ZIFs zap CO2

“The technical challenge of selectively removing carbon dioxide has been overcome [by using Zeolitic Imidazolate Frameworks]. Now we have structures that can be tailored precisely to capture carbon dioxide and store it like a reservoir, as we have demonstrated. No carbon dioxide escapes. Nothing escapes — unless you want it to do so. We believe this to be a turning point in capturing carbon dioxide before it reaches the atmosphere.”

The reservoir is inside the zeolite structure. I’m still unclear how the zeolites would then be stored and how stable they are, ie what’s their “shelf life”?
