It’s also the amount of Co2 captured by roughly 10000 trees in a year - with apparently around 1.2 million being planted in Australia each day. I’m no expert, but I do think trees are a slightly cheaper and simpler solution for creating stuff with captured carbon.
Aka wood.
Sure but every tree you plant takes up space and there is a limit how much you can do this. Unless you then farm them and store th carbon long term somehow
Australia isn’t exactly going to be running out of space for forests any time soon. They are going to run out of forests if they keep it up though, cutting roughly 55 million tonnes of co2 worth of trees annually.
Kinda doubt it makes much sense to be building 22 000 carbon capture plants a year just to break even, instead of replanting the trees.
Making a cubic metre of concrete creates almost half a ton of Co2, so it will take years if not decades for the plant to even make up being built. A tree starts capturing immediately and keeps doing so for decades all by itself.
In theory. Nobody actually manufactures it yet in any quantity, and it will take a long time to be able to replace even a measurable fraction of the 30 billion tons the world uses annually.
An alternative way to look at it is that we should focus on the solutions that actually make sense. Carbon capture is like plastic recycling, the solution to it isn’t to try to recycle harder, it’s to reduce the use of plastics so we don’t have anything to recycle.
Also, do you know what the majority of the captured Co2 is currently used? To extract oil.

Build one of these in a year, or plant 10 thousand trees and wait decades for them to grow…

Carbon neutral concrete exists.

So let’s just give up because it’s a tough engineering problem, right?
People need to stop letting perfect be the enemy of good.
