Its job? To capture carbon dioxide directly from the air and put it to use. The CO\u2082 it collects can be used in everyday ways: to carbonate drinks, to create methane for cooking on gas stoves, to promote plant growth, or even to be converted to electricity.<\/p>\n<p>This is the carbon neutral vision laid out in Kyushu University\u2019s exhibit, which is part of the \u201cFuture Society Showcase\u201d at Expo 2025, Osaka, Kansai, Japan, open from April 13 to October 13, 2025. The exhibit is installed in the largest demonstration carbon capture test plant in Japan, which visitors to Expo 2025 can <a href=\"https:\/\/rite.or.jp\/expo2025\/en\/\">tour by reservation<\/a>.<\/p>\n<p>Kyushu University\u2019s Direct Air Capture and Utilization device (known as DAC-U) is in development as part of a<a href=\"https:\/\/mozes.jp\/en\/\"> NEDO-Moonshot Project<\/a>, led by<a href=\"https:\/\/hyoka.ofc.kyushu-u.ac.jp\/html\/100025406_en.html\"> Professor Shigenori Fujikawa <\/a>from the <a href=\"https:\/\/i2cner.kyushu-u.ac.jp\/en\/\">International Institute for Carbon-Neutral Energy Research<\/a> (WPI-I\u00b2CNER) and <a href=\"https:\/\/k-nets.kyushu-u.ac.jp\/en\/\">Research Center for Negative Emissions Technologies<\/a> (K-NETs) at Kyushu University.<\/p>\n<p>DAC-U, along with other exhibited carbon capture technologies, is vital in the fight against climate change. CO\u2082 acts as a greenhouse gas that warms the planet, and its concentration in the atmosphere has risen sharply due to human activity, such as burning fossil fuels. Reducing this buildup, not only by lowering emissions but also by capturing CO\u2082 from the air, is essential for slowing global warming and creating a more sustainable future.<\/p>\n<p>However, Fujikawa emphasizes the importance of open thinking about CO\u2082. \u201cWe should not treat CO\u2082 as a villain. If captured and recycled responsibly instead of allowing it to accumulate, it can be a valuable resource that we can use in our daily lives,\u201d he says.<\/p>\n<p>As part of Kyushu University\u2019s exhibit, visitors can see a spinning disk that showcases the core of the technology behind DAC-U: an ultra-thin nanomembrane, 1\/300th the thickness of plastic wrap. This filter, inspired by the selectivity of cell membranes, lets CO\u2082 pass through more easily than other gases in air, allowing the carbon dioxide to be concentrated.<\/p>\n<div id=\"attachment_25708\" style=\"width: 418px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-25708\" decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-25708\" src=\"https:\/\/sdgs.kyushu-u.ac.jp\/kanri\/wp-content\/uploads\/2025\/05\/pc_page-2.jpg\" alt=\"\" width=\"408\" height=\"288\" srcset=\"https:\/\/sdgs.kyushu-u.ac.jp\/kanri\/wp-content\/uploads\/2025\/05\/pc_page-2.jpg 408w, https:\/\/sdgs.kyushu-u.ac.jp\/kanri\/wp-content\/uploads\/2025\/05\/pc_page-2-300x212.jpg 300w\" sizes=\"(max-width: 408px) 100vw, 408px\" \/><p id=\"caption-attachment-25708\" class=\"wp-caption-text\">Fig. 1. A prototype of Kyushu University\u2019s Direct Air Capture and Utilization (DAC-U) device and its ultra-thin nanomembrane is on display at Expo 2025, Osaka, Kansai, Japan. The machine on the right captures the carbon dioxide, which the machine on the left converts to usable fuels or chemicals.<\/p><\/div>\n<p>\u201cUsing ultra-thin synthetic membranes to filter the air is an innovative technology unlike any other,\u201d says Fujikawa.<\/p>\n<p>DAC-U\u2019s technology allows the research team to take a less conventional approach to carbon capture. Most current processes require significant amounts of land, money and energy. But as nanomembranes have lower energy requirements for capturing CO\u2082, Fujikawa is able to focus on developing small-scale, decentralized carbon capture that can take place even in densely populated cities like those in Japan, where large plots of land are scarce.<\/p>\n<p>\u201cOur message is that CO\u2082 capture can be ubiquitous\u2014it can happen anywhere and anytime, in a school, factory or home,\u201d says Fujikawa.<\/p>\n<p>Fujikawa\u2019s team is currently working on reducing the size of the machine, while improving its efficiency. The ultimate goal is for the machine to be able to meet the energy needs of an average household.<\/p>\n<p>\u201cThe key is local production, local consumption. By capturing and recycling carbon on a local scale, this brings us one step closer to achieving a carbon-neutral society,\u201d says Fujikawa.<\/p>\n<div id=\"attachment_25706\" style=\"width: 310px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-25706\" decoding=\"async\" loading=\"lazy\" class=\"size-medium wp-image-25706\" src=\"https:\/\/sdgs.kyushu-u.ac.jp\/kanri\/wp-content\/uploads\/2025\/05\/pc_page-3-300x213.jpg\" alt=\"\" width=\"300\" height=\"213\" srcset=\"https:\/\/sdgs.kyushu-u.ac.jp\/kanri\/wp-content\/uploads\/2025\/05\/pc_page-3-300x213.jpg 300w, https:\/\/sdgs.kyushu-u.ac.jp\/kanri\/wp-content\/uploads\/2025\/05\/pc_page-3-380x270.jpg 380w, https:\/\/sdgs.kyushu-u.ac.jp\/kanri\/wp-content\/uploads\/2025\/05\/pc_page-3.jpg 408w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><p id=\"caption-attachment-25706\" class=\"wp-caption-text\">Fig. 2.
