Canadian Scientist Create CO2 Scrubber

- Adam Clare

A researcher from the University of Calgary has create a machine that essentially scrubs carbon dioxide from the atmosphere. The Tech Herald explains:

The team now believes it is close to achieving that goal with the development of a relatively simple machine that can capture, or “scrub” the trace amount of CO2 present in the air at any place on the planet.
“The climate problem is too big to solve easily with the tools we have,” explained Keith, director of the Institute for Sustainable Energy, Environment and Economy’s (ISEEE) Energy and Environmental Systems Group and a professor of chemical and petroleum engineering.
“While it’s important to get started doing things we know how to do, like wind power nuclear power and ‘regular’ carbon capture and storage, it’s also vital to start thinking about radical new ideas and approaches to solving this problem.”

Crystals Absorb CO2 Like a Sponge

This is pretty neat!

The CBC is reporting that a new form of crystal can capture CO2 in a way that seems like magic.

Chemists at the University of California Los Angeles said the crystals — which go by the name zeolitic imidazolate frameworks, or ZIFs — can be tailored to absorb and trap specific molecules.

“The technical challenge of selectively removing carbon dioxide has been overcome,” said UCLA chemistry professor Omar Yaghi in a statement.
The team of scientists created 25 ZIF crystal structures in a laboratory, three of which showed a particular affinity for capturing carbon dioxide. The highly porous crystals also had what the researchers called “extraordinary capacity for storing CO2”: one litre of the crystals could store about 83 litres of CO2.
