Researchers have developed a new carbon capture system that they claim is the world’s fastest, and has an efficiency of 99 percent.

As carbon dioxide builds up in the atmosphere, it won’t be enough to simply curb our emissions – we’ll need to actively remove some of what we’ve already released. In a new advance, researchers from Tokyo Metropolitan University have developed a new compound that can reportedly remove carbon dioxide from ambient air with 99 percent efficiency and at least twice as fast as existing systems.
Direct air capture (DAC) technologies usually remove carbon dioxide by piping air or exhaust through some kind of filter or catalyst, including magnetic sponges, zeolite foam or materials made of clay or coffee grounds. Others bubble the air through a liquid, which can either absorb the CO2 or cause it to separate out into solid crystals or flakes.
The new compound falls into that last category, which are known as liquid-solid phase separation systems. While studying a series of liquid amine compounds, the Tokyo Metro team discovered one, called isophorone diamine (IPDA), was particularly effective at capturing carbon dioxide.
