This Concrete Block is Captured CO2

These concrete blocks are actually captured carbon emissions. A company called CarbonQuest has started a carbon capture system on a 30-story apartment tower in Manhattan. Here's how it works...

YouTube has a "don't recommend this channel" option, but they don't have a "only recommend this channel" option smh

There is a natural rock called dunite that captures CO2 just by exposure to atmosphere. Tons of it are needed and thousands of square meters need to be covered with it. But there is enough of that rock, mining if easy (at least one big mine in Spain), and the final cost once deployed is smaller than the cost per ton that is being currently paid as fines for excess of emission.

If only making cement didn’t create so much co2…

[wuhaoh]

Cement, the main ingredient of this approach, emits lots of CO2 to produce... It's created by heating up rocks (CO2 emissions) to release CO2 embedded in the rocks (CO2 emissions again). So this process is net carbon positive...

[thomasowens]

Normal concrete doesn't need a boiler !!!

[nicholasgoldsborough]

Do we know how much energy we're using to recapture the emissions to convert it to a liquid, Trucked to a concrete factory then Trucked back out to new buildings?

[THE_Dr.Pepper_Ethusiast]

This is cool, but I worry that if a structure constructed with these carbon materials is destroyed that the carbon emissions inside would be released. Yes they may have cooled the carbon emissions into a liquid but if they block was broken open couldn’t the heat warm the carbon emissions inside back into a gas?

[Htehtoom]

Probably not worth it, since cement produces an absolute ton of CO2 when made.

[parthgoyal]

What happens when the building catches fire? 😂

[CrapE_DM]

This feels like a scam to me. Concrete is one of the biggest producers of CO2, so I jave no reason to believe that that CO2 isn't also just being released when the blocks are made.

[beepboopbeepp]

Great except when they one day tear it down all that shit will be released back

[mysupernamegoeshere]

What about the process to make the blocks though? Is its impact low enough to yield a net carbon capture? I haven't been able to find an LCA or study on the process :(

[staticostrich]

Concrete is a major supplier of CO2 emissions. I have also seen people make a type of concrete that doesn't require CO2 to be released. I see this as an absolute win.

[alexplosion_ITA]

I like this idea, but doesn't this make those bricks more flammable since they're basically coal-enriched?
I could be totally wrong but I'm very curious

[FreelyFooled]

Carbon capture is wildly inefficient, society as a whole needs heavy lifestyle changes to reverse the effects of climate change.

[Maknanimous]

I really like that I can learn something new basically every time I click on one of these. It's like a fact of the day format but much more interesting.

[kneelesh]

They could also plant trees and capture CO2 inside woods which can be used to make houses.

[tomislavbelacic]

Why is see this as a big failure when all cons are realized 20 years from now?

[Gamuray]

Or just... Stop using a gas boiler. Then you cut your emissions from gas boilers to... Oh, right, nothing.

[nomyafiftyonefifty]

Trees and plants do it for no cost.
And they need CO2 to survive.
