Metal-organic frameworks with exceptionally high capacity for storage of carbon dioxide at room-temperature

Metal-organic frameworks that store 10+ CO₂ molecules per formula unit at room temperature unlock compact carbon capture.

What it is

This technology uses a metal-organic framework (MOF) packed in a container to adsorb and release CO₂ through a gas conduit at about 25°C. Its technical significance is the ability to store at least 10 CO₂ molecules per formula unit at room temperature, leveraging high MOF surface area for practical adsorption without cooling. Previously, building these MOF-based storage systems typically required negotiating licensing around specific MOF compositions and performance targets.

What you could build

Launch room-temperature CO₂ cartridge systems for building ventilation, point-source capture, and portable air-quality monitors.
