The world’s largest plant that sucks carbon dioxide directly from the air and deposits it underground started operating on Wednesday last week, the company behind the nascent green technology said.
Swiss start-up Climeworks AG, which specializes in capturing carbon dioxide directly from the air, has partnered with Icelandic carbon storage firm Carbfix to develop a plant that sucks out up to 4,000 tonnes of CO2 per year. That’s the equivalent of the annual emissions from about 790 cars. Last year, global CO2 emissions totaled 31.5 billion tonnes, according to the International Energy Agency.
Direct air capture is one of the few technologies extracting carbon dioxide from the atmosphere and it is viewed by scientists as vital to limit global warming, blamed for causing more heatwaves, wildfires, floods and rising sea levels.

The Orca plant, a reference to the Icelandic word for energy, consists of eight large containers similar in looks to those used in the shipping industry, which employ high-tech filters and fans to extract carbon dioxide. The isolated carbon is then mixed with water and pumped deep underground, where it slowly turns into rock. Both technologies are powered by renewable energy sourced from a nearby geothermal power plant.
Direct air capture is still a fledgling and costly technology, but developers hope to drive down prices by scaling up as more companies and consumers look to reduce their carbon footprint.
There are currently 15 direct air capture plants operating worldwide, capturing more than 9,000 tonnes of CO2 per year, according to the IEA. US oil firm Occidental is currently developing the largest direct-air-capture facility, to pull 1 million tonnes per year of carbon dioxide from the open air near some of its Texas oilfields.
The blow caused to the airline industry by the COVID-19 pandemic has been especially felt by budget airlines, which mostly operate narrow-bodied passenger jets and have therefore been unable to develop a sideline in air freight during the pandemic. According to one academic’s analysis, when the outbreak stabilizes, businesses are targeting a trend in so-called “revenge travel.” However, she also hopes that, rather than the pre-pandemic price wars between budget airlines, the consolidation that has taken place during the pandemic will restore healthy competition in the industry. According to associate professor Melody Dai of National Cheng Kung University’s Department of Transportation
Many people choose to drink coffee for refreshment when they feel weary, but it would be wrong to think that coffee is the only thing that contains caffeine. There is caffeine in tea, cocoa, cola drinks and so on. Is caffeine good or bad for your health? Nutritionists say that getting an appropriate amount of caffeine can promote gastrointestinal peristalsis and perk you up, but remember not to take too much, otherwise it may put even more strain on your body. On Aug. 24, nutritionist Yu Chu-ching wrote a post on her “Julie dietician” Facebook page, saying that the main benefits of
A: Do you need anything from the stationery store? I’m going to town this afternoon. B: I can’t think of anything right now; I’ll message you if I think of something later. What are you going for? A: I’m going to choose a nice card for my nephew. He’s just graduated, and I want to say congratulations. B: Can’t you just send him a message through social media? It’ll save you a lot of time. A: 你有需要什麼文具嗎？我今天下午會上街唷。 B: 我現在想不起來，等一下如果想到了再傳訊給你。你上街幹嘛？ A: 我要幫姪子選一張好看的賀卡，他剛畢業了，我想恭喜他。 B: 你就不能在社群媒體上傳訊給他嗎？這樣還能節省很多時間。 （Paul Cooper, Taipei Times／台北時報張聖恩譯） Audio recordings for Speak Up! dialogues will be suspended until further notice due to
The new Marvel film “Shang-chi and the Legend of the 10 Rings” smashed the record for Labor Day opening weekend with US$71.4 million (NT$2 billion) in North America. The movie featuring Marvel’s first leading Asian superhero Shang-chi scored the second-highest opening in the pandemic, after Marvel’s “Black Widow.” The blockbuster film stars Chinese-Canadian actor Simu Liu alongside Golden Globe-winning actress Awkwafina and Asian superstars Tony Leung and Michelle Yeoh.
