This sums it up pretty well

Literally all ideas about carbon capture are quickly revealed to be cynical greenwashing if you think about one simple thing: how much CO2 do we need to store to offset global emissions?

The answer is that we need to store almost 40B tonnes of CO2, or around 10B tonnes of C if we break that down, every year. That’s something on the order of 1500 great pyramids of Giza (which weighs 6M tonnes) worth of carbon every year.

Wouldn’t it be more efficient to just grow algae, bamboo, hemp, sugarcane etc. and throw it in a hole somewhere?

Word of the day of, Green-washing.

There’s no way this will ever be economical at the scale we need to fix what we’ve done.

We already have that, it’s called trees 🤦‍♂️

pretty sure this is touched on here, fracking does damage to the place you want to store this CO2. I’m not totally sure this is going to work, at least, as proposed.

sounds like orc mischief to me
