Steel startup aims to keep Sweden's green industry dream alive
Just outside the town of Boden in Sweden's far north a massive worksite is teeming with activity.
The metal skeletons rising out of the ground hint at the brand new mill which will produce steel using technology that the company says gives off 95 percent less CO2 emissions than traditional methods.
"Right now, we got the pole position," Denis Hennessy, Stegra's vice president for steel, said during a site tour.
"We're in a very unique position to do some things first in the industry," Hennessy said as he described the benefits of building a completely new plant.
Among heavy industries, iron and steel production is the number one CO2 emitter, according to the International Energy Agency.
The traditional process gives off nearly two tonnes of CO2 for every tonne of steel made.
Hydrogen
The iron ore that comes out of a mine is usually rich in oxides, chemical compounds made up of iron and oxygen, and this oxygen has to be removed -- usually by heating it with coke in a blast furnace -- which is when most of the CO2 is released.
Stegra will remove the oxygen by circulating heated hydrogen gas which binds the oxygen -- creating water as a byproduct
The hydrogen is also to be produced on site at an electrolyzer plant powered by renewable energy.
Access to cheap renewable energy, such as hydro power in Sweden's north, is key to Stegra's business model, according to CEO Henrik Henriksson.
He told a group of investors and reporters that most established European steel firms are paying three times as much for their electricity.
"That gives us a relatively huge cost advantage," he added.
While traditional steelmaking is still cheaper, Stegra thinks it will benefit by being able to charge a premium for "green" steel.
When the company first announced plans for a new plant in 2021, it was called H2 Green Steel and had an ambitious target of starting production in 2024. It also aimed for annual output of five million tonnes of steel -- more than all of Sweden's current annual output -- by 2030.
Northvolt's shadow
It is now targeting to turn on the mills in the second half of 2026, with an initial capacity of 2.5 million tonnes of steel per year, which they hope to eventually double.
This is a still a drop in the ocean compared to the near 1.9 billion tonnes of steel shipped worldwide in 2024, according to the World Steel Association.
Behind Stegra is investment firm Vargas Holding, which was also a co-founder of battery maker Northvolt.
Northvolt was seen as a cornerstone in European efforts to catch up with Chinese battery producers before production delays and a debt mountain led it to declare bankruptcy in March.
As Northvolt was seen as a leader in a green industrial boom in Sweden, its demise has dampened optimism.
A review by Dagens Arbete, a magazine published by three labour unions, found that 20 out 30 "green industrial projects" in Sweden were either delayed or had been cancelled.
Stegra also has detractors.
Magnus Henrekson, a professor at the Research Institute of Industrial Economics (IFN), told AFP that the first problem with the startup was the inland location without the infrastructure to transport large amounts of steel to nearby ports.
"And this is to be done by a startup, without previous experience of steel production," Henrekson said, adding that he thought that given Stegra's massive power needs, it was over optimistic to think electricity prices would remain competitive.
No Chinese competitor
Henrekson also noted that there are signs that the wider steel industry has lost faith in hydrogen reduced iron, highlighting ArcelorMittal's announcement in November that it was holding off decisions on several direct reduction plants -- citing both market and technology concerns.
Despite the challenges, Stegra's Henriksson stressed that the company was "different" from Northvolt.
"We are a different team. We are a different setup," he said, adding that there was "no green steel business" in China to provide competition.
Henriksson also said that a key difference was also steel as a product was much different from battery packs for vehicles -- which require customers to adapt software, technology and design.
Producers who want to reduce their carbon footprint can simply use Stegra's steel, he said.

