Commonwealth Scientific and Industrial Research Organization, Australia's national science agency, talked up a new technology called Airthena in a release this week. "Airthena captures CO2 directly from the air using tiny sponges known as metal-organic frameworks (MOFs), and can be scaled up for commercial production," CSIRO said.
Airthena opens up the possibility of small-scale CO2 production on site. This could be useful for everything from beverage carbonation (yes, beer) to greenhouses.
The innovation could offer a low-cost alternative to the production and transportation of carbon dioxide using current methods.
This tech isn't the answer to our growing greenhouse-gas problem, though. "While Airthena won't make any immediate impact on cutting global CO2 emissions due to its scale, it will help businesses with a more reliable source of the gas for their everyday operations, while reducing their carbon footprint," CSIRO said.
