept payments) configured.
Squarespace isn’t cheap, but it also doesn’t meddle in restrictive, low-cost plans. Even on the Basic plan, you have access to ecommerce tools and space for multiple contributors.

Best Cheap Website Builder
Hostinger is better known as a web hosting provider, but it has a surprisingly robust website builder that you can use on its own or for free as part of a hosting package. You don’t get the same world-class template design and dense feature-set of a more expensive builder like Squarespace, but that’s OK. Hostinger’s website builder will run you just a few bucks a month, and based on my testing, it feels heavily angled toward newcomers.
You sacrifice some power for convenience, but there’s an awful lot you can accomplish with Hostinger. Integrations with PayPal, Stripe, and Square allow you to quickly set up e-commerce. Add-ons with WhatsApp give you live chat capabilities, and Printful support means you can sell print-on-demand merchandise. And, if you outgrow the website builder, Hostinger allows you to export your website’s content to WordPress.
Where Hostinger wins for me is through its AI tools. Just about every website builder these days has AI integrated in some way, but it’s around every corner at Hostinger. You need to pay extra for some of these AI features—the logo generator, for example, requires credits—but they give you a great starting point for mocking up the look, feel, and tone of your website.
Hostinger Pricing and Plans
Best for Small Businesses
Wix is undoubtedly the biggest competitor to Squarespace, and I had a hard time putting one above the other. Ultimately, Wix ended up in the backseat due to higher prices and a slightly less intuitive interface. That’s partly because of how powerful Wix is. Rather than corral you in an elegant (if restrictive) website-building workflow, Wix gives you a ton of options.
First, templates. You get a few hundred elsewhere, but Wix offers over 2,000 templates. At the time of writing, there are 223 pages of them on Wix’s website. They aren’t all winners, but I was able to mock up a quick photography portfolio website within a few minutes by browsing the templates and uploading a few photos.

A New Algorithm Makes It Faster to Find the Shortest Paths

The original version of this story appeared in Quanta Magazine.
If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost. You may end up spending too much time putting the pieces in order.
This dilemma is especially relevant to one of the most iconic problems in computer science: finding the shortest path from a specific starting point in a network to every other point. It’s like a souped-up version of a problem you need to solve each time you move: learning the best route from your new home to work, the gym, and the supermarket.
“Shortest paths is a beautiful problem that anyone in the world can relate to,” said Mikkel Thorup, a computer scientist at the University of Copenhagen.
Intuitively, it should be easiest to find the shortest path to nearby destinations. So if you want to design the fastest possible algorithm for the shortest-paths problem, it seems reasonable to start by finding the closest point, then the next-closest, and so on. But to do that, you need to repeatedly figure out which point is closest. You’ll sort the points by distance as you go. There’s a fundamental speed limit for any algorithm that follows this approach: You can’t go any faster than the time it takes to sort.
Forty years ago, researchers designing shortest-paths algorithms ran up against this “sorting barrier.” Now, a team of researchers has devised a new algorithm that breaks it. It doesn’t sort, and it runs faster than any algorithm that does.
“The authors were audacious in thinking they could break this barrier,” said Robert Tarjan, a computer scientist at Princeton University. “It’s an amazing result.”
The Frontier of Knowledge
To analyze the shortest-paths problem mathematically, researchers use the language of graphs—networks of points, or nodes, connected by lines. Each link between nodes is labeled with a number called its weight, which can represent the length of that segment or the time needed to traverse it. There are usually many routes between any two nodes, and the shortest is the one whose weights add up to the smallest number. Given a graph and a specific “source” node, an algorithm’s goal is to find the shortest path to every other node.
The most famous shortest-paths algorithm, devised by the pioneering computer scientist Edsger Dijkstra in 1956, starts at the source and works outward step by step. It’s an effective approach, because knowing the shortest path to nearby nodes can help you find the shortest paths to more distant ones. But because the end result is a sorted list of shortest paths, the sorting barrier sets a fundamental limit on how fast the algorithm can run.

Australian airline Qantas says millions of customers’ data leaked online

Australian airline Qantas said Sunday that data from 5.7 million customers stolen in a major cyberattack this year had been shared online, part of a leak affecting dozens of firms.
Disney, Google, IKEA, Toyota, McDonald’s and fellow airlines Air France and KLM are also reported to have had data stolen in a cyberattack targeting software firm Salesforce, with the information now being held to ransom.
Salesforce said this month it was “aware of recent extortion attempts by threat actors.”
Qantas confirmed in July that hackers had targeted one of its customer contact centers, breaching a computer system used by a third party now known to have been Salesforce.
They secured access to sensitive information such as customer names, email addresses, phone numbers and birthdays, the blue-chip Australian company said.
No further breaches have taken place since and the company is cooperating with Australian security services.
“Qantas is one of a number of companies globally that has had data released by cyber criminals following the airline’s cyber incident in early July, where customer data was stolen via a third party platform,” the company said in a statement.
Most of the data leaked was names, email addresses and frequent flyer details, the firm said.
But some of the data included customers’ “business or home address, date of birth, phone number, gender and meal preferences.”
“No credit card details, personal financial information or passport details were impacted,” Qantas said.
It also said it had obtained a legal injunction with the Supreme Court of New South Wales, where the firm is headquartered, to prevent the stolen data being “accessed, viewed, released, used, transmitted or published.”
Cybersecurity expert Troy Hunt told AFP that would do little to prevent the spread of the data.
“It’s frankly ridiculous,” he said.
“It obviously doesn’t stop criminals at all anywhere, and it also really doesn’t have any effect on people outside of Australia.”
Hackers ‘laying siege’
In response to questions about the leak, tech giant Google pointed AFP to an August statement in which it said one of its corporate Salesforce servers had been targeted. It did not confirm if the data had been leaked.
“Google responded to the activity, performed an impact analysis and has completed email notifications to the potentially affected businesses,” Melanie Lombardi, head of Google Cloud Security Communications, said.
Cybersecurity analysts have linked the hack to individuals with ties to an alliance of cybercriminals called Scattered Lapsus$ Hunters.
Research group Unit 42 said in a note the group had “asserted responsibility for laying siege to customer Salesforce tenants as part of a coordinated effort to steal data and hold it for ransom.”
The hackers had reportedly set an October 10 deadline for ransom payment.
‘Oldest tricks in the book’
The hackers stole the sensitive data using a social engineering technique, referring to a tactic of manipulating victims by pretending to be a company representative or other trusted person, experts said.
The FBI last month issued a warning about such attacks targeting Salesforce.
The agency said hackers posing as IT workers had tricked customer support employees into granting them access to sensitive data.
“They have been very effective,” expert Hunt said.
“And it hasn’t been using any sophisticated technical exploits… they have exploited really the oldest tricks in the books.”
The hack of data from Australia’s biggest airline comes as a string of major cyberattacks in the country has raised concerns about the protection of personal data.
Qantas apologized last year after a glitch with its mobile app exposed some passengers’ names and travel details.
And major ports handling 40% of Australia’s freight trade ground to a halt in 2023 after hackers infiltrated computers belonging to operator DP World.
