Direct Air Capture Plant

Interactive 3D simulation of a direct air capture (DAC) plant: fans push ambient air through solid-sorbent contactor banks that adsorb CO2, which is then released by heating (regeneration) and piped to storage — watch saturation, capture rate and energy cost respond to your controls.

Direct air capture (DAC) pulls carbon dioxide straight out of the open atmosphere rather than from a concentrated industrial flue stream — a much harder chemistry problem since CO₂ makes up only about 0.042% of ordinary air. This simulation models a solid-sorbent DAC plant with two alternating contactor banks: one bank adsorbs CO₂ from air pushed through it by fans while the other is sealed and heated to release its captured CO₂ for storage, then the roles swap. Adjust fan speed, ambient concentration, regeneration temperature and sorbent capacity to see how each one trades off capture rate against the energy cost per tonne of CO₂ removed.

⚙ Under the hood

Interactive 3D simulation of a solid-sorbent direct air capture (DAC) plant: two contactor banks alternate between adsorbing CO2 from air pushed through by fans and being heated to release it for storage, with fan speed, ambient CO2 level, regeneration temperature and sorbent capacity all changing the capture rate and energy cost per tonne.
