Easily synthesized chemical filter could stop the greenhouse gas from reaching the atmosphere. How can carbon dioxide, a greenhouse gas, be removed from the exhaust of fossil fuel power plants before it ever enters the atmosphere? New research findings suggest that a promising answer lies in a si
are attributable to coal-fired power plants. Even as the world embraces other energy sources such as solar and wind power that do not generate greenhouse gases, finding a way to reduce the carbon output of existing plants could help mitigate their effects while they remain in operation.from flue gas before it reaches the atmosphere in the first place. However, it has proved challenging to create an effective scrubber.
“Put it all together, you need some kind of wonder material,” Evans said. “Here, we’ve managed to tick every box except stability in very humid conditions. However, using ALF would be inexpensive enough that a drying step becomes a viable option.”, two chemicals that are abundant and readily available on the market. It would cost less than a dollar per kilogram, Evans said, which is up to 100 times less expensive than other materials with similar performance.
On a microscopic scale, ALF resembles a three-dimensional wire cage with innumerable small holes. These holes are just large enough to allow COmolecules to enter and get trapped, but just small enough to exclude the slightly larger nitrogen molecules that make up the majority of flue gas.
Despite its potential, ALF is not ready for immediate use. Engineers would need to design a procedure to create ALF at large scales. A coal-fired plant would also need a compatible process to reduce the humidity of the flue gas before scrubbing it. Evans said that a great deal is already understood about how to address these issues, and that they would not make the cost of using ALF prohibitive.
“There is a great deal of research going on nowadays into the problem of what to do with all the captured CO,” Evans said. “It seems possible that we could eventually use solar energy to split hydrogen from water, and then combine that hydrogen with the COReference: “Aluminum formate, Alcapture” by Hayden A.
