How we capture CO2 at the Amager Bakke power plant in Copenhagen

Carbon capture is the process by which CO2 is scrubbed from flue gas using a liquid with basic amines. The captured CO2 can either be stored or recycled as fuel.
When utilized at a waste-to-energy plant such as Amager Bakke (CopenHill), carbon capture actively reduces the amount of carbon dioxide in the atmosphere. In this way, carbon capture can be an important short term tool to fight global warming.

How much CO2 is it left in a rest product of a kilo? Or is all insert convert to pure air?

Once the CO2 is concentrated how is it sequestered? If used in carbonated beverages, what CO2 suppler is this displacing? How is this reducing net global CO2 annual emissions?

It can be methanated to replace natural gas or injected into the underground.

@@placeholdername0000 Yes, this could be what happens but does it? The point of my question is how does this help address climate change? The video only talks about an establish process for capturing CO2 from exhaust gases. It does not explain how the captured CO2 "actively reduces the amount of carbon dioxide in the atmosphere". (quote from video description) Pre-incineration the feed stock (waste) has an estimated future GHG emission value. Combustion of the waste generates higher levels of GHG emissions in the atmosphere than landfilling the waste. The process of incineration front loads when these emission are released while the heat from combustion is used to generate electricity. Capturing some of the CO2 from the exhaust gases could reduce the front loading of these emissions is sequestered. If the CO2 is used to carbonate beverages, used in enhanced oil extractions or improperly sequestered, its release at a later date still adds to GHG levels in the atmosphere. Capturing CO2 from combustion does not "actively reduce the amount of carbon dioxide in the atmosphere". Only capturing CO2 directly from the atmosphere does this when the concentrated CO2 is properly sequestered. Incineration can have land use benefits but the exhaust gases are very harmful to human health. It is great to see they are capturing CO2 and I assume the PM 2.5, SO2, NOx and other harmful compounds. What is not happening is a reduction of CO2 in the atmosphere. Mitigated harm at best. We (the world at large) need to be honest about our impact on the environment. Often any effort to reduce harm is over stated as in this video. Be proud that you doing less harm but don't say you're healing when you're not.

@@Bfould3120 The trash contains wastes such as paper and other materials that are biological in origin. These got their carbon from the atmosphere. Thus if you capture this you could become net negative.

@@placeholdername0000 Sorry not how it works. Making paper emits between 600 to 2000 kg CO2eq per metric ton of paper product. Then combustion of the paper releases the stored carbon. The CO2 capture process described in the video only collects a fraction of the CO2 released during combustion. So again this is not a carbon negative process even if the captured CO2 is properly sequestered. Cutting down a tree and burying it so deep that the decomposition gases can't escape would be net negative emissions. The issue is all the production and transport related to paper uses large amounts of fossil fuels. Also municipal waste contains a lot of disposable plastic made from petroleum and this is a large component of the exhaust gases. Again capturing the CO2 from the exhaust gases reduces the harm, it does not reduce CO2 in the atmosphere.

It is potentially possible to make a high fire kiln out of Styrofoam cooled by water though might need structurally reinforced. Like that could float on hot lava. Or, to melt a thread system together from the wide diameter cylinder section of a plastic bottle. With aluminum foil in between layers and around a preformed stud so the plastic doesn't stick and can be unscrewed. Further, reuse of our most stable and sanitary material can save heatwork. If not for society in general maybe for the Bush people for starters. greyishgreblum, "Pottery tap and die"💜

How about ice core samples show that it is temperature that raises c02 levels, not the other way around. That’s why my beer goes flat at the beach in the summer, and stays all bubbly ice fishing.

Recycling waste (as I do) has little connection with co2. She should learn how to pronounce amines. What happens to the separated co2? How are the amines manufactured? Carbon dioxide is the gas of life. Remove it all from the atmosphere and everything (including you) does eventually.

CO2 even at 800ppm wouldn't change global temp higher than 1% by it's low significance as GHG, it's around 400ppm sth now, plus it's plant fertilizer and not a pollutant. It's even essential to us to regulate our respiratory system. Water vapour/ clouds are the most potent GHG. Nevertheless, this is interesting tech. However there are actual pollutants in our emissions, most sulfur or nitrogen based compounds causing smog and acid rain. I wish the world could've risen beyond this consensus to actually investigate what really causes oceanic acidity (as carbonic acid is too mild slow acid), sea level and global mean temp to rise. The factual science behind global warming is being Misled. Yes that's what you get for being in my recommendations. Cheers

Thats not True my friend, this process itself is quite energy consuming, so if you use fossil energy to Power this process, you are not doing very much.
