The general consensus outside tech bros and climate deniers is that CCS projects are bullshit. I'm sure you will find a bunch of researchers willing to say otherwise, it was just the same for cigarettes, alcohol, abestos, etc. I'm sure their labs are well funded too.

The change in CO2 concentration in the air is relatively small in spite of its effect on climate, so I doubt it can cause a change in itself (like doping photosynthesis). The change in temperatures and humidity seems to have negative effects overall (wildfires, droughts).

Planting trees to turn into biomass doesn't really work in practice because they burn from wildfires. Also, we need the land for agriculture because the yields are dropping. Moreover, the wood is burnt as an energy source the moment its price becomes competitive against oil, which is increasingly likely to happen in the future (especially if your country doesn't produce its oil).

Sorry if I sound like a downer, have a nice day nonetheless.

As far as I know, the easiest ways are still:

1. Plant some fast-growing plants
2. Harvest them
3. Bury the biomass or convert it to biochar and bury that

Repeat.

I do a bio carbon capture project using algae. narcimalgae on YouTube if you want to check it out.

Using primitive and slow methods still better than one-off projects with exotic materials and huge power demands.