Europeans are buying frozen food to reduce waste, survey shows
Sustainability is playing a bigger role in how people shop, but does that influence what they buy in the frozen food aisle? A new survey from Europe's largest frozen food company suggests yes. Nearly half of European consumers (47 per cent) are opting for frozen food products to reduce food wastage, according to Nomad Foods, owner of Birds Eye, Findus and other household brands. Almost 59 million tonnes of food waste are generated annually in the EU, according to the European Consumer Organisation. So, in the words of one UK supermarket giant, every little helps. But what difference does buying frozen make exactly, and which countries are embracing it? How does frozen food help reduce waste? It's obvious, really - that freezing food preserves it for longer, meaning less needs to be thrown away and bought. When food goes to waste, it is not only the food itself that is lost, but also the resources used in production and transportation, including fuel, water, land, labour, fertilisers, and packaging. And as food breaks down in landfills, it produces methane - a potent greenhouse gas. 'In 2021 and 2022 combined, food waste accounted for around 18m tonnes of GHG emissions in the UK,' says Ben Ashmore, head of external affairs at FareShare, a charity which works across the food industry to help identify and redistribute surplus food. 'By redistributing surplus food to people, and making it longer-lasting through freezing, we can help reduce food waste and the associated emissions, while helping people in need." There are many reasons why people are leaning more heavily on the freezers, but Nomad Foods' inaugural 'Frozen in Focus' report indicates that sustainability is a prominent factor. 'The freezer is no longer just a place to store food; it's becoming the cornerstone of a more efficient, sustainable, and nutritious lifestyle,' claims Stéfan Descheemaeker, CEO at the UK-headquartered company. The UK leads the way on the food waste front, according to the new multi-market study of 7,500 adults. Nearly 60 per cent of Brits prefer to buy frozen food as it reduces food waste. That figure is followed by 50 per cent in Italy, 49 per cent in France, 43 per cent in Sweden, and 44 per cent in Germany. A smaller, but still significant portion of consumers recognise the potential of frozen food to contribute to more sustainable food chains. 15 per cent in Sweden, 7 per cent in Italy, 9 per cent in the UK, 8 per cent in Germany, and 7 per cent in France agreed with this statement. 'European consumers are increasingly aware of the link between food waste and sustainability,' says David Pettet, head of sustainability at Nomad Foods. 'Freezing food isn't just about convenience; it's a powerful tool for preserving freshness, maximizing resources, and building a more sustainable food system.' Reducing the energy consumption of freezers Research is also going into making the freezer itself a more eco-friendly space, given the significant energy usage and associated emissions of the always-on appliances. Launched in 2023 at COP28, the Move to -15°C Coalition aims to make a difference in food supply chains by "resetting frozen food temperature standards". Featuring big names, like shipping giant Maersk and supermarkets Iceland and Morrisons, the coalition challenges the received wisdom that -18°C is the correct freezer temperature. Studies have shown that -15°C works too, and can deliver significant energy savings. One recent study from Campden BRI, a food and drink research centre, and Nomad Foods found that a 3°C increase in frozen food storage temperatures could reduce freezer energy consumption by 10 per cent, with no significant change in most products.

In China, coins and banknotes have all but disappeared
You have to get up early if you have any hope of spotting them, and you must stay alert to identify them in the aisles. At the Xinmin fresh produce and vegetable market, located in the heart of Beijing just North of the 2 nd Ring Road, the oldest customers are now the last to keep using coins and banknotes, which are vanishing from the rest of Chinese society. The world's second-largest economy has undergone rapid digitization, and all daily transactions – from supermarkets to cafés, taxis to public transportation – are now made with one of two apps that have become vital to life in China: WeChat or Alipay. Their green and blue logos are displayed at every payment point, and many businesses no longer even keep a traditional cash register, but instead simply scan the QR code presented by the customer. Many taxis refuse cash payments, as do many neighborhood grocery stores, which often do not have the change to give back in any case. Ma Dian, a fruit and vegetable vendor from Hubei who works at this covered market in the capital, observed that the trend surged abruptly over the past decade, becoming what he calls a "radical change." "I still accept cash only to help the very elderly. Below the age of 80, almost everyone has switched; above that, it's much harder to adapt," he said while promoting his Dalian blueberries.

Jeff Bezos weds Lauren Sánchez in lavish Venice ceremony
Billionaire Jeff Bezos and Lauren Sánchez tied the knot in a wedding ceremony on the island of San Giorgio Maggiore in Venice on Friday. Sánchez posted a photo to her Instagram of herself beaming in a white gown as she stood alongside tuxedo-clad Bezos, the world's fourth-richest man. Dozens of private jets flocked to Venice's airports and yachts pulled into the city's waterways as guests arrived for the ceremony. Celebrities including members of the Kardashian family as well as Oprah Winfrey were in Venice to attend the wedding. It was the second day of events spread across the Italian lagoon city. On Friday afternoon, Sánchez emerged from her hotel wearing a silk scarf on her head and blew a kiss to journalists before stepping into her water taxi. It carried her through the canals to San Giorgio island, across the lagoon basin from St. Mark's Square, where the couple reportedly held their wedding ceremony. The wedding has divided the Italian city. Some activists protest it as exploitation of Venice by Bezos while ordinary residents suffer from over tourism, high housing costs and the constant threat of climate-induced flooding. About a dozen Venetian organisations, including housing advocates, anti-cruise ship campaigners and university groups, have united to protest the multi-day wedding under the banner 'No Space For Bezos.' Protesters have staged small-scale protests, unfurling anti-Bezos banners on iconic Venetian landmarks. Critics cite Amazon's labour practices, ongoing tax disputes with European governments and Bezos' political associates as reasons for concern. The city's governor Luca Zaia has strongly defended the wedding as an economic and reputation boon for Venice, saying the price tag he had seen was between €40 million and €48 million. Bezos donated 1 million each to three environmental research organisations working to preserve Venice, according to Corila, the Venetian environmental research association.
