So let's start with a big caveat: it's very early days for this type of technology and there are a lot of unknowns with regards to scale and effectiveness.

That being said, this looks very promising:

I've also added the Guardian article below if people prefer that [1].

It's known as a "covalent organic framework" but essentially it's a powder which at the atomic level can take carbon from the atmosphere and store it internally. This carbon can then be released by heating to 140F and used in industrial processes. This is good because the heat cycle is far cooler than existing technologies and the substance can be used up to 200 times to capture and release carbon.

Researchers state that 200g of the powder can absorb the same amount of CO2 in a year as a large tree and given we already require the CO2 for industrial processes this would be a good way to remove CO2 from the atmosphere and then use it in industrial processes.

This means it's more something to head towards carbon neutrality rather than absolute reduction in my mind but every little is going to help given we aren't going to stop using CO2 in industrial processes.

Interesting and encouraging although the science bit went way over my head!

Trouble with all the mechanical (and I include chemical synthesis under that umbrella) proposals is that it is always early days and we may not have many thousands of days left to make an impact. And they focus on carbon dioxide all too often without considering the increasing risk from methane. The danger being that their small impact will distract from the much more beneficial courses of action that will result from adjusting our manufacturing, farming, lifestyle and transport practices to minimise the causes of manmade climate damage (well, damage to our own and many other species although these practices may benefit some species that will be enabled to predate upon us to a greater degree.) Balance is difficult.

The world really needs to go heavily plant based. People need to get out of the habit of having animal products at every meal.

Some interesting work being done here on using seawater and lowering pH to remove the CO2. The OP one seems to have similarly good science behind it.

Lots of speculative tech out there but increasingly it seems to be used in Integrated Assessment Models (IAM's) to find a path back to 1.5C. Overshoot is now virtually unavoidable and these technologies allow modellers to assume we can get back to a safer level of warming. No doubt the reason the current UK Government was so quick to announce Carbon Capture Utilisation and Storage (CCUS) as one of their cornerstone strategies despite much consternation from climate scientists.
