The first \u201cCO<sub>2 <\/sub>scrubbers\u201d tried in smokestacks used amines dissolved in water to do this, but solid amines are used in all kinds of carbon-capture systems now because they require less energy. These solid materials\u2014often made into granules similar to the activated carbon in a water filter\u2014have high surface area and high porosity, so the amines can efficiently partner up with CO<sub>2 <\/sub>molecules.<\/p>\n<p><a href=\"https:\/\/arstechnica.com\/science\/2026\/06\/your-empty-cuppa-could-capture-carbon\/\">Read full article<\/a><\/p>\n<p><a href=\"https:\/\/arstechnica.com\/science\/2026\/06\/your-empty-cuppa-could-capture-carbon\/#comments\">Comments<\/a><\/p>\n<p style=\"margin-top:1.5em;\"><a href=\"https:\/\/arstechnica.com\/science\/2026\/06\/your-empty-cuppa-could-capture-carbon\/\" target=\"_blank\" rel=\"noopener\">Read the full article &rarr;<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scott K.
