What do you think about our new web site?

Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Technology attempts to tackle climate change by freezing carbon

RATE THIS! +46

This August, President Obama announced  an ambitious plan to reduce carbon dioxide emissions by 32 percent by 2030. BYU professor Larry Baxter has created a carbon capture system that separates carbon dioxide from other gases (and prevents it from escaping into the air) by freezing and storing it. 

 
And while there are other ways to curb carbon emissions, Baxter’s cryogenic carbon-capture system gobbles up 99 percent of the CO2 from emissions and costs half as much as conventional methods.
 
“We took a completely different approach,” says Baxter, who spun the research into a startup that is predominantly funded by government grants and employs BYU grads and interns among others. “What if we cooled down the gas to the point that the CO2 condenses out of the air?”
 
After his system freezes the CO2 with,130 degree Celsius temperatures, it separates the dry ice from the gas and heats everything back up. The CO2 is pressurized to become a liquid so it can be stored safely in underground aquifers or storage facilities for later use, such as enhanced oil recovery.
 
Industry expert Carl Bauer said Baxter’s technology is a “technological game changer for CO2 capture.”
 
“Cryogenic separation of gases is not a newly discovered area of science, but what Dr. Baxter has done is develop a new approach to the process that significantly improves the energy and economic performance of cryogenic gas separation,” said Bauer, the former director of the National Energy Technology Laboratory.
 
In the latest of a series of publications on the process, Baxter provides a broad overview of the cryogenic carbon capture technology in a paper recently published in the International Journal of Greenhouse Gas Control.
 
While Baxter is confident in his technology, he hopes efforts to reduce carbon emissions in the U.S. will spur other nations to follow suit.
 
“Any real solution to this problem needs to be a global solution,” Baxter said. “Even if the U.S. fully complies with this new regulation (EPA’s Clean Power Plan), you won’t notice a change if we’re the only country doing it.”
 
Currently there is only one full-scale power plant in the world doing carbon capture: a facility in Saskatchewan, Canada, a government-supported demonstration using conventional methods. Right now, typical power plants across the worlds are generating about 10,000 tons of carbon dioxide a day that goes directly into our atmosphere.
 
Baxter’s team is working on getting his technology to the pilot stage, which is five times the current size of his working unit and 100 times the capacity. He estimates having his tech in a full-scale commercial facility within five years and operating within seven years.

Great! There are more and more proposed solutions how to capture CO2 and would help, however, preventing emission should be our priority Reply
