Carbon capture as a potential climate fix is nothing new, the basic idea being to grab CO2 before it ever reaches the atmosphere. The problem has always been the eye-watering cost of running the kit, which is why it hasn’t really scaled the way people hoped.
Most existing systems lean on a process called aqueous amine scrubbing, which means heating huge volumes of liquid past 100°C just to release the CO2 it’s captured.
That heating step is where the money disappears to. And it’s the bit a team at Chiba University in Japan has been chipping away at, with a new kind of carbon material they’re calling viciazites.
A material that lets go of CO2 at low heat
Solid carbon materials have already been on researchers’ radar as a cheaper alternative to liquid…
