Atmospheric CO2 capturing device created

Canadian scientists have created a device that efficiently removes carbon dioxide from the atmosphere. Previous CO2 capturing devices have only functioned when they were installed close to the sources of emission (e.g. in a car, or inside a coal plant) to capture escaping greenhouse gasses, but the new technology can be placed (almost) anywhere on Earth. Expect to see greenhouse gas capturing plants in the near future.

University of Calgary team creates CO2 atmosphere-scrubbing machine.


An ever-present point of concern for the planet’s future welfare, worries over damaging CO2 emissions could soon be a thing of the past thanks to a University of Calgary climate change scientist who’s developed a machine capable of removing CO2 from the air.

More pointedly, David Keith and a team of researchers working out of the University of Calgary have been diligently looking for a way to capture harmful greenhouse gas carbon dioxide (CO2) directly from the air by utilising “near-commercial” technology.

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.”

According to Keith, the team is working hard to turn its scrub machine theory into an engineering reality in order to help cut down CO2 emissions produced from transportation-based diffuse sources such as vehicles and airplanes.

The proposed air capture system differs from existing carbon capture and storage (CCS) technology, which is already a contributing factor in the strategy of federal governments as they strive to reduce greenhouse gas emissions.

For example, while CCS involves installing equipment at, say, a coal-fired power plant to capture CO2 produced during the coal-burning process before then piping the emissions for permanent underground storage in a geological reservoir, air capture machines will be able to literally remove the CO2 present in ambient air everywhere.

In applying the technology, Keith offers that: “A company could, in principle, contract with an oilsands plant near Fort McMurray to remove CO2 from the air and could build its air capture plant wherever it’s cheapest -- China, for example -- and the same amount of CO2 would be removed.”

In demonstrating the technology in practice, Keith and his team used a custom-built tower to capture CO2 directly from the air while requiring less than 100 kilowatt-hours of electricity per tonne of carbon dioxide. The tower unit was able to capture the equivalent of approximately 20 tonnes per year of CO2 on a single square metre of scrubbing material -- which amounts to the average level of emissions produced by one person each year in North America.

While still in its early stages, the atmosphere-scrubbing technology has already been touted by environmentalists as an energy-efficient and cost-effective way to complement other approaches designed to help reduce transportation emissions, such as biofuels and electric engines.

It is the team’s future goal to see the technology further developed to the point where it can be used through commercial-scale facilities solely focused on removing CO2 emissions from the air.

I say tear down the remaining rainforests and throw these babies up!

Yes! With contemporary industrial design, we can make our Trees 2.0 (a.k.a. AtmoScrubbers) significantly better-looking dependencies than their progenitors!

Sounds like some pretty good technology that they've developed. We do some of that kind of stuff here where I work.

Instead of putting it in the ground, where it can eventually come back up, why not build a mass-driver and send it to Mars? I think Mars could use some greenhouse gasses.

This. Excellent idea.

I could have sworn there's such a device that does that being funded by the EU. It was out in an ocean or something.

That would be kinda stupid considering that you need to be somewhere you can do something with all that CO2.

Yea, I don't know how they're doing it, but I know they are.

Excellent article Chuser!

Maybe this will finally shut up the conservatives that don't even believe our predicament in a man-made issue.

How would it shut us up?

As it can be physically removed and we directly see a decline in greenhouse emissions. Having the facts displayed very blatently it will be hard to deny.

So the fact that we can remove CO2 from our atmosphere somehow proves that the tiny ammount we add has caused the global temperature to increase?

Hate to break it to you, but mankind has been removing CO2 from the atmosphere for decades if not centuries. It's a very usefull substance and is thus in a reasonable degree of demand.
