Posted May 08, 2019 04:10:37With the recent introduction of a carbon-capture facility in Utah, some scientists are wondering whether carbon dioxide can be stored as CO2 in cubes.
The cube storage concept is a relatively new one, and the first commercially available cube-based CO2 storage solution was developed by the University of Utah.
But it may not be a panacea for climate change.
Culvert and colleagues at the University and University of Texas at Austin, along with colleagues from the National Center for Atmospheric Research and the Lawrence Berkeley National Laboratory, report that a cube-like storage system could increase CO2 concentrations in an ice cube by up to 25 percent, but would only be useful for cubes with low atmospheric pressure, or when the cube has low CO2 levels.
Celastrator cubes have been shown to have a low-oxygen, high-temperature structure that helps them store a large amount of CO2, but the researchers are unsure whether this is due to their internal structure or to the nature of the cubes themselves.
The researchers say that their research suggests that the cube storage system has the potential to be useful in a number of applications, including the construction of ice storage tanks, airtight sealed containers for storing CO2-capturing equipment, and storage for future storage of other materials, such as water.
The paper is published in the Journal of the American Chemical Society.

The idea is to capture carbon dioxide in the form of CO 2 , but with the right amount of carbon dioxide, the process could be extremely efficient.
But in recent years, some researchers have questioned whether the carbon capture process can effectively capture CO 2 without reducing the amount of the gas in the air.
Now, a new study from the University at Albany, the University in Utah and the University College London suggests that carbon dioxide storage systems are more than just efficient and carbon capture is actually more expensive than it sounds.
The team reports on the cost-effectiveness of carbon storage in ice cubes.
They find that the cost of carbon capturing in a cube of about 5 feet by 3 feet would be $0.36 per cubic meter, but when a cube has a pressure of 1,000 psi, the cost per cubic foot is $0,532.
Cubes that have high levels of CO-2 are considered “capture targets” and could be placed in the freezer for use as carbon capture equipment.
But the researchers found that carbon capture can be more expensive when it comes to CO2 that has been stored in cubes that have a high pressure and low temperature.
The reason that carbon storage can be cheaper is that carbon-neutral storage systems use water to trap the gas, rather than CO2.
The researchers found it would cost $0 to store 1,500 cubic meters of CO, but a cube with a pressure higher than 1,600 psi would cost about $1,821.
The authors suggest that this cost savings could be a benefit to consumers, but not a benefit for climate activists.
“This finding indicates that carbon is more costly than previously believed to be captured in cubes,” the researchers write.
“But the current cost-benefit analysis assumes that the cubes are not capturing CO2 and that there are no adverse effects associated with the storage of the carbon.”
The researchers suggest that carbon captures may be better suited for small-scale applications such as airtight seal containers or ice-cooled refrigerators.
But this may not translate to large-scale storage systems.
The research team also suggests that a carbon capture method that uses water to store the gas could be more cost-effective than carbon capture systems that use CO2 directly.
The carbon capture methods they used to evaluate the costs and benefits of carbon sequestration systems for a cube storage storage system are detailed in a new paper published in Nature Communications.
The Cornell-led group used a three-dimensional (3D) model to compare the cost and benefits associated with different methods of carbon release.
The cost-benefits of carbon-reducing methods were evaluated by comparing the costs of a cube based on a cube that has a low pressure to one that has one of these same conditions.
Celtic Cube Storage Systems (CCSS)The researchers estimate that the average cost of a Cube-Based Carbon Capture System is $1.03 per cubic m, with the cost increasing to $2.13 per cubic metric in the high-pressure cube.
The cost-advantages are more complex.
The CCSS costs $1 per cubic meters and $2 per cubic centimeters.
The efficiency is 30 percent, while the cost increases to nearly 60 percent
